[0080] FIG. 1 is a diagram for describing a function providing system according to an exemplary embodiment.

[0081] Referring to FIG. 1, the function providing system according to the exemplary embodiment may include a mobile terminal 110, a first wearable device 120, and a second wearable device 130. The mobile terminal 110 according to the exemplary embodiment may provide a function of the mobile terminal 110 by using operations of the mobile terminal 110 and the wearable devices 120 and 130 according to connection states of the wearable devices 120 and 130 connected to the mobile terminal 110.

[0082] The term “function” as used herein may refer to an execution of at least one operation for achieving a specific objective. The execution of at least one operation for executing the function may refer to an execution of at least one sub-function for executing the function.

[0083] For example, the function as used herein may be executed by executing at least one sub-function for achieving a specific objective. For example, in a case where the execution of at least one operation is required for executing the function, the function may be executed by executing each sub-function for performing each operation.

Examples of the operation may include a communication operation, an information storage operation, an audio output operation, and a display operation. However, the exemplary embodiments are not limited thereto. The execution of each operation may refer to the execution of the sub-function of the function. A function type, a capability type, and an operation type for determining the function, the capability, and the operation may be determined in advance.

[0086] The function, the capability, and the operation will be described in more detail with reference to the call function. The mobile terminal 110, which executes the call function, may execute a communication operation of performing wireless communication with a base station by using a 2G, 3G, or 4G communication method, an audio output operation of providing a user with received audio data as audio information by using a speaker, and an audio input operation of generating voice data by recording a voice of a user from a microphone, as executions of a plurality of sub-functions for executing the call function. In addition, the mobile terminal 110 may perform the call function by performing an operation of providing a user interface (UI).

[0087] The function, the capability, and the operation of the privacy protection function will now be described.

[0088] The capability of a device may be determined according to the operation type of the device, based on whether the corresponding device has a specific capability. For example, if an earphone is capable of performing an audio output operation, the device may be determined as having an audio output capability. If the earphone further includes a microphone and is capable of performing an audio input operation by executing audio recording, the device may be determined as having an audio input capability. If the earphone is capable of performing a Bluetooth communication operation, the device may be determined as having a wireless communication capability.

[0089] For example, the device may perform the operation according to the capability thereof. The device may execute a specific function by performing at least one operation.

[0090] For example, the mobile terminal 110 may execute the call function. The mobile terminal 110 may execute the call function by performing the communication operation, the audio output operation, and the audio input operation. In this example, the mobile terminal 110 may include the communication capability, the audio output capability, and the audio input capability so as to execute the call function. For example, the call function may include an audio input operation performed by using a microphone having the audio input capability, an audio output operation performed by using a speaker having the audio output capability, and a communication operation performed by using a communication unit having the communication capability.

[0091] The mobile terminal 110 according to the exemplary embodiment may provide the function of the mobile terminal 110 by using operations performed by a plurality of wearable devices connected to the mobile terminal 110. The mobile terminal 110 according to the exemplary embodiment may determine whether the plurality of wearable devices are connected to the mobile terminal 110. The mobile terminal 110 according to the exemplary embodiment may acquire, from the wearable device, information about operations that may be performed by the wearable device connected to the mobile terminal 110. Alternatively, the mobile terminal 110 according to the exemplary embodiment may previously store, in a memory, information about operations that may be performed by the wearable device connected to the mobile terminal 110. The mobile terminal 110 may determine whether the wearable device is capable of performing the operation, and execute the function of the mobile terminal 110 by interworking with the operations of the wearable devices connected to the mobile terminal 110.

[0092] The mobile terminal 110 according to the exemplary embodiment may execute the connection to at least one wearable device. The mobile terminal 110 may transmit and receive data by executing the connection to at least one wearable device. The mobile terminal 110 may be a portable terminal such as a smart phone and a tablet personal computer (PC), a stationary terminal such as a desktop PC, or a repeater such as a home network server. However, the exemplary embodiments are not limited thereto.

[0093] The mobile terminal 110 may identify a wearable device connected thereto. The mobile terminal 110 may generate capability information, that is, information about operations that may be performed by the wearable device connected thereto. For example, the mobile terminal 110 may receive, from the wearable device, information about operations that may be performed by the wearable device connected thereto. The mobile terminal 110 may receive the capability information about the wearable device from the wearable device and store the capability information about the wearable device in a storage. The mobile terminal 110 may include at least one of a memory and a database as the storage. Alternatively, the mobile terminal 110 may prestore capability information about some wearable devices. For example, the mobile terminal 110 may prestore capability information about wearable devices, released by the same company, in the storage. Alternatively, the mobile terminal 110 may receive information about operations that may be performed by the wearable device from the wearable device or an external device (for example, a PC or a server), instead of prestoring the capability information. For example, when the mobile terminal 110 is connected to the wearable device, the mobile terminal 110 may receive, from the wearable device, capability information about the wearable device connected thereto. Various situations or conditions in which the mobile terminal 110 receives the capability information about the wearable device will be described below in detail with reference to exemplary embodiments.

[0094] The capability information about the wearable device, which is stored in the storage, may be updated. For example, in a case where the mobile terminal 110 receives new capability information in such a state that the mobile terminal 110 stores the capability information, the mobile terminal 110 may update the prestored capability information. In order to update the capability information, the mobile terminal 110 may request the capability information from the wearable device when the mobile terminal 110 is connected to the wearable device, or may periodically request the capability information from the wearable device after the mobile terminal 110 is connected to the wearable device. Alternatively, upon occurrence of an event such as a user input, the mobile terminal 110 may request the capability information from the wearable device. In order to update the capability information, the mobile terminal 110 may request the capability information from an external device, such as a PC or a server.

[0095] In a case where the capability information about the wearable device is updated, all of the capability information about the operations that may be performed by the wearable device may be received and updated, or only the capability information about the wearable device corresponding to a specific function of the mobile terminal may be received and updated. Alternatively, only the information changed in the prestored capability information about the mobile terminal 100 may be partially updated.

[0096] The updating of the capability information may be managed with version information. For example, the mobile terminal 110 may compare the version information of the prestored capability information with the version information of the new capability information for updating and perform updating when the version information of the new capability information is later than the version information of the prestored capability information. The magnitudes of the capabilities may be compared by comparing the operation performance. The performance at which the wearable device performs a specific operation may be expressed with performance information. The magnitudes of the capabilities may be compared by using the performance information. As described above, the performance at which the wearable device performs a specific operation may be managed with the performance information. The performance information may be prestored in the wearable device, or the performance information measured by the wearable device may be stored. Alternatively, the mobile terminal 110 may receive the performance information about the wearable device from the wearable device and store and mange the performance information about the wearable device. The performance information may be managed in a state of being included in the capability information. The performance information may be updated. For example, in a case where the mobile terminal 110 receives new performance information in such a state that the mobile terminal 110 stores the capability information, the mobile terminal 110 may update the prestored performance information. In order to update the performance information, the mobile terminal 110 may request the wearable device for the performance information when the mobile terminal 110 is connected to the wearable device, or may periodically request the wearable device for the performance information after the mobile terminal 110 is connected to the wearable device. Alternatively, upon occurrence of an event such as a user input, the mobile terminal 110 may request the wearable device for the performance information. In order to update the performance information, the mobile terminal 110 may request the external device, such as a PC or a server, for the performance information.

[0097] An example of comparing the magnitudes of the capabilities by using the performance information will be described below. For example, when data transmission performance information about the first wearable device 120, which performs a wireless communication operation by using an orthogonal frequency division multiplexing (OFDM) communication method, has a greater value than data transmission performance information about the second wearable device 130, which performs a wireless communication operation by using a code division multiple access (CDMA) communication method, it may be determined that the data transmission performance of the first wearable device 120 is higher than the data transmission performance of the second wearable device. In this manner, the mobile terminal 110 may compare the data transmission performance information about the first and second wearable devices 120 and 130 and determine that the data transmission capability of the first wearable device 120 is relatively higher than the data transmission capability of the second wearable device 130. In addition, the mobile terminal 110 may determine that the wireless communication capability including the data transmission capability is relatively higher in the first wearable device 120 than in the second wearable device 130.

[0098] The performance information may be expressed by using a commonly used unit according to a capability type. Accordingly, the magnitudes of the capabilities may be numerically compared with each other. For example, the wireless communication capabilities may be compared with each other based on a bit rate per second. The mobile terminal 110 may determine whether to use the operation of the wearable device according to a connection state of the wearable device connected thereto. For example, when the wearable device is disconnected from the mobile terminal 110, the mobile terminal 110 may determine not to use the operation of the wearable device.

[0099] The mobile terminal 110 may determine whether to use the operation of the wearable device according to a setting state of the wearable device connected thereto. For example, the wearable device may be set such that the control from other devices is not allowed. In this case, the mobile terminal 110 may not control the corresponding wearable device. Therefore, the mobile terminal 110 may determine not to use the operation of the corresponding wearable device.

[0100] The first wearable device 120 and the second wearable device 130, according to an exemplary embodiment, may be devices that are connected to the mobile terminal 110 to transmit data to the mobile terminal 110 and receive data from the mobile terminal 110. The wearable device may refer to a device used while being worn on or attached to the user's body. However, the exemplary embodiments are not limited thereto. The first wearable device 120 and the second wearable device 130 may be devices that operate at positions spaced apart from the user's body.

[0101] The first wearable device 120 and the second wearable device 130, according to an exemplary embodiment, may be connected to the mobile terminal 110 via a wired or wireless network. For example, the first wearable device 120 and the second wearable device 130 may be connected to the mobile terminal 110 via the same network. According to another exemplary embodiment, the first wearable device 120 and the second wearable device 130 may be connected to the mobile terminal 110 via different networks.

[0102] The first wearable device 120 and the second wearable device 130, according to an exemplary embodiment, may provide the mobile terminal 110 with executable operation information thereof and/or capability information thereof. The first wearable device 120 and the second wearable device 130, according to an exemplary embodiment, may perform the relevant operations in response to an operation execution request from the mobile terminal 110.

[0103] FIG. 2 is a flowchart of the operation of the function providing system, according to an exemplary embodiment. In operation S222, a mobile terminal 220 may generate mapping information about a plurality of wearable devices. The mapping information may be information indicating a wearable device that performs an operation required when a specific function is executed. For example, the mapping information may indicate an operation required when a specific function is executed.

For example, the mapping information may indicate that a request to execute a specific operation is to be transmitted to a specific device. The mapping information may include information about which operation is performed by a specific device used for executing a specific function.

[0104] For example, in order to execute the call function, the mobile terminal 220 may set the mapping information as follows. The mapping information may indicate that an audio output operation is performed by using an earphone from among wearable devices. The mapping information may indicate that an audio output request and audio data are to be transmitted to the earphone from among the wearable devices. The mapping information may indicate that an audio input operation is performed by using a microphone from among the wearable devices. The mapping information may indicate that an audio input request is to be transmitted to the microphone from among the wearable devices. The microphone may be provided inside the earphone. The mapping information may indicate that a UI provided to the user so as to execute the call function is provided to a smart watch. The mapping information may indicate that UI data and a request to execute the UI provided to the user so as to execute the call function should be transmitted to the smart watch.

[0105] According to another exemplary embodiment, in order to execute the privacy protection function, the mobile terminal 220 may set the mapping information as follows. The mapping information may indicate that a UI provided to the user so as to execute the privacy protection function is provided to the smart watch. The mapping information may indicate that UI data and a request to execute the UI provided to the user so as to execute the privacy protection function should be transmitted to the smart watch. When the information to be provided to the user is private information, the mobile terminal 220 may provide the information in the form of auditory information through the earphone. When the information to be transmitted to the user is not private information, the mobile terminal 220 may provide the information in the form of visual information through the smart watch. In order for the mobile terminal 220 to provide such information to the user, the mapping information may indicate that the auditory information is to be provided through the earphone from among the wearable devices and the visual information is to be provided to the smart watch from among the wearable devices. The mobile terminal 220 may use the mapping information to determine to which wearable device the auditory information is to be provided and to which wearable device the visual information is to be provided.

[0106] According to another exemplary embodiment, in order to execute the music playback function, the mobile terminal 220 may set the mapping information as follows. The mapping information may indicate that an audio output operation is performed by using the earphone from among the wearable devices. The mapping information may indicate that an audio output request and music audio data are to be transmitted to the earphone from among the wearable devices. The mapping information may indicate that a UI provided to the user so as to execute the music playback function is provided to the smart watch. The mapping information may indicate that UI data and a request to execute the UI provided to the user so as to execute the music playback function should be transmitted to the smart watch.

[0107] The mobile terminal 220 may prestore mapping information about at least one wearable device in a memory. Alternatively, when the wearable devices are connected to the mobile terminal 220, the mobile terminal 220 may generate mapping information about operations performed by the wearable devices through a communication method or a communication module by which the wearable devices are connected. Alternatively, the mobile terminal 220 may download capability information about at least one wearable device from the external device, such as a PC or a server, or may directly receive capability information about at least one wearable device from the corresponding wearable device. The mapping information may be periodically updated. For example, in a case where the mobile terminal 220 receives new mapping information in such a state that the mobile terminal 220 stores the mapping information, the mobile terminal 220 may update the prestored mapping information. In order to update the mapping information, the mobile terminal 220 may request the mapping information from the wearable device when the mobile terminal 110 is connected to the wearable device, or may periodically request the mapping information from the wearable device after the mobile terminal 110 is connected to the wearable device. Alternatively, upon occurrence of an event such as a user input, the mobile terminal 110 may request the mapping information from the wearable device. In order to update the mapping information, the mobile terminal 110 may request the mapping information from an external device, such as a PC or a server.

[0108] In operation S224, the mobile terminal 220 may check the connection of the wearable device based on the mapping information. The mobile terminal 220 may check whether the wearable device having been connected to the mobile terminal 220 still maintains the connection to the mobile terminal 220, based on the mapping information. For example, the mobile terminal 220 may check whether the mobile terminal 220 is connected to the wearable device designated in the mapping information, with reference to the mapping information, so as to execute the call function. For example, the mobile terminal 220 may check whether the earphone for audio output is connected to the mobile terminal 220, with reference to the mapping information. The mobile terminal 220 may be connected to the earphone by using a wireless communication method, such as Bluetooth or ZigBee. For example, the mobile terminal 220 may check whether the smart watch for providing a UI is connected to the mobile terminal 220, with reference to the mapping information. The mobile terminal 220 may be connected to the smart watch by using a wireless communication method, such as Bluetooth or ZigBee.

[0109] In operation S226, the mobile terminal 220 may transmit a first operation execution request to the first wearable device 210. The mobile terminal 220 may transmit the first operation execution request to the operation executing subject determined based on the mapping information.

[0110] For example, the mobile terminal 220 may transmit the operation execution request to the wearable device designated in the mapping information, with reference to the mapping information, so as to execute the call function. For example, when the first operation is the audio output operation, the mobile terminal 220 may transmit audio data and a request to execute the audio output operation to the earphone, with reference to the mapping information, so as to output audio data. Alternatively, when the first operation is the UI providing operation, the mobile terminal 220 may transmit UI data and a request to provide the UI to the smart watch, with reference to the mapping information, so as to provide the UI.

[0111] In operation S212, the first wearable device 210 may perform the first operation. The first wearable device 210 may perform the first operation in response to the first operation execution request received from the mobile terminal 220. The first wearable device 210 may generate a first operation execution result as a result of performing the first operation. The first operation execution result may be an output generated when the first wearable device 210 performs the first operation and may be generated as many different types of output information. For example, the first wearable device 210 may perform the first operation to output audio data, output a vibration, display a screen, or generate data-processing result data. The output generated by the first wearable device 210 is not limited to the above examples. Optionally, the first wearable device 210 may transmit the first operation execution result to the mobile terminal 220. The first wearable device 210 may transmit result data, which is generated as the first operation execution result, to the mobile terminal 220.

[0112] In operation S228, the mobile terminal 220 may transmit a second operation execution request to the second wearable device 230. The mobile terminal 220 may transmit the second operation execution request to the second wearable device 230 by using the mapping information. The second operation execution request may be transmitted before the first wearable device performs the first operation, may be transmitted at the same time as the execution of the first operation, or may be transmitted after the execution of the first operation is completed.

[0113] The mobile terminal 220 may transmit the second operation execution request to the second wearable device 230 such that the second operation to be performed at the same time as the operation of the first wearable device is performed by the second wearable device so as to execute the function of the mobile terminal 220. The execution of the first operation and the second operation at the same time is not limited to the simultaneous execution of the first and second operations, and may alternatively refer to both the first operation and the second operation being performed within a certain time frame of each other so as to execute the function of the mobile terminal 220.

[0114] The mobile terminal 220 may transmit the second operation execution request to the operation executing subject determined based on the mapping information. For example, when the second operation is the audio output operation, the second operation execution request may be transmitted to the second wearable device capable of performing the audio output operation based on the mapping information.

[0115] In operation S232, the second wearable device 230 may perform the second operation. The second wearable device 230 may perform the second operation in response to the second operation execution request received from the mobile terminal 220.

[0116] FIG. 3 is a flowchart of the operation of the mobile terminal 220, according to an exemplary embodiment. In operation S310, the mobile terminal 220 according to the exemplary embodiment may generate mapping information about operations for executing the function of the mobile terminal 220 and wearable devices that are to execute the operations.

[0117] As described above, the function may include at least one operation. In addition, the operation may be stereotyped according to the capability. The mapping information may indicate which operation is capable of being performed by the wearable device connected to the mobile terminal 220. Furthermore, the mapping information may indicate whether the wearable device is connected to the mobile terminal 220.

[0118] As described above, the mobile terminal 220 may prestore the mapping information about at least one wearable device in the memory. When the wearable device is connected to the mobile terminal 220, the mobile terminal 220 may store, in the memory, information about a communication method or a communication module by which the wearable device is connected to the mobile terminal 220 and generate the mapping information about the operations performed by the wearable device. Alternatively, the mobile terminal 220 may generate the mapping information by downloading capability information about at least one wearable device from the external device, such as a PC or a server, or by directly receiving capability information about at least one wearable device from the corresponding wearable device and storing the received capability information in the memory. The memory may include any type of storage medium. Examples of the memory may include a volatile memory and a non-volatile memory. The memory may include a disk-shaped storage medium.

[0119] In operation S320, the mobile terminal 220 may check the connection of the first wearable device 210 and the second wearable device 230, which are to perform the relevant operations, by using the mapping information stored in the memory. The connection may refer to a connection by which two different devices perform communication and are in a data transmittable or receivable state. The connection may include a connection via a wireless communication and/or a wired communication.

[0120] The mobile terminal 220 may transmit information to the first wearable device 210. The type of the transmitted information is not limited to any particular type. More specifically, in operation S330, the mobile terminal 220 may determine whether the second wearable device 230 is connected thereto.

[0121] The mobile terminal 220 may determine whether the second wearable device 230 is connected to the mobile terminal 220, by using connection information about the second wearable device 230 which is included in the mapping information. For example, in a case where the mapping information indicates that the second wearable device 230 is connected to the mobile terminal 220, the mobile terminal 220 may determine that the second wearable device 230 is connected thereto. In a case where the mapping information indicates that the second wearable device 230 is not connected to the mobile terminal 220, the mobile terminal 220 may determine that the second wearable device 230 is not connected thereto.

[0122] Alternatively, in order to determine whether the second wearable device 230 is connected to the mobile terminal 220 so as to perform a specific operation, the mobile terminal 220 may use the mapping information to determine whether the second wearable device 230 connected thereto is present with respect to a specific communication module or a specific communication method.

[0123] In a case where a specific wearable device is connected with respect to the specific communication module or the specific output method, the mapping information may store information about the connected specific wearable device with respect to the specific communication module or the specific output method.

[0124] Alternatively, in order to determine whether the second wearable device 230 is connected to the mobile terminal 220 so as to perform a specific operation, the mobile terminal 220 may use the mapping information to determine whether the second wearable device 230 capable of performing the specific operation is present. The mapping information may include information about the wearable device capable of performing the operation. In a case where a specific wearable device is connected, the mapping information may store information about whether the specific wearable device is connected.

[0125] In operation S340, when the second wearable device 230 is connected to the mobile terminal 220, the mobile terminal 220 may transmit, to the first wearable device 210, information for performing an operation that is performed together with an operation to be performed by the second wearable device so as to execute the function of the mobile terminal 220.

[0126] The mobile terminal 220 may distribute operations, which are to be performed so as to execute the function of the mobile terminal 220, to the wearable devices connected to the mobile terminal 220.

[0127] For example, in order to execute the call function, the mobile terminal 220 may distribute a video output operation to the first wearable device 210 having a video output capability and distribute an audio input or output operation to the second wearable device 230 having an audio input or output capability.

[0128] As described above, the feature of the operations being performed at the same time may refer to the executions of the respective operations being concurrently performed so as to execute the function of the mobile terminal 220. A specific associative relation, a specific relative relation, or a specific anteroposterior relation may exist between the respective operations. For example, whether to perform the second operation may be determined according to the execution result of the first operation, or the method of performing the second operation may be changed according to the execution result of the first operation. Therefore, the first operation and the second operation may be performed in association with each other. Since the second operation may be performed at the same time as the first operation or may be performed before or after the first operation, the first operation and the second operation may have an anteroposterior relation. Alternatively, the second operation may be performed by an identical or similar operation to the first operation, or the second operation may be performed in association with the identical or similar operation. However, the above-described relations may not exist between the operations.

[0129] In operation S350, when the second wearable device 230 is not connected to the mobile terminal 220, the mobile terminal 220 may transmit, to the first wearable device 210, information for performing an operation that is performed without an operation of the second wearable device so as to execute the function of the mobile terminal 220. In a case where a plurality of wearable devices are not connected or the operation cannot be distributed to the plurality of wearable devices, the mobile terminal 220 may distribute the operation to only one wearable device.

[0130] For example, in a case where the first wearable device 210 capable of performing the video output operation is connected, the mobile terminal 220 may transmit information for performing the video output operation to the first wearable device 210, while performing the audio input or output operation.

[0131] FIG. 4 is a flowchart of an operation of the first wearable device 210, according to an exemplary embodiment. The operation of the first wearable device 210, according to the exemplary embodiment, will be described with reference to FIG. 4.

[0132] In operation S412, the first mobile terminal 210 according to the exemplary embodiment may receive connection information from the mobile terminal 220. The connection information may be information indicating whether the wearable devices that are to perform operations for executing the function of the mobile terminal 220 are connected to the mobile terminal 220.

[0133] In operation S414, the first wearable device 210 may determine whether the second wearable device 230 is connected to the mobile terminal 220, based on the connection information about the wearable devices that is received from the mobile terminal 220. When the connection information about the wearable devices that is received from the mobile terminal 220 indicates that the second wearable device 230 is connected to the mobile terminal 220, the first wearable device 210 may determine that the second wearable device 230 is connected to the mobile terminal 220.

[0134] In operation S416, when the second wearable device 230 is connected to the mobile terminal 220, the first wearable device 210 may perform an operation that is performed together with an operation to be performed by the second wearable device 230 so as to execute the function of the mobile terminal 220.

[0135] In operation S418, when the second wearable device 230 is not connected to the mobile terminal 220, the first wearable device 210 may perform an operation that is performed without the operation of the second wearable device 230 so as to execute the function of the mobile terminal 220.

A communication method between the smart phone 520 and the smart watch 510 may be equal to or different from a communication method between the smart phone 520 and the earphone 530. For example, the smart phone 520 may communicate with the smart watch 510 through a Bluetooth connection, and the smart phone 520 may communicate with the earphone 530 through a wired connection. Alternatively, the smart phone 520 may communicate with the earphone 530 through Bluetooth connection.

[0147] The smart phone 520 may transmit output audio data to the earphone according to the UI control result data received from the smart watch 510. The output audio data may be audio data of other users that the smart phone 520 receives from a base station or other terminal. The smart watch 510 may transmit, to the smart phone 520, control data generated by the UI operation of the user. The smart phone 520 may determine whether to transmit the output audio data to the earphone 530 by using the control data received from the smart phone 520. In operation S532, the earphone 530 may output the audio by using the audio output data. In operation S532, the earphone 530 may receive the audio of the user and output audio data. In operation 534, the earphone 530 may transmit the received audio data to the smart phone 520. The smart phone 520 may perform the call function by transmitting the audio data received from the earphone 530 to the base station or other terminal.

[0148] FIG. 7 is a flowchart of a method by which an earphone 530 provides a UI to a smart watch 510, according to an exemplary embodiment. An operation execution request transmitted from a mobile terminal to a first wearable device may be changed according to a connection state of a second wearable device, and the operation of the second wearable device may not be performed. For example, the UI provided through the smart watch 510 in operation S582 of FIG. 6 may be changed according to the connection state of the earphone 530, and operation 584 may not be performed. Details will be described below with reference to FIG. 7.

[0149] In operation S710, the smart phone 520 according to the exemplary embodiment may determine whether the earphone 530 is connected thereto. In operation S720, when the earphone 530 is connected to the smart phone 520, the smart phone 520 may transmit a call connection UI to the smart watch 510. In operation S730, when the earphone 530 is not connected to the smart phone 520, the smart phone 520 may provide a call notification UI to the smart watch 510. The call notification UI is an alternative UI that is provided when it is impossible or difficult to provide a UI for controlling the function of the mobile terminal such as the smart phone 520. The mobile terminal may provide the wearable device with information indicating that it is impossible or difficult to provide a control UI. Alternatively, the mobile terminal 110 may provide no UI when it is impossible or difficult to provide an operation control UI.

[0150] FIG. 8 is a conceptual diagram for describing a notification UI provided in the method of providing the call function, according to an exemplary embodiment.

[0151] The notification UI, which is provided from the smart phone 520 to the smart watch 510, may be a UI that notifies a reception of a call acceptance request. The notification UI, which is provided to the smart watch 510 as illustrated in FIG. 8, may be a UI that displays a phone number of a caller while notifying a reception of a phone call.

[0152] FIG. 9 is a conceptual diagram for describing a notification UI provided in the method of providing the call function, according to another exemplary embodiment.

[0154] FIGS. 10 to 13 are diagrams for describing a call connection UI according to an exemplary embodiment. FIG. 10 is a flowchart for describing the call connection UI according to an exemplary embodiment. In operation S1010, the call connection UI may display a call acceptance object and a call decline object.

[0155] The call connection UI will be described below in more detail with reference to FIG. 11. FIG. 11 is a conceptual diagram for describing the call connection UI according to the exemplary embodiment.

[0156] A smart phone 520 according to an exemplary embodiment may be connected to an earphone 530 and a smart watch 510. When it is possible to control the operations of the earphone 530 and the smart watch 510, the smart phone 520 may perform the operations of the earphone 530 and the smart watch 510 and execute the call function.

[0157] When it is possible to control the operations of the earphone 530 and the smart watch 510, the smart phone 520 may provide the call connection UI to the smart watch 510. The smart watch 510 may provide the user with the call connection UI by using UI data provided from the smart phone 520.

[0158] As illustrated in FIG. 11, the call connection UI, which is provided to the smart watch 510, may include a caller number display object 1110, a call acceptance control object 1120, and a call decline/message transfer object 1130. These objects 1110, 1120, and 1130, which are included in the call connection UI described with reference to FIG. 11, are merely exemplary, and the types and the number of the objects 1110, 1120, and 1130 displayed on the call connection UI are not limited thereto.

[0159] The caller number display object 1110 may display a phone number or other identifying information of a caller. The call acceptance control object 1120 may be an object that receives a call acceptance input from a user by receiving a user input, such as a touch or input from a pointing device that is input to a corresponding object. The call decline/message transfer object 1130 may be an object that receives a call decline input or a message transfer input from a user by receiving a user input, such as a touch or input from a pointing device that is input to a corresponding object.

[0160] The smart watch 510 may generate the call acceptance input when the user touches the call acceptance object 1120 displayed on the smart watch 510. The smart watch 510 may transmit the call acceptance input to the smart phone 520.

[0161] Similarly, the smart watch 510 may generate the call decline input when the user touches the call decline/message transfer object 1130 displayed on the smart watch 510. The smart watch 510 may transmit the call decline input to the smart phone 520.

[0162] Referring again to FIG. 10, in operation S1020, the call connection UI may confirm whether the call acceptance input is received from the user. In operation S1030, the call connection UI may display a busy UI when the call acceptance input is received from the user. The busy UI will be described below in detail with reference to FIG. 12.

[0163] FIG. 12 is a conceptual diagram for describing the busy UI according to an exemplary embodiment.

[0164] A smart phone 520 may be connected to an earphone 530 and a smart watch 510. When the smart phone 520 performs the operations of the earphone 530 and the smart watch 510 and executes the call function of the smart phone 520, the smart phone 520 may provide the busy UI to the smart watch 510. The smart watch 510 may provide the user with the busy UI by using UI data received from the smart phone 520.

[0165] As illustrated in FIG. 12, the busy UI, which is provided to the smart watch 510, may include a caller number display object 1210, a call time display object 1220, an audio increase control object 1230, an audio decrease control object 1240, and a call end object 1250. These objects 1210, 1220, 1230, 1240, and 1250 are merely exemplary, and the types and the number of the objects 1210, 1220, 1230, 1240, and 1250 displayed on the busy UI are not limited thereto.

[0166] The smart watch 510 may perform control according to the objects when a user input is received through the audio increase control object 1230, the audio decrease control object 1240, and the call end object 1250. For example, when the user input is input through the audio increase control object 1230, the smart watch 510 may raise an audio volume.

[0167] Referring again to FIG. 10, in operation S1040, when the call acceptance input is not received from the user, the call connection UI may confirm whether the call decline input is received from the user. In operation S1050, the call connection UI may display a call decline UI when the call decline input is received from the user. When both the call acceptance input and the call decline input are not received, the call connection UI may confirm whether the call acceptance input or the call decline input is input again.

[0168] The call decline UI will be described below in more detail with reference to FIG. 13. FIG. 13 is a conceptual diagram for describing the call decline UI according to the exemplary embodiment.

[0169] A smart phone 520 according to an exemplary embodiment may be connected to an earphone 530 and a smart watch 510. When it is possible to execute the call function by using the operations of the earphone 530 and the smart watch 510, the smart phone 520 may provide the call decline UI to the smart watch 510. The smart watch 510 may provide the user with the call decline UI by using UI data received from the smart phone 520.

[0170] The call decline UI may include a caller number display object, a message transfer control object, and a call decline control object. When a user input of selecting the message transfer control object is generated, the smart watch 510 may transmit a message transfer request to the smart phone 520 so as to transfer a message to a caller. The smart watch 510 may display a list of messages to be transferred to a user and receive a user selection.

[0171] When a user input of selecting the call decline control object is generated, the smart watch 510 may transmit a call decline request to the smart phone 520.

[0172] A method by which the mobile terminal 110 according to the exemplary embodiment transmits operation execution requests to the first and second wearable devices 120 and 130 will be described below in detail. FIGS. 14 to 19 are conceptual diagrams for describing a method by a smart phone 520 as the mobile terminal 110 transmits operation execution requests to a smart watch 510 as the first wearable device 120 and an earphone 530 as the second wearable device 130, according to an exemplary embodiment. Assuming that the mobile terminal 110, the first wearable device 120, and the second wearable device 130 are the smart phone 520, the smart watch 510, and the earphone 530, respectively, the operations of the mobile terminal 110, the first wearable device 120, and the second wearable device 130 will be described below.

[0173] FIG. 14 is a flowchart of a method by which the mobile terminal 110 transmits the operation execution requests to the first and second wearable devices 120 and 130, according to an exemplary embodiment. As illustrated in FIG. 14, the smart phone 520 may transmit a first operation execution request 1421 to the smart watch 510 and transmit a second operation execution request 1422 to the earphone 530. The smart phone 520 may transmit the first operation execution request and the second operation execution request to the first and second wearable devices 510 and 530 at the same time or at different times.

[0174] FIGS. 15 to 17 are conceptual diagrams for describing a communication method between the mobile terminal 110 and the first and second wearable devices 120 and 130, according to exemplary embodiments.

[0175] FIG. 15 is a conceptual diagram for describing a communication method between the mobile terminal 110 and the first and second wearable devices 120 and 130, according to an exemplary embodiment. The mobile terminal 110 according to the exemplary embodiment may transmit data to and receive data from the first wearable device 120 and the second wearable device 130 by using the same communication method or different communication methods.

[0176] Referring to FIG. 15, the smart phone 520 according to the exemplary embodiment may communicate with the smart watch 510 via a wireless network 1521 and communicate with the earphone 530 via a wired network 1522. This is merely exemplary and the communication method between the smart phone 520 and the first and second wearable devices 510 and 530 is not limited thereto. For example, the smart phone 520 may communicate with the smart watch 510 via a wired network and communicate with the earphone 530 via a wireless network. Alternatively, the smart phone 520 may communicate with both the smart watch 510 and the earphone 530 via a wired network or a wireless network.

[0177] For example, referring to FIG. 16, the smart phone 520 may transmit data to and receive data from the smart watch 510 and the earphone 530 by using Bluetooth communications 1621 and 1622. Referring to FIG. 17, the smart phone 520 may transmit data to and receive data from the smart watch 510 by using a Wi-Fi connection 1721 and transmit data to and receive data from the earphone 530 by using a Bluetooth connection 1722.

[0178] FIG. 18 is a diagram illustrating an example in which the smart phone 520 according to an exemplary embodiment transmits operation execution requests and data related to operation execution to the first and second wearable devices 510 and 530. The smart phone 520 according to an exemplary embodiment may transmit the operation execution requests and the data related to the operation execution to the first and second wearable devices 510 and 530.

For example, when a screen output signal or output data is generated during the execution of the function, the mobile terminal 220 may recognize a situation that an operation requiring a display capability may be occurring. The mobile terminal 220 may recognize that it may be necessary to perform an operation requiring a specific capability by using a signal or data generated during the execution of the call function.

[0256] FIG. 43 is a conceptual diagram for describing a method of finding a wearable device having capacity to execute an operation by using capability information about wearable devices that is stored in the mobile terminal 220.

[0262] In operation S4510, the mobile terminal 220 may search for a wearable device that has a capability corresponding to the capability information about the operations. The mobile terminal 220 may end the searching for additional wearable devices when a wearable device having the required capability is found during the retrieval of the capability information about the wearable devices. On the other hand, the mobile terminal 220 may continue to search for the wearable device having the required capability even when the wearable device having the required capability is found.

[0263] In operation S4520, the mobile terminal 220 may select a wearable device that is to perform the operation, taking into consideration hardware performance of the found wearable devices.

[0266] In FIG. 47, the mobile terminal 220 may know that the second wearable device 230 does not have the display capability by retrieving the capability information about the second wearable device 230. The mobile terminal 220 may retrieve the capability information about a next wearable device, without separately processing capability information about the second wearable device 230.

[0267] In FIG. 48, as a result of sequentially retrieving capability information about the wearable devices, the mobile terminal 220 may retrieve capability information about the K-th wearable device. The mobile terminal 220 may confirm that the display capability is included in the capability information about the K-th wearable device and determine that the K-th wearable device has the display capability.

[0268] Lastly, as illustrated in FIG. 49, the mobile terminal 220 may determine the first wearable device 210 and the K-th wearable device as the wearable devices having the display capability.

[0269] FIGS. 50 to 52 are diagrams for describing a method by which the mobile terminal 220 compares hardware performances of wearable devices, according to exemplary embodiments.

[0270] FIG. 50 is a conceptual diagram of a data structure of performance information about the wearable device that is stored in the memory of the mobile terminal 220, according to an exemplary embodiment. As illustrated in FIG. 50, the capability information about the wearable device may include hardware performance information and software performance information about the wearable device.

[0271] In the exemplary embodiment of FIG. 50, the first wearable device 210 and the K-th wearable device may include hardware performance and/or software performance with respect to a screen size, a provision resolution, processor performance, and memory performance in the case of the display capability. This list of types of performance is exemplary and the types of performances according to exemplary embodiments are not limited thereto.

[0272] The mobile terminal 220 may select a wearable device that is to perform the operation, taking into consideration performance for a specific capability. Alternatively, the mobile terminal 220 may select a wearable device that is to perform the operation, taking into consideration performances for a plurality of capabilities. For example, the mobile terminal 220 may calculate a performance score with respect to at least two capabilities and select a wearable device by using the calculated performance score. The mobile terminal 220 may apply different weights to different hardware performances

[0273] FIG. 51 is a conceptual diagram of a data structure in which the mobile terminal 220 stores minimum performance information in a memory with respect to minimum hardware performance required to have the capability, according to an exemplary embodiment.

[0274] The mobile terminal 220 according to an exemplary embodiment may store the minimum performance information in the memory with respect to the capability required for performing a specific operation. The minimum performance information may be determined with respect to a specific capability. The minimum performance information may be information indicating minimum performance required for the wearable device so as to perform a specific operation that the wearable device is requested to perform from the mobile terminal 220. The mobile terminal 220 according to an exemplary embodiment may determine the wearable device that is to perform the specific operation by using the minimum performance information. For example, the mobile terminal 220 according to an exemplary embodiment may determine the wearable device that is to perform the specific operation by using the minimum performance information stored in the mobile terminal 220 and the performance information about the wearable device that is acquired from the wearable device.

[0275] For example, even when there is a wearable device capable of performing the specific operation, the mobile terminal 220 according to an exemplary embodiment may compare the performance information about the wearable device with respect to the specific operation with the minimum performance information about the mobile terminal 220, and determine the corresponding wearable device as the wearable device that is to perform the specific operation only when the performance information about the wearable device satisfies the minimum performance.

[0276] The mobile terminal 220 according to an exemplary embodiment may determine the wearable device, which is to perform the specific operation, by transmitting, to the wearable device, the minimum performance information about the specific capability to perform the specific operation, and receiving, from the wearable device, whether the minimum performance is satisfied. According to another exemplary embodiment, the mobile terminal 220 according to an exemplary embodiment may determine the wearable device, which is to perform the specific operation, by receiving, from the wearable device, the performance information to perform the specific operation, and comparing the performance information received from the wearable device with the minimum performance information. For example, if the performance for the specific capability of the wearable device is equal to or higher than the minimum performance, the mobile terminal 220 and the wearable device may be determined as satisfying the minimum performance.

[0277] Details will be described below with reference to FIG. 51. As illustrated in FIG. 51, the mobile terminal 220 according to an exemplary embodiment may store the minimum performance information in the memory with respect to the display capability required for performing an information display operation. The minimum performance information may be determined with respect to a specific capability. The minimum performance information may be information indicating minimum performance required for the wearable device so as to perform a specific operation that the wearable device is requested to perform from the mobile terminal 220. For example, the minimum performance information about the display capability may be determined based on a screen size, a provision resolution, processor performance, or memory performance. Referring to FIG. 51, the provision resolution, which is minimally required for performing the information display operation, may be 320×240, although it is understood that the minimum provision resolution may be greater or less than 320×240 according to exemplary embodiments. Therefore, in the exemplary embodiment of FIG. 51, the minimum performance information about the provision resolution in the display capability is 320×240.

[0278] FIG. 52 is a conceptual diagram of a data structure in which hardware performances of wearable devices are stored in the memory of the mobile terminal 220, according to an exemplary embodiment.

[0279] As illustrated in FIG. 52, the maximum resolution at which the first wearable device 210 has the display capability is 220×80, and the maximum resolution at which the K-th wearable device is capable of executing the display capability is 1020×768.

[0280] The mobile terminal 220 may select the K-th wearable device, which is capable of providing a higher resolution than 320×240, that is, the minimum resolution of the display required for performing the information display operation, as the wearable device for performing the information display operation.

[0281] According to an exemplary embodiment, the mobile terminal 220 may select one wearable device, based on a preset criterion, when there are a plurality of wearable devices that provide a higher resolution than the minimum resolution of the display required for performing the information display operation. For example, the mobile terminal 220 may select a wearable device, the maximum resolution of which has the smallest difference from the required resolution of the display. Alternatively, the mobile terminal 220 may select a wearable device, the aspect ratio of which is substantially equal to the aspect ratio of the required resolution of the display.

[0282] FIG. 53 is a flowchart of a method by which the mobile terminal 220 selects a wearable device that is to perform an operation from among a plurality of wearable devices, according to another exemplary embodiment.

[0283] In operation S5310, the mobile terminal 220 may search for wearable devices that execute a capability corresponding to the capability information about operations.

In operation S5320, the mobile terminal 220 may select a wearable device that is to perform the operation, taking into consideration whether capabilities of found wearable devices are usable. The mobile terminal 220 may determine the wearable device that is to perform the operation, taking into consideration various factors, such as whether the user is enabled to recognize information provided from the wearable devices, whether the mobile terminal 220 is enabled to control the wearable devices, whether the user wears the wearable devices, and/or whether the mobile terminal 220 is enabled to display a notification to the user in a case where the mobile terminal 220 provides a UI. Hereinafter, the above-described situations will be described with reference to the accompanying drawings.

[0284] FIG. 54 is a flowchart of a method by which the mobile terminal 220 selects a wearable device that is to perform an operation from among a plurality of wearable devices, taking into consideration situation information, according to an exemplary embodiment. In operation S5411, the mobile terminal 220 may search for wearable devices that have a capability corresponding to capability information about operations.

[0285] In operation S5421, the mobile terminal 220 may select a wearable device that is to perform the operation, taking into consideration situation information about found wearable devices. The mobile terminal 220 may take into consideration wearing position information about the wearable devices as the situation information about the wearable devices. For example, the mobile terminal 220 may determine whether to display information around a wrist of the user or whether to display information in a user's field of vision and may determine whether to display information to the user through the smart watch or whether to display information to the user through the smart glass.

[0286] Alternatively, the mobile terminal 220 may take into consideration an environment where the wearable device is located. For example, the mobile terminal 220 may use luminous intensity input from an illuminance sensor to determine whether the user may not be able to instantly recognize the smart watch because the smart watch is covered with a collar. Alternatively, the mobile terminal 220 may use biometric information. When the wearable device measures biometric information, the mobile terminal 220 may determine that the user is wearing the corresponding wearable device and perform an information display operation by using the corresponding wearable device.

[0287] FIG. 55 is a diagram for describing a method by which the mobile terminal 220 stores situation information data of wearable devices in a memory, according to an exemplary embodiment. The mobile terminal 220 may store the situation information about the wearable devices with respect to each of the wearable device.

[0288] Referring to FIG. 55, a first wearable device 210 is a smart watch and a K-th wearable device is a smart glass. In the exemplary embodiment of FIG. 55, situation information about the first wearable device 210 and the K-th wearable device may include wearing positions, ambient brightness information, and wearing or non-wearing of the wearable devices.

[0289] For example, the mobile terminal 220 may use ambient brightness information among pieces of situation information about the first wearable device 210 and the K-th wearable device to determine a wearable device as a device that is to perform the information display operation, when the corresponding wearable device has ambient brightness of a preset illuminance or higher.

[0290] The acquiring of the situation information will be described below in more detail. The mobile terminal 220 may receive, from the first wearable device 210, basic information indicating that the first wearable device 210 is the smart watch, and acquire situation information indicating that the first wearable device 210 is worn on a wrist of the user.

[0291] In addition, the mobile terminal 220 may use a camera module of the first wearable device 210 to acquire ambient brightness information about the first wearable device 210. The mobile terminal 220 may use a heart rate measurement module of the first wearable device 210 to acquire information about whether the user wears the first wearable device 210 and may use a vibration module of the first wearable device 210 to confirm whether the user recognizes the first wearable device 210.

[0292] Similarly, the mobile terminal 220 may receive, from the K-th wearable device, basic information indicating whether the K-th wearable device is the smart glass, and acquire situation information indicating whether the K-th wearable device is worn on a face. The mobile terminal 220 may use a camera module of the K-th wearable device to acquire ambient brightness information about the K-th wearable device, information about whether the K-th wearable device is worn, and information about whether the user recognizes information displayed on the K-th wearable device. In addition, the mobile terminal 220 may acquire, from the K-th wearable device, information about whether an interference prohibition mode is set to the K-th wearable device and determine whether the mobile terminal 220 is capable of controlling the K-th wearable device under the current situation.

[0293] FIG. 56 is a flowchart of a method by which the mobile terminal 220 determines a device having a capability to perform an operation from among a plurality of devices, according to an exemplary embodiment.

[0294] In operation S5610, the mobile terminal 220 may check whether there are devices for which a determination as to whether the devices are usable has not been determined. If there are no devices for which a determination as to whether the devices are usable has not been determined, the mobile terminal 220 may determine that there is no usable device.

[0295] In operation S5620, the mobile terminal 220 may determine whether it is possible to control the first device in a list of devices for which a determination as to whether the devices are usable has not been determined. When a wearable device is in an uncontrollable state, the situation information may indicate that the corresponding wearable device is in the uncontrollable state. Alternatively, when the mobile terminal 220 transmits a response request to a wearable device and does not receive a response from the corresponding wearable device, the mobile terminal 220 may determine the corresponding wearable device as being in the uncontrollable state. Alternatively, when the mobile terminal 220 transmits a control request to a wearable device and does not receive a response from the corresponding wearable device, the mobile terminal 220 may determine the corresponding wearable device as being in the uncontrollable state.

[0296] In operation S5630, when it is possible to control the first device in the list of devices for which a determination as to whether the devices are usable has not been determined, the mobile terminal 220 may perform the operation by using the corresponding first device.

[0297] In operation S5640, when it is impossible to control the first device in the list of devices for which a determination as to whether the devices are usable has not been determined, the mobile terminal 220 may perform the operation by using another usable device. The mobile terminal 220 may re-determine usable devices with respect to other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined. For example, the mobile terminal 220 may perform operation S5610 and subsequent operations on the other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined.

[0298] FIGS. 57 and 58 are flowcharts of a method by which the mobile terminal 220 determines a device for performing an operation from among a plurality of devices, according to an exemplary embodiment.

[0299] Referring to FIG. 57, in operation S5710, the mobile terminal 220 may check whether there are devices for which a determination as to whether the devices are usable has not been determined, in a similar manner to the device determining method of FIG. 56, and determines a wearable device that is to perform the operation. In operation S5720, the mobile terminal 220 may determine a device that is to perform the operation, based on whether the wearable device is being worn.

[0300] In operation S5720, the mobile terminal 220 may determine whether the user is wearing the first device in the list of devices for which a determination as to whether the devices are usable has not been determined. For example, when a biometric signal measured by a wearable device has a value within a valid range, the mobile terminal 220 may determine that the corresponding wearable device is being worn.

[0301] When it is determined that the first wearable device is being worn, the mobile terminal 220 may determine the first wearable device as the usable device. In operation S5730, the mobile terminal 220 may perform the operation by using the usable first device. When it is determined that the first wearable device is not worn, the mobile terminal 220 may determine the first wearable device as an unusable device. In operation S5740, the mobile terminal 220 may perform the operation by using another of the usable wearable devices. The mobile terminal 220 may re-determine wearing or non-wearing with respect to other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined. For example, the mobile terminal 220 may perform operations S5710 and S5720 on the other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined, and perform operations S5730 or S5740 again.

[0302] Referring to FIG. 58, in a similar manner to the device determining method of FIG. 56, the mobile terminal 220 may determine a wearable device that is to perform the operation. In operation S5810, the mobile terminal 220 may check whether there is devices for which a determination as to whether the device are usable has not been determined. In operation S5820, the mobile terminal 220 may determine a device that is to perform the operation based on whether the wearable device is capable of displaying a notification.

[0303] In operation S5820, the mobile terminal 220 may determine whether the first device in the list of devices for which a determination as to whether the devices are usable has not been determined is capable of displaying a notification. For example, the mobile terminal 220 may retrieve the capability information about the wearable device and determine whether the corresponding wearable device has the information display capability.

[0304] When it is determined that the first wearable device is capable of displaying the notification, the mobile terminal 220 may determine the first wearable device as a usable device. In operation S5830, the mobile terminal 220 may perform the operation by using the first wearable device.

[0305] When it is determined that the first wearable device is incapable of displaying the notification, the mobile terminal 220 may determine the first wearable device as an unusable device. In operation S5840, the mobile terminal 220 may perform the required operation by using another usable wearable device. The mobile terminal 220 may re-determine whether other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined are capable of displaying the notification. For example, the mobile terminal 220 may perform operations S5810 and S5820 on the other devices except for the first device in the list of devices for which a determination as to whether the devices are usable has not been determined, and perform operations S5830 or S5840 again.

[0306] FIG. 59 is a flowchart of a method by which the mobile terminal 220 provides a UI to a wearable device, according to an exemplary embodiment.

[0307] In operation S5910, the mobile terminal 220 according to an exemplary embodiment may determine whether it is possible to distribute operations to a plurality of wearable devices.

[0308] In operation S5920, when it is determined that it is possible to distribute the operations to the plurality of wearable devices, the mobile terminal 220 may provide at least one of the wearable devices with an operation control UI.

[0309] In operation S5930, when it is determined that it is impossible (or difficult) to distribute the operations to the plurality of wearable devices, the mobile terminal 220 may simply provide a function notification UI.

[0310] The function notification UI is an alternative UI that is provided when it is impossible (or difficult) to provide the operation control UI. The mobile terminal 220 may provide the wearable device with information indicating that it is impossible (or difficult) to provide the operation control UI. Alternatively, the mobile terminal 220 may provide no UI when it is impossible (or difficult) to provide the operation control UI.

[0311] FIG. 60 is a flowchart of a method performed by a call function providing system to provide a call function, according to an exemplary embodiment.

In operation S6014, the smart watch 6010 may transmit UI control result data to the smart phone 6020. In operation S6029, the smart phone 6020 may transmit audio output data to an earphone 6030.

[0313] The smart phone 6020 may transmit output audio data to the earphone 6030 according to the UI control result data received from the smart watch 6010. The output audio data may be audio data of another user that the smart phone 6020 receives from a base station or other terminal. The smart watch 6010 may transmit, to the smart phone 6020, control data generated by the UI operation of the user. The smart phone 6020 may determine whether to transmit the output audio data to the earphone 6030 by using the control data received from the smart phone 6010. In operation S6029, the earphone 6030 may output the audio by using the audio output data. In operation S6032, the earphone 6030 may receive the audio of the user and generate audio data. The earphone 6030 may include a microphone and receive the audio of the user. In operation S6034, the earphone 6030 may transmit the received audio data to the smart phone 6020. The smart phone 6020 may perform the call function by transmitting the audio data received from the earphone 6030 to the base station or other terminal.

[0314] FIG. 61 is a flowchart of a method by which the smart phone 6020 determines a UI to be transmitted to the smart watch 6010 in the method of providing the call function, according to an exemplary embodiment.

[0315] Referring to FIG. 61, in operation S6110, the smart phone 6020 may determine whether both a wearable device having a capability to provide the UI and a wearable device having a capability to input and output audio exist.

[0316] When it is determined that both the wearable device having the capability to provide the UI and the wearable device having the capability to input and output audio exist, the smart phone 6020 may provide a call connection UI. For example, in operation S6120, the smart phone 6020 may provide the call connection UI to the wearable device having the capability to provide the UI.

[0317] In operation S6130, when it is determined that either of the wearable device having the capability to provide the UI and the wearable device having the capability to input and output audio does not exist, the smart phone 6020 may provide a notification UI to the existing wearable device. In operation S6130, when it is determined that both of the wearable device having the capability to provide the UI and the wearable device having the capability to input and output audio do not exist, the smart phone 6020 may provide the notification UI to the smart phone 6020.

[0318] The notification UI may be a UI that notifies information, and the type of the information is not limited to any particular type. For example, the notification UI may be a UI notifying that the smart phone 6020 has received a call acceptance request from a base station or other terminal. Alternatively, the notification UI may be a UI notifying that the connection of wearable devices required for providing the call function is insufficient.

[0319] FIGS. 62 to 64 are diagrams for describing a method of providing a private information displaying function, according to an exemplary embodiment.

[0320] As illustrated in FIGS. 62 to 64, the method of providing the private information displaying function, according to an exemplary embodiment, may be performed using a smart watch 6210, a smart phone 6220, and a smart glass 6230.

The smart watch 6210 may provide a privacy protection or non-protection query UI to the user and receive relevant input from the user. When an input of operating a privacy protection mode is received from the user, the smart watch 6210 may transmit a privacy protection mode ON message to the smart phone 6220. When the privacy protection mode ON message is received, the smart phone 6220 may transmit data, which is predefined as private data, to the smart glass 6230.

[0322] Referring to FIG. 63, when an input of not operating the privacy protection mode is received from the user, or when an input of operating the privacy protection mode is not received from the user, the smart watch 6210 may transmit a privacy protection mode OFF message to the smart phone 6220. When the privacy protection mode OFF message is received, the smart phone 6220 may transmit data, which is predefined as private data, to the smart watch 6210.

[0323] When an input of not operating the privacy protection mode is received from the user, or when an input of operating the privacy protection mode is not received from the user, the smart watch 6210 may not transmit a privacy protection mode message to the smart phone 6220. When the privacy protection mode message is not received within a preset time, the smart phone 6220 may transmit data, which is predefined as private data, to the smart watch 6210.

[0324] The method of providing the private information displaying function, according to an exemplary embodiment, will be described below with reference to FIG. 64.

[0325] In operation S6220, the smart phone 6220 may generate capability information about a plurality of wearable devices. In operation S6222, the smart phone 6220 may transmit privacy protection or non-protection query UI data to the smart watch 6210.

[0485] The communication unit 8510 may transmit, to the mobile terminal 8300, result data obtained by performing the operation according to the information for performing the operation. For example, the wearable device 8500 may transmit pulse information and temperature information to the mobile terminal 8300.

[0486] The processor 8530 may control an overall operation of the wearable device 8500. For example, the processor 8530 may control the output unit 8550, the user input unit 8540, the communication unit 8510, the sensing unit 8560, and the A/V input unit 8570 by executing the programs stored in the memory 8520.

[0487] Based on the information for performing the operation, the processor 8530 may control the communication unit 8510, the memory 8520, the user input unit 8540, the sensing unit 8560, and the A/V input unit 8570 to, when another wearable device is connected to the mobile terminal 8300, perform an operation that is performed together with an operation to be performed by the other wearable device so as to execute the function of the mobile terminal 8300 and, when another wearable device is not connected to the mobile terminal 8300, perform an operation that is performed, without the operation of the other wearable device, so as to execute the function of the mobile terminal 8300.

[0488] In addition, other exemplary embodiments can also be implemented through computer readable code or instructions in or on a medium, e.g., a computer readable medium, to control at least one processing element to implement any above described exemplary embodiment. The medium can correspond to any medium or type of media permitting the storage and/or transmission of the computer readable code.

[0489] The computer readable code can be recorded or transferred on a medium in a variety of ways, with examples of the medium including recording media, such as magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.) and optical recording media (e.g., CD-ROMs, or DVDs), and transmission media such as Internet transmission media. Thus, the medium may be such a defined and measurable structure including or carrying a signal or information, such as a device carrying a bitstream according to one or more exemplary embodiments. The media may also be a distributed network, so that the computer readable code is stored or transferred and executed in a distributed fashion. Furthermore, the processing element could include a processor or a computer processor, and processing elements may be distributed and/or included in a single device.
