In the following embodiments, 'first' is added to the components of the first mobile terminal 200 and 'second' is added to the components of the second mobile terminal 300 for convenience of explanation. Is added.

In addition, when the first mobile terminal 200 and the second mobile terminal 300 are touch screens, the first mobile terminal 200 and the second mobile terminal 300 ) Is assumed to be a touch screen.

A user 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' Or a user thereof is also referred to as a " calling party ".

Hereinafter, operations of the first and second mobile terminals 200 and 300 according to the present invention will be described in detail with reference to the drawings.

4 is a flowchart illustrating an operation of a first mobile terminal according to an exemplary 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). A local communication technique may be used to establish a communication channel between the first mobile terminal 200 and the second mobile terminal 300. Specifically, local communication technologies such as Bluetooth, ZigBee, IEEE 802.11x, and Wi-Fi Direct may be used.

For example, FIG. 5 is an exemplary diagram illustrating how a first mobile terminal and a second mobile terminal are paired with each other via Bluetooth. 5, when the first mobile terminal 200 requests pairing with the second mobile terminal 300 based on the user input, the second control unit 300 of the second mobile terminal 300, A popup window 510 for determining whether to accept the pairing request of the first mobile terminal 200 is displayed. A communication channel between the first mobile terminal 200 and the second mobile terminal 300 may be established according to a user input to the pop-up window 510. [

In a state where a communication channel is established between the first mobile terminal 200 and the second mobile terminal 300, the first mobile terminal 200 can initiate a telephone conversation with an arbitrary party (S402). Here, the telephone conversation between the first mobile terminal 200 and the arbitrary party may include various types of communication methods such as voice call, video call, and VoIP call.

If the distance between the first mobile terminal 200 and the second mobile terminal 300 is narrowed to a predetermined distance or less in step S403 while the mobile terminal is in a telephone conversation with the other party, The second mobile terminal 300 can provide a content list to be shared with the other party at the request of the terminal 300 (S404). Here, the predetermined distance may be fixed to a specific value (for example, 2 m) but may be set to be changed by the user (for example, 2 m is changed to 3 m). The first control unit may measure a separation distance from the second mobile terminal 300 by using a sensor device such as a proximity sensor or a distance sensor. However, based on the intensity of a 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 stored in the first memory but the content stored in the second mobile terminal 300 or the content stored in the first mobile terminal 200 or the cloud server commonly used by the second mobile terminal 300 In the case of the uploaded content, the step of providing the content list to the second mobile terminal 300 may be omitted. Otherwise, if at least a part of the content stored in the first memory is included in the category of the content to be shared with the other party, the first control unit may 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, instead of transmitting the content itself to be shared with the other party, the first controller may transmit thumbnails Or a preview image) can be transmitted. If a request for transmission of at least one of the content list is received from the second mobile terminal 300, the first controller may 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 other party among the content stored in the first memory, and then selects the thumbnail (or preview image) of the selected content Content list may be provided to the second mobile terminal 300. For example, a captured image or a moving picture, a schedule with the calling party, and a memo recorded with a name identifying the calling party may be included in the category of the content associated with the calling party.

The first control unit may further provide converted text data converted into text (Speech to Text) (STT) from the voice signal generated during the telephone conversation to the second mobile terminal 300 (S405). At this time, the first control unit may transmit to the second mobile terminal 300 both the converted text based on the uttered voice and the converted text based on the voice uttered by the user, The text converted based on the uttered voice and the text converted based on the voice uttered by the user may be provided to the second mobile terminal 300. Whether to provide the two texts to the second mobile terminal 300 or to provide only either of them can be adjusted based on the setting value stored in the first memory and the setting value can be manually adjusted by the user It is possible.

However, the step of transmitting text data to the second mobile terminal 300 is not necessarily an essential step to be performed. In some cases, the step of transmitting text data to the second mobile terminal 300 may be omitted. Further, the step of providing the text data to the second mobile terminal 300 does not necessarily have to be performed after the step of providing the content list. The step of providing text data to the second mobile terminal 300 may be performed prior to or simultaneously with the step of providing the content list.

When the second mobile terminal 300 requests the second mobile terminal 300 to share predetermined content with the second mobile terminal 300 in step S406, the first controller transmits the content requested by the second mobile terminal 300 to the called party, And the content is shared (S407).

In order to allow the communication partner and the user to acquire the same user experience (that is, in order to allow the user to enjoy the same content) in the case of transmitting the content to be shared to the calling party at the request of the second mobile terminal 300 ), The second mobile terminal 300 can output the content transmitted to the calling party. The content transmitted to the calling party is outputted through the second mobile terminal 300 rather than the first mobile terminal 200 so that the user continues the telephone 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 contents shared with the calling party involve the output of sound signals such as music or moving pictures, the first control unit can adjust the volume of the contents so as not to interfere with the telephone conversation. For example, when the size of the first micro-input sound signal exceeds a predetermined allowable value or is equal to or greater than a predetermined level with respect to the voice volume during a telephone call, the first controller transmits the output volume of the content to the second mobile terminal 300 By controlling the control command, the output volume of the content can be controlled to be automatically reduced.

The first mobile terminal 200 receives a request from the second mobile terminal 300 to request content sharing to the calling party, and conversely, the first mobile terminal 200 may request sharing of the content from the calling party. In a case where the content for sharing is received from the communication partner in a state where the distance from the second mobile terminal 300 is set to a predetermined distance or less (S408), the first controller transmits the content received from the communication partner to the second mobile terminal (S409). By controlling the received content to be outputted through the second mobile terminal 300, the user can check the received content without detaching the first mobile terminal 200 from the ear to check the first touch screen .

If the content for sharing is received from the second mobile terminal 300 in a state where the distance from the second mobile terminal 300 is greater than a predetermined 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 distance from the second mobile terminal 300 is less than a predetermined distance, 2 mobile terminal 300 according to the control information.

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

6 is a flowchart illustrating an operation of a second mobile terminal according to an exemplary 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). If it is determined that the distance between the first mobile terminal 200 and the first mobile terminal 200 in a telephone conversation state is less than a predetermined distance in a state where a communication channel with the first mobile terminal 200 is established (S602) 200) and a content list to be shared with the calling party (S603).

FIG. 7 shows a screen output change of the second mobile terminal when it is determined that the distance from the first mobile terminal in a telephone conversation is less than a predetermined distance. 7 (a) illustrates the output of the second mobile terminal 300 before the distance from the first mobile terminal 200 is narrowed to a predetermined distance or less, and FIG. 7 (b) And the output of the second mobile terminal 300 after the distance from the terminal 200 is narrowed to a predetermined distance or less.

7A and 7B, when the distance from the first mobile terminal 200 is narrowed to a predetermined distance or less, the second control unit is operated through the second touch screen It is possible to control the output of the content list to be shared with the calling party. In FIG. 7 (b), an image, a schedule, and a memo item are illustrated as types of contents to be shared with a communication partner. The second control unit may simultaneously output various types of content lists, as in the example shown in FIG. 7B, but may output only one type of content list. For convenience of drawing, it is assumed that a list of any type of content is displayed on the second touch screen in the following drawings.

As in the example shown in Figs. 7 (a) and 7 (b), prior to switching the output of the second mobile terminal 300, , A pop-up window for inquiring whether or not to switch the output of the second mobile terminal 300 can be output. The second control unit can determine whether to display the content list to be shared with the calling party based on the user input for the pop-up window shown in (c) of FIG.

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 the cloud server shared by the first and second mobile terminals 200, ≪ / RTI > The second mobile terminal 300 may receive the content list from the first mobile terminal 200 or the cloud server in order to display the content list stored in the first mobile terminal 200 or the content list stored in the cloud server .

In displaying the content list, the second control unit may control only the content associated with the calling party to be exposed in the content list. Here, the content related to the calling party may be an image or video captured by the calling party, a schedule associated with the calling party (for example, schedule data recording an appointment with the calling party) and a note associated with the calling party The memo data in which the name of the other party or the telephone number of the other party of the call) is written. The second control unit can receive information of the calling party from the first mobile terminal 200 in order to extract the content related to the calling party and display only the content in order to display the extracted content list. Here, the information of the calling party may include an image of the calling party, a name (e.g., a name, an SNS (Social Network Service) account, etc.) for identifying the calling party, and a telephone number of the calling party. As another example, when displaying the list of contents, the second control unit may extract the content associated with the calling party and display the extracted content in a separate group. Referring to FIG. 8, a method of displaying a content list associated with a calling party will be described in more detail.

8 is an exemplary diagram illustrating a method of displaying content associated with a calling party. For convenience of explanation, it is assumed that the content to be shared with the calling party is an image.

Fig. 8 (a) shows a virtual state of the communication party. The second control unit extracts an image of the same person as the communication partner shown in (a) of FIG. 8, and displays the list of captured images of the calling party as shown in FIG. 8 (b) Can be controlled.

As another example, the second control unit may display a list of contents, as in the example shown in (c) of FIG. 8, while displaying the photographed images as a separate group 810. In either case, the user can easily recognize the content associated with the calling party.

Referring again to FIG. 6, the second mobile terminal 300 may receive text data from the first mobile terminal 200 in the telephone conversation (S604). Here, the text data may be data obtained by converting a voice signal generated during a telephone conversation into text, and converting at least one of the voice uttered by the calling party and the voice uttered 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 control unit transmits the text data generated based on the voice uttered by the user and the text data generated based on the voice uttered by the calling party It may request the first mobile terminal 200 to transmit at least one. Whether or not to request either can be adjusted according to the setting value stored in the second memory, and the setting value can be manually adjusted by the user.

The second control unit may display the text data received from the first mobile terminal 200 in real time, but it is not necessarily displayed. If the text data received from the first mobile terminal 200 is displayed, even if the voice of the calling party is not correctly recognized, the message to be transmitted by the calling party through the output of the second touch screen can be recognized.

9 is a diagram illustrating text data output to the second mobile terminal. As in the example shown in FIG. 9A, the second control unit can control the display of the text data received from the first mobile terminal 200. FIG. At this time, if a specific word in the conversation contents is repeated a predetermined number of times or more, the second control unit can control to highlight a specific word repeated a predetermined number of times or more as in the example shown in FIG. 9B.

According to another embodiment of the present invention, the second control unit may analyze the text data and then control the information related to the analyzed content to be displayed together with or in addition to the text data.

For example, FIG. 10 is an example of display of text data received from the first mobile terminal and information related to the analyzed conversation contents.

For example, as in the example shown in Fig. 10, if the analyzed conversation contents include a name for identifying a specific person (which is exemplified as karen in Fig. 10), the second control unit may acquire information of a specific person, A telephone number of a specific person, a group to which a specific person in the telephone book belongs, and the like can be displayed. As another example, if the analyzed conversation content includes a specific place (exemplified by Cheongdam-dong in Fig. 10) as in the example shown in Fig. 10, the second control unit controls the map data corresponding to the specific place to be displayed . In addition, the second control unit may display traffic information related to the conversation contents, or control price information and the like for the articles related to the conversation contents to be displayed.

The second control unit according to the present invention may control to selectively display either the content list or the text data to be shared with the calling party, or both the content list and the text data to be simultaneously displayed. If both are set to be displayed simultaneously, the second control unit divides the second touch screen into two areas, displays a content list to be shared with the other party through the first area, and displays the content list through the second area So that text data can be controlled to be displayed.

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, extracts the content associated with the conversation content among the contents to be shared with the calling party And the extracted content list can be displayed (S605).

In displaying the content list, the second control unit may display the content list associated with the content of the conversation in a separate group. FIG. 11 is an exemplary view for explaining that contents associated with conversation contents are displayed in separate groups. FIG. In FIG. 11, the types of content to be shared with the communication partner are illustrated with images. For example, when the text data includes a specific place among the conversation contents as a result of the analysis of the text data, the second control unit extracts a photograph taken at a specific place among the contents to be shared with the other party, Similarly, a list of images extracted into a separate group 1110 can be displayed.

For example, if the conversation contents were 'good weather when going to Namsan', the second control unit extracts 'Namsan' as a geographical name from the conversation contents, extracts images taken at 'Namsan' The image list 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 of the week, is extracted from the conversation contents, the second control unit may extract the photographed images at a specific time and display the extracted images in a separate group . Furthermore, when a name (for example, a name of a specific person or an SNS account of a specific person) for identifying a specific person is extracted from the conversation contents, the second control unit extracts the captured image of the specific person, You can display them in a separate group.

Unlike the example shown in Fig. 11, the second control unit displays only the content list associated with the conversation content, or uses the association with the conversation content as a sorting criterion in the content list, so that the content associated with the conversation content in the content list is preferentially exposed And may control content that is not related to the conversation contents to be exposed in a subordinate order.

In FIG. 11, the type of content to be shared with the other party is exemplified as an image, but the same principle can be applied to other types of content as well as a silent image. For example, when the content to be shared with the communication partner is predetermined data, the second control unit extracts and displays a schedule held at a place extracted from the conversation contents, extracts a scheduled schedule at the extracted time from the conversation contents, You may.

At least one content of the content list is selected at any time during the display of the content list, and when a user input for sharing the selected content with the counter party is input (S606), the second control unit transmits the content to the first mobile terminal 200 And request to share the selected content with the communication partner (S607).

At this time, if the selected content is stored in the second mobile terminal 300, the second controller may transmit the selected content to the first mobile terminal 200 and request sharing with the other party. Alternatively, if the selected content is stored in the cloud server used by the first mobile terminal 200 or the first mobile terminal 200, the second control unit may transmit the identification information of the selected content to the first mobile terminal 200 .

The user input for sharing the selected content with the calling party may be implemented in various forms. 12 is an exemplary diagram for explaining an example of user input. After at least one of the list of contents shown in FIG. 12A is selected, the second controller sets at least a part of the second touch screen as a shared area 1210 for requesting sharing with the other party, It is possible to display the set shared area 1210. Then, as in the example shown in FIG. 12B, when the selected content is dragged to the shared area 1210, the second control unit can request to share the selected content with the calling party.

In the example of Fig. 12, the second control unit may be set to display the shared area only while the pointer is in contact with the touch screen. At this time, the second control unit may be set such that the position of the shared area is not overlapped with the touch position of the pointer.

The example shown in Fig. 12 shows an example of user input for sharing the selected content with the other party, and does not limit the present invention. Unlike in the example shown in Fig. 12, the user input is performed by i) selecting at least one content to be shared with the communication partner, and then touching a button for requesting sharing with the communication partner, ii) Selecting at least one content to be displayed, and flicking the content in a predetermined direction.

In FIG. 6, step S606 is illustrated as being performed after step S605, but step S606 may occur at any time while the content list is being displayed.

12, when the user inputs a request for sharing with a communication partner in a state in which a specific content is displayed, rather than a state in which the content list is displayed, the second control unit displays, via the second touch screen, The mobile terminal 200 may request the first mobile terminal 200 to request the specific content to be exchanged.

For example, FIG. 13 is an exemplary view illustrating a user input for sharing a specific content displayed on a second touch screen with a communication partner. 13, when the 'Share with Counterparty' button 1310 is touched while the specific content is being displayed through the second touch screen, the second control unit transmits the ' , It may be requested to share the specific content being displayed through the second touch screen with the communication party.

The second mobile terminal 300 according to the present invention displays a list of contents to be shared with the calling party and simultaneously accesses the SNS account of the user and extracts the posts related to the calling party among the posts uploaded to the SNS server . The connection screen of the SNS account and the list of the contents to be shared with the communication partner are displayed simultaneously with reference to FIG.

FIG. 14 is an exemplary view illustrating that a connection screen of the SNS account and a list of contents to be shared with a communication partner are simultaneously displayed. For convenience of explanation, the type of the content to be shared with the calling party is exemplified as an image.

14, the second control unit divides the second touch screen into two areas 1410 and 1420, and displays a connection screen to the SNS account through the first area 1410, The control unit 1420 controls to display a list of contents to be shared with the calling party.

At this time, in displaying the connection screen to the SNS account in the first area 1410, the second control unit may transmit a post (for example, a message including an image taken with the communication partner) among the posts uploaded to the SNS server , A post including a comment left by the communication partner, a post including a content related to the communication partner, and the like), so that only the extracted post is output to the first area 1410. [

In displaying the content list to be shared with the calling party in the second area 1420, the second controller may control the display of the content list associated with the calling party, as in the example shown in FIGS. 8 and 11, The content list associated with the conversation content may be displayed.

Then, when a user input for dragging at least one content of the content list displayed in the second region 1420 to the first region 1410 occurs, the second control unit may drag the selected content to the first region 1410 Content to be uploaded to the user's SNS account. Accordingly, the user can easily upload the content associated with the conversation partner or the content associated with the conversation content to the SNS account.

If a drag input occurs from the second area 1420 to the first area 1410 while the specific content is displayed through the second area 1420, the second control part determines that the specific content is the user's SNS account As shown in FIG.

When the first mobile terminal 200 receives the content from the other party at any time when the distance between the first mobile terminal 200 and the first mobile terminal 200 is less than a predetermined distance, The first mobile terminal 200 can receive the content received from the calling party (S608). Upon receipt of the content 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 can be provided with the convenience of allowing the second mobile terminal 300 to confirm the content transmitted by the calling party, while continuing the telephone conversation with 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 distance between the first mobile terminal 200 and the second mobile terminal 300 is set to be predetermined Distance or less. Alternatively, the first mobile terminal 200 and the second mobile terminal 300 may establish a communication channel when the mutual spacing distance is less than a predetermined 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 in a telephone conversation is located close to the second mobile terminal 300, the second mobile terminal 300 specifies the shared partner of the content as the communication partner . As a result, the user is provided with the convenience of designating the shared party as a content sharing target immediately without having to search for each object to be shared.

According to one embodiment of the present invention, the above-described method (operation flow diagram) can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .
