Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Oct. 30, 2014 in the Korean Intellectual Property Office and assigned Serial number No. 10-2014-0149227, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method of communicating with an external electronic device selected from a group, which is formed using an ad hoc network, based on a motion of the electronic device or a voice signal and an electronic device for supporting the same.

BACKGROUND

An electronic device may form a group with an external electronic device and communicate with another electronic device within the group. A representative example of the communication is push-to-talk (PTT) group communication. The PTT group communication is a unidirectional service in which only a user having an opportunity to transmit a voice signal among users included in the group can transmit the voice signal to a counterpart. When a particular user transmits a voice signal by pressing a button for transmitting the voice signal, the remaining users may receive the voice signal from the particular user while they do not press the button. The PTT group communication is provided to immediately transmit the voice signal between the users included in the group in a one-to-one or a one-to-many type. The users included in the group may select a counterpart to which the voice signal is transmitted through a screen of the electronic device and transmit the voice signal to the selected counterpart by pressing the button.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

When transmitting a voice signal to a counterpart by using push-to-talk (PTT) group communication, the user should select the counterpart on a screen of an electronic device and make a touch input on a button while watching the screen, which causes cumbersomeness. Further, since the user should transmit a voice signal by controlling the screen, the transmission is dangerous during an action requiring physical activity.

Aspects of the present disclosure are to address the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a communication operation method and an electronic device for supporting the same according to an embodiment of the present disclosure may detect a motion of the electronic device, select an external electronic device based on the motion, and communicate with the selected external electronic device.

Another aspect of the present disclosure is to provide a communication operation method and an electronic device for supporting the same. When the electronic device receives a voice signal including a direction indication language, the electronic device may select an external electronic device based on the direction indication language and communicate with the selected external electronic device.

In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a first communication unit configured to communicate with at least one external electronic device, a sensor unit configured to detect a motion of the electronic device, and a controller configured to form a group for communication with the at least one external electronic device, receive location information from the at least one external electronic device, select at least one of the at least one external electronic device to communicate with, based on the motion of the electronic device detected through the sensor unit, and control the first communication unit to communicate with at least one selected external electronic device.

In accordance with another aspect of the present disclosure, an electronic device is provided.

FIG. 3 is a flowchart illustrating a communication operation method of a transmission electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3, the controller 280 forms a group for communication in operation 301. According to an embodiment of the present disclosure, the controller 280 may form a group with at least one external electronic device by using an ad hoc network based on short-range communication, for example, Wi-Fi.

The controller 280 receives location information from the external electronic device in operation 303. The controller 280 may acquire current location information on the electronic device 200 and transmit the acquired location information to the external electronic device. The electronic devices within the group may transmit/receive (e.g., share) the acquired location information through the location collector 240. The electronic devices within the group may periodically acquire and share location information. This may correspond to an operation for identifying movements of the external electronic devices. According to an embodiment of the present disclosure, the location information may be acquired using a neighboring AP. The controller 280 may transmit a broadcasting message in a particular direction through antenna beamforming of the electronic device 200 and acquire the location information through a response message of the broadcasting message.

According to an embodiment of the present disclosure, when sharing the location information, the electronic devices within the group may also share information on the electronic devices. The information on the electronic device may include device identification information and image information. When the information on the electronic device includes the image information, the controller 280 may display, on the display unit 231, an icon of the external electronic device by using the image information based on the location information in operation 305 described below. When the information on the electronic device includes no image information, the controller 280 may determine whether there is information matching the external electronic device in contacts of the electronic device 200. When the contacts include information matching the external electronic device, the controller 280 may display an icon by using an image of the external electronic device stored in the contacts. When the information on the electronic device includes no image information, the controller 280 may display an icon by using a default image. Alternatively, when the information on the electronic device includes no image information, the controller 280 may display an icon by using an image acquired through analysis of the voice signal received in FIG. 8 described below.

The controller 280 compares the received location information on the external electronic device and current location information on the electronic device 200, and determines and displays relative direction information and distance information on the external electronic device in operation 305. The controller 280 may calculate the relative direction information and distance information on the external electronic devices within the group based on the received location information. According to an embodiment of the present disclosure, the relative direction information and distance information may be information for determining locations of the icons of the external electronic devices based on the icon of the electronic device 200. As described above, the electronic devices within the group may periodically share the location information. The controller 280 may update and display the relative direction information and distance information on each electronic device within the group which is moving based on the periodically shared location information. The controller 280 may reflect the relative direction information and distance information calculated based on the received location information to display the icons of the external electronic devices on the display unit 231.

According to an embodiment of the present disclosure, a method of displaying the icons of the external electronic devices may include a method of displaying the icons of the external electronic devices according to the relative direction information and distance information on the external electronic devices based on the icon of the electronic device and a method of controlling and displaying the icons of the external electronic devices in proportion to the distance information based on the relative direction information on the external electronic devices from the icon of the electronic device (e.g., increase or decrease the size of the icons). A detailed description of the method of displaying the icons of the external electronic devices is described below with reference to FIGS. 4A and 4B.

The controller 280 detects a motion of the electronic device 200 in operation 306. As described above, the controller 280 may detect the motion of the electronic device 200 by using the acceleration sensor and the gyro sensor.

The controller 280 selects the external electronic device based on the motion of the electronic device in operation 307. An operation for selecting the external electronic device is an operation for communicating with the external electronic device. The operation for selecting the external electronic device may be an operation for indicating, by a head of the electronic device, a particular direction in which the external electronic device to communicate with exists. The communication may include transmission of a text message, a voice message, or data (for example, pictures or dynamic images).

According to another embodiment of the present disclosure, the controller 280 may receive motion information on a wearable device connected through the second communication unit 212 from the wearable device. The controller 280 may select the external electronic device to communicate with, based on the motion information. When the external electronic device to communicate with is selected using the wearable device, the controller 280 may indirectly input a gesture without a direct gesture input into the electronic device (e.g., a touch input on the icon of the external electronic device displayed on the display unit 231). When the wearable device is used, the wearable device may include a motion sensor (e.g., including the acceleration sensor and the gyro sensor) capable of recognizing the gesture. The wearable device may communicate with the electronic device 200 through the second communication unit 212. The wearable device may select the external electronic device through the gesture input in a direction of the head of the electronic device 200 and the motion of the wearable device worn on the user's wrist. For example, the controller 280 may select the external electronic device located in the particular direction through an action of the finger or arm indicating the particular direction (for example, a motion in at least one of upward, downward, leftward, and rightward directions) in a state where the wearable device is worn. The wearable device may transmit direction information to the electronic device 200.

The controller 280 may compare the direction information received from the wearable device with the calculated relative direction information on the external electronic device. When an external electronic device having matching direction information, based on a result of the comparison, the controller 280 may determine the matching external electronic device as the external electronic device to communicate with. The controller 280 may display the icons of the electronic device and the external electronic device to communicate with such that the icons are connected to each other through a connection line. The controller 280 may activate and display the icon of the external electronic device to communicate with.

According to an embodiment of the present disclosure, the controller 280 may accurately select the external electronic device in an indication direction according to the action of the finger or arm through Microsoft Kinect™ and/or an electromyography (EMG) sensor. The controller 280 may recognize an arm action and a finger motion through the Kinect™. The EMG sensor may be worn on the arm, and the controller 280 may measure a motion of the arm muscle through the EMG sensor and accurately recognize an indication direction according to the arm action.

The controller 280 may measure the motion of the electronic device through the acceleration sensor and the gyro sensor and may measure a motion angle in a direction of the head of the electronic device through the earth magnetic field sensor to select the external electronic device. The direction of the head of the electronic device may refer to an upper portion of the electronic device 200. For example, the controller 280 may store an initial azimuth of the electronic device 200 and a maximum azimuth of the motion of the electronic device 200. The controller 280 may select the external electronic device included in a range of the initial azimuth and the maximum azimuth as the external electronic device to communicate with. The controller 280 may detect a motion of the electronic device 200 in at least one of upward, downward, leftward, and rightward directions and select at least one external electronic device to communicate with. The controller 280 may select at least one external electronic device to communicate with according to the motion of the electronic device 200 in various patterns, such as a circular pattern.

The controller 280 may compare direction information according to a motion angle indicated by the head based on the motion of the electronic device with the calculated relative direction information on the external electronic device. When an external electronic device has matching direction information, based on a result of the comparison, the controller 280 may determine the external electronic device having the matching direction information as the external electronic device to communicate with. When the external electronic device is selected, the controller 280 may control the display unit 231 to display the icons of the electronic device and the selected external electronic device such that the icons are connected to each other through a connection line. The controller 280 may activate and display the icon of the selected external electronic device (for example, display the icon with a solid line). The controller 280 may display the icons such that the selected external electronic device is distinguished from the external electronic device, which has not been selected, by using different character colors or background colors of the icons.

The controller 280 may control the display unit 231 to display information on the selected external electronic device through a notification. The display unit 231 may display only the icon of the selected external electronic device or only information on the external electronic device (for example, image information or contact information) without displaying all the icons of the external electronic devices within the group.

According to an embodiment of the present disclosure, after selecting the external electronic device to communicate with, the controller 280 may perform an operation for inputting a message to be transmitted to the external electronic device. The type of the message may include a voice message such as push-to-talk (PTT), an instant message through a text input device, and a multimedia message service (MMS) message having a file attached thereto. After inputting the message, the controller 280 may detect an input for transmitting the message. According to an embodiment of the present disclosure, the input for transmitting the message may be a general request signal in a half duplex communication and may be, for example, an operation for pressing a hardware key or a send key implemented in the display unit 231 in software. The controller 280 may recognize the input for transmitting the message as an input for acquiring a right to control or a right to speak in voice communication between electronic devices within the group. For example, the user may input a voice message by pressing a microphone button displayed on the display unit 231, and then transmit the voice message to the selected external electronic device.

According to an embodiment of the present disclosure, when the controller 280 photographs and shares, for example, a dynamic image, the controller 280 may extract only a voice of the user who uses the selected external electronic device and encode the extracted voice together with the dynamic image. Since a method of extracting only the voice from the selected external electronic device is an already known technology and thus is apparent to those skilled in the art, a detailed description thereof will be omitted.

In operation 309, the controller 280 communicates with the external electronic device selected in operation 307. The communication may include an operation for transmitting a text message, a voice message, or data (for example, pictures or dynamic images). When the electronic device 200 communicates with the selected external electronic device, the controller 280 may also transmit direction information on the electronic device 200.

A method of selecting and communicating with the external electronic device based on the motion of the electronic device is described below with reference to FIGS. 5A to 5D.

FIGS. 4A and 4B illustrate a method of displaying icons of external electronic devices based on relative direction information and distance information on the external electronic devices according to an embodiment of the present disclosure.

Referring to FIGS. 4A and 4B, it is assumed that users having electronic devices form a riding group to communicate during the riding according to an embodiment of the present disclosure.

Referring to FIG. 4A, the electronic device 103 of the user within the formed riding group, an electronic device of “David”, an electronic device of “Gaspard”, and an electronic device of “Grag” may share current location information. The electronic device 103 of the user may receive the location information from the electronic device of “David”, the electronic device of “Gaspard”, and the electronic device of “Grag” and calculate relative direction information and distance information on each of the electronic devices. The electronic device 103 may display icons of the external electronic devices according to the calculated relative direction information and distance information based on the icon 103a of the electronic device 103. When it is assumed that the icon of the electronic device 103 of the user is located in a direction of 0 degrees, the controller 280 may determine that the icon 105a of the electronic device of “David” is located in a direction of 300 degrees, determine that the icon 107a of the electronic device of “Gaspard” is located in a direction of 340 degrees, and determine that the icon 109a of the electronic device of “Grag” is located in a direction of 5 degrees according to the relative direction information and distance information based on the icon 103a of the electronic device 103 of the user.

As described above, the icons of the external electronic devices (e.g., 105a, 107a, and 109a) may be configured by image information included in the shared information on the electronic devices. When the information on the electronic device includes no image information, the controller 280 may determine whether there is information, which matches the external electronic device, in contacts of the electronic device 103. When the information includes information matching the external electronic device, the controller 280 may display an icon by using an image of the external electronic device stored in the contacts. Alternatively, the controller 280 may display the icon by using a default image.

The controller 280 may receive location information from the external electronic devices, calculate relative direction information and distance information on the external electronic devices based on the location information, and display the icons of the external electronic devices on corresponding locations. The user may intuitively identify the locations of the external electronic devices within the group by displaying the icons of the external electronic devices according to the relative direction information and distance information.

FIG. 4B illustrates another embodiment for displaying the icons of the external electronic devices based on the relative direction information and distance information on the external electronic devices. The controller 280 may display the icons according to the relative direction information on the external electronic devices based on the icon 103a of the electronic device 103 of the user, and control and display sizes of the icons of the external electronic devices in proportion to the distance information. For example, the controller 280 may display the icon of the external electronic device, which is located closer to the icon 103a of the electronic device 103 of the user, with the larger size. Alternatively, the controller 280 may display the icon of the external electronic device, which is located farther from the icon 103a of the electronic device 103 of the user, with the smaller size. Accordingly, the user may intuitively identify whether the external electronic device is located far from or close to his/her own electronic device. For example, as illustrated in FIG. 4B, the controller 280 may display the icons according to the relative direction information based on the icon 103a of the electronic device 103 of the user, and place the icon 105a of the electronic device of “David”, which is located behind and close to the electronic device 103, in a direction of 200 degrees and display the icon 105a with the large size in proportion to the distance information. The controller 280 may place the icon 107a of the electronic device of “Gaspard”, which is located ahead of and close to the electronic device 103 of the user, in a direction of 340 degrees and display the icon 107a with the large size. The controller 280 may place the icon 109a of the electronic device of “Grag”, which is located ahead of and far from the electronic device 103 of the user, in a direction of 45 degrees and display the icon 109a with the small size.

FIGS. 5A to 5D illustrate a method of selecting and communicating with the external electronic device based on a motion of an electronic device according to an embodiment of the present disclosure.

Referring to FIGS. 5A to 5D, when it is assumed that the electronic device 103 is located in a direction of 0 degrees as indicated reference numeral 501 of FIG. 5A, the electronic device 103 may acquire relative direction information containing the electronic device 105 of “David” located in a direction of 300 degrees, the electronic device 107 of “Gaspard” located in a direction of 340 degrees, and the electronic device of “Grag” located in a direction of 5 degrees based on the electronic device 109.

When the motion of the electronic device 103 is detected through the sensor unit 270, the controller 280 may select the external electronic device located in a direction indicated by a head of the electronic device 103 according to the motion. The controller 280 may compare the direction indicated by the head of the electronic device 103 with the relative direction information on the external electronic devices. Based on a result of the comparison, the controller 280 may determine that the direction indicated by the head of the electronic device 103 matches the relative direction information on the electronic device 109 of “Grag” in reference numeral 501 of FIG. 5A. Accordingly, the controller 280 may select the electronic device 109 of “Grag” as the external electronic device to communicate with.

According to an embodiment of the present disclosure, as illustrated in reference numeral503 of FIG. 5A, the controller 280 may display the icons of the external electronic devices based on the calculated relative direction information and distance information on the external electronic devices.

Accordingly, the user may intuitively identify the communication connection between the electronic device 103 and the electronic device 109 of “Grag”. Further, when the controller 280 receives a voice signal of “Hey! Grag”505, the controller 280 may transmit the voice signal to the electronic device 109 of “Grag”.

The method of selecting the external electronic device based on the motion of the electronic device according to another embodiment of the present disclosure is described with reference to FIG. 5B. As indicated by reference numeral 511 of FIG. 5B, the electronic device 103 may acquire relative direction information containing the electronic device 105 of “David” located in a direction of 300 degrees, the electronic device 107 of “Gaspard” located in a direction of 340 degrees, and the electronic device 109 of “Grag” located in a direction of 5 degrees based on the electronic device 103 located in a direction of 0 degrees.

The controller 280 may detect the motion of the electronic device 103 moving in a left direction through the sensor unit 270 as indicated by reference numeral 515. The controller 280 may store an angle of the electronic device 109 of “Grag” as an initial azimuth, detect the motion of the electronic device 103 in a left direction 515 from the initial azimuth, and store an angle of the electronic device 105 of “David” as a maximum azimuth. The maximum azimuth may be an angle in a range including the electronic device 109 of “Grag”, the electronic device 107 of “Gaspard”, and the electronic device 105 of “David”. The controller 208 may select the electronic device 105 of “David”, the electronic device 107 of “Gaspard”, and the electronic device 109 of “Grag” as the external electronic devices to communicate with, based on the initial azimuth and the maximum azimuth. When the controller receives a voice signal of “Hurry up! !”517 after selecting the external electronic device to communicate with based on the initial azimuth and the maximum azimuth, the controller 280 may transmit the received voice signal to the selected external electronic devices (for example, the electronic device 105 of “David”, the electronic device 107 of “Gaspard”, and the electronic device 109 of “Grag”).

According to an embodiment of the present disclosure, as illustrated in reference numeral 513 of FIG. 5B, the controller 280 may display the icons of the external electronic devices based on the calculated relative direction information and distance information on the external electronic devices. As described above, the electronic device 103 may display the icons such that the icon 105a of the electronic device of “David” is located in a direction of 300 degrees, the icon 107a of the electronic device of “Gaspard” is located in a direction of 340 degrees, and the icon 109a of the electronic device of “Grag” is located in a direction of 5 degrees according to the relative direction information and distance information based on the icon 103a of the electronic device 103 located in a direction of 0 degrees. The controller 280 may display the icons such that the icons (e.g., icons 105a, 107a, and 109a) of the selected external electronic devices are connected through connection lines based on the icon 103a of the electronic device and the aforementioned initial azimuth and maximum azimuth. Accordingly, the user may intuitively identify the communication connection between the electronic device 103, and the electronic device 105 of “David”, the electronic device 107 of “Gaspard”, and the electronic device 109 of “Grag”.

The method of selecting the external electronic device based on the motion of the electronic device according to another embodiment of the present disclosure is described with reference to FIG. 5C. As indicated by reference numeral 521 of FIG. 5C, the electronic device 103 may acquire relative direction information containing the icon 105a of the electronic device of “David” located in a direction of 200 degrees, the icon 107a of the electronic device of “Gaspard” located in a direction of 340 degrees, and the icon 109a of the electronic device of “Grag” located in a direction of 45 degrees based on the icon 103a of the electronic device of the user located in a direction of 0 degrees. As described above, the controller 280 may display the icon of the external electronic device located close to the electronic device 103 with the large size and the icon of the electronic device located far from the electronic device 103 with the small size in proportion to the distance information on the external electronic devices.

The controller 280 may detect the motion of the electronic device 103 moving in a direction of upward and downward directions 525 in reference numeral 523 of FIG. 5C. When the controller 280 detects the motion of the electronic device 103 in the upward and downward directions 525, the controller 280 may select the external electronic devices located ahead the electronic device 103 (e.g., the electronic device 107 of “Gaspard” and the electronic device 109 of “Grag”) and/or the external electronic device located behind the electronic device 103 (e.g., the electronic device 105 of “David”) as the external electronic devices to communicate with. The controller 280 may select the external electronic device as the external electronic device to communicate with, according to a motion angle in the upward and downward directions 525.

According to an embodiment of the present disclosure, the controller 280 may control to activate and display the icons of the selected external electronic devices based on the motion of the electronic device. For example, the controller 280 may automatically activate and display the icon 105a of the electronic device of “David” (e.g., display the icon 105a with the solid line) as indicated by reference numeral 521 of FIG. 5C. Accordingly, the user may identify that the electronic device of “David” is selected as the external electronic device to communicate with. In contrast, the controller 280 may deactivate and display the icons of the external electronic devices which have not been selected, for example, the icon 107a of the electronic device of “Gaspard” and the icon 109a of the electronic device of “Grag” (e.g., display the icons 107a and 109a with the dotted line) in reference numeral 521 of FIG. 5C. By activating or deactivating and displaying the icons, the user may distinguish the external electronic device to communicate with and the external electronic device to not communicate with. Subsequently, the controller 280 may communicate with the external electronic device corresponding to the activated icon.

The method of selecting the external electronic device to communicate with is not limited to a method of selecting the external electronic device based on the motion of the electronic device.

Accordingly, the user may intuitively identify the communication connection between the electronic device 103 and the electronic device 107 of “Gaspard”.

FIG. 8 is a flowchart illustrating a communication operation method of a reception electronic device according to an embodiment of the present disclosure.

Referring to FIG. 8, the controller 280 activates group communication in operation 801. According to an embodiment of the present disclosure, an operation for activating the group communication may refer to forming a group with at least one external electronic device. The controller 280 may form a group with at least one external electronic device by using an ad hoc network based on short-range communication, for example, Wi-Fi.

The controller 280 receives location information from the external electronic device in operation 803. The controller 280 acquires current location information on the electronic device 200 and transmit the acquired location information to the external electronic device within the group. The electronic devices within the group may transmit/receive the location information acquired through the location collector 240 to share the location information. The electronic devices within the group may periodically acquire and share location information.

The electronic devices within the group may share information on the electronic devices when sharing the location information. The information on the electronic device may include device identification information and image information. When the information on the electronic device includes the image information, the controller 280 may display, on the display unit 231, an icon of the external electronic device by using the image information based on the location information in operation 805 described below. When the information on the electronic device includes no image information, the controller 280 may display an icon by using an image acquired through analysis of the received voice signal.

The controller 280 compares the received location information and the acquired location information on the electronic device 200, and determines and displays relative direction information and distance information on the external electronic devices in operation 805. The controller 280 may calculate the relative direction information and the distance information on the external electronic devices within the group based on the received location information. According to an embodiment of the present disclosure, the relative direction information and the distance information may be information for determining locations of the icons of the external electronic devices based on the icon of the electronic device 200. The controller 280 may reflect the relative direction information and the distance information calculated based on the received location information to display the icons of the external electronic devices.

Since operations 801 to 805 of FIG. 8 are identical to operations 301 to 305 of FIG. 3, a detailed description thereof will be omitted.

The controller 280 determines whether a communication request is received from one of the external electronic devices within the group in operation 807. For example, the communication request may be an operation for receiving a text message, a voice message, or data (e.g., pictures or dynamic images) from one of the external electronic devices within the group.

When the communication request is not received from the one of the external electronic devices, the controller 280 receives the location information from the external electronic devices within the group in operation 803.

When the communication request is received from one of the external electronic devices, the controller 280 notifies of direction information on the external electronic device in operation 809 and communicates with the external electronic device in operation 811. According to an embodiment of the present disclosure, a method of notifying of the direction information on the external electronic device may include a method of controlling localization according to the relative direction information on the external electronic device and a method of displaying a text message in accordance with the relative direction information on the external electronic device.

According to an embodiment of the present disclosure, when the controller 280 receives a voice message from the external electronic device, the controller 280 may control localization based on relative direction information on the received voice message. The method of controlling the localization may be performed when there are two or more audio output devices (e.g., earphones). The controller 280 may control the localization to output a voice message to the corresponding audio output device (e.g., in a case of the earphones, a left earphone and a right earphone). When the voice message is received, direction information on the external electronic device may be also received. The controller 280 may reversely calculate the relative direction information on the external electronic device by using the received direction information on the external electronic device.

For example, when the user wears the earphones, the controller 280 may output an audio signal to an earphone (e.g., the left earphone or the right earphone) corresponding to the direction, in which the localization is controlled, based on the relative direction information. The user may predict the direction of the external electronic device, from which the voice message is transmitted, through the output audio signal.

According to an embodiment of the present disclosure, when the voice message is received, the controller 280 may output a text message based on the relative direction information on the transmitted voice message. For example, when the message transmitted by the external electronic device located in the right side is received, the controller 280 may display the message by applying a visual effect for gradually moving the message in a left direction from a right boundary of the display unit 231.

The method of notifying of the relative direction information on the external electronic device by the reception electronic device is described below with reference to FIGS. 9A and 9B.

According to an embodiment of the present disclosure, when the icons of the external electronic devices are displayed in operation 805, if the icon is set as a default image or is displayed as null (i.e., when the information on the electronic device includes no image information) the controller 280 may analyze the received voice message and display the icon by using an image according to the analysis. When the voice message is received from the external electronic device, the controller 280 may compare a voice included in the voice message with speaker voice information stored in the storage unit 220. Through the comparison operation, the controller 280 may distinguish a gender or age (adult/child) which matches the voice, and display the determined image information as the icon of the external electronic device. The controller 280 may replace the basic image set by default with the image according to the voice analysis result. For example, when a female voice is determined based on the voice comparison result, the controller 280 may display a female image as the icon of the corresponding external electronic device. Alternatively, when a male voice is determined based on the voice comparison result, the controller 280 may display a male image as the icon of the corresponding external electronic device.

According to an embodiment of the present disclosure, the controller 280 may change a background image of a message chatting window displayed on the wearable device connected through the second communication unit 212 as well as the icons of the external electronic devices. For example, the controller 280 may transmit information corresponding to the analyzed voice to the wearable device. The wearable device having received the information may change a color or an image of the message chatting window based on the information. Alternatively, the wearable device may allow an external notification light (LED) to have a color based on the information. For example, in a case of the female based on the voice comparison result, the controller 280 may display a pink color. In a case of the child, the controller 280 may display a yellow color. A detailed description thereof will be made below with reference to FIG. 9C.

FIGS. 9A to 9C illustrate a method of notifying of relative direction information on the external electronic devices by the reception electronic device according to an embodiment of the present disclosure.

Referring to FIGS. 9A to 9C, as illustrated in reference numeral 901 of FIG. 9A, the electronic device 105 of “David” may receive a voice message from the external electronic device 103 located at the lower right side. The electronic device 105 of “David” may control to output the message only from a right audio device by controlling localization corresponding to the lower right direction. By controlling to output the message only from the right audio device, the user may receive an effect as if the sound comes from the lower right direction. As illustrated in reference numeral 903 of FIG. 9A, when the external electronic device 103 transmits a message to the electronic device 105, the electronic device 105 may control a range 909d among localization control ranges 909a, 909b, 909c, and 909d based on relative direction information on the external electronic device 103 by controlling the localization, thereby significantly adjusting an audio output range as indicated by reference numeral 911. An audio output device 907 may have a left audio output device 907a and a right audio output device 907b, and the controller 280 may make a control to output an audio signal only from the right audio output device 907b corresponding to the relative direction information on the external electronic device having transmitted the message. The electronic device according to an embodiment of the present disclosure may provide the user with an effect as if a sound comes from the diagonal back side. The user may know a message transmission direction through the direction in which the audio signal is output (for example, the right output device).

Referring to FIG. 9B, the electronic device 105 receives a message “Hey, David” from the electronic device of “Peter”. As illustrated in FIG. 9B, the electronic device 105 and the electronic device of “Peter” are communicating with each other while the icon 105a of the electronic device 105 and the icon 103a of the electronic device of “Peter” are connected through a connection line. When the electronic device 105 receives a message from the electronic device of “Peter” located at the lower right side, the electronic device 105 may apply a visual effect as if the message “Hey, David” moves from the right side to the left side sequentially as indicated by reference numerals 921, 923, and 925 of FIG. 9B to display the message. Alternatively, the controller 280 may apply a visual effect as if the message moves from the lower right diagonal side to the upper left diagonal side to display the message. The controller 280 may control the display unit 231 to display the message while the message moves from the right side to the left side sequentially like “Hey”926 as indicated by reference numeral 921 of FIG. 9B, “Hey, Day”927 as indicated by reference numeral 923 of FIG. 9B, and “Hey, David”928 as indicated by reference numeral 925 of FIG. 9B.

When the voice message is received from the external electronic device, the controller 280 may compare a voice included in the voice message with speaker voice information stored in the storage unit 220 as illustrated reference numeral 931 of FIG. 9C. Through the comparison operation, the controller 280 may determine speaker information (e.g., gender or age e.g. adult/child) corresponding to the voice and display an image 937 according to the determination. Image information corresponding to the speaker information may be also stored in the storage unit 220.

According to an embodiment of the present disclosure, when the controller 280 is connected to a wearable device 933 for communication, the controller 280 may transmit the speaker information to the wearable device 933. The wearable device 933 may display a color or an image corresponding to the received speaker information on the screen of the wearable device 933 as indicated by reference numeral 935 of FIG. 9C.

While the present has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes to form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
