Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

For convenience of explanation, it is assumed that the mobile terminal 100 described in the present invention includes at least one of the components shown in Figs. 1A to 1C. For example, in the following embodiments, the mobile terminal 100 includes a wireless communication unit 110, a microphone 122, a display unit 151, a memory 170, Lt; RTI ID = 0.0 > 180 < / RTI >

Since the mobile terminal 100 according to the present invention can be more easily implemented when the display unit 151 is a touch screen, it is assumed herein that the display unit 151 is a touch screen. When the display unit 151 is not a touch screen, the touch input in the embodiment described later may be replaced by an input for pushing a button, a gesture input using the mobile terminal 100, a voice command, or the like.

2 is a flowchart illustrating an operation of the mobile terminal 100 according to an exemplary embodiment of the present invention. The control unit 180 activates the microphone 122 (S202), and the microphone 122 (122) activates the microphone 122. When the mobile terminal 100 determines that the user wants to use the mobile terminal 100, (S203). In this case, it is determined whether a user using the mobile terminal 100 is in a conversation state.

For example, when the mobile terminal 100 is unlocked, an application is executed, a user input for confirming a received message is received, and a user input for inputting a text is received (For example, when creating a message to be created in a predetermined counterpart) or when the user brings the mobile terminal 100 to the face (for example, when the face of the user is recognized through the front camera) 100) is to be used.

In addition, the predetermined event is an event when a message (e.g., a text message, an instant message) is received from the mobile terminal 100, an incoming call is received, or a notification from a specific application (for example, (For example, when an alarm is output when the current time reaches the predetermined alarm time, or when the current time is a predetermined time when a predetermined schedule starts, When an alarm is output).

In addition, the predetermined event may include a case of confirming the above case, not when a message, notification is received, or when an alarm is output, as described above. For example, after a message is received, a user may touch an area associated with the message reception to confirm the contents of the message. As another example, after an advertisement for a specific application is received, a predetermined event may include a user touching an area related to the notification reception in order to enter and confirm the contents of the notification into the application.

If the user is not conducting a conversation, the control unit 180 may deactivate the microphone 122 (S207).

Specifically, if the voice is not input to the microphone 122 or the voice is input although a predetermined time has elapsed, but the voice is not input, the control unit 180 determines that the user is not proceeding with the conversation .

On the other hand, if it is determined that the user is proceeding with the conversation, the control unit 180 converts the voice of the conversation participants input into the microphone 122 into text (S204) (S205).

Specifically, the control unit 180 analyzes the voice input to the microphone 122, and can determine that the user is conversing when two or more persons are input within a predetermined time.

In order to prevent confusion with the TV sound or the other human conversation sounds around the user even when two or more persons are input, the control unit 180 determines that the user is in conversation . To do this, the user's voice samples need to be registered in the memory 170 in advance. The control unit 180 may compare the voice inputted through the microphone 122 and the voice sample of the registered user so as to judge whether two or more voice including the user is being input.

In the above example, it is assumed that the user is in conversation only when two or more persons are input within a predetermined time. Alternatively, the control unit 180 may determine that the user is in conversation even when one voice is input within a predetermined time.

3 is a diagram showing an example in which conversation contents converted into text are outputted.

When a message is received from a predetermined counterpart, the controller 180 notifies the status bar 310 indicating the status of the mobile terminal 100 that the message has arrived, as in the example shown in FIG. 3 (a) It is possible to control the indicator 312 to be outputted.

Then, when an area 320 notifying that a new message has been received is touched on the notification area output as the pointer moved by dragging the pointer on the status bar 312 in a predetermined direction (see FIG. 3B) The control unit 180 may control the chat window to output a chat window for confirming a message received from a predetermined counterpart, as in the example shown in FIG. 3C.

At this time, the control unit 180 activates the microphone 122, and can determine whether the user is talking on the basis of the voice input through the microphone 122. If it is determined that the user is in conversation, the control unit 180 may control to output information indicating that the conversation contents of the user are to be recorded. In FIG. 3 (c), a message 330 indicating that the conversation contents of the user will be recorded is output.

3 (d), the control unit 180 may convert the voice of the conversation participants input through the microphone 122 into text, and control the converted text to be displayed. At this time, a dialog window for displaying the conversation contents of the conversation participants may be overlaid on the chat window being output through the display unit 151. [ At this time, the control unit 180 may control the dialog window to be displayed in a translucent manner in order to prevent the dialog window from covering the chat window being output through the display unit 151. [

The control unit 180 may display only the main keywords of the conversation contents instead of displaying the entire conversation contents. For example, FIG. 3 (e) shows an example of outputting a main keyword among conversation contents. As in the example shown in FIG. 3 (e), the control unit 180 may control to display only key keywords such as subject, object or predicate omitted from the conversation contents of the user.

Although not shown, if the conversation continues for a long time and the entire conversation contents can not be displayed through the display unit 151, the control unit 180 preferentially displays the latest conversation contents among the entire conversation contents, The user can control to display the remaining conversation contents through the conversation window when the user input is received.

In outputting the result of converting the contents of the conversation into text, the control unit 180 can control the contents of conversation for each participant participating in the conversation to be identified and displayed.

For example, FIG. 4 shows an example in which conversation contents per participant are identified and displayed. The control unit 180 may analyze the frequency component of the voice input to the microphone 122 to distinguish each participant participating in the conversation.

Accordingly, when displaying the conversation contents, the control unit 180 can control to output an image representative of the participants mapped to the conversation contents. In FIG. 4 (a), a predetermined image representative of a participant mapped to each conversation is illustrated as being output.

The control unit 180 compares the pre-stored speech samples corresponding to the speech input through the microphone 122, and if the speech sample coincides with the speech input to the microphone 122 is found, So that the information of the person is displayed. For example, in FIG. 4B, it is illustrated that the information (participants' names and photographs) 410 of the participants participating in the conversation is displayed.

If no voice sample matching the voice input to the microphone 122 is found, the control unit 180 determines that no person matching the voice is found as in the example shown in FIG. 4 (b) It is possible to control the image 420 indicating the sound to be outputted. At this time, if the corresponding image (that is, the image indicating that the person matching the voice is not found) 420 is touched, the control unit 180 displays the voice corresponding to the voice as shown in (c) And a user registration menu for registering a user mapped to the user. Although not shown, when the corresponding image (that is, the image indicating that no person matching the voice is found) is touched, the control unit 180 controls to select the corresponding person in the previously registered phone book You may.

It is illustrated through the user registration menu of FIG. 4 that the name of the user, the telephone number of the user, the photograph of the user, and the like can be additionally inputted.

5A and 5B are diagrams showing another example in which conversation contents per participant are identified and displayed. The control unit 180 may control the display of the conversation contents of each participant so that the conversation contents of each participant are identified and displayed.

For example, when it is assumed that three participants are participating in the conversation, the control unit 180 arranges and displays one of the conversation contents on the left side of the display unit 151 as in the example shown in FIG. 5A (512 The other conversation contents are arranged and displayed on the right side of the display unit 151 in step 514 and the remaining conversation contents are arranged in the center of the display unit 151 and displayed 516, It can be controlled to be identified and displayed.

The control unit 180 may determine the display position of the conversation contents for each participant based on the actual position of the participant. For example, as in the example shown in FIG. 5B, the voice of the user is input in the downward direction with respect to the display direction of the display unit 151 of the mobile terminal 100, (B) of FIG. 5B, when it is assumed that the display unit 151 is positioned in the upper right direction or the right direction and the upper left direction or the upper left direction with respect to the display direction of the display unit 151 of the display unit 100, The conversation contents 524 of the participant Lin positioned in the upper right direction or the right direction are displayed on the upper right side of the display unit 151 And the conversation contents 522 of the participant John positioned in the left upper direction or the left direction can be displayed on the upper left of the display unit 151. [

Although not shown, the controller 180 may distinguish and display the conversation contents per participant by changing the color or size of the conversation contents per participant.

The control unit 180 can change the display position of the dialog window based on the user input. For example, when an input to which a pointer that touches a dialog window is dragged is received, the control unit 180 may control the dialog window to move along the movement trajectory of the pointer. At this time, when a part of the dialog window is moved out of the display unit 151 as the dialog window moves, the control unit 180 may hide the dialog window and control to display an object capable of resuming the display of the dialog window.

For example, FIG. 6 shows an example in which a dialog window is hidden. As shown in FIG. 6A, when a user input to which a pointer is dragged and moved by touching a dialog window is received, the control unit 180 controls the display position of the dialog window to be changed along the trajectory of dragging and moving the pointer Can be controlled. 6 (b), when a part of the dialog window is moved out of the display unit 151, the controller 180 displays the dialog window, as in the example shown in FIG. 6 (c) The display can be stopped. The control unit 180 can control to display the object 610 capable of resuming the display of the dialog window while stopping the display of the dialog window.

When the object 610 for resuming the display of the dialog window is touched, the control section 180 can control the dialog window 620 to be displayed again at a predetermined position, as in the example shown in Fig. 6 (d) have.

6 illustrates an example of a user input to move the dialog window, a drag input by a single pointer is illustrated, but a drag input by a plurality of pointers or a touch input by a pointer touching the display unit twice (for example, The input is for selecting a dialog window, and the second touch input is for determining the position to move the dialog window) can also be utilized as a user input to move the dialog window.

In the example shown in FIGS. 3 to 6, the dialog window on the job window being output through the display unit 151 is illustrated as being overlaid. 3 to 6 illustrate that the task window being output through the display unit 151 is a chat window for displaying chat contents with a predetermined other party. However, while a home screen screen or various screens generated during application execution are displayed, It is a matter of course that the window can be output.

The control unit 180 may divide the display unit 151 into two areas and then control the contents of the dialog to be displayed through any one area.

For example, FIG. 7 shows an example in which the display unit 151 is divided into two regions. The control unit 180 determines whether the display unit 151 has two areas I, I, II, and I, as in the example shown in FIG. 7, when it is determined that the user is in conversation at the time of receiving the user input for confirming the received message. II). ≪ / RTI > At this time, a chat window for confirming the received message is outputted through one area I, and conversation contents can be outputted through another area II.

As another example, the control unit 180 may control to output the conversation contents only when a user input for browsing the conversation contents is received.

For example, FIG. 8 shows an example in which conversation contents are displayed as user input is received. When it is judged that the user is in conversation at the time when the user input for confirming the received message is received, the control unit 180 determines whether the user is currently engaged in chatting for confirming the received message, as in the example shown in FIG. While displaying the window, you can record the conversation in the background. In order to inform that the conversation contents are being recorded in the backward line, the control unit 180 can control so that information indicating that the conversation contents are being recorded is outputted. In FIG. 8A, it is exemplified that a message 810 indicating that the conversation contents of the user is being recorded is output. Although not shown, by displaying a predetermined indicator on the status bar, it can be notified that the conversation contents are being recorded.

Then, when a user input for confirming the conversation contents is received (for example, a message 810 indicating that the conversation contents are being recorded is touched), the control unit 180, as in the example shown in FIG. 8B, , And the recorded conversation contents 820 are displayed. As described with reference to FIGS. 3 to 6, the control unit 180 may control the dialog window in which the dialog content is recorded to be displayed on the operation window being overlaid on the display unit 151. However, as shown in FIG. 8B, As in the example, it is possible to control the dialog window to be displayed on the full screen by replacing the previously displayed task window.

When at least some of the conversation contents included in the conversation window are selected and the selected conversation contents are dragged to the operation window, the control unit 180 can control the selected conversation contents to be applied to the dragged operation window.

For example, FIG. 9 shows an example in which some of the conversation contents included in the conversation window are copied to the operation window.

When some of the conversation contents output through the conversation window are selected and the selected conversation contents are dragged to the operation window, the control unit 180 can control the conversation contents to be applied to the operation window.

For example, as in the example shown in FIG. 9A, when some of the conversation contents are dragged to a chat window for outputting chat contents with a predetermined counterpart, It is possible to control so that the dragged dialogue contents are input to the text input window 910 for inputting the contents of the message to be transmitted to the predetermined counterpart.

Through this, the user can quickly transmit the conversation contents displayed through the conversation window to the chatting party.

At this time, the control unit 180 can also control the information of the conversation participant who referred to the dragged dialogue content to be displayed on the text input window. For example, when the participant who referred to the dragged conversation content is 'Lin', the control unit 180, as in the example shown in (c) of FIG. 9, Lin 'of the participant can be displayed on the text input window 910.

9 illustrates an example of a user input to which text included in a dialog window is to be applied to another task window, a drag input by a single pointer is illustrated, but a drag input by a plurality of pointers or a touch that the pointer touches the display unit twice The input (for example, the first touch input is for selecting text included in the dialog window, and the second touch input is for selecting a task window to which the selected text is to be applied) It can be used as a user input to be applied to a task window.

The dialog window can display the information of participants participating in the conversation as described above with reference to FIG. At this time, if at least one of the participants participating in the conversation is selected and information of the selected participant is dragged and moved in the chat window, the control unit 180 can invite the participant to the chat window.

For example, FIG. 10 illustrates an example in which a participant participating in a conversation is invited to a chat window in which a conversation is in progress with a predetermined recipient.

If the user is in the process of conversation at the time of outputting the chat window for chatting with the predetermined counterpart, the control unit 180 may include the conversation contents of the user on the chat window, as in the example shown in FIG. 10 (a) Can be controlled so that the dialog window is overlaid. At this time, if there is a voice sample matching the voice inputted through the microphone 122, the controller 180 may control the display of the information of the person matched to the found voice sample.

At this time, when the information of the participant participating in the conversation is touched (for example, the image or the name representing the participant) and the pointer inputting the participant's information is dragged and moved in the chat window, It is possible to invite the corresponding participant (specifically, the participant's terminal) to the corresponding chat room, as in the example shown in (b) of FIG.

Thus, by inviting the chat room to a chat room in a chat room for chatting with a predetermined party, the three persons participating in the chat room can continue the conversation through the message.

10 illustrates an example of a user input to invite a person participating in a conversation to a chat window, a drag input by a single pointer is illustrated, but a drag input by a plurality of pointers or a touch input by a pointer twice touching the display unit For example, the first touch input is for selecting a person participating in a conversation, and the second touch input is for selecting a chat window to invite a selected person), and the like. It can be used as a user input to be applied.

Further, the mobile terminal 100 according to the present invention may apply a combination of the embodiments shown in Figs. 9 and 10, for example, a drag input by a single pointer (or a plurality of pointers) The drag input by a plurality of pointers (or a single pointer) is for applying the text contained in the dialog window to the text input window, as in the example shown in FIG. 10, It may be to invite a person to a chat window.

2, when the user determines to use the mobile terminal 100 or when a predetermined event occurs in the mobile terminal 100, the microphone 122 is activated and the voice input through the microphone 122 is activated. And when the user is judged to be in conversation, it is exemplified that the result of converting the voice of the conversation participants into text is outputted.

In contrast to the illustrated example, when the predetermined user input is received through the mobile terminal 100, the control unit 180 converts the voice of the conversation participants input via the microphone 122 into text in response to the user input So that the result is outputted.

11A and 11B are diagrams showing an example in which conversation contents are displayed in response to user input.

When the predetermined user input is received during the use of the mobile terminal 100 (for example, in FIG. 11A, a user input for dragging the status line from left to right is illustrated as being received) 122, and controls the conversation contents converted from the voice of the conversation participants input through the microphone 122 into text, as in the example shown in (b) of FIG. 11A.

When a predetermined user input is received during the use of the mobile terminal 100 (for example, in FIG. 11 (a), the user input for dragging the pointer from the lower end to the upper end of the display unit 151 is illustrated as being received) 180 can control the menu to be displayed as in the example shown in Fig. 11B (b). 11B, a button 1102 for activating the microphone 122, a button 1104 for searching for data stored in the mobile terminal 100, and a button for inputting a handwriting to the mobile terminal 100 (1106) is output.

When the button 1102 for activating the microphone 122 is touched in the menu shown in Fig. 11B, the controller 180 activates the microphone 122, As shown in the example, it is possible to control the output of the conversation contents converted from the voice of the conversation participants input through the microphone 122 into text.

If the preset sound is input during recording of the conversation contents or it is determined that the user will no longer use the mobile terminal 100 or if the event that has occurred ends (S206), the control unit 180 controls the microphone 122 (S207), thereby stopping the recording of the conversation contents.

Here, the preset sound may be a sound generated as a result of a gesture performed by the user such as a clapping sound, or a voice for a specific keyword such as 'end', 'sorry', and the like.

When the mobile terminal 100 is switched to the power saving mode (for example, when a user input for transferring the mobile terminal 100 to the power saving mode is received), the controller 180 terminates It may be determined that the user will not use the mobile terminal 100 any longer, for example, when the message transmission to the predetermined counterpart is completed or when the face of the user is not recognized through the front camera.

In addition, the control unit 180 can determine that the event is terminated when the message received from the mobile terminal 100 is confirmed, when the telephone call is terminated, or when the alarm output is terminated.

When it is desired to interrupt the recording of the conversation contents as the preset sound is inputted, the control unit 180 can control to output a message indicating that the recording of the conversation contents will be stopped soon. At this time, the controller 180 deactivates the microphone 122 and stops recording the conversation contents when a predetermined time elapses after the message is output. On the other hand, if the user receives the user input within a predetermined time after the message is output, It is possible to cancel the command for ending the recording of < / RTI > This is to prevent the interruption of the recording of the conversation contents due to the unintentional input of the preset sound.

For example, FIG. 12 illustrates an operation of the mobile terminal 100 when a preset sound is input while the conversation contents are displayed.

When a preset sound (for example, an applause sound) is input while the dialogue content is being displayed through the dialog window, the control unit 180, as in the example shown in FIG. 12 (a) , And a message 1220 indicating that the display of the conversation contents is to be stopped may be output.

The control unit 180 cancels the command for stopping the display of the dialog window 1210 and displays a message indicating that the user has touched the display of FIG. As in the example shown in b), the display of the dialog window 1210 may continue. Thus, the conversation contents in which the voice inputted through the microphone 122 is converted into text, can be displayed continuously in the conversation window.

Alternatively, if the user's touch input has not been received for a predetermined time since the message was output, the control unit 180 deactivates the microphone 122 and, as in the example shown in FIG. 12C, The display of the dialog window 1210 can be stopped. At the same time, the control unit 180 can control to output a message indicating that the recording of the conversation contents has been stopped.

The control unit 180 can store the conversation contents from the time point when the recording of the conversation contents is started to the point when the recording has ended. For example, when the conversation contents are stored in the text file format, the control unit 180 may view the conversation contents stored later through the memo application or the document viewer application.

In addition, the control unit 180 may store the voice file recorded with the conversation contents. In this case, the control unit 180 can control the link for accessing the voice file to be included in the text file in which the conversation contents are recorded. In addition, the control unit 180 may control to display the stored conversation contents when the voice file is reproduced.
