Location-based categorical information services

[0001] This application claims priority to U.S. Provisional Patent Application Ser. No. 60/946,825 filed Jun. 28, 2007, and entitled “LOCATION-BASED CATEGORICAL INFORMATION SERVICES,” the contents of which are incorporated herein by reference.

[0002] The subject matter of this patent application is generally related to mobile devices.

[0003] Mobile devices have grown more powerful and feature-rich and now include such features as personal digital assistant (PDA) capabilities, cameras to capture video and still images, Internet access, etc. Location-based services have been developed for determining and tracking the locations of the users of mobile devices. Location-based services provide location-specific information to mobile devices, including for example, global positioning system (GPS) data to locate the mobile device on a map of a geographic region.

[0004] Some examples of location-based information include listings of events and sites of interest. A user wishing to gain this information can search the Internet, visit the local tourism office, or consult a travel guide or a local newspaper. However, these approaches require the user to actively search a resource, can be time-consuming, can provide outdated information, and can produce a large amount of information that may be of little interest to the user.

[0005] Location-based information services can be provided to a user through a mobile device by providing categorical information from a network resource. The categorical information can be provided based on user preferences and/or a geographic location of the mobile device. Additionally, the user can provide location-based information to a network-based repository and/or service, where the user-provided information can be used to enrich information provided to other users.

[0006] In some implementations, a method includes: receiving first information associated with a category of interest from a mobile device; receiving second information identifying a geographic location of the mobile device; determining categorical information using the first information and the second information; and providing the categorical information to the mobile device as a data structure containing information used by the mobile device to represent the categorical information on a map by a graphical object.

[0007] In some implementations, a system includes a positioning system operable to obtain a current location of a mobile device, a data structure including a set of categorical information, and a map application operable to provide a display of a map. In some implementations, the map can include a graphical representation of an item in the set of categorical information, where the graphical representation can be displayed at a location corresponding to an address of the item.

[0008] In some implementations, a method includes: providing first information associated with a category of interest; providing second information associated with a location of a mobile device; receiving categorical information using the first information and the second information; receiving categorical information determined based on the first information and the second information; and displaying a map including graphical representations of one or more items in the categorical information, where the graphical representations are displayed at locations corresponding to addresses of the one or more items, and wherein the graphical representations are displayed based on a zoom level of the map.

[0009] Other implementations are disclosed, including implementations directed to systems, methods, apparatuses, computer-readable mediums and user interfaces.

[0020] FIG. 1 is a block diagram of an example mobile device 100. The mobile device 100 can be, for example, a handheld computer, a personal digital assistant, a cellular telephone, a network appliance, a camera, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a network base station, a media player, a navigation device, an email device, a game console, or other electronic device, a combination of any two or more of these data processing devices or other data processing devices.

[0021] In some implementations, the mobile device 100 includes a touch-sensitive display 102. The touch-sensitive display 102 can implement liquid crystal display (LCD) technology, light emitting polymer display (LPD) technology, or some other display technology. The touch-sensitive display 102 can be sensitive to haptic and/or tactile contact with a user.

[0022] In some implementations, the touch-sensitive display 102 can comprise a multi-touch-sensitive display 102. A multi-touch-sensitive display 102 can, for example, process multiple simultaneous touch points, including processing data related to the pressure, degree and/or position of each touch point. Such processing facilitates gestures and interactions with multiple fingers, chording, and other interactions. Other touch-sensitive display technologies can also be used, e.g., a display in which contact is made using a stylus or other pointing device. Some examples of multi-touch-sensitive display technology are described in U.S. Pat. Nos. 6,323,846, 6,570,557, 6,677,932, and U.S. Patent Publication 2002/0015024A1, each of which is incorporated by reference herein in its entirety.

[0023] In some implementations, the mobile device 100 can display one or more graphical user interfaces on the touch-sensitive display 102 for providing the user access to various system objects and for conveying information to the user. In some implementations, the graphical user interface can include one or more display objects 104, 106. In the example shown, the display objects 104, 106, are graphic representations of system objects. Some examples of system objects include device functions, applications, windows, files, alerts, events, or other identifiable system objects.

[0024] In some implementations, the mobile device 100 can implement multiple device functionalities, such as a telephony device, as indicated by a phone object 110; an e-mail device, as indicated by the e-mail object 112; a network data communication device, as indicated by the Web object 114; a Wi-Fi base station device (not shown); and a media processing device, as indicated by the media player object 116. In some implementations, particular display objects 104, e.g., the phone object 110, the e-mail object 112, the Web object 114, and the media player object 116, can be displayed in a menu bar 118. In some implementations, device functionalities can be accessed from a top-level graphical user interface, such as the graphical user interface illustrated in FIG. 1. Touching one of the objects 110, 112, 114 or 116 can, for example, invoke corresponding functionality.

[0025] In some implementations, the mobile device 100 can implement network distribution functionality. For example, the functionality can enable the user to take the mobile device 100 and its associated network while traveling. In particular, the mobile device 100 can extend Internet access (e.g., Wi-Fi) to other wireless devices in the vicinity. For example, mobile device 100 can be configured as a base station for one or more devices. As such, mobile device 100 can grant or deny network access to other wireless devices.

[0026] In some implementations, upon invocation of device functionality, the graphical user interface of the mobile device 100 changes, or is augmented or replaced with another user interface or user interface elements, to facilitate user access to particular functions associated with the corresponding device functionality. For example, in response to a user touching the phone object 110, the graphical user interface of the touch-sensitive display 102 may present display objects related to various phone functions; likewise, touching of the email object 112 may cause the graphical user interface to present display objects related to various e-mail functions; touching the Web object 114 may cause the graphical user interface to present display objects related to various Web-surfing functions; and touching the media player object 116 may cause the graphical user interface to present display objects related to various media processing functions.

[0027] In some implementations, the top-level graphical user interface environment or state of FIG. 1 can be restored by pressing a button 120 located near the bottom of the mobile device 100. In some implementations, each corresponding device functionality may have corresponding “home” display objects displayed on the touch-sensitive display 102, and the graphical user interface environment of FIG. 1 can be restored by pressing the “home” display object.

[0028] In some implementations, the top-level graphical user interface can include additional display objects 106, such as a short messaging service (SMS) object 130, a calendar object 132, a photos object 134, a camera object 136, a calculator object 138, a stocks object 140, a weather object 142, a maps object 144, a notes object 146, a clock object 148, an address book object 150, and a settings object 152. Touching the SMS display object 130 can, for example, invoke an SMS messaging environment and supporting functionality; likewise, each selection of a display object 132, 134, 136, 138, 140, 142, 144, 146, 148, 150 and 152 can invoke a corresponding object environment and functionality.

[0029] Additional and/or different display objects can also be displayed in the graphical user interface of FIG. 1. For example, if the device 100 is functioning as a base station for other devices, one or more “connection” objects may appear in the graphical user interface to indicate the connection. In some implementations, the display objects 106 can be configured by a user, e.g., a user may specify which display objects 106 are displayed, and/or may download additional applications or other software that provides other functionalities and corresponding display objects.

[0030] In some implementations, the mobile device 100 can include one or more input/output (I/O) devices and/or sensor devices. For example, a speaker 160 and a microphone 162 can be included to facilitate voice-enabled functionalities, such as phone and voice mail functions. In some implementations, a loud speaker 164 can be included to facilitate hands-free voice functionalities, such as speaker phone functions. An audio jack 166 can also be included for use of headphones and/or a microphone.

[0031] In some implementations, a proximity sensor 168 can be included to facilitate the detection of the user positioning the mobile device 100 proximate to the user's ear and, in response, to disengage the touch-sensitive display 102 to prevent accidental function invocations. In some implementations, the touch-sensitive display 102 can be turned off to conserve additional power when the mobile device 100 is proximate to the user's ear.

[0032] Other sensors can also be used. For example, in some implementations, an ambient light sensor 170 can be utilized to facilitate adjusting the brightness of the touch-sensitive display 102. In some implementations, an accelerometer 172 can be utilized to detect movement of the mobile device 100, as indicated by the directional arrow 174. Accordingly, display objects and/or media can be presented according to a detected orientation, e.g., portrait or landscape. In some implementations, the mobile device 100 may include circuitry and sensors for supporting a location determining capability, such as that provided by the global positioning system (GPS) or other positioning systems (e.g., systems using Wi-Fi access points, television signals, cellular grids, Uniform Resource Locators (URLs)). In some implementations, a positioning system (e.g., a GPS receiver) can be integrated into the mobile device 100 or provided as a separate device that can be coupled to the mobile device 100 through an interface (e.g., port device 190) to provide access to location-based services.

[0033] The mobile device 100 can also include a camera lens and sensor 180. In some implementations, the camera lens and sensor 180 can be located on the back surface of the mobile device 100. The camera can capture still images and/or video.

[0034] The mobile device 100 can also include one or more wireless communication subsystems, such as an 802.11b/g communication device 186, and/or a Bluetooth™ communication device 188. Other communication protocols can also be supported, including other 802.x communication protocols (e.g., WiMax, Wi-Fi, 3G), code division multiple access (CDMA), global system for mobile communications (GSM), Enhanced Data GSM Environment (EDGE), etc.

[0035] In some implementations, a port device 190, e.g., a Universal Serial Bus (USB) port, or a docking port, or some other wired port connection, can be included. The port device 190 can, for example, be utilized to establish a wired connection to other computing devices, such as other communication devices 100, network access devices, a personal computer, a printer, or other processing devices capable of receiving and/or transmitting data. In some implementations, the port device 190 allows the mobile device 100 to synchronize with a host device using one or more protocols, such as, for example, the TCP/IP, HTTP, UDP and any other known protocol. In some implementations, a TCP/IP over USB protocol can be used.

[0036] FIG. 2 is a block diagram of an example network operating environment 200 for the mobile device 100 of FIG. 1. The mobile device 100 of FIG. 1 can, for example, communicate over one or more wired and/or wireless networks 210 in data communication. For example, a wireless network 212, e.g., a cellular network, can communicate with a wide area network (WAN) 214, such as the Internet, by use of a gateway 216. Likewise, an access point 218, such as an 802.11g wireless access point, can provide communication access to the wide area network 214. In some implementations, both voice and data communications can be established over the wireless network 212 and the access point 218. For example, the mobile device 100a can place and receive phone calls (e.g., using VoIP protocols), send and receive e-mail messages (e.g., using POP3 protocol), and retrieve electronic documents and/or streams, such as web pages, photographs, and videos, over the wireless network 212, gateway 216, and wide area network 214 (e.g., using TCP/IP or UDP protocols). Likewise, the mobile device 100b can place and receive phone calls, send and receive e-mail messages, and retrieve electronic documents over the access point 218 and the wide area network 214. In some implementations, the mobile device 100 can be physically connected to the access point 218 using one or more cables and the access point 218 can be a personal computer. In this configuration, the mobile device 100 can be referred to as a “tethered” device.

[0037] The mobile devices 100a and 100b can also establish communications by other means. For example, the wireless device 100a can communicate with other wireless devices, e.g., other wireless devices 100, cell phones, etc., over the wireless network 212. Likewise, the mobile devices 100a and 100b can establish peer-to-peer communications 220, e.g., a personal area network, by use of one or more communication subsystems, such as the Bluetooth™ communication device 188 shown in FIG. 1. Other communication protocols and topologies can also be implemented.

[0038] The mobile device 100 can, for example, communicate with one or more services 230, 240, 250, 260 and 280 and/or one or more content publishers 270 over the one or more wired and/or wireless networks 210. For example, a navigation service 230 can provide navigation information, e.g., map information, location information, route information, and other information, to the mobile device 100. In the example shown, a user of the mobile device 100b has invoked a map functionality, e.g., by pressing the maps object 144 on the top-level graphical user interface shown in FIG. 1, and has requested and received a map for the location “1 Infinite Loop, Cupertino, Calif.”

[0039] A messaging service 240 can, for example, provide e-mail and/or other messaging services. A media service 250 can, for example, provide access to media files, such as song files, movie files, video clips, and other media data. One or more other services 260 can also be utilized by the mobile device 100.

[0040] The mobile device 100 can also access other data and content over the one or more wired and/or wireless networks 210. For example, content publishers, e.g., content publisher(s) 270, such as news sites, RSS feeds, web sites, blogs, social networking sites, developer networks, etc., can be accessed by the mobile device 100. Such access can be provided by invocation of a web browsing function or application (e.g., a browser) in response to a user touching the Web object 114.

[0041] An information service 280 can include multiple content repositories populated with data regarding items of interest that are categorized. The information service block 280 can receive preferences and location information to generate categorical information as output. In some implementations, the information service block 280 is a network resource which can be accessed through a network connection (e.g., the Internet, wireless network).

[0042] FIG. 3 is a block diagram 300 of an example implementation of the mobile device 100 of FIG. 1. The mobile device 100 can include a memory interface 302, one or more data processors, image processors and/or central processing units 304, and a peripherals interface 306. The memory interface 302, the one or more processors 304 and/or the peripherals interface 306 can be separate components or can be integrated in one or more integrated circuits. The various components in the mobile device 100 can be coupled by one or more communication buses or signal lines.

[0043] Sensors, devices and subsystems can be coupled to the peripherals interface 306 to facilitate multiple functionalities. For example, a motion sensor 310, a light sensor 312, and a proximity sensor 314 can be coupled to the peripherals interface 306 to facilitate the orientation, lighting and proximity functions described with respect to FIG. 1. Other sensors 316 can also be connected to the peripherals interface 306, such as a positioning system (e.g., GPS receiver), a temperature sensor, a biometric sensor, or other sensing device, to facilitate related functionalities.

[0044] A camera subsystem 320 and an optical sensor 322, e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips.

[0045] Communication functions can be facilitated through one or more wireless communication subsystems 324, which can include radio frequency receivers and transmitters and/or optical (e.g., infrared) receivers and transmitters. The specific design and implementation of the communication subsystem 324 can depend on the communication network(s) over which the mobile device 100 is intended to operate. For example, a mobile device 100 may include communication subsystems 324 designed to operate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi or WiMax network, and a Bluetooth™ network. In particular, the wireless communication subsystems 324 may include hosting protocols such that the device 100 may be configured as a base station for other wireless devices.

[0046] An audio subsystem 326 can be coupled to a speaker 328 and a microphone 330 to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and telephony functions.

[0047] The I/O subsystem 340 can include a touch screen controller 342 and/or other input controller(s) 344. The touch-screen controller 342 can be coupled to a touch screen 346. The touch screen 346 and touch screen controller 342 can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, 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 the touch screen 346.

[0048] The other input controller(s) 344 can be coupled to other input/control devices 348, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of the speaker 328 and/or the microphone 330.

[0049] In one implementation, a pressing of the button for a first duration may disengage a lock of the touch screen 346; and a pressing of the button for a second duration that is longer than the first duration may turn power to the mobile device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 346 can, for example, also be used to implement virtual or soft buttons and/or a keyboard.

[0050] In some implementations, the mobile device 100 can present recorded audio and/or video files, such as MP3, AAC, and MPEG files. In some implementations, the mobile device 100 can include the functionality of an MP3 player, such as an iPod™. The mobile device 100 may, therefore, include a 36-pin connector that is compatible with the iPod. Other input/output and control devices can also be used.

[0051] The memory interface 302 can be coupled to memory 350. The memory 350 can include high-speed random access memory and/or non-volatile memory, such as one or more magnetic disk storage devices, one or more optical storage devices, and/or flash memory (e.g., NAND, NOR). The memory 350 can store an operating system 352, such as Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks. The operating system 352 may include instructions for handling basic system services and for performing hardware dependent tasks. In some implementations, the operating system 352 can be a kernel (e.g., UNIX kernel).

[0052] The memory 350 may also store communication instructions 354 to facilitate communicating with one or more additional devices, one or more computers and/or one or more servers. The memory 350 may include graphical user interface instructions 356 to facilitate graphic user interface processing; sensor processing instructions 358 to facilitate sensor-related processing and functions; phone instructions 360 to facilitate phone-related processes and functions; electronic messaging instructions 362 to facilitate electronic-messaging related processes and functions; web browsing instructions 364 to facilitate web browsing-related processes and functions; media processing instructions 366 to facilitate media processing-related processes and functions; GPS/Navigation instructions 368 to facilitate GPS and navigation-related processes and instructions; camera instructions 370 to facilitate camera-related processes and functions; security process instructions 372, activation record/IMEI 374, and information services instructions 376.

[0053] Each of the above identified instructions and applications can correspond to a set of instructions for performing one or more functions described above. These instructions need not be implemented as separate software programs, procedures or modules. The memory 350 can include additional instructions or fewer instructions. Furthermore, various functions of the mobile device 100 may be implemented in hardware and/or in software, including in one or more signal processing and/or application specific integrated circuits.

[0054] FIG. 4 is a block diagram of an example implementation of the information service block 280 of FIG. 2. The information service block 280 includes multiple content repositories 410a, 410b . . . 410n and a filter 420. The information service block 280 can receive preferences and location information as input, and generates filtered information services as output. In some implementations, the information service block 280 is a network resource which can be accessed through a network connection (e.g., the Internet, wireless network).

[0055] The content repositories 410 or content databases store location-based information. Some examples of location-based content items include information about points of interest (e.g., museums, zoos, historical sites, famous homes), shopping (e.g., specialty stores, jewelry, music stores, antiques), and information about local activities (e.g., hiking, skydiving, birdwatching). In some implementations, the location-based information can be indexed (e.g., an inverse index) in the content repositories 410 by geographic location or region, such as, for example, by metropolitan region, county, town, zip code, or telephone area code.

[0056] The information service block 280 can receive from the mobile device 100, through the wired and/or wireless networks 210, preferences and location information, e.g., user preferences and user geographic location information. The geographic location information can be provided by the mobile device 100 using GPS or other positioning systems (e.g., systems using Wi-Fi access points, television signals, cellular grids, or URLs). The geographic location information can be received, for example, as latitudinal and longitudinal coordinates, as a region associated with a Wi-Fi access point, or as a metropolitan region, a county, or a town. In some implementations, the mobile device 100 pushes geographic location information to the information service block 280 through the wired and/or wireless networks 210.

[0057] In some implementations, user preferences can define the types of location-based information the user of the mobile device 100 wishes to receive. For example, the user can choose to receive certain categories of information. Setting preferences for information services is described in more detail with reference to FIGS. 5A-5B. In some implementations, if the user preferences have not been set, the information service block 280 can use default settings for the mobile device 100.

[0058] The filter 420 of the information service block 280 can receive as an input user preferences, location information, and/or location-based information from the content repositories 410. In some implementations, the filter 420 also receives location-based information from content repositories or servers remote to the information service block 280. The output of the filter 420 and the information service block 280 is categorical information that conforms to the input preferences and that can be location-specific, based on the input location information. In some implementations, the location-based information is stored on the mobile device 100, and filtering of the location-based information is performed by the mobile device 100.

[0059] FIG. 5A illustrates an example 500 of selecting categorical information and setting preferences for location-based information services provided by the mobile device 100 of FIG. 1. The example 500 uses a graphical user interface with a tabbed window which can be displayed in, for example, the touch-sensitive display 102 of the mobile device 100, or in a display of an access device 218 (e.g., a personal computer) when the mobile device 100 is in communication with the access device 218. For example, a mobile service application of the access device 218 can allow a user to set preferences for the location-based information services.

[0060] In this example, a user of the mobile device 100 can choose to receive categorical information corresponding to restaurants 502, hotels 504, movie theaters information and listings 506, sports venues information and schedules 508, and museums 508. The user can select the types of categorical information to be retrieved by checking the corresponding checkbox 512 for the desired topic. In the example 500, the user has set the preferences for the location-based information services by choosing to receive categorical information related only to museums 508. In some implementations, more than one category can be selected or a new category can be input by the user using, e.g., the touch-sensitive display 102 of the mobile device 100. In some implementations, one or more of the categories shown in FIG. 5A can have subcategories that can be selected to further refine the information to be provided to the mobile device. The subcategories can be accessed through menus or other control structures.

[0061] In some implementations, the user sets the preferences at the time the mobile device 100 is configured or activated. The user can modify the preference settings at a later date. In some implementations, the first time a user requests location-based information services (e.g., by selecting the information services object 122 of FIG. 1), the user is presented with the information services selection interface, such as the tabbed window in example 500.

[0062] FIG. 5B illustrates an example 530 of other settings for categorical information provided to the mobile device 100. In an implementation, a user can share categorical information with others. In the example 500, a user can enable sharing 514 and define how the categorical information is to be shared using checkboxes 524 (e.g., with everyone 516 or only with contacts on a “buddy list” 518). In another implementation, a user can set a preference to enable others to update the categorical information. In the example 500, a checkbox 524 is provided to allow updates 520 by others (i.e., everyone 516 or only buddy list contacts 518, as specified by a user).

[0063] In an implementation, automatic updates 522 to the categorical information can be provided to the mobile device 100. For example, if a user selects museums 508, and a new museum opens or updates its content, the categorical information provided to the mobile device 100 can be updated automatically to reflect the updated information.

[0064] Referring now to FIGS. 6A-B, an example of user interface 600 that displays graphical objects 602, 604 and 606 representing the locations of items of interest that satisfy a request for categorical information (e.g. museums). In an implementation, the graphical objects 602, 604 and 606 appear as push pins that are “pinned” to a map at their corresponding locations. In one implementation, the user can define a setting within the mobile device 100 to specify a proximity condition that must be satisfied by an item before a push pin is shown on the map representing an item that satisfies a condition. In an example, the proximity condition can specify that the item's location be within a certain radius of the current location of the mobile device 100 in order to be displayed on the map 600. In some implementations, the categorical information can be manually updated in response to a user selection of an update option.

[0065] In yet another example, the proximity condition can specify that the item's location be within the geographic parameters of the map displayed to the user in order to be displayed on the map 600. In such an example, if the user selects to “zoom out” the map to display a larger geographical area, then multiple other push pins may appear corresponding to locations within the larger geographical area. In another implementation, the proximity condition can specify that the graphical objects are displayed and/or removed from the map 600 as the displayed map 600 changes to indicate movement of the mobile device 100.

[0066] As mentioned above, each push pin 602, 604 and 606 represents an item that satisfies a condition (e.g., a request for categorical information). If the user desires to retrieve information about a particular item represented by a push pin, the user can select the push pin and information included in the address book is retrieved and provided to the user. For example, in one implementation where the mobile device 100 includes a touch sensitive display (e.g., touch sensitive display 102 shown in FIG. 1), the user can touch a push pin to select the push pin, and the contact information for the item of interest corresponding to the push pin is displayed or otherwise presented to the user (e.g., as an audio and/or video presentation).

[0067] In one implementation, a single touch of the push pin, e.g., a tap on the touch sensitive display can yield a first result and a sustained touch of the push pin can yield a second result (examples of first and second results are described below). In another implementation, where a user can interact with the map 600 using a pointing device (e.g., a joystick), hovering a cursor over the push pin can yield the first result and clicking the push pin can yield the second result.

[0068] Referring now to FIG. 6B, an example of information that can be provided to the user upon selecting a push pin is shown. In this example, the user selected the push pin 604 and a first result is displayed. The first result is displayed in an information balloon 608 superimposed on the map 600. The information balloon 608 includes contact information (e.g., the name, address and telephone number) of the item represented by the push pin 604. In this example, the user tapped on the touch sensitive display 102 in the vicinity of the push pin 604 to yield this first result, being the contact information for this particular item.

[0069] The configuration of the graphical user interface presenting the information balloon 608 can be configured differently and can include different, or more or less information about the item in other implementations.

[0070] Another example of selecting a graphical object, such as, a sustained touch of the push pin, can result in an initiation of a telephone call to the contact telephone number presented as the first result. For example, a sustained touch of the push pin 604 can result in a telephone call being initiated to item of interest represented by the push pin 604. In another implementation, driving directions can be provided from the current location of the mobile device 102 to the item of interest. In yet another implementation, an e-mail can be sent to contacts on a buddy list inviting others to meet the user of the mobile device at the item of interest.

[0071] FIG. 6C is an example mobile device 100 presenting a user interface on the touch sensitive display 102. The user interface includes the map 600 displaying the graphical objects 602, 604 and 606. An input user interface 610 is provided to present options to a user. In an implementation, a user can choose to share the categorical information (e.g., a data structure represented by the graphical objects 602, 604 and 606) through an interface provided by an information service 280. For example, the data representative of the graphical objects 602, 604 and 606 can be stored in the memory 350 of the mobile device 100 and communicated by the wireless communication subsystem 324 to the information service 280 by selecting an upload option. In another implementation, the information service 280 can maintain a version of the data structure that was communicated to the mobile device 100 for access by others. In another implementation, a second mobile device can establish a peer-to-peer connection with the mobile device 100 to receive the data representative of the graphical objects 602, 604 and 606.

[0072] In an implementation, the data at the information service 280 can be shared with others in accordance with access rights as described above regard to FIG. 5B. Other users can retrieve the data from the information service 280 and display the categorical information as graphical objects using another mobile device, personal computer, set-top box, gaming device, portable video player or portable image viewer.

[0073] In an implementation, according to, e.g., a user selection or system setting, data that satisfies the request for categorical information can be manually updated in response to an input. Manual updates can be retrieved from the information service 280 and provided to the mobile device 100 as new or updated information that satisfies the request for categorical information becomes available at the information service 280.

[0074] FIG. 7 is a flow diagram of an example process 700 for providing categorical information to the mobile device 100 of FIG. 1. In an implementation, the example process 700 can be implemented as instructions stored in memory 350 and executed on the processor 304 and/or instructions executed by the information service 280. At stage 702, a user indication is received. For example, a user may input a request for categorical information by using the user interface 500 shown in FIG. 5A that is received by the information service 280.

[0075] At stage 704, a responsive collection of categorical information is determined. For example, in response to the request made by a user, the information service 280 can assemble categorical data responsive to the categorical topic selected by the user in the interface 500 shown in FIG. 5A using a system such as shown in FIG. 4.

[0076] At stage 706, categorical information is received. For example, the mobile device 100 can receive categorical information in a data structure from the information service 280 using the wireless communication subsystem 324.

[0077] At stage 708, the categorical data is displayed. For example, the categorical data is displayed in the touch sensitive display 102, as graphical objects representing items of interest, such as shown in FIGS. 6A and 6B.

[0078] Optionally, at stage 710, the categorical data is updated. For example, in response to a user input or a system setting, updates to the categorical information can be communicated to, or synchronized with, the mobile device 102 to update the display shown in the touch sensitive display 102 or the data stored at the information service 280. The updating/synchronization can be automatic or manually initiated by user input.

[0079] FIG. 8 is a flow diagram of an example process 800 for selected and sharing categorical information. In an implementation, the example process 800 can be implemented as instructions stored in memory 350 and executed on the processor 304 and/or instructions executed by the information service 280. At stage 802, a user indication is received. For example, a user may input a request for categorical information by using the user interface 500 shown in FIG. 5A that is received by the information service 280.

[0080] At stage 804, a responsive collection of categorical information is determined. For example, in response to the request made by a user, the information service 280 can assemble categorical data responsive to the categorical topic selected by the user in the interface 500 shown in FIG. 5A using a system such as shown in FIG. 4.

[0081] At stage 806, categorical information is received. For example, the mobile device 100 can receive categorical information in a data structure from the information service 280 using the wireless communication subsystem 324.

[0082] At stage 808, the categorical data is displayed. For example, the categorical data is displayed in the touch sensitive display 102, as graphical objects representing items of interest, such as shown in FIGS. 6A and 6B.

[0083] At stage 810, an indication to share the categorical data is received. For example, using an interface such as FIGS. 5A and 6C, a user of the mobile device 100 can indicate using the touch sensitive display 102 that the collection of categorical data is to be shared with others. The categorical information can be uploaded from the mobile device 100 to an information service 280, or the information service 280 can retain a version of the categorical data that is made accessible to others.

[0084] At stage 812, a request is received. For example, the information service 280 can receive a request from a second user for the collection of categorical information specified by the user of the mobile device 100. The second user can be authenticated against the access rights set by the user of the mobile device 100.

[0085] At stage 814, the collection of categorical information is provided. For example, the requester of the categorical information can receive the collection created by the user of the mobile device 100 at another mobile device, personal computer, set-top, video player, or image viewer. The collection of categorical data is provided in accordance with the criteria indicated in, for example, FIG. 5B.

[0086] The disclosed embodiments can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of what is disclosed here, or any combination of one or more such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), e.g., the Internet.

[0087] The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
