PHONE USER INTERFACE

[0001] This application claims the benefit of priority of U.S. Provisional Patent Application Ser. No. 62/044,939, entitled “PHONE USER INTERFACE,” filed Sep. 2, 2014; and U.S. Provisional Patent Application Ser. No. 62/129,853, entitled “PHONE USER INTERFACE,” filed Mar. 8, 2015. The content of these applications is hereby incorporated by reference in its entirety.

[0002] The present disclosure relates generally to computer user interfaces, and more specifically to user interfaces for carrying on phone calls.

[0003] Some techniques for controlling phone operations using electronic devices are generally cumbersome and inefficient. For example, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes on multiple devices. Some existing techniques require specific interactions with specific devices even (e.g., headset and phone) when the multiple devices are otherwise capable of communication with one another. Some existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices.

[0004] Accordingly, the present technique provides electronic devices with faster, more efficient methods and interfaces for managing phone operations. Such methods and interfaces optionally complement or replace other methods for managing phone operations. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges.

[0005] In some embodiments, a method of providing phone functionalities comprises: at an electronic device with a touch-sensitive display, wherein the touch-sensitive display comprises one or more sensors to detect the intensity of touches on the touch-sensitive display: during an active phone call, detecting a touch on the touch-sensitive display, wherein the touch has a characteristic intensity and is located at the position of a first affordance; determining whether the characteristic intensity exceeds a predetermined threshold intensity; in response to at least a determination that the characteristic intensity exceeds the predetermined threshold intensity, sending an instruction to a cellular phone instructing the cellular phone to display a second affordance, wherein the second affordance, when selected, causes the cellular phone to retrieve the active phone call; and in response to at least a determination that the characteristic intensity is below the predetermined threshold intensity, performing a function associated with the first affordance.

[0006] Executable instructions for performing these functions are, optionally, included in a non-transitory computer-readable storage medium or other computer program product configured for execution by one or more processors. Executable instructions for performing these functions are, optionally, included in a transitory computer-readable storage medium or other computer program product configured for execution by one or more processors.

[0007] In some embodiments, a non-transitory computer readable storage medium stores one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of an electronic device with a display, cause the device to: during an active phone call, detect a touch on the display, wherein the touch has a characteristic intensity and is located at the position of a first affordance; determine whether the characteristic intensity exceeds a predetermined threshold intensity; in response to at least a determination that the characteristic intensity exceeds the predetermined threshold intensity, send an instruction to a cellular phone instructing the cellular phone to display a second affordance, wherein the second affordance, when selected, causes the cellular phone to retrieve the active phone call; and in response to at least a determination that the characteristic intensity is below the predetermined threshold intensity, perform a function associated with the first affordance.

[0008] In some embodiments, an electronic device, comprises: a display, one or more processors; a memory; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for: during an active phone call, detecting a touch on the display, wherein the touch has a characteristic intensity and is located at the position of a first affordance; determining whether the characteristic intensity exceeds a predetermined threshold intensity; in response to at least a determination that the characteristic intensity exceeds the predetermined threshold intensity, sending an instruction to a cellular phone instructing the cellular phone to display a second affordance, wherein the second affordance, when selected, causes the cellular phone to retrieve the active phone call; and in response to at least a determination that the characteristic intensity is below the predetermined threshold intensity, performing a function associated with the first affordance.

[0009] Thus, devices are provided with faster, more efficient methods and interfaces for managing phone operations, thereby increasing the effectiveness, efficiency, and user satisfaction with such devices. Such methods and interfaces may complement or replace other methods for managing phone operations.

[0040] The following description sets forth exemplary methods, parameters and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.

[0041] It is desirable for a user who is in the proximity of multiple electronic devices to be able to efficiently control how phone call operations are to be handled by not just one but one or more of those devices. For example, a user may have a cellular phone in his pocket, a wearable headset worn on his head, and a wearable multi-function device worn on his arm. When a phone call is received by the cellular phone (in his pocket), it may be more convenient for the user to (i) answer the call using a user interface on the wearable device but (ii) physically participate in the call through the worn headset, while (iii) the cellular phone remains in his pocket. Thus, a versatile user interface that provides a user efficient with control over aspects of phone call operations occurring on one or across multiple devices is desirable.

[0042] Below, FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5B, provide a description of exemplary devices that may participate in the handling of a phone. FIGS. 6A-6H, 7A-7E, 8A-8E, 9A-9B, 10A-10C, and 11A-11C illustrate exemplary user interfaces for controlling aspects of phone operations. The user interfaces in the figures are also used to illustrate the processes described below, including the processes in FIGS. 12-15.

[0043] Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch.

[0044] The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0045] The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

[0046] Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad).

[0047] In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick.

[0048] The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

[0049] The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

[0050] Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device 100 includes memory 102 (which optionally includes one or more computer-readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more contact intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

[0051] As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

[0052] As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

[0053] It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits.

[0054] Memory 102 optionally includes one or more computer-readable storage mediums. The computer-readable storage mediums are optionally tangible and non-transitory. The computer-readable storage mediums are optionally transitory. Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller 122 optionally controls access to memory 102 by other components of device 100.

[0055] Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data. In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

[0056] RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry 108 optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

[0057] Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

[0058] I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input control devices 116. The other input control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

[0059] A quick press of the push button optionally disengages a lock of touch screen 112 or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g., 206) optionally turns power to device 100 on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

[0060] Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects.

[0061] Touch screen 112 has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

[0062] Touch screen 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif.

[0063] A touch-sensitive display in some embodiments of touch screen 112 is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. patents: U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen 112 displays visual output from device 100, whereas touch-sensitive touchpads do not provide visual output.

[0064] A touch-sensitive display in some embodiments of touch screen 112 is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

[0065] Touch screen 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

[0066] In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

[0067] Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

[0068] Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 is used along with the touch screen display for both video conferencing and still and/or video image acquisition.

[0069] Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

[0070] Device 100 optionally also includes one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 is, optionally, coupled to input controller 160 in I/O subsystem 106. Proximity sensor 166 optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

[0071] Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112, which is located on the front of device 100.

[0072] Device 100 optionally also includes one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled to an input controller 160 in I/O subsystem 106. Accelerometer 168 optionally performs as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

[0073] In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

[0074] Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

[0075] Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices.

[0076] Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

[0077] In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

[0078] Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event.

[0079] Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

[0080] In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

[0081] Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

[0082] Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

[0083] GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing; to camera 143 as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

In some embodiments, transmitted and/or received instant messages optionally include graphics, photos, audio files, video files and/or other attachments as are supported in an MMS and/or an Enhanced Messaging Service (EMS). As used herein, “instant messaging” refers to both telephony-based messages (e.g., messages sent using SMS or MMS) and Internet-based messages (e.g., messages sent using XMPP, SIMPLE, or IMPS).

[0110] In conjunction with RF circuitry 108, touch screen 112, display controller 156, contact/motion module 130, graphics module 132, text input module 134, GPS module 135, map module 154, and music player module, workout support module 142 includes executable instructions to create workouts (e.g., with time, distance, and/or calorie burning goals); communicate with workout sensors (sports devices); receive workout sensor data; calibrate sensors used to monitor a workout; select and play music for a workout; and display, store, and transmit workout data.

[0121] In conjunction with touch screen 112, display controller 156, contact/motion module 130, graphics module 132, audio circuitry 110, speaker 111, RF circuitry 108, text input module 134, e-mail client module 140, and browser module 147, online video module 155 includes instructions that allow the user to access, browse, receive (e.g., by streaming and/or download), play back (e.g., on the touch screen or on an external, connected display via external port 124), send an e-mail with a link to a particular online video, and otherwise manage online videos in one or more file formats, such as H.264. In some embodiments, instant messaging module 141, rather than e-mail client module 140, is used to send a link to a particular online video. Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety.

[0122] Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module 152, FIG. 1A). In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

[0123] In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

[0124] The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

[0125] FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

[0126] Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

[0127] In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

[0128] Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

[0129] In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripherals interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

[0130] In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

[0131] Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

[0132] Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

[0133] Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module 172, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

[0134] Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

[0135] Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver 182.

[0136] In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

[0137] In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177, or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 include one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

[0138] A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170 and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

[0139] Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

[0140] Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event (187) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

[0141] In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

[0142] In some embodiments, the definition for a respective event (187) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

[0143] When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

[0144] In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

[0145] In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

[0146] In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

[0147] In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

[0148] In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

[0149] It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

[0150] FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

[0151] Device 100 optionally also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally, executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

[0152] In some embodiments, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, subscriber identity module (SIM) card slot 210, headset jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

[0153] FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPUs) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

[0154] Each of the above-identified elements in FIG. 3 are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

[0155] Attention is now directed towards embodiments of user interfaces that is, optionally, implemented on, for example, portable multifunction device 100.

[0156] FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

• • [0157] Signal strength indicator(s) 402 for wireless communication(s), such as cellular and Wi-Fi signals;
  • [0158] Time 404;
  • [0159] Bluetooth indicator 405;
  • [0160] Battery status indicator 406;
  • [0161] Tray 408 with icons for frequently used applications, such as:
    • [0162] Icon 416 for telephone module 138, labeled “Phone,” which optionally includes an indicator 414 of the number of missed calls or voicemail messages;
    • [0163] Icon 418 for e-mail client module 140, labeled “Mail,” which optionally includes an indicator 410 of the number of unread e-mails;
    • [0164] Icon 420 for browser module 147, labeled “Browser;” and
    • [0165] Icon 422 for video and music player module 152, also referred to as iPod (trademark of Apple Inc.) module 152, labeled “iPod;” and
  • [0166] Icons for other applications, such as:
    • [0167] Icon 424 for IM module 141, labeled “Messages;”
    • [0168] Icon 426 for calendar module 148, labeled “Calendar;”
    • [0169] Icon 428 for image management module 144, labeled “Photos;”
    • [0170] Icon 430 for camera module 143, labeled “Camera;”
    • [0171] Icon 432 for online video module 155, labeled “Online Video;”
    • [0172] Icon 434 for stocks widget 149-2, labeled “Stocks;”
    • [0173] Icon 436 for map module 154, labeled “Maps;”
    • [0174] Icon 438 for weather widget 149-1, labeled “Weather;”
    • [0175] Icon 440 for alarm clock widget 149-4, labeled “Clock;”
    • [0176] Icon 442 for workout support module 142, labeled “Workout Support;”
    • [0177] Icon 444 for notes module 153, labeled “Notes;” and
    • [0178] Icon 446 for a settings application or module, labeled “Settings,” which provides access to settings for device 100 and its various applications 136.

[0179] It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 are labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

[0180] FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 359) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 357 for generating tactile outputs for a user of device 300.

[0181] Although some of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

[0182] Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

[0183] FIG. 5A illustrates exemplary personal electronic device 500. Device 500 includes body 502. In some embodiments, device 500 can include some or all of the features described with respect to devices 100 and 300 (e.g., FIGS. 1A-4B). In some embodiments, device 500 has touch-sensitive display screen 504, hereafter touch screen 504. Alternatively, or in addition to touch screen 504, device 500 has a display and a touch-sensitive surface. As with devices 100 and 300, in some embodiments, touch screen 504 (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen 504 (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device 500 can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device 500.

[0184] Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, each of which is hereby incorporated by reference in their entirety.

[0185] In some embodiments, device 500 has one or more input mechanisms 506 and 508. Input mechanisms 506 and 508, if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device 500 has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device 500 with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device 500 to be worn by a user.

[0186] FIG. 5B depicts exemplary personal electronic device 500. In some embodiments, device 500 can include some or all of the components described with respect to FIGS. 1A, 1B, and 3. Device 500 has bus 512 that operatively couples I/O section 514 with one or more computer processors 516 and memory 518. I/O section 514 can be connected to display 504, which can have touch-sensitive component 522 and, optionally, intensity sensor 524 (e.g., contact intensity sensor). In addition, I/O section 514 can be connected with communication unit 530 for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device 500 can include input mechanisms 506 and/or 508. Input mechanism 506 is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism 508 is, optionally, a button, in some examples.

[0187] Input mechanism 508 is, optionally, a microphone, in some examples. Personal electronic device 500 optionally includes various sensors, such as GPS sensor 532, accelerometer 534, directional sensor 540 (e.g., compass), gyroscope 536, motion sensor 538, and/or a combination thereof, all of which can be operatively connected to I/O section 514.

[0188] Memory 518 of personal electronic device 500 can be a non-transitory computer-readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors 516, for example, can cause the computer processors to perform the techniques described above, including processes 1200-1500, 2100, and 2400 (FIGS. 12-15, 21, and 24). The computer-executable instructions can also be stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory computer-readable storage medium” can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device 500 is not limited to the components and configuration of FIG. 5B, but can include other or additional components in multiple configurations.

[0189] As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices 100, 300, and/or 500 (FIGS. 1, 3, and 5). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance.

[0190] As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112 in FIG. 4A) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

[0191] As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

[0192] FIG. 5C illustrates detecting a plurality of contacts 552A-552E on touch-sensitive display screen 504 with a plurality of intensity sensors 524A-524D. FIG. 5C additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors 524A-524D relative to units of intensity. In this example, the intensity measurements of intensity sensors 524A and 524D are each 9 units of intensity, and the intensity measurements of intensity sensors 524B and 524C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors 524A-524D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity. FIG. 5D illustrates assigning the aggregate intensity to contacts 552A-552E based on their distance from the center of force 554. In this example, each of contacts 552A, 552B and 552E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts 552C and 552D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A. (Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to FIGS. 5C-5D can be performed using an electronic device similar or identical to device 100, 300, or 500. In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in FIGS. 5C-5D to aid the reader.

[0193] In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

[0194] The intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

[0195] An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero.

[0196] In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

[0197] FIGS. 5E-5H illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact 562 from an intensity below a light press intensity threshold (e.g., “IT_L”) in FIG. 5E, to an intensity above a deep press intensity threshold (e.g., “IT_D”) in FIG. 5H. The gesture performed with contact 562 is detected on touch-sensitive surface 560 while cursor 576 is displayed over application icon 572B corresponding to App 2, on a displayed user interface 570 that includes application icons 572A-572D displayed in predefined region 574. In some embodiments, the gesture is detected on touch-sensitive display 504. The intensity sensors detect the intensity of contacts on touch-sensitive surface 560. The device determines that the intensity of contact 562 peaked above the deep press intensity threshold (e.g., “IT_D”). Contact 562 is maintained on touch-sensitive surface 560. In response to the detection of the gesture, and in accordance with contact 562 having an intensity that goes above the deep press intensity threshold (e.g., “IT_D”) during the gesture, reduced-scale representations 578A-578C (e.g., thumbnails) of recently opened documents for App 2 are displayed, as shown in FIGS. 5F-5H. In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact 562 is not part of a displayed user interface, but is included in FIGS. 5E-5H to aid the reader.

[0198] In some embodiments, the display of representations 578A-578C includes an animation. For example, representation 578A is initially displayed in proximity of application icon 572B, as shown in FIG. 5F. As the animation proceeds, representation 578A moves upward and representation 578B is displayed in proximity of application icon 572B, as shown in FIG. 5G. Then representations 578A moves upward, 578B moves upward toward representation 578A, and representation 578C is displayed in proximity of application icon 572B, as shown in FIG. 5H. Representations 578A-578C form an array above icon 572B. In some embodiments, the animation progresses in accordance with an intensity of contact 562, as shown in FIGS. 5F-5G, where the representations 578A-578C appear and move upwards as the intensity of contact 562 increases toward the deep press intensity threshold (e.g., “IT_D”). In some embodiments the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to FIGS. 5E-5H can be performed using an electronic device similar or identical to device 100, 300, or 500.

[0199] In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

[0200] For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

[0201] As used herein, an “installed application” refers to a software application that has been downloaded onto an electronic device (e.g., devices 100, 300, and/or 500) and is ready to be launched (e.g., become opened) on the device. In some embodiments, a downloaded application becomes an installed application by way of an installation program that extracts program portions from a downloaded package and integrates the extracted portions with the operating system of the computer system.

[0202] As used herein, the term “open application” or “executing application” refers to a software application with retained state information (e.g., as part of device/global internal state 157 and/or application internal state 192). An open or executing application may be any one of the following types of applications:

• • [0203] an active application, which is currently displayed on a display screen of the device that the application is being used on;
  • [0204] a background application (or background processes) which is not currently displayed, but one or more processes for the application are being processed by one or more processors; and
  • [0205] a suspended or hibernated application, which is not running, but has state information that is stored in memory (volatile and non-volatile, respectively) and that can be used to resume execution of the application.

[0206] As used herein, the term “closed application” refers to software applications without retained state information (e.g., state information for closed applications is not stored in a memory of the device). Accordingly, closing an application includes stopping and/or removing application processes for the application and removing state information for the application from the memory of the device. Generally, opening a second application while in a first application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application.

[0207] Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device 100, device 300, or device 500 (FIGS. 1A, 3A, and/or 5A), to provide phone functionalities.

[0208] FIG. 6A illustrates exemplary wearable electronic device 600. Wearable electronic device 600 is device 500 (FIG. 5A) in some embodiments. As shown, device 600 is displaying user interface screen 602. User interface screen 602 in some embodiments has icons for launching features on device 600, including icon 604 for launching a phone user interface. In response to a user selection (e.g., touch) of icon 605, device 600 displays exemplary phone user interface screen 610. Screen 610 is referred to as a landing screen, as it is the user interface screen that is displayed when phone features are initially launched on device 600.

[0209] Landing screen 610, displayed in some embodiments, has status indicator 611 indicating whether a cellular phone and/or a headset are operatively connected for use for phone calls. Landing screen 610 also has affordance 612, which, when selected, displays a list of contacts that have been designated by a user to be favorite contacts. Landing screen 610 also has affordance 613, which, when selected, displays a list of recent incoming and/or outgoing calls. Landing screen 610 also has affordance 614, which, when selected, displays a list of address book contacts accessible to device 600. Landing screen 610 also has affordance 615, which, when selected, displays a listing of voicemail messages that have been left for the user.

[0210] Optionally, affordance 613 has missed-call indicator 616 indicating the number of missed calls. Optionally, affordance 615 has new voicemail indicator 618 indicating the number of new voicemail messages. Optional indicators 616 and/or 618 may be hidden from view when there is no missed call or new voicemail message. Landing screen 610 is scrollable to reveal additional content such as affordances for accessing additional phone features. In some embodiments, landing screen 610 is scrolled via touch input. In some embodiments, landing screen 610 is scrolled in response to movement of a rotatable input mechanism of device 600.

[0211] FIG. 6B illustrates an exemplary user-designated favorites screen 620 that is displayed in some embodiments in response to a user selection of affordance 612 (FIG. 6A). Favorites screen 620 has one or more affordances (e.g., 622-625) identifying user-designated contacts. A call may be placed by selecting one of affordances 622-625. An affordance representing a user-designated contact may optionally include an information icon 621 for accessing additional information regarding the contact on a user interface screen referred to as a contact card. A contract card provides contact information such as contact name, phone number and/or addresses (optionally shown on a map). A contact card may also have affordances for initiating communication with contact, such as by audio and/or video call, as well as via messages (e.g., short messages via services such as SMS and MMS, text messages via services such as iMessage® provided by Apple, Inc. of Cupertino, Calif., e-mail messages). User-designated favorites screen 620 is scrollable to reveal additional affordances representing user-designated contacts. In some embodiments, favorites screen 620 is scrolled via touch input. In some embodiments, favorites screen 620 is scrolled in response to movement of a rotatable input mechanism of device 600.

[0212] FIG. 6C illustrates exemplary recent calls screen 630, which is displayed in some embodiments in response to a user selection of affordance 613 (FIG. 6A). Recent calls screen 630 has affordances indicating recent incoming and/or outgoing calls, such as affordance 632-635. Affordances representing recent calls may include additional information about the call—such as the identity of the call's participant(s), a phone number or other identifier associated with the call, the duration of the call, the time of the call, so forth. A user may select a displayed affordance to call the represented participant(s). An affordance representing a recent call may optionally include an information icon for accessing additional information regarding the represented contact, e.g., by displaying a corresponding contact card. Recent calls screen 630 is scrollable to reveal additional affordances representing recent calls. In some embodiments, recent calls screen 630 is scrolled via touch input. In some embodiments, recent calls screen 630 is scrolled in response to movement of a rotatable input mechanism of device 600.

[0213] FIG. 6D illustrates exemplary contacts screen 640, which is displayed in some embodiments in response to a user selection of affordance 614 (FIG. 6A). Contacts screen 640 has affordances representing contacts that are accessible to device 600, such as contact affordances 642-645. A user may select a displayed affordance to initiate a call to the represented contact. An affordance representing a contact may optionally include an information icon for accessing additional information regarding the represented contact, e.g., by displaying a corresponding contact card. Contacts screen 640 is scrollable to reveal additional affordances representing user-designated contacts. In some embodiments, contacts screen 640 is scrolled via touch input. In some embodiments, contacts screen 640 is scrolled in response to movement of a rotatable input mechanism of device 600. In some embodiments, contacts screen 621 has index indicator 641 for scrolling through contact affordances.

[0214] FIG. 6E illustrates exemplary voicemail screen 650, which is displayed in some embodiments in response to a user selection of affordance 615 (FIG. 6A). Voicemail screen 650 has affordances representing voicemail messages that are accessible using device 600, such as affordances 652-655. An affordance representing a voicemail may optionally include information about the voicemail message such as the caller, the duration of the message, the time of the message, an indication of whether the message has been played, so forth.

[0215] FIG. 6F illustrates exemplary in-call screen 660, which is displayed in some embodiments when a call is in-progress. As shown, in-call screen 660 includes volume control 662, as well as affordance 664 and 668 for accessing call functions. Exemplary call functions include holding the call, ending the call, muting the call, accessing a keypad, and so forth. In-call screen 660 also displays the identity of other call participant(s). In-call screen 660 is responsive to user navigation input. For example, during a call, a user may activate (e.g., touch or a rotate) one of the input mechanisms of device 600 to navigate away from in-call screen 660. When a user navigates away from in-call screen 660 while remaining on a call, device 600 in some embodiments displays an indicator of the in-progress phone call so that the user is aware that the call remains in-progress. This aspect is discussed with reference to FIG. 6G.

[0216] FIG. 6G illustrates exemplary user interface screen 670, displayed in response to user navigation away from in-call screen 652 while continuing with a call, in some embodiments. For example, a user may activate (e.g., touch or a rotate) one of the input mechanisms of device 600 while in-call screen 660 is displayed to access another user interface screen on device 600, such as a screen provided by another application. User interface screen 670 may be any user interface screen provided by device 600. In the illustrated example, user interface screen 670 is a modified instance of landing screen 610. In particular, screen 670 includes in-call indicator 676 indicating the status of the in-progress call. In-call indicator 678 includes call participant identifier 677 and a call duration indicator 678. In-call indicator 678 is displayed for the duration of the call (or until the user returns to in-call screen 660). In-call indicator 676 is positioned towards the top of landing screen 670 so as to increase its visibility to a user. The remaining contents of screen 670 are displayed below in-call indicator 676. As shown, voicemail affordance 675 is partially off-screen due to the inclusion of in-call indicator 676. By displaying in-call indicator 686, device 600 provides a user who has navigated away from in-call screen 660 an efficient method of returning to in-call screen 660 for accessing call-related features. As will be understood, in-call indicator 676 or 686 can be displayed on any user interface screen of the device while a call is in progress in response to user navigation away from in-call screen 652.

[0217] FIG. 6G also illustrates exemplary user interface 680 which is a variation of screen 670, displayed in some embodiments under certain usage conditions. In addition to affordances 683-685 for accessing phone features, as well as in-call indicator 686 indicating that a call is in-progress, screen 680 includes an additional application-specific persistent indicator 687. In the illustrated example, application-specific indicator 687 is a music playback indicator showing the current status of a background music player application. Notably, although both indicators 686 and 687 are “persistent” in the sense that they remain displayed to indicate an ongoing process (ceasing to be displayed when the application associated with the process becomes actively displayed), the indicators are still able to accommodate for the presence of one another. In the example of FIG. 6G, in-call indicator 686 moved down-screen in order to accommodate music playback indicator 687.

[0218] FIG. 6H illustrates exemplary call-waiting screen 690, displayed in some embodiments when an incoming call (e.g., a second call) is received while a first call is in-progress. As shown, call-waiting screen 690 has incoming call identifier 694 identifying the incoming call, affordance text 692 identifying the first call, affordance 696 for answering the second call, and affordance 698 for ignoring the second call. Although not shown, call-waiting screen 690 may have affordances representing additional ways of handling the multiple calls. For example, an affordance can be displayed permitting a user to hang up the first call and answer the second call with a single activation of the affordance.

[0219] Attention is now directed to how one or more of the above-described user interface screens may be used in handling incoming and outgoing calls, particularly in scenarios where multiple devices that are capable of participating in a call are proximate (e.g., within wireless communication range of one another). Exemplary scenarios are described below with reference to FIGS. 7-9. Before turning to the illustrative examples, however, a brief summary of exemplary connection scenarios, and guiding operation principles, is provided in table 1, below. Consider the scenario in which a cellular phone, a wearable electronic device, and a headset are within communication range of one another:

[0220] Turning first to FIGS. 7A-7D, FIG. 7A illustrates an exemplary scenario (1) in which user 700 is in possession of cellular phone 702, wearable electronic device 704, and headset 706. Cellular phone 702 is device 100 (FIG. 1A) in some embodiments. Wearable electronic device 704 is device 500 (FIG. 5A). Headset 706 is a wireless (e.g., Bluetooth-enabled) headset in the illustration but may also be a microphone-equipped, earpiece, headphone, or the like, whether wired or wireless.

[0221] Devices 702, 704, 706 are configured to communicate with one another. In some embodiments, operative communication between two devices results from a two-stage process. First, the devices become paired. As used herein, two devices are “paired” if they are registered to communicate with one another. An exemplary pairing process is the Bluetooth pairing process. Another exemplary pairing process is the registration of a WiFi profile for purposes of communicating with another WiFi-enabled device (e.g., an access point or equivalent). Other pairing processes are possible. For example, two devices may each become registered with a cloud-based user identifier, such as an AppleID® provided by Apple, Inc. of Cupertino, Calif. Second, the paired devices share an operative connection. Two paired devices may operatively connect with one another when they come within range of one another. They may rely on information obtained during the pairing process, such as the use of an authentication token, in order to create an operative connection. One situation in which two nearby, paired devices are not operatively connected arise when one device is powered-off or in airplane mode.

[0222] In some embodiments actual operative communication can result from an ad hoc connection. Although pairing is sometimes a pre-requisite to establishing communication, (such as under communication protocols like Bluetooth), a lack of pairing in these embodiments do not necessarily preclude two devices from forming an ad hoc communication session, thereby becoming operatively connected, in certain embodiments.

[0223] In the illustrated scenario of FIG. 7A, wearable electronic device 704 is paired with and operatively connected to cellular phone 702; headset 706 is paired with and operatively connected to cellular phone 702. Cellular phone 702 has cellular circuitry necessary for placing and receiving a (cellular) phone call.

[0224] Attention is now directed to how a call may be initiated in this exemplary scenario. Recall from table 1 that in this scenario it is desirable to place the call while requiring little to no user interaction with cellular phone 702. Turning to FIG. 7B, wearable electronic device 704 displays phone affordance 712 for accessing phone functions. Wearable electronic device 704 may, along with affordance 712, display indication 714 of status of connection(s) between devices 702, 704, and/or 706. As shown, status indicator 714 indicates (textually) an operative connection between the wearable electronic device 704 and cellular phone 702, as well as (symbolically via an image) an operative connection between cellular phone 702 and headset 706.

[0225] While phone affordance 712 is displayed, a user may select the affordance to access phone landing screen 720. Phone landing screen 720 is screen 610 (FIG. 6A) in some embodiments. A user may select favorite contacts affordance 722 via touch 724 to display phone contacts on screen 726, which is user-designated favorites screen 620 (FIG. 6B) in some embodiments. The listing of contacts includes contact affordance 728 representing “Contact Z.” The user may select contact affordance 728 via touch 730 to initiate a call to the represented contact.

[0226] To initiate the call, wearable electronic device 704 sends instructions to cellular phone 702 instructing cellular phone 702 to place a call to Contact Z. Upon initiating the call, wearable electronic device 704 displays in-call screen 732 and cellular phone 702 displays calling screen 736. Continuing onto FIG. 7C, after the call has been made (e.g., after a predetermined time or after the call is answered), wearable electronic device 704 displays in-call screen 740, which is in-call screen 660 (FIG. 6F) in some embodiments. In the meantime, cellular phone 702 transitions to displaying exemplary in-call screen 742 which includes an identification for the call and affordance(s) for phone operations such as ending the call. Further, as cellular phone 702 is operatively connected to headset 706, cellular phone 702 communicates with headset 706 so that the headset 706 is used to carry on the call, meaning that a microphone of headset 706 is used to provide input to the call, and a speaker of headset 706 is used to provide output from the call. As shown, in-call screen 740 includes a volume affordance for controlling the output of headset 706.

[0227] Attention is now directed to how a call may be received in this exemplary device-pairing scenario. Recall from table 1 that in this scenario (1) it is desirable to receive the call while requiring little to no direct user interaction with cellular phone 702. As shown in FIG. 7D, wearable electronic device 704 may have an inactive screen (though the device itself is turned on) while cellular phone 702 receives incoming call 748 and displays incoming call screen 746. Wearable electronic device 704 receives from cellular phone 702 an indication of the incoming call, and in response, displays incoming call screen 750. Incoming call screen 750 has identification 756 identifying the caller. Also, wearable electronic device 704 may produce an audible and/or haptic output alerting the user to the incoming call. Incoming-call screen 750 has exemplary accept affordance 752 for accepting the call and exemplary decline affordance 754 for declining the call.

[0228] If a user selects accept affordance 752 as indicated by touch 758, wearable electronic device 704 sends an indication to cellular phone 702 indicating user acceptance. Continuing onto FIG. 7E, in response to the user acceptance, cellular phone 702 answers the incoming call and uses headset 706 for carrying on the answered call. Wearable device 704 then displays in-call screen 770, which is in-call screen 660 (FIG. 6F) in some embodiments. In-call screen 770 includes a volume affordance for controlling the output of headset 706.

[0229] Although not shown, it is possible for the user to select decline affordance 754 while incoming-call screen 750 is displayed on wearable electronic device 704. When this occurs, wearable electronic device 704 sends an indication to cellular phone 706 indicating the user's refusal of the incoming call. Cellular phone 702, in turn, declines the incoming call and ceases to display incoming-call screen 730, thereby returning to the user interface screen that was displayed prior to incoming-call screen 750 (or turns off its display if no prior user interface screen was being displayed). Also, although not shown, headset 706 may be wired (or wireless).

[0230] Turning to FIGS. 8A-8E, FIG. 8A illustrates an exemplary scenario (2) in which user 800 has possession of cellular phone 802 and wearable electronic device 804, but no headset. Cellular phone 802 is device 100 (FIG. 1A) in some embodiments. Wearable electronic device 804 is device 500 (FIG. 5A) in some embodiments. In the illustrated scenario, wearable electronic device 804 is paired with and operatively connected to cellular phone 802. Cellular phone 802 is not operatively connected to a headset, even though it may be paired with one.

[0231] Attention is now directed to how a call may be initiated in this scenario. Recall from table 1 that in this scenario (2) it is desirable to permit wearable electronic device 804 to queue a call onto cellular phone 802, thereby allowing user 800 to primarily interact with wearable electronic device 804 to initiate a call, but carry on the phone call using the microphone and speaker (e.g., earphone) of cellular phone 806. (The use of cellular phone 806 in this instance avoids the use of a speakerphone on wearable electronic device 804, which may be less private.) In situations where wearable electronic device 804 is more conveniently accessible than cellular phone 806, this feature reduces the burdens placed on the user-particularly when answering an incoming call—thereby improving the overall user experience.

[0232] As shown in FIG. 8B, wearable electronic device 804 displays phone affordance 812 for accessing phone functions. Wearable electronic device 804 may determine that wearable electronic device 804 is operatively connected to cellular phone 802, but cellular phone 802 is not operatively connected to a headset. Wearable electronic device 804 may display, along with affordance 812, indications of these connection statuses. As shown, affordance. 812 has indication 813 which textually indicates that wearable electronic device 804 is operatively connected to cellular phone 802, and symbolically indicates that cellular phone 802 is not operatively connected to a headset.

[0233] As shown, a user may select affordance 812 to access phone landing screen 814. Phone landing screen 814 is screen 610 (FIG. 6A) in some embodiments. A user may select user-designated favorites affordance 816 to retrieve a listing of phone contacts on user-designated favorites screen 820, via touch 818. Screen 820 includes affordance 822 representing “Contact Z.” The user may select contact affordance 820 to initiate a call to the represented contact (e.g., Contact A), via touch 824.

[0234] To initiate the call, wearable electronic device 804 sends instructions to cellular phone 802 instructing cellular phone 802 to initiate a call to Contact Z. Instead of placing the call immediately, however, cellular phone 802 displays call-queuing screen 832. Call-queuing screen 832 indicates that cellular phone 802 is ready to place a call, but that an additional user input is required. In the illustrated example the required user input is a swipe input, as indicated by instruction text 837, though other inputs such as a touch or activation of a button may be used. In the meantime, wearable electronic device 804 displays call-queuing screen 830 to indicate that the call to Contact Z is being queued on cellular phone 802.

[0235] Continuing to FIG. 8C, when cellular phone 802 receives swipe input 838, it places the call to Contact Z and displays calling screen 842. Cellular phone 802 may also send data to wearable electronic device 804 indicating that the call has been placed. In response, wearable electronic device 804 displays calling screen 842. Calling screen 840 includes affordance 844 for ending the call and volume affordance 846 for controlling a volume of the speaker of cellular phone 802, which is being used for carrying on the call, as there is no connected headset.

[0236] In the above-described technique, cellular phone 802 queues up a requested call instead of calling immediately so as to provide user 800 an opportunity to retrieve cellular phone 802 from a nearby location (e.g., pocket, table). Because the phone call, once placed, would utilize the speaker and microphone of cellular phone 802, it is beneficial to allow user 800 an opportunity to gain physical control of cellular phone 802 before initiating the call.

[0237] Attention is now directed to how a call may be received in this exemplary device-pairing scenario. As shown in FIG. 8D, wearable electronic device 804 may be inactive (though powered-on) when cellular phone 802 receives an incoming call. Wearable electronic device 804 may receive from cellular phone 802 an indication of the incoming call, and in response, display in-coming call screen 852. Wearable electronic device 804 may also produce an audible and/or haptic output alerting user 800 to the incoming call. Incoming-call screen 852 has affordance 854 for accepting the call and affordance 856 for declining the call.

[0238] In response to a user selection of affordance 854 (e.g., via touch 858), wearable electronic device 804 sends an indication to cellular phone 802 indicating user acceptance of the call. Instead of enabling the speaker and microphone of cellular phone 802 immediately, however, cellular phone 802 holds call and displays call-holding screen 880 to indicate that the incoming call has been held. Call-holding screen 880 indicates in region 881 that the call will be un-held if a user provides a swipe input. In the meantime, wearable electronic device 804 displays call-holding screen 870 to indicate that the incoming call has been held.

[0239] Continuing to FIG. 8E, in response to swipe input 884 on slide-to-connect affordance 862, cellular phone 804 un-holds the call and displays in-call screen 890. Once un-held, cellular phone 802 enables its microphone and speaker so user 800 may participate in the call. Cellular phone 802 also sends data to wearable electronic 804 indicating that the call has been un-held. In response, wearable electronic device 804 replaces the display of call-holding screen 870 with in-call screen 884. In-call screen 884 is screen 660 (FIG. 6F) in some embodiments.

[0240] Returning to call-holding screen 870, while call-holding screen 870 is displayed by wearable electronic device 804, a user may select end-call affordance 872 to hang-up the incoming phone call that has been held. Optionally, while the call is being held, an audio message is played to the caller informing the caller that the phone call is being held. The message may also ask the caller to hold the line so as to permit user 800 an opportunity to participate verbally in the call.

[0241] Turning to FIG. 9A-9B, FIG. 9A illustrate an exemplary scenario (3) in which user 900 has in his possession wearable electronic device 904 and headset 906, but not cellular phone 902. Wearable electronic device 904 is device 500 (FIG. 5A) in some embodiments. Cellular phone 902 may be unavailable because it is out of range.

[0242] Recall from table 1 that in this scenario it is still preferable for wearable electronic device 904 to provide some phone-related functionalities. For instance, wearable electronic device 904 may permit the retrieval of voicemail messages. This aspect is discussed with respect to FIG. 9B. As shown in FIG. 9B, wearable electronic device 904 displays user interface screen 910 having phone affordance 912. Phone affordance 912 may include indication 914 of the wearable electronic device's communication status with cellular phone 902 and headset 906. In response to a selection of phone affordance 912, wearable electronic device 904 displays phone landing screen 920. Landing screen 920 is landing screen 610 (FIG. 6A), or a modified instance thereof, in some embodiments. For instance, landing screen 910 may have a reduced number of affordances as compared with landing screen 610, excluding an affordance for accessing phone contacts that may be stored on cellular phone 902, for example.

[0243] In the illustrated example, landing screen 910 includes voicemail affordance 922 for accessing voicemail even when wearable electronic device 904 is not operatively connected to a cellular phone. In response to a user selection of voicemail affordance 922 via touch 924, wearable electronic device 904 displays voicemail screen 930. Voicemail screen 930 may have affordances representing voicemail messages, including affordance 932. In response to a user selection of voicemail affordance 932, wearable electronic device 904 displays voicemail playback screen 940, which indicates the voicemail message being played, and has affordances for accessing the voicemail message, such as affordance 942 to play the message and affordance 944 to delete the message. In response to a selection of playback affordance 942, wearable electronic device 902 initiates playback of the message on headset 906, meaning that the audio portion of the voicemail message is played on a speaker of headset 906. In some embodiments, when headset 906 is not operatively connected to wearable electronic device 902 (not shown), wearable electronic device 902 may playback the voicemail message on its internal speaker.

[0244] Wearable electronic device 904 also may be able to perform other phone-related functions. In some embodiments, wearable electronic device 904 can display recent calls. In some embodiments, wearable electronic device 904 can display notification regarding missed calls, which may be received via a communication (e.g., WiFi) unit of device 904.

[0245] When a wearable electronic device is operatively connected to a cellular phone and the cellular phone is in turn operatively connected to a headset, a user may find it useful under some circumstances to carry on a phone call using the headset, and at other times, using the internal speaker and microphone of the cellular phone. Attention is now directed to user interfaces for making this transition, with reference to FIGS. 10A-10C and 11A-11C.

[0246] In some embodiments, user interfaces for transitioning between headset and cellular phone usage are responsive to the touch intensity of user input. Because wearable electronic devices are compact in design, they tend to have small surface areas for the configuration of touch-sensitive and/or mechanical input mechanisms (e.g., buttons). The addition of a touch-intensity based input modality is helpful in that it permits additional user interaction techniques to be incorporated while preserving the overall form factor of the device. This aspect is discussed with reference to FIGS. 10A-10C.

[0247] FIG. 10A depicts wearable electronic device 1000 which is device 500 (FIG. 5A) in some embodiments. As shown, wearable electronic device 1000 has determined that a phone call is in-progress. In this example, the cellular communications of the phone call are being handled by a companion cellular phone 1040, while the input to and output from the phone call are handled by a headset that is operatively connected to cellular phone 1040.

[0248] Wearable electronic device 1000 is displaying music playback screen 1002. Music playback screen 1002 is displayed in some embodiments in response to a user's selection of the music application during the phone call. Music screen 1000 includes in-call indicator 1004 indicative of the in-progress call. In-call indicator 1004 is responsive to user input, such as touch 1006, in that in-call indicator 1004, when selected, causes device 1000 to display in-call screen 1010. In-call screen has affordance 1012 for placing the in-progress phone call on hold, and affordance 1014 for ending the call. A user may access additional phone-related features through a high-intensity touch 1016 on device 1000. In the illustrated example, high-intensity touch 1016 is received at a position of affordance 1012.

[0249] Continuing to FIG. 10B, because the touch is of high intensity (e.g., high characteristic intensity), instead of carrying out a feature corresponding to affordance 1012, device 1000 displays exemplary user interface screen 1020, which has affordances for accessing additional phone-related features (if touch 1016 is of a low intensity, device 1000 carries out the feature associated with affordance 1012 instead, e.g., holding the call).

[0250] Secondary features screen 1020 includes affordance 1024 for transferring the in-progress call to a cellular phone, meaning to use the internal speaker and microphone of the cellular phone to carry on the call, instead of the headset. Screen 1020 also includes affordance 1028 for configuring device pairings. For example, a user can select affordance 1028 to pair additional headsets. Screen 1020 may also include additional affordance(s) (e.g., 1026) for invoking other functions, such as for displaying a telephone keypad for navigating an interactive voice response system.

[0251] In response to user selection 1022 of affordance 1024, device 1000 sends an instruction to cellular phone 1040 instructing cellular phone 1040 to take over the phone call from the headset. In response, cellular phone 1040 places the call on hold and displays call-holding screen 1040. In the meantime, wearable electronic device 1000 also transitions to call-holding screen 1030. Call-holding screen 1050 on cellular phone 1040 includes label 1022 informing the user the call may be retrieved via user input, e.g., a swipe input. Call-holding screen 1030 on wearable electronic device 1000 includes affordance 1032 for un-holding and continuing with the call using the headset as before. Restated, the user may “pull back” the call even after selecting affordance 1024 to pass the call the cellular phone 1040.

[0252] Although not illustrated, in some embodiments, in response to user input 1022, cellular phone 1040 does not place in-progress call on hold; rather, the call continues via the headset while cellular phone 1040 awaits user input (e.g., a swipe input). When the swipe input is detected, cellular phone 1040 switches to its microphone and speaker (and disables those on the headset) to that the user may continue the phone call on cellular phone 1040. In these embodiments, it is also not necessary for wearable electronic device to display on-hold screen 1030. Instead, wearable electronic device may transition from secondary functions screen 1020 to in-call screen 1010 while the in-progress call is transitioned from the headset over to the internal microphone and speaker of cellular phone 1040.

[0253] Turning to FIG. 10C, in response to swipe input 1054, cellular phone 1040 un-holds the call, enables its speaker and microphone for purposes of participating in the call, and displays in-call screen 1040. In the meantime, wearable electronic device 1000 returns to music playback screen 1002.

[0254] Additional exemplary user interfaces for transitioning between headset and cellular phone usage are discussed with reference to FIGS. 11A-11C. As shown in FIG. 11A, cellular phone 1102 is receiving an incoming call and displays incoming-call screen 1130. Cellular phone 1102 is device 100 (FIG. 1A) in some embodiments. Wearable electronic device 1100 receives an indication of the incoming call from cellular phone 1102 and also displays incoming-call screen 1110. Wearable electronic device 1100 is device 500 (FIG. 5A) in some embodiments. Optionally, wearable electronic device 1100 may issue a haptic or audio alert informing the user of the incoming call.

[0255] Incoming-call screen includes affordance 1112 for answering call. Consistent with the discussion above regarding usage scenarios, if affordance 1112 is selected to answer the incoming call while cellular phone 1102 is operatively connected to a headset, the headset will be used for carrying on the call. A user may wish, however, to participate on the call using another device, such as by using the internal speaker and microphone of cellular phone 1102. In this situation, while incoming-call screen 1110 is displayed on wearable electronic device 1100, the user may provide swipe input 1118 to reveal affordance 1120. Affordance 1120, when selected, causes the incoming call to be placed on hold so that the user can access cellular phone 1102 to answer the call. As shown in FIG. 11A and continuing onto FIG. 11B, in response to selection 1122 of affordance 1120, the incoming call is placed on hold, and cellular phone 1102 displays on-hold screen 1140 informing the user via instruction label 1142 that the phone call can be retrieved by certain user input, in this case a swipe input. In the illustrated example, incoming call screen 1110 has affordance 1116 indicating the availability of additional features that are not displayed, such as affordance 1112 for answering the call cellular phone 1102.

[0256] The user can retrieve the call on cellular phone 1102 by swipe input 1144, which causes cellular phone 1102 to un-hold the call and enable its speaker and microphone for participation in the call. As shown, responsive to swipe input 1144, device 1150 un-holds the phone call and transitions to in-call screen 1150. In the meantime, wearable electronic device 1100 returns to user interface screen 1152, in this case a music playback screen that was displayed prior to the incoming call. Note that, while call-holding screen 1150 is displayed on wearable electronic device 1100, the user may select un-hold affordance 1152 to continue with the call as before, meaning to continue using the headset for communication. Restated, the user may “pull back” the call even after selecting affordance 1120 (FIG. 11A) to pass the call to cellular phone 1102.

[0257] In addition to affordance 1120, incoming-call screen 1110 may include affordances for accessing other phone-related features. For example, instead of verbally answering the incoming call, a user may wish to reply with a text message stating that the user is busy and cannot talk at the moment. The user may also wish to send other messages such as those containing emoji. U.S. Provisional Patent Application Ser. No. 62/044,923, entitled “USER INTERFACE FOR RECEIVING USER INPUT,” filed Sep. 2, 2014; and U.S. Provisional Patent Application Ser. No. 62/127,800, entitled “USER INTERFACE FOR RECEIVING USER INPUT,” filed Mar. 3, 2015 describe user interfaces for efficiently obtaining user input that would be helpful in the context of incoming-calls screen 1110. Each of these applications which is hereby incorporated by reference in their entirety. For example, incoming-calls screen 1110 can provide access to affordances for ignoring an incoming call and sending a suggested response, such as “can I call you back?” to the caller. As another example, incoming-calls screen 1110 can provide access to affordances for selecting and customizing an emoji to be sent to the caller. As an additional example, incoming-calls screen 1110 can provide access to an interface for transcribing a user's speech utterance into a message for the caller. As yet another example, incoming-calls screen 1110 can provide access to a reduce-sized keyboard interface for inputting a message for the caller.

[0258] In some embodiments, an incoming call may be answered or rejected using any form of user input, including a touch input and/or a swipe input. For example, as shown in FIG. 11C, cellular phone 1102 is receiving an incoming call and displays incoming-call screen 1130. Cellular phone 1102 is device 100 (FIG. 1A) in some embodiments. Wearable electronic device 1100 receives an indication of the incoming call from cellular phone 1102 and displays incoming-call screen 1160. Wearable electronic device 100 is device 500 (FIG. 5A) in some embodiments. Optionally, wearable electronic device 1100 may issue a haptic or audio alert informing the user of the incoming call.

[0259] Incoming-call screen 1160 includes visual object 1162. The visual object 1162 may be indicative of a first direction (e.g., a first horizontal direction). In response to a user input 1168 (e.g., a swipe input) anywhere on the display of the wearable electronic device in the indicated first direction (e.g., left to right), the incoming call may be answered. Incoming-call screen 1160 further includes visual object 1164 for declining the call. The visual object 1164 may be indicative of a second direction (e.g., different than the first direction) (e.g., a second horizontal direction). In response to a user input (e.g., a swipe input) anywhere on the display of the electronic device in the indicated second direction (e.g., right to left), the incoming call may be declined. In some examples, the visual object 1162 may be a first affordance, and a user may select the first affordance by dragging the first affordance in a first direction (e.g., rightward direction) to answer an incoming call. In some examples, the visual objet 1164 may be a second affordance and a user may select the second affordance by dragging the second affordance in a second direction (e.g., leftward direction) to decline the incoming call.

[0260] In some instances, a user may wish to participate on the call using another device, such as by using the internal speaker and microphone of cellular phone 1102. In this situation, while incoming-call screen 1160 is displayed on wearable electronic device 1100, the user may provide a user input (e.g., a swipe input) in a third direction (e.g., different than the first direction and/or different than the second direction) to reveal one or more affordances, such as the affordance 1120 (FIG. 11A), as described. In some examples, the incoming-call screen 1160 may include a visual object 1166 indicative of the third direction.

[0261] Consistent with the discussion above regarding usage scenarios, if the user input is provided to answer the incoming call while cellular phone 1102 is operatively connected to a headset, the headset will be used for carrying on the call.

[0262] In some embodiments, the electronic device may be incompatible with one or more types of incoming calls. Accordingly, in some instances, the electronic device can determine whether an incoming call is of a first type (e.g., calls incompatible with the electronic device including one or more types of audio calls, such as FaceTime audio calls, and/or one or more types of video calls, such as FaceTime video calls). In accordance with a determination that a call is of the first type, the electronic device displays a first affordance (e.g., affordance 1120 of FIG. 11A) that, when activated, causes the call to be placed on hold (e.g., display “answer on phone” affordance causing call to be answered and automatically placed on hold). In accordance with a determination that the incoming call is not of the first type, the electronic device displays a second affordance that, when activated, causes the incoming call to be answered (e.g., and not automatically placed on hold).

[0263] In some embodiments, in accordance with a determination that the incoming call is of the first type (e.g., the call is incompatible), the electronic device forgoes displaying the second affordance (e.g., does not display “answer on electronic device” affordance), and in accordance with a determination that the incoming call is not of the particular type, the electronic device forgoes displaying the first affordance (e.g., does not display “answer” affordance).

[0264] While displaying the first affordance, the electronic device can detect a user input activating the first affordance (e.g., the user performs a light press at a location of the hold affordance). In response to detecting the user input activating the first affordance, the electronic device displays a third affordance and a fourth affordance (e.g., the user performs a light press at a location of the hold affordance and a new screen having “find my phone” and “end-call” affordances is displayed). The third affordance, when activated, causes a cellular phone in wireless communication with the electronic device to provide at least one of an audible output, a visual output, or a haptic output, and the fourth affordance, when activated, causes the call to be ended.

[0265] FIG. 12 is a flow diagram illustrating process 1200 for handling phone calls. Process 1200 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 1202, a phone icon is displayed. The phone icon may be among a plurality of other icons for launching applications. At block 1204, user selection of the phone icon is detected. Processing proceeds to block 1206, where in response to the user selection, a phone landing screen is displayed. The phone landing screen is screen 610 (FIG. 6A) in some embodiments. The phone landing screen may have one or more affordances for accessing features such as phonebook contacts, user-designated favorite contacts, recent incoming and/or outgoing calls, and voicemail messages. Phone contacts are displayed responsive to a user selection of the contact or user-designated favorites affordance. Optionally, the recent calls affordance and the voicemail affordance may have a numeral that is displayed when there are new missed calls and voicemail messages. In some embodiments the phone landing screen is responsive to input from a rotatable input mechanism.

[0266] FIG. 13 is a flow diagram illustrating process 1300 for handling phone calls between devices. Process 1300 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 1302, a first communication status between a phone headset and the electronic device is determined. This first communication status indicates whether the phone headset is operatively connected to the electronic device. At block 1304, a second communication status is determined. This second communication indicates whether the phone headset and the cellular phone are operatively connected. At block 1306, an indication of at least one of the first and second statutes is displayed. In some embodiments this status is indicator 611 (FIG. 6A). In some embodiments this status is indicator is indicator 714 (FIG. 7B). In some embodiments, this status indicator is indicator 733 (FIG. 7B). In some embodiments, this status indicator is indicator 744 (FIG. 7C). In some embodiments, processing after block 1306 proceeds to block 1308 where a third communication status is determined. The third communication status indicates whether the electronic device is operatively connected to the cellular phone. This third status is displayed in some embodiments as part of affordance 714 (FIG. 7B), affordance 813 (FIG. 8B) and/or affordance 914 (FIG. 9B), for example. The first, second, and/or third communication statuses may be used to control the handling of phone call operations between multiple electronic devices under the scenarios summarized in table 1 and described with respect to FIGS. 7A-7E, 8A-8E, and 9A-B.

[0267] FIG. 14 is a flow diagram illustrating process 1400 for handling phone calls between devices. Process 1400 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 1402, during an active phone call, a touch on the touch-sensitive display is detected as having a characteristic intensity. The touch may be located at the position of a first affordance. As used herein, “active” phone calls includes calls being made (where the recipient has not answered), incoming calls (where the user of the electronic device has not answered), and in-progress calls (where the user of the electronic device and at least one other party is connected). At block 1404, the device determines whether the characteristic intensity exceeds a predetermined threshold intensity. If the characteristic intensity exceeds a predetermined threshold intensity, processing proceeds to block 1406 where the electronic device sends an instruction to a cellular phone instructing the cellular phone to display a second affordance. Optionally, the electronic device may display a secondary functions screen such as 1020 (FIG. 10B), and wait for an optional user input such as a selection of affordance 1024 (FIG. 10B), before sending the instruction. The second affordance, if selected, causes the cellular phone to retrieve the active phone call, and to utilize its microphone and speaker to carry on the call. If the characteristic intensity is below the predetermined threshold intensity, processing proceeds to block 1408, where the electronic device performs a function associated with the first affordance at the location of the lower intensity touch.

[0268] FIG. 15 is a flow diagram illustrating process 1500 for handling phone calls between devices. Process 1500 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 1502, displaying, on the touch-sensitive display of an electronic device, an indication of an incoming call that is being received on a cellular phone that is within communications range of the electronic device. At block 1504, the electronic device displays at least an affordance for answering the call and an affordance for declining call. At block 1506, the electronic device receives user input other than a selection of the accept and decline affordances, which causes the electronic device to, at block 1508, display an affordance for passing the call to the cellular phone by placing the call on hold and by sending an instruction to the cellular phone instructing the cellular phone to display a second answer affordance, where the second answer affordance, when selected, causes the cellular phone to answer the incoming call. In some embodiments, the user input other than the selection of the accept and decline affordances is an upward swipe.

[0269] FIG. 16 shows exemplary functional blocks of an electronic device 1600 that, in some embodiments, performs the above-described features. As shown in FIG. 16, an electronic device 1600 may include display unit 1602 configured to display graphical objects; human input interface unit 1604 configured to receive user input; one or more RF units 1606 configured to detect and communicate with external electronic devices; one or more feedback unit configured to provide user with haptic, audio, and/or visual feedback; and processing unit 1610 coupled to display unit 1602, human input interface unit 1604, RF unit(s) 1606, and feedback unit 1608. In some embodiments, processing unit 1612 is configured to support a phone unit 1612, a pairing status unit 1614, and a display enabling unit 1616.

[0270] In some embodiments, display enabling unit 1616 is configured to cause a display of a user interface (or portions of a user interface) in conjunction with the display unit 1602. For example, the display enabling unit 1616 may be used for display one or more of the user interface screens described with reference to FIGS. 6A-6H.

[0271] In some embodiments, pairing status unit 1614 is configured to determine the connection status between (i) a wearable electronic device and a headset; (ii) a wearable electronic device and a cellular phone, and/or (iii) a cellular phone and a headset. This status information is provided to display enabling unit 1616 so that display unit 1602 can display one or more of the status. This status information is also provided to phone unit 1612 so that phone unit 1612 can handle incoming and outgoing calls appropriate as discussed, for example, with reference to FIGS. 7A-7E, 8A-8E, 9A-B, 10A-10C, and/or 11A-11B.

[0272] In some embodiments, phone unit 1612 is configured to receive information from, among others, pairing status unit 1614 to determine what devices are to be used to carry on a call. For example, when pairing status unit 1614 determines that a headset is operatively connected to a cellular phone that is in turn operatively connected to device 1600, upon answering the call, phone unit 1612 may cause the headset to be used for carrying on the call. As another example, when pairing status unit 1614 determines that a headset is operatively connected to device 1600, but a cellular phone is not operatively connected to device 1600, phone unit 1612 may present a subset of phone functions for operation on device 1600.

[0273] The units of FIG. 16 may be used to implement the various techniques and methods described above with respect to FIGS. 6-15. The units of device 1600 are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described examples. It is understood by persons of skill in the art that the functional blocks described in FIG. 16 are, optionally, combined or separated into sub-blocks to implement the principles of the various described examples. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

[0274] In accordance with some embodiments, FIG. 17 shows a functional block diagram of an electronic device 1700 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 17 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments.

[0275] As shown in FIG. 17, an electronic device 1700 includes a display unit 1702 configured to display a graphic user interface, a touch sensitive surface unit 1704 configured to receive contacts, and a processing unit 1706 coupled to the display unit 1702 and the touch-sensitive surface unit 1704. In some embodiments, the processing unit includes a display enabling unit 1708, a detecting unit 1710, a scrolling unit 1712, and an initiating unit 1714.

[0276] The processing unit 1706 is configured to enable display (e.g., with the display enabling unit 1708) of a phone icon; and detect (e.g., with the detecting unit 1710) user selection of the phone icon. The processing unit 1706 is further configured to, in response to the user selection, enable display (e.g., with the display enabling unit 1708) of at least two affordances comprising: a first affordance, wherein the first affordance, when selected, enables display of a plurality of phone contacts; and a second affordance, wherein the second affordance, when selected, enables display of a user-designed subset of the plurality of phone contacts. The processing unit is further configured to, while enabling display of the first and second affordances, detect (e.g., with the detecting unit 1710) user input comprising at least a selection of a displayed affordance; and in response to detecting the user input, enable display (e.g., with the display enabling unit 1708) of one or more phone contacts.

[0277] In some embodiments, the processing unit is further configured to, in response to the user selection, enable display (e.g., with the display enabling unit 1708) of a third affordance, wherein the third affordance when selected causes the electronic device to display a plurality of affordances representing voice mail messages.

[0278] In some embodiments, the processing unit is further configured to, in response to the user selection, enable display (e.g., with the display enabling unit 1708) of a fourth affordance, wherein the fourth affordance when selected causes the electronic device to display a plurality of recent calls.

[0279] In some embodiments, the second affordance includes, within its perimeter, an indication of a number of missed incoming calls.

[0280] In some embodiments, the fourth affordance includes, within its perimeter, an indication of a number of new voicemail messages.

Process 2100 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 2102, the electronic device may receive an indication of an event. The indication may be an indication of an incoming call and may be received from a cellular phone or another connected to an electronic device. At block 2104, in response to receiving the indication, the electronic device may provide an event notification. Providing an event notification may include providing an output (e.g., a visual output such as a flashing light or indication on a display, an audible output such as a ringtone, a haptic output such as vibration) to notify a user of an incoming call. At block 2106, while providing the event notification, the electronic device may receive data, from one or more motion sensors, representing a user input. The user input may correspond to a user physically raising a wrist. At block 2108, the electronic device may determine, based on the data representing the user input, whether the user input corresponds to movement of the electronic device satisfying predetermined condition. The predetermined condition may include a wrist raise, that the electronic device is moved to a particular position (e.g., rotated), activation of an input device such as a push button or a rotatable input device, or a touch on a touch-sensitive surface or display. At block 2110, in accordance with a determination that the user input corresponds to movement of the electronic device satisfying the predetermined condition (e.g., wrist raise), the electronic device may modify the event notification. Modifying the event notification may include varying, increasing, or decreasing (e.g., attenuating) visual intensity, haptic intensity, and/or a volume level of the notification, for instance, to a non-negative value including zero.

[0342] In some embodiments, in accordance with a determination that the user input does not correspond to movement of the electronic device satisfying the predetermined condition, the electronic device may forgo modification of the event notification.

[0343] In some embodiments, the electronic device wirelessly communicates with a cellular phone, and the indication of the event is an indication of a call received at the cellular phone.

[0344] In some embodiments, the predetermined condition is based on an amount of lifting of the electronic device during a time interval, the amount of lifting determined from an accelerometer of the electronic device, the predetermined condition is based on smoothness of a lifting of the electronic device during a time interval, the smoothness of the lifting determined from an accelerometer of the electronic device, and/or the predetermined condition comprises a minimum period of dwell time in a position in accordance with the lifting of the electronic device.

[0345] In some embodiments, in accordance with providing the event notification, the electronic device may provide the event notification while a display of the electronic device is inactive (e.g., display of electronic device is turned off).

[0346] In some embodiments, in accordance with modifying the event notification, the electronic device may activate the display of the electronic device. For example, the electronic device may activate a display of the electronic device in response to the predetermined condition being satisfied.

[0347] In some embodiments, in accordance with determining, based on the data representing the user input, whether the user input corresponds to movement of the electronic device satisfying a predetermined condition, the electronic device may determine whether the user input corresponds to activation an input device of the electronic device, and further in accordance with a determination that the user input corresponds to activation of the input device, may modify the event notification. By way of example, when determining whether the user input corresponds to movement of the electronic device, the electronic device can determine if a user input causes a display (or other input device) of the electronic device to be enabled, and in accordance with that determination, can modify/attenuate the notification.

[0348] In some embodiments, the electronic device may be configured to wirelessly communicate with a cellular phone, and in accordance with a determination that the user input corresponds to movement of the electronic device satisfying the predetermined condition, the electronic device may modify an event notification provided by the cellular phone. By way of example, in accordance with a determination that the user input corresponds to movement of the electronic device satisfying the predetermined threshold, the electronic device can modify a notification provided by an operatively and/or wirelessly connected cellular phone.

[0371] The operations described above with reference to FIG. 21 are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 22. For example, receiving operations 2102 and 2106, providing operation 2104, determining operation 2108, and modifying operation 2110 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 17 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally uses or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

[0372] The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated.

[0373] Additional exemplary user interfaces for transitioning between wearable electronic device and cellular phone usage are discussed with reference to FIGS. 23A-B. As shown in FIG. 23A, cellular phone 2302 is receiving an incoming call and displays incoming-call screen 2330. Cellular phone 2302 is device 100 (FIG. 1A) in some embodiments. Wearable electronic device 2300 receives an indication of the incoming call from cellular phone 2302 and also displays incoming-call screen 2310. Wearable electronic device 2300 is device 500 (FIG. 5A) in some embodiments. Optionally, wearable electronic device 2300 may issue a haptic or audio alert informing the user of the incoming call.

[0374] Incoming-call screen includes affordance 2312 for answering the call. Consistent with the discussion above regarding usage scenarios, if affordance 2312 is selected to answer the incoming call while cellular phone 2302 is operatively connected to a headset, the headset will be used for carrying on the call. A user may wish, however, to participate on the call using another device, such as by using the internal speaker and microphone of cellular phone 2302.

[0375] In this situation, while incoming-call screen 2310 is displayed on wearable electronic device 2300, the user may provide swipe input 2318 to reveal affordance 2320. Affordance 2320, when selected, causes the incoming call to be placed on hold so that the user can access cellular phone 2302 to answer the call. As shown in FIG. 23A and continuing onto FIG. 23B, in response to selection 2322 of affordance 2320, the incoming call is placed on hold, and cellular phone 2302 displays on-hold screen 2340 informing the user via instruction label 2342 that the phone call can be retrieved by certain user input, in this case a swipe input. In the illustrated example, incoming call screen 2310 has affordance 2316 indicating the availability of additional features that are not displayed, such as affordance 2312 for answering the call cellular phone 2302.

[0376] The user can retrieve the call on cellular phone 2302 by swipe input 2344, which causes cellular phone 2302 to un-hold the call and enable its speaker and microphone for participation in the call. As shown, responsive to swipe input 2344, device 2350 un-holds the phone call and transitions to in-call screen 2350. In the meantime, wearable electronic device 2300 returns to user interface screen 2352, in this case a music playback screen that was displayed prior to the incoming call. Note that, while call-holding screen 2350 is displayed on wearable electronic device 2300, the user may select un-hold affordance 2352 to continue with the call as before, meaning to continue using the headset for communication. Restated, the user may “pull back” the call even after selecting affordance 2320 (FIG. 23A) to pass the call to cellular phone 2302.

[0377] In addition to affordance 2320, incoming-call screen 2310 may include affordances for accessing other phone-related features. For example, with reference to FIG. 23A, the user may provide swipe input 2318 to reveal affordance 2324 in addition to affordance 2420. Affordance 2324, when selected, may allow a user may reply with a text message (e.g., using a messaging dialog box), instead of verbally answering the incoming call. By way of example, a user may for instance, indicate that the user is busy and cannot talk with the caller at the time of the call. In some instances, a user may also wish to send other messages such as those containing emoji. It will be appreciated by those in the art that a user may provide any message to the caller using one or more known formats and/or lengths. U.S. Provisional Patent Application Ser. No. 62/044,923, entitled “USER INTERFACE FOR RECEIVING USER INPUT,” filed Sep. 2, 2014; and U.S. Provisional Patent Application Ser. No. 62/127,800, entitled “USER INTERFACE FOR RECEIVING USER INPUT,” filed Mar. 3, 2015 describe user interfaces for efficiently obtaining user input that would be helpful in the context of incoming-calls screen 2310. Each of these applications which is hereby incorporated by reference in their entirety. For example, incoming-calls screen 2310 can provide access to affordances for ignoring an incoming call and sending a suggested response, such as “can I call you back?” to the caller. As another example, incoming-calls screen 2310 can provide access to affordances for selecting and customizing an emoji to be sent to the caller. As an additional example, incoming-calls screen 2310 can provide access to an interface for transcribing a user's speech utterance into a message for the caller. As yet another example, incoming-calls screen 2310 can provide access to a reduce-sized keyboard interface for inputting a message for the caller.

[0378] In some examples, a user may wish to learn and/or confirm the location of the cellular phone prior to or after selecting the affordance 2320. Accordingly, in some examples, the incoming call screen 2310, and/or one or more other screens displayed by the electronic device, may include additional affordances, such as an affordance directed to “pinging” the cellular phone. The pinging affordance, when selected, may cause the cellular phone to provide an audible, haptic, and/or visual output. An audible output, for example, can be a short, ringing sound for useful for attracting the user's attention. Once the output has been provided, the user may thereafter locate the phone based on the output. In some embodiments, the affordance to ping the phone is displayed in response selecting affordance 2320 to place the call on hold.

[0379] FIG. 24 is a flow diagram illustrating process 2400 for handling phone calls between devices. Process 2400 may be carried out by electronic devices such as devices 100, 300, and/or 500 (FIGS. 1A, 3A, 5A) in various embodiments. At block 2402, displaying, on the touch-sensitive display of an electronic device, is an indication of an incoming call. In some examples, the call is being received on a cellular phone that is within communications range of the electronic device. At block 2404, the electronic device displays at least an affordance for answering the call and at least one an affordance for declining call. At block 2406, the electronic device receives user input other than a selection of the accept and decline affordances. The user input causes the electronic device to, at block 2408, display an affordance for messaging the caller. In some embodiments, the user input other than the selection of the accept and decline affordances is an upward swipe.

[0380] The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
