Also, the display unit 151 may be configured as a stereoscopic display unit 151 (152) for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen. It is an image that makes you feel the same as reality space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means the parallax caused by the positions of the two separated eyes. When the two eyes see different two-dimensional images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt do.

The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

Referring to FIG. 1, proximity sensors (not shown) may be disposed in an inner area of a mobile terminal or a proximity of the touch screen, which is surrounded by the touch screen. The proximity sensor (not shown) may be provided as an example of the sensing unit 140. The proximity sensor (not shown) detects the presence or absence of an object approaching a predetermined detection surface, Refers to a sensor that detects without mechanical contact using force or infrared rays.

Examples of the proximity sensor (not shown) include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor (not shown) senses a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, .

As an example of the three-dimensional sensor, the sensing unit 140 may include a proximity sensor (not shown), a solid touch sensing unit (not shown), an ultrasonic sensing unit (not shown), and a camera sensing unit have.

A proximity sensor (not shown) measures the distance between a sensing object (e.g., a user's finger or a stylus pen) touching the touch surface and the sensing surface without mechanical contact using the force of an electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit (not shown) senses the strength or duration of a touch applied to the touch screen. For example, a three-dimensional touch sensing unit (not shown) senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit (not shown) is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasonic sensing unit (not shown) may be composed of, for example, an optical sensor and a plurality of ultrasonic sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit (not shown) includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of light change, thereby acquiring position information of the object to be sensed.

The alarm unit 154 may output a signal for notifying the occurrence of an event by using a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and the pattern of the vibration generated by the hit module 155 can be controlled by the setting of the user's selection or control unit 180. [ For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

Here, the information corresponding to the external terminal may include a unique number of the external terminal, a representative name and representative image set to correspond to the unique number, a time when the call is received, and the like.

According to an embodiment of the present invention

The control unit 180 may control the second sound output module 153b implemented as a loudspeaker to output a call sound corresponding to the call reception. Also, although not shown in the drawings, the user can be notified of the reception of the call through another type of alarm unit (vibration module, light emitting unit, etc.).

The user activates the call connection mode, that is, the call mode, using the wireless communication unit based on the touch input applied to the display unit 151 that outputs the screen information.

When the communication mode is activated, the controller 180 controls the wireless communication unit to receive a voice signal from the external terminal (S602). The voice signal may correspond to a voice of the other party (in a call mode) input to the external terminal and external noise input to the microphone 122 of the external terminal. However, the present invention is not limited to this, and the voice signal may include a sound transmitted from the external terminal to the mobile terminal (e.g., a notification sound, a notification music, a sound output by the other party, etc.).

The control unit 180 controls the display unit 151 to output a call screen when the call mode is activated. The call screen 510 may include information corresponding to an external terminal, a time duration of the call, and a graphic image to which a touch input is applied to terminate the call mode.

As shown in FIG. 5A, in the communication mode, the controller 180 controls the first sound output module 153a implemented by the receiver to output a voice signal received from the external terminal. In this case, the user may place the main body adjacent to the user's face and recognize the voice signal output to the second sound output module 153a.

During the call, the user can output not only the voice signal of the other party received from the external terminal, but also the user's voice input by the user to the microphone 122 through the second sound output module 153a.

When the call mode is activated, the display unit 151 outputs a call screen 510. The call screen 510 (see (d) of FIG. 5) includes information (representative name, unique telephone number, representative image) of the external terminal and the time during which the call progresses. A graphical image to which a touch input is applied to control termination, input of a dial, switching to speakerphone mode, activation of mute and blurt (BT).

The controller 180 controls the display unit 151 to be turned off while the display unit 151 and the face of the user are positioned close to each other . Accordingly, when the user does not see the display unit 151, unnecessary power consumption can be reduced.

The control unit 180 detects the position of the display unit 151 and the position of the user during a communication mode (S603). That is, the control unit 180 controls the sensing unit 140 to sense a change in the position of the main body of the mobile terminal moving based on the face of the user.

For example, the sensing unit may include a proximity sensor (not shown) formed on the front surface of the mobile terminal on which the display unit 151 is formed and sensing an external object disposed adjacent to the display unit 151 have. The proximity sensor (not shown) senses when the user moves the main body close to the user's face to detect a voice signal output to the first sound output module 153a in the call mode.

The sensing unit 140 may further include an acceleration sensor (not shown) and a gyro sensor (not shown). The acceleration sensor (not shown) senses the movement and impact of the mobile terminal. For example, when the position of the mobile terminal is moved by the user, the movement speed of the mobile terminal is changed, and the acceleration sensor (not shown) rotates based on a specific reference point And so on.

The gyro sensor (not shown) senses the inclination of the body of the mobile terminal. For example, the gyro sensor (not shown) can sense the rotation of the gyro sensor based on a reference point located inside or outside the main body of the mobile terminal.

Referring to (c) of FIG. 5A, the user can move the position of the mobile terminal body in the call mode. For example, a mobile terminal located close to a user's face may be moved away from the face to detect a voice signal output to the first sound output module 153a.

The sensing unit 140 senses a relative position between the mobile terminal and the user. For example, the proximity sensor (not shown) recognizes a change in the relative position of the mobile terminal when an external object (user's face) located close to the main body is not detected.

Also, the movement of the mobile terminal body can be detected by the acceleration sensor (not shown) and the gyro sensor (not shown).

The user can recognize the time information outputted from the display unit 151 mounted on one side of the main body by moving the main body of the mobile terminal. That is, the user can receive the time information from the display unit 151 or move the main body of the mobile terminal such that the face and the display unit 151 are separated from each other when the user desires to apply the touch input to the display unit 151 have.

The control unit 180 controls the display unit 151 to output a text corresponding to the voice signal when a change in the relative position is detected (S604). The control unit 180 converts the voice signal received from the external terminal through the wireless communication unit 110 into text. The control unit 180 may control the display unit 151 to output the text 610 on the call screen 510. [

For example, the control unit 180 may control the display unit 151 to output the text 610 so as to overlap with the representative image included in the call screen 510. In this case, the controller 180 may control the display unit 151 to adjust the transparency of at least one area of the call screen 510.

However, the method in which the text 610 is overlapped with the call screen 510 is not limited thereto. For example, the control unit 180 controls the display unit 151 to display a pop-up window that is displayed to cover at least a part of the call screen 510 and includes the text.

The control unit 180 may control the display unit 151 to convert the voice signal into text in real time and to output the text in the order of the received time. The text 610 may include various languages, numbers, and special characters that are predicted according to the user's intonation provided by the mobile terminal.

Referring to FIG. 5 (d), the text 610 includes at least one sentence in which the voice of the other party received from the external terminal is switched. For example, I went to the cafe in Gangnam yesterday. 0223451234 ".

The user can recognize the text 610 output to the display unit 151. [ The control unit 180 may control the sound output module 153 to output the voice signal. The control unit 180 may control the sound output module 153 of the display unit 151 to output the text and the voice signal at substantially the same time or at predetermined time intervals.

Although not shown, the controller 180 controls the display unit 151 to adjust the volume of the voice signal output from the sound output module 153 while the text 610 is output .

Accordingly, the user can receive the voice signal of the other party received from the external terminal in text form when the mobile terminal is located far from the face of the user and the voice signal can not be delivered to the user's ear.

In addition, during the communication mode, the user can receive desired screen information output from the display unit 151 together with a text corresponding to a voice signal of the other party, and controls the mobile terminal by applying a touch input to the display unit 151 .

The control unit 180 may control the display unit 151 to convert the voice of the user input into the microphone 122 into text and output the text together with the text 610 corresponding to the voice signal of the other party have.

5B through 5E are conceptual diagrams for explaining the control method of FIG. 4 according to other embodiments.

Referring to FIG. 5B, the controller 180 activates the speakerphone mode when the face of the user adjacent to the main body of the mobile terminal is not detected in the call mode. Also, the controller 180 controls the display unit 151 to output a text corresponding to a voice signal received from the external terminal.

That is, when the user places the mobile terminal unit away from the face during a call with the external terminal, the user can switch the speakerphone mode to receive the voice signal of the other party and provide the voice signal of the other party as text.

The case where the communication mode is activated while another application is running will be described with reference to FIG. 5C. 5C is a diagram showing an execution screen of the application activated before the call signal is received.

When the call signal is received, the execution screen 570 of the application is switched to the screen information 500 informing reception of the call. The control unit 180 activates a call mode for connecting the call based on a control command applied to the mobile terminal. The user may place the mobile terminal body close to the user's face to receive the voice signal output by the first sound output module 153a.

The sensing unit senses whether there is an object in proximity to the mobile terminal in the call mode. For example, if the proximity sensor (not shown) is adjacent to the user's face and moves away from the user's face, the proximity sensor (not shown) detects that the proximity sensor Detection.

Referring to FIGS. 5B and 5C, when the controller 180 detects that the mobile terminal is distant from the user's face by the sensing unit, the controller 180 displays the screen information before the call signal is received, And controls the display unit 151 to output the execution screen 570 of the application.

The execution screen 570 is displayed to cover at least a part of the call screen 510 and may be output together with the text. For example, the control unit 180 may control the display unit 151 to display a popup window overlapping at least a part of the call screen 510 and to display the execution screen 570 in the popup window have.

When the main body of the mobile terminal is supported by the ground or the like in the call mode, the controller 180 outputs the execution screen 570 of the application or displays the icon of the application on the display unit 151 Can be controlled.

Referring to FIG. 5E, a control method of the communication mode based on the state of the mobile terminal supported on the ground will be described.

Referring to FIGS. 5A and 5B, when the mobile terminal body is supported by the ground in a communication mode disposed adjacent to the face of the user, the sensing unit senses this.

FIG. 5 (b) shows a case in which the rear surface is supported by the ground so that the display unit 151 is exposed to the outside. The control unit 180 controls the display unit 151 to switch the voice signal to text and output the text if it is detected that the body of the mobile terminal is supported by the ground or the like and is in a stable state.

For example, a proximity sensor (not shown) and an illuminance sensor formed adjacent to the display unit 151 detect whether the display unit 151 is blocked by the ground. The second sound output module 153b formed on the surface opposite to the display unit 151 may be determined to be exposed to the outside if the display unit 151 is detected to be covered by the ground.

The controller 180 controls the first sound output module 153a to output the sound signal in a state that the display unit 151 is covered by the ground or the like and the second sound output module 153b is exposed to the outside, ).

In addition, the controller 180 may switch the call mode to the speakerphone mode based on the touch input applied to the graphic image for switching the mode of the mobile terminal to the speakerphone mode.

Based on the touch input, the controller 180 switches the call mode to the speakerphone mode and controls the second sound output module 153b to output the voice signal.

A control method of storing the text will be described with reference to FIG. 7C.

Referring to FIGS. 7A and 7B, the controller 180 controls the display unit 151 to terminate the call mode based on a touch input applied to the call end graphic image.

When the call mode is terminated, the display unit 151 displays the call end screen 520 (see FIG. 7C) and displays the call record screen 530 The controller 151 controls the display unit 151 to output the image data.

For example, the call log screen 530 includes information about at least one call log sorted by a predetermined criterion. For example, the display unit 151 may include information on an external terminal having a recorded call, a call connection state, a call connection time, and graphic images for sending a message or calling a call.

Referring to FIGS. 7B and 7C, on the basis of the touch input to the information on one of the call recording screens 530, the control unit 180 determines whether the voice of the other party or the user And controls the display unit 151 to output the converted text.

8 is a conceptual diagram illustrating a control method of executing an associated application based on a change in position sensed by the sensing unit.

When the communication mode is activated, the controller 180 detects a positional change of the mobile terminal by the sensing unit. Here, the positional change may include a relative position between the user and the mobile terminal (particularly, the display unit 151). For example, the relative positional shift of the mobile terminal, which is positioned adjacent to the face of the user, to move away from the user's face to receive the voice signal output to the first sound output module 153a, Can be detected.

The control unit 180 may control the display unit 151 to output at least one icon according to the change of the relative position sensed by the sensing unit. The display unit 151 may output the icons on the call screen 510.

The control unit 180 may control the display unit 151 to output an icon of an application preset to be output in the call mode on the call screen 510. [ The application can be set by the user.

Alternatively, the control unit 180 stores the application that was activated in the call mode by the user, and controls the display unit 151 to output the icons according to the order of activation.

Alternatively, the control unit 180 can recognize the contents of the voice received at the mobile terminal by the user and the other party, and select a predetermined number of applications related to the text corresponding to the voice signal.

8A and 8B, the controller 180 may execute the application based on a touch input applied to an icon displayed on the call screen 510. FIG. The control unit 180 controls the display unit 151 to output the execution screen of the application on the call screen 510 in the call mode.

For example, the control unit 180 executes a memo application that activates an input window for inputting content based on a touch input applied to the memo icon. The control unit 180 controls the display unit 151 to output a text corresponding to the voice signal received in the call mode on the execution screen 730 of the memo application. That is, the control unit 180 may control the display unit 151 to record the text in the memo application running in the call mode.

Also, the controller 180 may control the memory 160 to store the text in a storage space allocated to the memo application, based on a control command applied to the execution screen 730 of the memo application.

8 (a) and 8 (c), the control unit 180 outputs the execution screen 730 of the application, inputs content by touch input on the execution screen 730, The display unit 151 can be controlled so as to output the virtual keyboard 731 to be displayed. The control unit 180 controls the display unit 151 to output the content to the execution screen based on the control command applied to the virtual keyboard 731. [

The control unit 180 may control the display unit 151 to output the text on the call screen 510 so as to overlap with the execution screen 730. In addition, the controller 180 may control the display unit 151 to adjust the transparency of the execution screen 730 and the call screen 510 so as to overlap each other. That is, the user can perform a communication function with the other party in the communication mode and can easily control another application.

Accordingly, the user can be provided with an executable application by the movement of the mobile terminal, can input the text of the voice signal received in real time to the application, and can execute the application execution screen and the text irrelevant to the application substantially simultaneously Can be provided.

In the above description, the screen information on the display unit 151 is controlled according to the relative position of the mobile terminal while the user is holding the terminal main body. Hereinafter, a method of controlling screen information by sensing a user's hand touching the mobile terminal will be described.

9A to 9D illustrate a control method based on the detection of the position of the hand of the user supporting the mobile terminal in the call mode.

9A, a control method for switching the call mode to the speakerphone mode when the contact of the hand is canceled from the mobile terminal will be described. Referring to FIGS. 9A and 9B, in the communication mode, the sensing unit 140 senses that the main body of the mobile terminal is detached from a hand of a user supporting the main body of the mobile terminal.

The controller 180 controls the first sound output module 153a to output a voice signal of the other party in the call mode. In addition, the controller 180 controls the display unit 151 to display a call screen in the call mode, and may switch the display unit 151 to an inactive state after a predetermined period of time.

Here, the user's hand supporting the main body can be substantially in contact with the outside of the mobile terminal, and when the mobile terminal is disposed on the ground, the user's hand and the main body of the mobile terminal can be separated.

The sensing unit 140 may include a touch panel constituting the display unit 151. The touch panel may sense a change in a magnetic field caused by a user's hand positioned close to the display unit 151 in order to support the user's touch input on the touch panel as well as the mobile terminal. Accordingly, the control unit 180 can recognize the grip of the hand by the hand of the user adjacent to the display unit 151 sensed by the sensing unit 140 implemented by the touch panel.

The control unit 180 may detect that the mobile terminal is separated from the hand based on not only the sensing of the touch panel but also the acceleration sensor (not shown) and the gyro sensor (not shown) included in the sensing unit 140 have.

The control unit 180 controls the display unit 151 to change the call mode to the speakerphone mode when the user is disconnected from the mobile terminal. Here, the speakerphone mode is a mode in which the voice signal received from the external terminal is controlled to be output by the second sound output module 153b. In this case, the controller 180 may limit the audio signal output to the first sound output module 153a.

The controller 180 may control the caller mode to be switched to the speakerphone mode if the degree of movement of the mobile terminal is detected by the sensing unit 140 to be less than a preset range. That is, when the physical movement of the mobile terminal is detected as a stable state, the controller 180 may activate the speakerphone mode.

9 (c), the controller 180 converts the voice signal received from the external terminal and output through the second sound output module 153b into text, and outputs the text And controls the display unit 151.

The controller 180 controls the display unit 151 to output the call screen 510 when the speakerphone mode is switched to the speakerphone mode. The control unit 180 controls the display unit 151 to output the text 610 on the call screen 510.

The control unit 180 controls the display unit 151 to indicate that the graphic image output from the call screen 510 is switched to the speakerphone mode so as to receive a control command to switch to the speakerphone. For example, the control unit 180 controls the display unit 151 to output the graphics image in a modified form.

 The method of outputting the text 610 on the display unit 151 in the speakerphone mode is substantially the same as that of the embodiment of FIGS. 6A to 6C, and a description thereof will be omitted.

The control unit 180 may control the display unit 151 to output the text 610 corresponding to the voice signal output to the second sound output module 153b in real time. The control unit 180 may control the display unit 151 to convert the voice of the user input into the microphone 122 into a text and output the text.

9A, the control unit 180 controls the display unit 151 to display the text 610 on the basis of the touch input applied to one area on the display unit 151, Can be activated. The control unit 180 outputs the execution screen 720 of the application on the display unit 151. The display unit 151 displays the application execution screen 720 together with the execution screen 720, Mode can be displayed.

Accordingly, when the distance between the mobile terminal and the user is increased in the call mode, the speakerphone mode is automatically activated, so that the user can smoothly communicate with the external terminal.

In addition, since the voice signal can be provided as text when it is desired to receive the time information on the display unit 151 together with the positional change of the mobile terminal, even when the voice signal is not clear in the speakerphone mode, Can be performed smoothly.

Further, since the user can operate the mobile terminal for switching to the speakerphone, it is possible to switch to the speakerphone mode more conveniently.

Although not shown in the drawing, when the mobile terminal is contacted with the user's hand (supported by the user's hand) in the speakerphone mode and is detected as being adjacent to the mobile terminal and the user, Speakerphone mode can be disabled.

That is, the controller 180 may control the speakerphone mode based on the distance between the mobile terminal and the user and whether or not the user is in contact with the mobile terminal.

9B is a diagram for explaining a control method of cutting off the sound output in the speakerphone mode.

The control unit 180 controls the sensing unit to sense an object close to the mobile terminal when the main body of the mobile terminal is supported by the ground or the like and the speakerphone mode is activated.

For example, the controller 180 controls the sensing unit to detect a gesture of a hand positioned adjacent to the mobile terminal. For example, the illuminance sensor mounted on the mobile terminal senses a variation in illuminance caused by the movement of the hand or a proximity sensor (not shown) to detect movement of the user's hand .

For example, the gesture may correspond to the palm of a user moving closer on the mobile terminal.

The control unit 180 controls the second sound output module 153b to limit the output of the voice signal in the speakerphone mode when the gesture of the hand set by the sensing unit is sensed.

Meanwhile, the control unit 180 may control the display unit 151 to output text corresponding to the voice signal in the speakerphone mode, substantially irrespective of the control of the second sound output module 153b .

That is, the user can restrict the output of the voice signal based on the gesture of the user in the state of being switched to the speakerphone mode, and the voice signal output by the second sound output module 153b is limited to the text And can be continuously provided.

Accordingly, the user can more easily control the mode change and the limitation of the sound output, so that the user can communicate with the external terminal in a desired manner.

A control method of transmitting time data on the display unit 151 generated in the speakerphone mode to the external terminal will be described with reference to FIG.

Referring to (a) of FIG. 9, the mobile terminal transmits and receives a radio signal to and from the second terminal, and the first terminal is in a state in which the call mode is activated. In the figure, P is the user of the first terminal and Q is the user of the second terminal. The mobile terminal is a call mode and outputs the voice signal received from the second terminal to the user P via the first sound output module 153a.

Referring to FIG. 9 (b), the controller 180 detects a positional change of the mobile terminal unit based on the sensing unit. That is, the control unit 180 activates the speakerphone mode when the mobile unit is separated from the user P by the sensing unit and is sensed as being stable. In addition, the controller 180 controls the display unit 151 to output the predetermined screen information.

For example, the control unit 180 controls the display unit 151 to output the execution screen 720 of the map application based on the touch input applied to the display unit 151. Although not shown in the figure, the display unit 151 may output text corresponding to the voice signal together with the execution screen 720.

The control unit 180 may input additional information based on a touch input on the display unit 151 that outputs the execution screen 270. [ For example, a specific position may be specified on the execution screen 270 including the map, or a shape may be inputted so as to overlap with the execution screen 270.

The control unit 180 may control the wireless communication unit to transmit screen information including the execution screen 270 and the additional information input thereto to the second terminal 100 '. The controller 180 may transmit the screen information in real time reflecting the input additional information, but the present invention is not limited thereto. For example, the control unit 180 may transmit the screen information according to a control command applied to the display unit 151 or may control the wireless communication unit to transmit updated screen information at a predetermined time interval .

Referring to FIGS. 9 (b) and 9 (c), the second terminal 100 'receives screen information from the first terminal 100 in the call mode. However, in the communication mode, the controller 180 of the second terminal 100 'controls the display unit 151 to limit the output of the screen information.

The control unit 180 of the second terminal 100 'switches the call mode to the speakerphone mode when it is detected that the main body of the second terminal 100' is in a stable state. In addition, the controller 180 controls the display unit 151 of the second terminal 100 'to output the screen information.

That is, the control unit 180 controls the display unit 151 to output the visual information received in the call mode when the speakerphone mode is switched.

Referring to FIG. 9D, a control method for switching the text applied to the display unit 151 to a voice signal in the speakerphone mode and transmitting the voice signal will be described.

FIG. 9D shows a state in which the mobile terminal is in a stable state and a speakerphone mode is activated. 9D, the display unit 151 outputs the execution screen 720 of the specific application and the text 610 corresponding to the voice signal received from the external terminal.

The display unit 151 controls the transparency of the call screen 510, the execution screen 720 and the text 610 or the execution screen 720 and the text 610 are displayed on the call screen 510, Up window (not shown) that is output on the display device.

The control unit 180 may control the display unit 151 to output a virtual keyboard 650 that receives a control command for inputting information based on a touch input applied on the display unit 151 . The virtual keyboard 650 may be displayed so as to overlap with the execution screen 720 and the call screen 510. [

The control unit 180 controls the display unit 151 to input information based on the touch input applied to the virtual keyboard 650. The information may be implemented in the form of text to be transmitted to the external terminal. The display unit 151 controls the display unit 151 to output the information 651 in an area adjacent to the text 610 corresponding to the voice signal of the external terminal based on the touch input.

The control unit 180 controls the wireless communication unit to convert the information 651 output on the display unit 151 into a voice signal and transmit the voice signal to the external terminal. That is, the external terminal can receive information inputted as text by a user as a sound signal.

According to the present embodiment, in the speakerphone mode, the user can input a voice signal through the microphone 122 and make a call with an external terminal according to information input on the display unit 151. [ In this case, the controller 180 may block the output of the voice signal received from the external terminal to the second sound output module 153b by the gesture described with reference to FIG. 9B.

That is, the mobile terminal can perform a call function with an external terminal using at least one of the display unit 151, the speaker, and the microphone 122 in the speakerphone mode.

10A and 10B are conceptual diagrams for explaining a control method of controlling a call mode based on a positional change of a mobile terminal body by a user.

10A shows a state in which a call is received from an external terminal when the mobile terminal body is supported on a ground or the like and a user's hand is not positioned close to the user terminal.

Referring to FIG. 10 (b), when the mobile terminal body is supported by the user's hand, the sensing unit senses the user's hand. Particularly, the touch panel constituting the display unit 151 senses that the user's hand is positioned close to the mobile terminal even when the user's hand touches or does not touch the touch panel.

For example, when the user supports the mobile terminal using only the side surface and the rear surface of the mobile terminal, the touch panel senses the change of the magnetic field by the user's hand adjacent to the side of the display portion 151, The position of the hand supporting the terminal can be roughly detected.

In addition, the sensing unit may sense movement of the mobile terminal body. For example, the acceleration sensor and the gyro sensor detect movement of the main body while moving from the ground to the user's hand.

Referring to (c) of FIG. 10, when the main body of the mobile terminal moves close to the face of the user, the controller 180 activates the call mode based on the movement of the terminal detected by the sensing unit. That is, the user can switch the received call to the connected state without any separate control command applied to the display unit 151 and the signal input unit.

Referring to (c) of FIG. 10, the controller 180 may control the display unit 151 to switch the mobile terminal to the call mode and output the call screen 510.

When the hand of the user located close to the mobile terminal is detected, the controller 180 switches to the call mode, or when a hand near the mobile terminal is detected and movement of the main body is detected by the detection unit, You can switch. This can be set by the user.

Referring to FIG. 10B, a method of controlling differently based on the speed of the positional change sensed by the sensing unit will be described.

10 (a) shows a state in which a call is received in a state where the mobile terminal body is supported by a ground or the like. The controller 180 controls the second sound output module 153b to output a notification sound having a predetermined volume in order to notify the call received from the external terminal. For example, it is assumed that the predetermined volume is 10.

Referring to FIGS. 10B and 10C, the sensing unit senses a hand of a user who is close to the mobile terminal and senses a positional variation of the mobile terminal body moved by the user's hand. In addition, the sensing unit senses a speed at which the mobile terminal body is moved. The control unit 180 may control the mobile terminal differently according to the speeds changed by the sensing unit.

For example, referring to (b) of FIG. 10, the controller 180 may activate the call mode when the moving speed of the mobile terminal is the first speed v1. If the moving speed is greater than a predetermined reference speed, the controller 180 may define the first speed v1.

Although not shown in the drawing, when the movement of the main body is detected at a speed corresponding to the first speed v1 in a state of being supported by a user's hand rather than being supported on the main body of the mobile terminal The call mode can be activated.

That is, when the mobile terminal moves at a predetermined speed or higher, the control unit 180 can switch a call mode to a call mode by connecting a call being received. That is, the user can move the mobile terminal faster than a predetermined speed to activate the communication mode. In this case, the controller 180 may detect whether the user's face and the body of the mobile terminal are close to each other by using a proximity sensor (not shown) proximity sensor (not shown), and control the activation of the call mode .

10B, when the moving speed of the mobile terminal is the second speed v2, the controller 180 controls the second sound output module 153b It is possible to control the volume of the output notification sound to be reduced. The second speed v2 may be defined to be slower than the reference speed.

The controller 180 may control the second sound output module 153b to gradually decrease the volume of the alarm sound. The control unit 180 may control the volume of the notification sound to be reduced by a predetermined volume, and the predetermined volume may correspond to the smallest volume.

However, the present invention is not limited to this, and the controller 180 may control the second sound output module 153b to gradually decrease the volume until the sound volume is muted. In addition, when the movement is detected, it can be controlled to a mute state.

Referring to FIG. 10 (d), the controller 180 controls the second sound output module 153b to continuously output the alarm sound in a reduced volume. For example, when the body of the mobile terminal is supported on the ground by the sensing unit, the control unit 180 controls the second sound output module 153b to output a notification sound at the reduced volume, Can be controlled.

As a result, the user can control the notification sound output to the outside more quickly.

FIG. 11 is a flowchart for explaining a method of controlling the display unit 151 according to the rotation of the mobile terminal body. FIG. 12A is a conceptual diagram for explaining the control method of FIG. 11 according to an embodiment.

11 and 12A, a control method of detecting the rotation speed and switching the screen information output to the display unit 151 will be described.

Referring to FIG. 12A, the display unit 151 outputs screen information 550. For example, the screen information 550 corresponds to an execution screen of a message application, and the execution screen may include a virtual keyboard for inputting characters. The display unit 151 is output in a first direction which is the longitudinal direction of the mobile terminal body.

The control unit 180 controls the sensing unit to sense the movement of the mobile terminal body (S612). The mobile terminal determines whether the main body of the mobile terminal is located on the ground (S613). That is, the controller 180 determines whether the main body is in a stable state on the ground.

The control unit 180 controls the two-dimensional rotation to be sensed when the main body of the terminal moves on the ground (S614a). The control unit 180 controls the three-dimensional rotation to be sensed when the main body of the terminal is supported by the user's hand, (S614b). In the case of the two-dimensional rotation, the controller 180 measures an orientation variation of the main body using an acceleration sensor, and measures a direction variation using a gyro sensor when the three-dimensional rotation is performed. However, the present invention is not limited thereto.

The controller 180 senses two-dimensional rotation and three-dimensional rotation and determines whether the direction of the main body of the terminal has changed (S615). The control unit 180 determines whether there is a directional change to a predetermined degree or more. The preset degree can be set by the user or automatically set based on the movement of the mobile terminal that is usually measured and stored.

The controller 180 senses the rotation speed when the direction variation exists. For example, the angular velocity of the mobile terminal body is measured (S616). The controller 180 compares the angular velocity with a preset reference angular velocity (S617).

The control unit 180 may control the display unit 151 in different ways by comparing the angular velocity and the reference angular velocity. Referring to FIGS. 12A and 12B, when the main body of the mobile terminal rotates at the first speed v1, the controller 180 outputs the screen information 550, which is output in the first direction, And output in a second direction intersecting with the first direction. In the present embodiment, it is assumed that the main body of the mobile terminal is rotated substantially vertically for convenience of explanation.

The modified screen information 550 'output in the second direction is substantially the same as the content included in the screen information 550, but the shape of the content included in the screen information may be changed. Also, the direction of the virtual keyboard is switched to the second direction and outputted. If the rotational speed of the body is faster than a predetermined reference speed, the controller 180 assumes that the rotational speed of the main body has rotated at the first speed v1.

12A and 12C, when the rotation speed of the main body is measured at a second speed v2 that is slower than the reference speed, the control unit 180 changes the output direction of the screen information . That is, in a state where the mobile terminal body is rotated, the controller 180 controls the display unit 151 to continuously output the screen information output in the first direction.

That is, the controller 180 controls the display unit 151 to output the screen information in a direction crossing the screen information when the user rotates faster than the reference speed (i.e., when the angular velocity is faster). In addition, the controller 180 controls the display unit 151 to output the screen information without changing the display direction of the screen information when it is rotated slower than the reference speed (i.e., when the angular velocity is slow).

Accordingly, the user can control the output of the screen information without changing the output of the screen information by the rotation of the mobile terminal or without a control command for restricting the change.

Referring to FIG. 12B, the control unit 180 controls the output direction of the screen information by the vibration applied to the mobile terminal unit.

The controller 180 controls the display unit 151 to detect a physical force applied to the main body of the mobile terminal in a state in which screen information is output in the second direction.

The control unit 180 may change the output direction of the screen information by the vibration of the mobile terminal body detected by the sensing unit. As shown in the figure, the controller 180 controls the display unit 151 to switch the changed screen information 550 'to the screen information 550.

For example, when the vibration of the main body is detected, the controller 180 controls the display unit 151 to output the screen information. The control unit 180 may control the display unit 151 to output the screen information in a predetermined direction when the vibration is detected.

Alternatively, when the vibration is detected, the display unit 151 may be controlled to output the screen information alternately in the first direction or the second direction.

13A to 13E, a method of controlling a mobile terminal by sensing a hand supporting the mobile terminal body according to various embodiments will be described.

13A, a control method for executing a predetermined function based on the position of the hand contacting the main body and the movement of the main body will be described.

13A shows a display unit 151 on which a home screen image is output. The touch panel of the display unit 151 is positioned close to the display unit 151 to sense a user's hand supporting the main body, and the sensing unit senses the degree of tilting of the main body of the mobile terminal.

For example, the sensing unit may sense that the longitudinal direction of the mobile terminal body intersects with the gravity direction (i.e., when the mobile terminal body is tilted sideways with respect to the ground). In addition, the touch panel may sense that the user's hand touches the predetermined position of the mobile terminal body. For example, four fingers of both hands of a user may support four corners or four sides of the mobile terminal body.

The control unit 180 executes a camera application for acquiring an image using the camera module based on the state of the main body and the finger position of the user based on the sensing unit and the touch panel.

The state of the mobile terminal main body and the position of the user's hand for executing the predetermined function can be defined by the user's setting. It is preferable that the state of the user and the position of the hand to be held when the specific function is executed are set as conditions for executing the specific function.

13 (c), when the position of the mobile terminal is changed in a state where the user's hand is located in the main body of the mobile terminal, the control unit 180 detects the position of the mobile terminal, The display unit 151 can be controlled to output the image data.

For example, the control unit 180 may control the display unit 151 to execute an application related to the camera application, such as a gallery application, and to output an execution screen thereof.

For example, the control unit 180 may execute the another application when the mobile terminal moves due to a user's hand touching the main body of the mobile terminal, or when the slope of the mobile terminal changes.

Accordingly, the user can execute the control command without executing the control command to execute the specific application.

Referring to FIG. 13B, a control method of sensing a position of a user's hand supporting the mobile terminal body and receiving user input in a different manner will be described.

13B, the controller 180 senses a user's hand supporting the side surface of the mobile terminal body with both hands by the touch panel and applies a touch input of the display unit 151 to the text And outputs a virtual keyboard 561 for inputting the virtual keyboard 561. [

In addition, the controller 180 detects the degree of tilting of the mobile terminal body through the sensing unit, and controls the display unit 151 to output different types of virtual keyboards according to the position of the mobile terminal body .

Referring to FIG. 13B, when the main body of the mobile terminal is supported by one hand by the touch panel, the controller 180 activates the microphone 122 to receive a user's voice signal, The microphone 122 can be controlled to receive a control command based on a voice signal.

That is, when the control unit 180 receives a control command or information from the user, the control unit 180 may activate different input methods according to a user's hand touching a specific area of the mobile terminal body to support the mobile terminal.

Referring to FIG. 13C, a control method for detecting the hand of the user supporting the mobile terminal body and providing specific information will be described.

The control unit 180 detects a hand of a user who is close to the mobile terminal and provides information on an event when a specific event occurs in the mobile terminal and the display unit 151 is in an inactive state.

For example, a case where the display unit 151 is switched to the inactive state after the incoming call is not connected and the out-of-office call is recorded will be described. The controller 180 switches the display unit 151 to the active state when the user's hand touches the main body of the mobile terminal to support the mobile terminal, The control unit 151 can be controlled.

On the other hand, when there is no event occurring in the mobile terminal, the controller 180 does not switch the display unit 151 to the active state.

 The event is not limited to the notification of the missed call, but may include various information received through the wireless communication unit, an alarm set by the user, and the like.

Accordingly, the user can be informed about the occurrence of the event when the user performs an action such as lifting or holding the mobile terminal without activating the display unit 151 and confirming whether or not the event is generated.

Referring to FIG. 13D, a control method of the locking function will be described in the case where the contact of the user's hand continues to the mobile terminal body.

Referring to FIGS. 13 (a) to 13 (d), when the controller 180 activates the disabled display unit 151 while the main body of the mobile terminal is supported by the user's hand, And controls the display unit 151 to output a pattern input screen 571 for termination.

However, screen information for password input, fingerprint recognition, user face recognition, etc., as well as the pattern input screen 571 may be output for unlocking.

If the locking function is canceled in a state where a user's hand is in contact with one region of the mobile terminal body, the display unit 151 outputs a home screen page 540. Also, after a predetermined time, the display unit 151 is switched to the inactive state. However, the present invention is not limited to the home screen page 540, and an execution screen of a recently activated application, preset screen information, or the like may be output.

The control unit 180 activates the display unit 151 based on a control command applied to the mobile terminal when one area of the mobile terminal unit is continuously in contact with the user's hand.

Also, the controller 180 controls the display unit 151 to output the home screen page 540 again. That is, the pattern input screen 571 for canceling the lock function is not output even when the display unit 151 is switched from the inactive state to the active state.

That is, when the mobile terminal is continuously supported by the hand of the user, the control unit 180 transmits a pattern for canceling the lock function when the lock function is canceled according to a touch input applied to the pattern input screen 571 Limit the re-output of the input screen.

Accordingly, when the user is continuously holding the mobile terminal, the user does not have to input the lock-unlock control command (password or the like) repeatedly to activate the display unit 151 again

A control method of activating the function while the hand is in contact with the mobile terminal body will be described with reference to FIG.

13 (a) shows a state in which sound is output through the second sound output module 153b, and the display unit 151 is in a deactivated state.

Referring to FIG. 13 (b), when the user touches the main body of the mobile terminal while the display unit 151 is in the inactive state, the control unit 180 outputs an execution screen of the application related to the sound And controls the display unit 151.

For example, when the control unit 180 detects that the user's hand is positioned close to the display unit 151, the control unit 180 displays an execution screen 581 of the application being executed to output the sound (for example, A media application such as a playback application, a moving image playback application, etc.).

The control unit 180 may control the application by touch input applied to the execution screen 581 in a state in which a hand adjacent to the mobile terminal body is detected. For example, the control unit 180 may control the display unit 151 to output the additional information 582 by a touch input applied to the execution screen 581. For example, the control unit 180 may control the display unit 151 to display a song lyrics or the like output from the second sound output module 153b.

Referring to FIG. 13D, when the hand of the user is deformed so that the hand adjacent to the touch panel is not sensed, the controller 180 controls the operation of the execution screen 581 And controls the display unit 151 to limit the output.

For example, the control unit 180 controls the display unit 151 to switch the execution screen 581 to the home screen screen 540.

However, the present invention is not limited thereto. For example, it is possible to output the execution screen for a preset time, to restrict only the touch input, or to control the display unit 151 to be in an inactive state.

Accordingly, the user can use the hand touching the mobile terminal to receive the screen information of the currently executed application and to control the application.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
