Further, the first mobile terminal is assigned a reference numeral '200', and the second mobile terminal is assigned a reference numeral '300'.

The first mobile terminal 200 and the second mobile terminal 300 may include the wireless communication unit 110, the memory 160, the display unit 151, and the controller 180 in common in the configuration illustrated in FIG. 1. Can be. In some cases, at least one of the first mobile terminal 200 and the second mobile terminal 300 may further include at least one of the microphone 122, the sensing unit 140, and the sound output unit 152. In the following embodiment, for convenience of description, the first element is prefixed with a 'first' and the second element is prefixed with a 'second'. Let's add.

Furthermore, when the display unit of the first mobile terminal 200 and the second mobile terminal 300 is a touch screen, the present invention can be more easily implemented, the first mobile terminal 200 and the second mobile terminal 300 It is assumed that the display unit in FIG. 9 is a touch screen.

For convenience of description, a person who wants to use the first and second mobile terminals 200 and 300 according to the present invention will be referred to as a 'user', and a counterpart terminal performing a phone call with the first mobile terminal 200. Or its user will be referred to as 'call party'.

Referring to the drawings, the operation of the first and second mobile terminals 200 and 300 according to the present invention will be described in detail.

4 is an operation flowchart of a first mobile terminal according to an embodiment of the present invention. First, a communication channel may be established between the first mobile terminal 200 and the second mobile terminal 300 (S401). Short-range communication technology may be used to establish a communication channel between the first mobile terminal 200 and the second mobile terminal 300. Specifically, short-range communication technology such as Bluetooth, Zigbee, IEEE 802.11x, Wi-Fi Direct may be used.

For example, FIG. 5 is an exemplary diagram for explaining that a first mobile terminal and a second mobile terminal are paired with each other via Bluetooth. As in the example illustrated in FIG. 5, when the first mobile terminal 200 requests pairing to the second mobile terminal 300 based on a user input, the second control unit of the second mobile terminal 300 is provided. May control to display a pop-up window 510 for determining whether to accept the pairing request of the first mobile terminal 200. According to a user input for the pop-up window 510, a communication channel between the first mobile terminal 200 and the second mobile terminal 300 may be established.

In a state in which a communication channel between the first mobile terminal 200 and the second mobile terminal 300 is formed, the first mobile terminal 200 may initiate a telephone call with an arbitrary counterpart (S402). Here, the phone call between the first mobile terminal 200 and any counterpart may include various types of call methods such as voice call, video call and VoIP call.

If the separation distance between the first mobile terminal 200 and the second mobile terminal 300 is narrowed to less than or equal to a predetermined distance in a state of a phone call with an arbitrary counterpart (S403), the first controller automatically or secondly moves. In response to the request of the terminal 300, the second mobile terminal 300 may provide a content list to be shared with the call counterpart (S404). Here, the preset distance may be fixed to a specific value (for example, 2m) but may be set to be changed by the user (for example, 2m to 3m). The first control unit may measure a distance from the second mobile terminal 300 using a sensor device such as a proximity sensor or a distance sensor, but based on the strength of the signal received from the second mobile terminal 300. The distance from the mobile terminal 300 may be measured.

The content to be shared with the other party is not the content stored in the first memory, but the content stored in the second mobile terminal 300 or the cloud server commonly used by the first mobile terminal 200 or the second mobile terminal 300. In the case of uploaded content, the providing of the content list to the second mobile terminal 300 may be omitted. Otherwise, when at least some of the content stored in the first memory is included in the category of the content to be shared with the counterpart, the first controller can provide the content list to the second mobile terminal 300.

In order to reduce the communication overhead between the first mobile terminal 200 and the second mobile terminal 300, the first controller instead of transmitting the content itself to be shared with the other party, a thumbnail of content to be shared with the other party ( Alternatively, the content list including the preview image may be transmitted. If the second mobile terminal 300 receives the request for transmission of at least one of the content list, the first controller can provide the content requested by the second mobile terminal 300 to the second mobile terminal 300. will be.

In providing the content list to the second mobile terminal 300, the first controller selects the content related to the call counterpart from among the contents stored in the first memory, and then selects a thumbnail (or preview image) of the selected content. The controlled content list may be controlled to be provided to the second mobile terminal 300. For example, an image or video photographed by a call partner, a memo recorded with a schedule with a call counterpart, and a name identifying the call counterpart may be included in a category of content associated with the call counterpart.

The first controller may further provide the converted text data obtained by converting a voice signal generated during a phone call to text (STT) to the second mobile terminal 300 (S405). In this case, the first controller may transmit both the converted text based on the voice uttered by the call counterpart and the converted text based on the voice spoken by the user, to the second mobile terminal 300, The second mobile terminal 300 may provide only one of the converted text based on the spoken voice and the converted text based on the voice spoken by the user. Whether to provide both texts to the second mobile terminal 300 or only one of the two texts may be adjusted based on a setting stored in the first memory, and the setting may be manually adjusted by the user. It may be.

However, the step of transmitting text data to the second mobile terminal 300 will not necessarily be an essential step to be performed. In some cases, the step of transmitting text data to the second mobile terminal 300 may be omitted. Furthermore, providing the text data to the second mobile terminal 300 need not necessarily be performed after providing the content list. Providing the text data to the second mobile terminal 300 may be performed prior to or simultaneously with providing the content list.

When the second mobile terminal 300 is requested to share predetermined content with the call counterpart during a phone call (S406), the first controller transmits the content requested by the second mobile terminal 300 to the call counterpart, and then the call counterpart. And control to share the content (S407).

In case of transmitting content to be shared with the called party by the request of the second mobile terminal 300, in order to allow the calling party and the user to acquire the same user experience (that is, to enjoy the same content). In the second mobile terminal 300, content transmitted to a call counterpart may be output. Since the content transmitted to the call counterpart is output through the second mobile terminal 300 instead of the first mobile terminal 200, the user continues the phone call to the first mobile terminal 200 and the second mobile terminal 300. ) Will be able to enjoy shared content with the other party.

If the content shared with the call counterpart is accompanied by the output of an audio signal such as music or video, the first controller can adjust the volume of the content so as not to disturb the telephone call. For example, when the size of the sound signal input to the first microphone exceeds a preset allowable value or is greater than or equal to a predetermined level relative to the size of the voice during a phone call, the first control unit controls the output volume of the content to the second mobile terminal 300. By sending a control command to adjust, the output volume of the content can be controlled to be automatically reduced.

Although the first mobile terminal 200 receives a request of the second mobile terminal 300 to request the content sharing from the call counterpart, on the contrary, it may be requested to share the content from the call counterpart. When the distance to the second mobile terminal 300 is set to be equal to or less than the predetermined distance, when receiving the content for sharing from the call counterpart (S408), the first control unit receives the content received from the call counterpart the second mobile terminal. In operation S409, it may transmit to the 300. By controlling the received content to be output through the second mobile terminal 300, the user can check the received content without removing the first mobile terminal 200 in the ear to confirm the first touch screen. Can be.

If the content for sharing is received from the second mobile terminal 300 while the separation distance from the second mobile terminal 300 is greater than the preset distance, the first controller outputs the content shared on the first touch screen. You can do it. However, even after receiving the content for sharing from the second mobile terminal 300, if the separation distance with the second mobile terminal 300 is less than or equal to the predetermined distance, the first control unit is the content received from the call counterpart 2 may be controlled to be transmitted to the mobile terminal (300).

Next, the operation of the second mobile terminal 300 will be described in detail.

6 is a flowchart illustrating operations of a second mobile terminal according to an embodiment of the present invention. As described with reference to FIG. 4, a communication channel may be established between the first mobile terminal 200 and the second mobile terminal 300 (S601). When the communication distance with the first mobile terminal 200 is established, when it is determined that the separation distance with the first mobile terminal 200 during a phone call is less than or equal to a predetermined distance (S602), the second controller may control the first mobile terminal ( The call counterpart on the call with 200 may be identified as the content sharing target, and a content list to be shared with the call counterpart may be displayed (S603).

FIG. 7 illustrates a change in screen output of a second mobile terminal when it is determined that a distance from the first mobile terminal in a telephone call is less than or equal to a preset distance. FIG. 7A illustrates an output of the second mobile terminal 300 before the separation distance from the first mobile terminal 200 is narrowed to a predetermined distance or less, and FIG. 7B illustrates the first movement. An example of an output of the second mobile terminal 300 after the separation distance from the terminal 200 is narrowed to a predetermined distance or less.

As shown in FIGS. 7A and 7B, when the separation distance from the first mobile terminal 200 is smaller than or equal to a preset distance, the second control unit may control the second touch screen. The content list to be shared with the call counterpart may be controlled. In FIG. 7B, an image, a schedule, and a memo item are illustrated as types of content to be shared with a call counterpart. As shown in the example of FIG. 7B, the second controller may output various types of content lists at the same time, but may also output only one type of content list. For convenience of drawing creation, in the following drawings, it is assumed that any one type of content list is displayed on the second touch screen.

As in the example shown in Figs. 7A and 7B, prior to switching the output of the second mobile terminal 300, the second control unit is as in the example shown in Fig. 7C. The control unit may control to output a pop-up window for inquiring whether to switch the output of the second mobile terminal 300. The second controller may determine whether to display a content list to be shared with the call counterpart based on the user input for the pop-up window illustrated in FIG. 7C.

The content list displayed on the second touch screen includes content stored in the first mobile terminal 200, content stored in the second mobile terminal 300, and content stored in a cloud server shared by the first and second mobile terminals 200 and 300. It may point to at least one of. In order to display the content list stored in the first mobile terminal 200 or the content list stored in the cloud server, the second mobile terminal 300 may receive the content list from the first mobile terminal 200 or the cloud server. .

In displaying the content list, the second controller may control only the content associated with the call counterpart to be exposed in the content list. Here, the content related to the call partner may include an image or video photographed by the call partner, a schedule associated with the called party (eg, schedule data recording an appointment with the called party), and a memo associated with the called party (eg, a call). Name data of the other party or memo data including the phone number of the other party). In order to extract content related to the call counterpart and to display only the content in order to display the extracted content list, the second controller can receive information of the call counterpart from the first mobile terminal 200. Here, the information of the call counterpart may include an image photographing the call counterpart, a name (for example, a name, a social network service (SNS) account, etc.) for identifying the call counterpart, a phone number of the call counterpart, and the like. As another example, when displaying a list of content, the second controller may extract content associated with a call counterpart and display the extracted content in a separate group. Referring to FIG. 8, a method of displaying a content list associated with a call counterpart will be described in more detail.

8 is an exemplary diagram for describing a method of displaying content associated with a call counterpart. For convenience of explanation, it is assumed that the content to be shared with the call counterpart is an image.

8 (a) shows a virtual view of the call counterpart. The second controller extracts an image of the same person as the call counterpart shown in FIG. 8A, and displays a list of images of the call counterpart taken as shown in the example of FIG. 8B. Can be controlled.

As another example, as shown in the example of FIG. 8C, the second controller can display a list of content while displaying the captured image of the call counterpart as a separate group 810. In either case, the user can easily recognize the content associated with the call counterpart.

Referring back to FIG. 6, the second mobile terminal 300 may receive text data from the first mobile terminal 200 in a phone call (S604). Here, the text data may be data obtained by converting a voice signal generated during a phone call into text and converting at least one of a voice spoken by the call counterpart and a voice spoken by the user into text. The text data may be transmitted to the second mobile terminal 300 by the transmission request of the second mobile terminal 300, but may be automatically transmitted to the second mobile terminal 300.

When the text data is transmitted by the transmission request of the second mobile terminal 300, the second controller may include text data generated based on the voice spoken by the user and text data generated based on the voice spoken by the call counterpart. The first mobile terminal 200 may be requested to transmit at least one. Whether to request either may be adjusted according to a setting stored in the second memory, and the setting may be manually adjusted by the user.

The second controller may display the text data received from the first mobile terminal 200 in real time, but does not necessarily display it. If the text data received from the first mobile terminal 200 is displayed, even if the voice of the call counterpart is not properly recognized, the message to be communicated by the call counterpart can be recognized through the output of the second touch screen.

9 is a diagram illustrating that text data is output to a second mobile terminal. As shown in the example of FIG. 9A, the second controller can control the text data received from the first mobile terminal 200 to be displayed. In this case, when a specific word is repeated a predetermined number of times in the conversation content, the second controller may control the specific word repeated a predetermined number of times or more to be highlighted as shown in the example of FIG. 9B.

According to another embodiment of the present invention, after analyzing the text data, the second control unit may control to display information related to the analyzed conversation content together with or in place of the text data.

For example, FIG. 10 is an exemplary diagram of displaying text data received from a first mobile terminal and information related to analyzed conversation contents.

For example, as in the example illustrated in FIG. 10, if the analyzed conversation contents include a name for identifying a specific person (illustrated as Karen in FIG. 10), the second controller may include information of the specific person, for example, The phone number of a specific person and a group to which a specific person belongs in the phone book may be displayed. As another example, as in the example illustrated in FIG. 10, if a analyzed place includes a specific place (illustrated as Cheongdam-dong in FIG. 10), the second controller may control to display map data corresponding to the specific place. Can be. In addition, the second control unit may display traffic information related to the contents of the conversation or control price information of the article related to the contents of the conversation.

The second control unit according to the present invention may control to selectively display any one of the content list and the text data to be shared with the call counterpart or control the both to be displayed at the same time. If both are set to be displayed at the same time, the second controller divides the second touch screen into two areas, displays a list of contents to be shared with the call partner through the first area, and through the second area. It may be possible to control the text data to be displayed.

Referring back to FIG. 6, the second controller analyzes the text data received from the first mobile terminal 200, and based on the analysis result of the text data, the second control unit selects contents related to the conversation contents among the contents to be shared with the call counterpart. The extracted content list may be displayed (S605).

In displaying the content list, the second controller may display the content list associated with the conversation content in a separate group. FIG. 11 is an exemplary diagram for describing displaying content associated with a conversation content in a separate group. In FIG. 11, the type of content to be shared with the call counterpart is illustrated as an image. As an example, when the analysis result of the text data indicates that a specific place is included in the conversation contents, the second controller extracts a photo taken at a specific place among the contents to be shared with the caller, and the example shown in FIG. Likewise, the image list extracted into the separate group 1110 may be displayed.

For example, if the conversation contents were 'weather was good when I went to Namsan', the second controller extracts a geographical name 'Namsan' from the conversation contents, extracts an image taken from 'Namsan' among the images, and extracts the extracted image. The list of images can be displayed as a separate group.

As another example, when a meaning corresponding to a specific time such as a specific date or a specific day is extracted from the conversation contents, the second controller may extract the image photographed at a specific time and display the extracted image as a separate group. . Furthermore, when a name for identifying a specific person (for example, the name of a specific person or an SNS account of the specific person, etc.) is extracted from the conversation, the second controller extracts an image of the specific person and extracts the extracted image. It may be displayed as a separate group.

Unlike in the example shown in FIG. 11, the second controller displays only the content list associated with the conversation content, or uses the association with the conversation content as a sorting criterion of the content list so that the content associated with the conversation content in the content list is preferentially exposed. In addition, it is possible to control that the content not related to the conversation content is exposed in a lower order.

In FIG. 11, the type of content to be shared with the call counterpart is illustrated as an image, but the same principle may be applied to not only an image but also other types of content. For example, when the content to be shared with the caller is schedule data, the second controller extracts and displays a schedule held at a place extracted from the conversation contents, or extracts and displays a schedule scheduled at a time extracted from the conversation contents. You may.

At any time while the content list is being displayed, if at least one content of the content list is selected and a user input for sharing the selected content with the call partner is input (S606), the second controller returns to the first mobile terminal 200. The user may request to share the selected content with the call counterpart (S607).

In this case, if the selected content is stored in the second mobile terminal 300, the second controller may request sharing with the call counterpart while transmitting the selected content to the first mobile terminal 200. On the contrary, if the selected content is stored in the first mobile terminal 200 or a cloud server that is used in common with the first mobile terminal 200, the second controller transmits identification information of the selected content to the first mobile terminal 200. Will be able to provide

The user input for sharing the selected content with the call counterpart may be implemented in various forms. 12 is an exemplary diagram for explaining an example of a user input. After at least one of the list of contents shown in FIG. 12A is selected, the second controller sets at least a portion of the second touch screen as a sharing area 1210 for requesting sharing with a call counterpart, The set sharing area 1210 may be displayed. Thereafter, as shown in the example of FIG. 12B, when dragging the selected content to the sharing area 1210, the second controller can request to share the selected content with the call counterpart.

In the example of FIG. 12, the second controller may be set to display the sharing area only while the pointer is in contact with the touch screen. In this case, the second controller may be set so that the position of the sharing area does not overlap with the touch position of the pointer.

The example illustrated in FIG. 12 illustrates an example of a user input for sharing the selected content with the counterpart, and is not intended to limit the present invention. Unlike in the example shown in FIG. 12, the user input may include: i) selecting at least one of the content to be shared with the called party, and then touching a button for requesting sharing with the called party, ii) sharing with the calling party. After selecting at least one of the desired content, the content may be flickered in a predetermined direction.

Although FIG. 6 illustrates that step S606 is performed after step S605, step S606 may occur at any time while the content list is displayed.

As shown in the example of FIG. 12, if a user input requesting sharing with a call counterpart is input in a state where a specific content is displayed, instead of displaying a content list, the second control unit displays through a second touch screen. The first mobile terminal 200 may request the specific content being requested from the call counterpart.

For example, FIG. 13 is an exemplary diagram illustrating a user input for sharing specific content displayed on a second touch screen with a call counterpart. As shown in the example of FIG. 13, if the 'share with call partner' button 1310 is touched while the specific content is being displayed on the second touch screen, the second controller may control the first mobile terminal 200. As a result, the user may request to share the specific content being displayed through the second touch screen with the call counterpart.

The second mobile terminal 300 according to the present invention displays a list of contents to be shared with the call counterpart, accesses the user's SNS account, and extracts a post related to the call counterpart from the posts uploaded to the SNS server. It can also be displayed. Referring to FIG. 14, the access screen of the SNS account and the list of contents to be shared with the call partner are simultaneously displayed.

FIG. 14 is an exemplary view illustrating simultaneous display of a connection screen of an SNS account and a list of contents to be shared with a call counterpart. For convenience of description, the type of content to be shared with the call counterpart is illustrated as an image.

As in the example shown in FIG. 14, the second controller divides the second touch screen into two areas 1410 and 1420, and accesses to the SNS account and the second area through the first area 1410. In operation 1420, the list of contents to be shared with the call counterpart may be displayed.

In this case, in displaying the access screen to the SNS account in the first area 1410, the second controller may include a post (eg, a post including an image taken with the call counterpart) related to the call counterpart among posts uploaded to the SNS server. , A post in which the call counter has left a reply, a post including a content related to the call counter), and the like, may be controlled so that only the extracted post is output to the first area 1410.

In displaying the content list to be shared with the call counterpart in the second area 1420, the second controller controls the content list associated with the call counterpart to be displayed, as in the example illustrated in FIGS. 8 and 11. It is also possible to control the display of the content list associated with the conversation contents.

Subsequently, when a user input of dragging at least one content of the content list displayed in the second area 1420 to the first area 1410 occurs, the second control unit drags the content to the first area 1410. The controlled content can be uploaded to the user's SNS account. Accordingly, the user can easily upload the content associated with the call counterpart or the content associated with the conversation content to the SNS account.

If a specific content is displayed through the second area 1420 and a drag input is generated from the second area 1420 to the first area 1410, the second control unit determines that the specific content is the SNS account of the user. Will be controlled to be uploaded to.

When the distance from the first mobile terminal 200 is less than or equal to the preset distance, when the first mobile terminal 200 receives the content from the call counterpart at any time, the second mobile terminal 300 is the first mobile terminal 200. In operation S608, the first mobile terminal 200 may receive content received from the call counterpart. When the content is received from the first mobile terminal 200, the second controller may control the content received from the first mobile terminal 200 to be displayed (S609). Accordingly, the user may be provided with the convenience of confirming the content transmitted by the call counterpart to the second mobile terminal 300 while continuing the telephone call to the first mobile terminal 200.

2 and 6, after the communication channel is established with the first mobile terminal 200 and the second mobile terminal 300, the separation distance between the first mobile terminal 200 and the second mobile terminal 300 is preset. It was determined whether or not the distance. In contrast, the first mobile terminal 200 and the second mobile terminal 300 may establish a communication channel when the mutual separation distance is less than or equal to a preset distance. In this case, the predetermined distance between the first mobile terminal 200 and the second mobile terminal 300 may be set to a range in which short-range communication is possible.

According to the above-described embodiment, when the first mobile terminal 200 having a phone call is located close to the second mobile terminal 300, the second mobile terminal 300 specifies the sharing counterpart of the content as the call counterpart. . Accordingly, the user is provided with the convenience of directly designating the other party as the content sharing target without the hassle of searching for the target to be shared.

According to one embodiment of the present invention, the above-described method (operation flowchart) can be embodied as processor readable code on a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.
