Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect 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, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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.

Thus, when 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. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected 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 change of light, and position information of the object to be sensed can be obtained through the calculation.

However, the present invention is not limited to this, and the sound may be configured to be emitted along an assembly gap (for example, a gap between the window 151a and the front case 101) between the structures. In this case, the appearance of the mobile terminal 100 can be made more simple because the hole formed independently for the apparent acoustic output is hidden or hidden.

The optical output unit 154 is configured to output light for notifying the occurrence of an event. Examples of the event include a message reception, a call signal reception, a missed call, an alarm, a schedule notification, an email reception, and reception of information through an application. The control unit 180 may control the light output unit 154 to start or stop the output of light when the event confirmation of the user is detected.

The first camera 121a processes an image frame of a still image or a moving image obtained by the image sensor in the photographing mode or the video communication mode. The processed image frame can be displayed on the display unit 151 and can be stored in the memory 170. [

The first and second operation units 123a and 123b may be collectively referred to as a manipulating portion as an example of a user input unit 123 operated to receive a command for controlling the operation of the mobile terminal 100 have. The first and second operation units 123a and 123b can be employed in any manner as long as the user is in a tactile manner such as touch, push, scroll, or the like.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2 is a flowchart illustrating a control method of the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 2, first, the control unit 180 turns the display unit 151 into an inactive state (S210). In the present invention, the inactive state means a state in which no information is displayed on the display unit 151. [ The control unit 180 can turn the display unit 151 into an inactive state by turning off the illumination of the display unit 151 (e.g., LCD, etc.). Specifically, when the control unit 180 switches the display unit 151 to the inactive state, execution screen information of an application program driven by the mobile terminal 100, UI (User Interface), GUI Graphic User Interface) information of the mobile terminal 100 can not be visually confirmed from the outside. Even when the display unit 151 is switched to the inactive state, processing of at least one information or driving of a predetermined application program can be executed internally of the mobile terminal 100, It is a matter of course that it is possible.

The case where the control unit 180 switches the display unit 151 to the inactive state may vary. For example, the control unit 180 may switch the display unit 151 to the inactive state if no event occurs over a predetermined time limit. Here, the event may be various, such as receiving a call, receiving a message, receiving a touch to the display unit 151 in an activated state, or the like. Alternatively, the control unit 180 may switch the display unit 151 to the inactive state when receiving a user input for pushing the power button provided on the main body of the mobile terminal 100. [ At this time, it is needless to say that the controller 180 can switch the display unit 151 back to the active state upon receiving a user input that pushes the power button again. As another example, the control unit 180 may switch the display unit 151 to the inactive state based on the voice input.

Next, the control unit 180 recognizes the first touch point and the second touch point of the multi-touch input through the display unit 151 (S220). In the present invention, the multi-touch is a touch that is simultaneously input at a plurality of points that can be distinguished from each other through the display unit 151, and is a concept as compared with a single touch that is input at one point at a time. The means by which the multi-touch can be input is typically, but not exclusively, a user's hand. For example, the Mulert Teach may be input through a stylus pen or the like. Further, the multi-touch may be input from two or more mutually combined means. For example, the first touch point for the display unit 151 may be a point at which the user's finger touches the touch point, and the second touch point may be a point at which the stylus pen touches the touch point.

The control unit 180 may calculate the coordinates corresponding to the first touch point and the coordinates corresponding to the second touch point. For example, the x-coordinate is the width direction coordinate with respect to the center of the display unit 151, and the y-coordinate is the coordinate of the display unit 151, May be a longitudinal direction coordinate with respect to the center of the second lens.

At this time, if the multi-touch does not correspond to the predetermined pattern, the control unit 180 may not perform the control operation of the predetermined function based on the multi-touch. For example, when the total number of touch points included in the multi-touch is equal to or greater than a predetermined number, or when the total area of the touch points is out of a predetermined range, the controller 180 may not perform any operation. Alternatively, the control unit 180 may not perform any operation even when the multi-touch is released after a predetermined time (e.g., one second) is maintained. This is to prevent a situation where a user does not intend to control a predetermined function through multi-touch but malfunctions. The control unit 180 can generate different visual effects, tactile or auditory effects when the multi-touch corresponds to any one of the predetermined patterns and when the multi-touch corresponds to any of the predetermined patterns. For example, when the multi-touch does not correspond to any of the predetermined patterns, the control unit 180 outputs the red light through the light output unit 154. When the light output unit 154 corresponds to the predetermined pattern, The green light can be outputted through the light source.

Next, the controller 180 controls at least one of a plurality of functions executable by the mobile terminal 100 based on the drag direction and the drag distance of the first touch point and the second touch point (S230). Here, a function that can be executed by the mobile terminal 100 may be a function related to an application program installed in the mobile terminal 100. Alternatively, the function executable in the mobile terminal 100 may be a function of changing the state preset in the mobile terminal 100 to another state.

Specifically, the function corresponding to the drag direction of the first touch point and the second touch point may be stored in the memory 170 in advance. For example, when the drag direction of the first touch point and the second touch point are the same in the first direction, the control unit 180 can select the function to control the first function based on the information stored in the memory 170 . In another example, when the drag direction of the first touch point is the first direction and the drag direction of the second touch point is the second direction, the control unit 180 determines whether the drag direction of the first touch point is different from the first function based on the information stored in the memory 170 The function to control the second function can be selected.

In addition, the control amount corresponding to the drag distance of the first touch point and the second touch point may be stored in advance in the memory 170 according to the function. For example, when the first function among various functions executable in the mobile terminal 100 is selected and the total drag distance of the first touch point and the second touch point is increased by the first distance, 1 function can be increased by the first value. As another example, in a state where the second function among the various functions executable in the mobile terminal 100 is selected, the control unit 180, whenever the total drag distance of the first touch point and the second touch point increases by the second distance The control amount of the second function can be reduced by the second value.

On the other hand, the control unit 180 can set the function-adjustable range based on the information about the surrounding environment. Specifically, the control unit 180 may control the predetermined function based on the measured values of the surrounding environment provided from the sensing unit 140 or the input unit 120 according to the drag distance of the first touch point and the second touch point At least one of the upper limit value and the lower limit value can be set. The control unit 180 may receive the illuminance measurement value from the illuminance sensor 142 of the sensing unit 140 or may receive the noise measurement value from the microphone 122 of the input unit 120. The upper limit value or the lower limit value for each illumination measurement value for at least one function executable in the mobile terminal 100 may be stored in the memory 170 in advance and the upper limit value or the lower limit value for each noise measurement value for other functions may be stored in advance.

3 is a conceptual diagram for explaining an operation of increasing the brightness of the display unit 151 based on multi-touch by the mobile terminal 100 according to the embodiment of the present invention.

Referring to FIG. 3, the controller 180 may adjust the brightness setting value of the display unit 151 based on multi-touch. If the first touch point T1 of the multi-touch and the drag direction of the second point correspond to the first pattern, the controller 180 subtracts the brightness of the first touch point T1 from the brightness setting value immediately before the display unit 151 is switched to the inactive state, The brightness of the display unit 151 can be increased by a size corresponding to the distance. For example, the first pattern may be a pattern in which the interval between the first touch point T1 and the second touch point T2 is away from each other along the first direction (horizontal direction).

The control unit 180 can switch the display unit 151 in which the predetermined operation screen is displayed to the inactive state as shown in FIG. It is assumed that the brightness setting value of the display unit 151 immediately before the switch to the inactive state is 50%.

The control unit 180 can recognize the first touch point T1 and the second touch point T2 of the multi-touch input through the display unit 151, which is in an inactive state. At this time, as shown in FIG. 3 (b), the controller 180 displays the first touch point T1 and the second touch point T2 as the first and second touch points T1 and T2 respectively dragging to the left and right If it corresponds to the pattern, the brightness increase function can be selected as a function to be controlled. In addition, the drag distance of the first touch point T1 and the second touch point T2 may be summed to determine to what extent the brightness setting value is to be increased. For example, assuming that the brightness is preset to increase by 20% every time the drag distance increases by the first distance d1, the drag distance of the first touch point T1 and the second touch point T2 becomes The control unit 180 can increase the brightness setting value of the display unit 151 by 40% in accordance with the second distance 2d which is the total drag distance.

3 (b), the control unit 180 displays a part of the display unit 151 in the active state (i.e., the state of the display unit 151) to enable the user to confirm the function currently controlled according to the multi- So that the guidance message 201 can be displayed. The control unit 180 may continuously display the guidance message 201 in a state where the multi-touch is maintained, or may control the guidance message 201 to disappear after a predetermined time elapses.

3 (c), the control unit 180 controls the brightness of the display unit 151 to be controlled by the control unit 180, %) Can be applied to the display unit 151. At this time, the operation screen displayed on the display unit 151 may be the same as the operation screen displayed immediately before the switch to the inactive state.

3 (a) and 3 (c), as the brightness setting value of the display unit 151 increases through multi-touch, the operation screen of the display unit 151 shown in FIG. 3 (c) It can be confirmed that it is displayed brighter. 3 illustrates a case where the first touch point T1 and the second touch point T2 are both dragged. However, the present invention is not limited to this, and the first touch point T1 and the second touch point T2 T2 may be dragged, the brightness setting value of the display unit 151 may be increased through the same method. Hereinafter, a more detailed description will be given with reference to FIG.

4 is a conceptual diagram for explaining another example of an operation in which the mobile terminal 100 according to the embodiment of the present invention increases the brightness of the display unit 151 based on multi-touch.

4 (a), the first touch point T1 and the second touch point T2 correspond to a first pattern moving away from each other along a first direction (for example, a horizontal direction) , The first touch point T1 is different from that of FIG. 3 (b) in that only the second touch point T2 is dragged to the right in a state where the first touch point T1 is fixed at the first touch position. In this case, the control unit 180 selects the brightness increasing function, which is a function corresponding to the first pattern, as a function to control and displays the first distance d1 based on the first distance d1, which is the drag distance of the second touch point T2, 151) can be increased by 20%.

Referring to FIG. 4B, in contrast to FIG. 4A, the second touch point T2 is fixed to the first touch position, and only the first touch point T1 is dragged to the left have. In this case as well, the interval between the first touch point T1 and the second touch point T2 corresponds to a first pattern that is spaced apart from each other along the first direction. Accordingly, the controller 180 controls the brightness increasing function The brightness setting value of the display unit 151 can be increased by 40% according to the second distance d2 which is the drag distance of the first touch point T1.

In both of the above cases, the control unit 180 may display the guidance messages 202 and 203 through the display unit 151 to guide the increase in the brightness setting value through the multi-touch.

3 and 4, before the display unit 151 is switched from the inactive state to the active state, the brightness setting value of the display unit 151 is increased . For example, in an outdoor environment of sunny weather, the visibility of information displayed on the display unit 151 may be deteriorated due to sunlight. To increase the visibility, the display unit 151 is activated, It is possible to eliminate the inconvenience that the setting menu is called to increase the brightness setting value of the display unit 151 and must be operated through a plurality of touches or the like.

5 is a conceptual diagram illustrating an exemplary operation of the mobile terminal 100 according to the embodiment of the present invention to reduce the brightness of the display unit 151 based on multi-touch.

Referring to FIG. 5, the controller 180 may decrease the brightness setting value of the display unit 151 based on multi-touch. Specifically, when the first touch point (T1) of the multi-touch and the drag direction of the second point correspond to the second pattern, the controller 180 controls the display unit 151 to display the brightness setting value immediately before the display unit 151 is switched to the inactive state The brightness of the display unit 151 can be reduced by a size corresponding to the drag distance. For example, the second pattern may be a pattern in which the interval between the first touch point T1 and the second touch point T2 approaches each other along the first direction (horizontal direction).

The control unit 180 can switch the display unit 151 in which the predetermined operation screen is displayed to the inactive state as shown in FIG. It is assumed that the brightness setting value of the display unit 151 immediately before the switch to the inactive state is 90%.

The control unit 180 can recognize the first touch point T1 and the second touch point T2 of the multi-touch input through the display unit 151, which is in an inactive state. At this time, the controller 180 determines whether the first touch point T1 and the second touch point T2 are dragged to the right and left sides (that is, approaches each other along the horizontal direction) as shown in FIG. 5 (b) When it corresponds to the pattern, the brightness reduction function can be selected as a function to be controlled. In addition, the drag distance between the first touch point T1 and the second touch point T2 may be summed to determine to what extent the brightness setting value is to be reduced. For example, assuming that the brightness is preset to decrease by 20% every time the drag distance increases by the first distance d1, the drag distance of the first touch point T1 and the second touch point T2 becomes The control unit 180 can reduce the brightness setting value of the display unit 151 by 40% corresponding to the second distance 2d which is the total drag distance.

5 (b), the control unit 180 displays a part of the display unit 151 in the active state (i.e., the state of the display unit 151) to enable the user to confirm the function currently controlled according to the multi- So that the guidance message 204 can be displayed. The control unit 180 may continuously display the guidance message 204 in a state where the multi-touch is maintained, or may control the guidance message 204 to disappear when a predetermined time elapses.

5 (b), the controller 180 controls the display unit 151 to display the reduced brightness set value through the above-described procedure on the display unit 151 151). At this time, the operation screen displayed on the display unit 151 may be the same as the operation screen displayed immediately before the switch to the inactive state.

5 (a) and 5 (c), as the brightness setting value of the display unit 151 decreases through multi-touch, the operation screen of the display unit 151 shown in FIG. 5 (c) It can be confirmed that it is darker.

FIG. 6 is a conceptual diagram for explaining another example of the operation of the mobile terminal 100 according to the embodiment of the present invention to reduce the brightness of the display unit 151 based on multi-touch.

6 (a), the first touch point T1 and the second touch point T2 correspond to a second pattern that approaches each other along a first direction (e.g., a horizontal direction) However, the second touch point T2 is different from that of FIG. 5 (b) in that only the first touch point T1 is dragged to the right in a state where the second touch point T2 is fixed at the first touch position. In this case, the controller 180 selects the brightness reduction function, which is a function corresponding to the second pattern, as a function to control, and displays the first distance d1 based on the first distance d1, which is the drag distance of the first touch point T1, 151 can be reduced by 20%.

6B, in contrast to FIG. 6A, only the second touch point T2 is dragged to the left in a state where the first touch point T1 is fixed to the first touch position have. In this case as well, since the interval between the first touch point T1 and the second touch point T2 corresponds to a second pattern that approaches each other along the first direction, the controller 180 determines that the brightness decreases corresponding to the second pattern Function can be controlled to reduce the brightness setting value of the display unit 151 by 40% according to the second distance d2 which is the drag distance of the second touch point T2.

In both of the above cases, the control unit 180 may display the guidance messages 205 and 206 through the display unit 151 to guide the increase in the brightness setting value through the multitouch.

5 and 6, the brightness of the display unit 151 may be reduced in advance according to an external situation before the display unit 151 is switched from the inactive state to the active state. For example, in an indoor environment such as a movie theater, even if the display unit 151 has the same brightness setting value, glare may be greater than in the outdoor environment. When the display unit 151 is switched to the active state to lower the brightness setting value According to the embodiment of the present invention, since the brightness setting value can be lowered in advance without switching the display unit 151 to the active state, It is possible to prevent a glare due to the user or an uncomfortable situation to the other person.

7 is a conceptual diagram for explaining an example of an operation of the mobile terminal 100 according to an embodiment of the present invention to increase the volume set value based on multi-touch.

If the multi-touch corresponds to the third pattern, the control unit 180 can select the function for controlling the volume increase function. For example, the third pattern may be a pattern in which the first touch point T1 and the second touch point T2 are dragged in an upward direction along the second direction (vertical direction). Here, the volume increase function may correspond to at least one of various events related to sound such as playback of a music file, call reception, ringing, and an alarm sound.

Referring to FIG. 7A, the control unit 180 may play a predetermined music file by driving the music playback application in the inactive state of the display unit 151. FIG. At this time, it is assumed that the volume setting value related to the reproduction of the music file is 30%.

Referring to FIG. 7B, as the first touch point T1 and the second touch point T2 of the multi-touch are dragged vertically along the vertical direction, the controller 180 performs a volume increase function You can select the function to control. At this time, assuming that the volume setting value is set to increase by 15% each time the drag distance increases by the first distance d1, the controller 180 controls the first touch point T1 and the second touch point T2 The music file can be reproduced by increasing the volume setting value by 30% corresponding to the second distance d2 which is a distance that is dragged side by side. 7 (b), the control unit 180 displays a part of the display unit 151 in the active state (i.e., the state of the display unit 151) in order to allow the user to confirm the function currently controlled according to the multi- So that the guidance message can be displayed.

8 is a conceptual diagram for explaining an example of an operation in which the mobile terminal 100 according to the embodiment of the present invention reduces a volume set value based on multi-touch.

If the multi-touch corresponds to the fourth pattern, the control unit 180 can select the function for controlling the volume reduction function. For example, the fourth pattern may be a pattern in which the first touch point T1 and the second touch point T2 are dragged downward along the second direction (vertical direction). Here, the volume reduction function may correspond to at least one of various events related to sound such as reproduction of a music file, call reception, ringing, and an alarm sound.

Referring to FIG. 8 (a), the controller 180 may play a predetermined music file by driving the music playback application in the inactive state of the display unit 151. At this time, it is assumed that the volume setting value related to the reproduction of the music file is 60%.

Referring to FIG. 8B, as the first touch point T1 and the second touch point T2 of the multi-touch are dragged downward along the vertical direction, the controller 180 performs a volume reduction function You can select the function to control. At this time, assuming that the volume setting value is set to be lowered by 15% each time the drag distance increases by the first distance d1, the controller 180 controls the first touch point T1 and the second touch point T2 The music file can be reproduced by reducing the volume setting value by 15% corresponding to the first distance, which is the distance that is dragged side by side. 8 (b), the control unit 180 displays a part of the area of the display unit 151 in the active state So that the guidance message can be displayed.

Meanwhile, although not shown, when the total drag distance of one touch point of the multi-touch and the second touch point T2 corresponding to the fourth pattern reaches a predetermined distance or more, the controller 180 may enter the vibration mode . When a predetermined event (e.g., call reception) occurs in the vibration mode, the control unit 180 can generate a tactile effect instead of the auditory effect.

9 is a conceptual diagram for explaining an example of an operation of the mobile terminal 100 according to an embodiment of the present invention to display a predetermined object on the display unit 151 based on multi-touch.

If the multi-touch corresponds to the fifth pattern, the control unit 180 can display a predetermined object by switching a portion of the display unit 151 to an active state. Hereinafter, for convenience of description, the fifth pattern is a pattern in which the first touch point T1 and the second touch point T2 are respectively dragged upward and downward along the second direction (e.g., vertical direction) It is assumed that the predetermined object to be displayed is at least one or more icons, and the description will be continued.

9A, the first touch point T1 for the display unit 151 in an inactive state is dragged up along the vertical direction, and the second touch point T2 is dragged downward along the vertical direction The control unit 180 switches the partial area of the display unit 151 to the activated state and displays at least one icon 301, 302, 303, 304 in the activated area as shown in FIG. 9 (b) Can be displayed. At this time, the icons displayed in the activated area may correspond to different application programs stored in the memory 170. [ For example, the first icon 301 may be a music playing application, the second icon 302 may be a multimedia playing application, the third icon 303 may be a messenger application, and the fourth icon 304 may be a messaging application. 9 (b) shows that the multi-touch is not released but the control unit 180 displays the predetermined icon even if the multi-touch is released after the predetermined icon is displayed in the activated area, The predetermined icon may be continuously displayed or may disappear from the active area after a predetermined period of time elapses.

At this time, the controller 180 may designate the display position of the active area according to the coordinates of the first touch point T1 or the second touch point T2. For example, the control unit 180 may vary the position of the active area such that any one of the first touch point T1 or the second touch point T2 is located at the center of the active area. As another example, the control unit 180 may place the activation region between the first touch point T1 and the second touch point T2 as another example.

When the controller 180 receives a touch on any one of the icons displayed in the active area, the controller 180 can execute an application program corresponding to the touched icon. For example, when the fourth icon 304 corresponding to the message application among the icons displayed in the active area is selected, the control unit 180 can drive the message application program. At this time, the controller 180 switches the entire display unit 151 to the active state simultaneously with the touch of the icon, and displays the operation screen of the corresponding application program or can execute the application program internally while maintaining the disabled state .

10 is a conceptual diagram for explaining another example of an operation in which the mobile terminal 100 displays a predetermined object on the display unit 151 based on multi-touch according to an embodiment of the present invention.

The controller 180 can change the number of icons displayed in the active area according to the distance that the multi-touch corresponding to the fifth pattern is dragged. That is, the controller 180 may increase the number of icons displayed in the active area as the distance to which the multi-touch corresponding to the fifth pattern is dragged increases.

For example, referring to FIG. 10A, as the first touch point T1 corresponding to the fifth pattern and the drag distance of the second touch point correspond to the first distance d1, respectively, The controller 180 can display a total of four icons 301, 302, 303, and 304 in the active area.

10 (b), as the drag distance of the first touch point T1 and the second touch point corresponding to the fifth pattern increases to correspond to the second distance d2, respectively, The control unit 180 may display a total of six icons 301, 302, 303, 304, 305, and 306 in the activation area. That is, the number of icons displayed in the active area may be larger than when the drag distance is the first distance d1.

According to the embodiment described above with reference to FIG. 10, since the number of icons displayed on the display unit 151 can be varied through the multi-touch which merely makes the drag distance long or short, user convenience can be increased.

On the other hand, the icon to be displayed on the display unit 151 according to the third pattern described above with reference to Figs. 9 and 10 can be set or changed based on user input.

11 is an exemplary diagram for explaining an example of an operation in which the mobile terminal 100 according to the embodiment of the present invention changes a screen display direction based on multi-touch.

If the multi-touch corresponds to the sixth pattern, the control unit 180 can switch the screen display mode of the display unit 151 to the portrait view mode.

Referring to FIG. 11 (a), the controller 180 may switch the display unit 151 in the landscape view mode to an inactive state. In order to change the screen display mode to the landscape view mode according to the related art, after the display unit 151 is activated, the gravity sensor of the sensing unit 140 determines the position of the main body 100 of the mobile terminal 100 There is a need to tilt the mobile terminal 100 so that the mobile terminal 100 can recognize the mobile terminal 100.

Referring to FIG. 11B, the controller 180 may switch the screen display mode of the display unit 151 to the portrait view mode if the multi-touch corresponds to the sixth pattern. For example, in the sixth pattern, the y-coordinate of the first touch point T1 increases while the x-coordinates of the first touch point T1 and the second touch point T2 remain equal to each other, T2 may be a decreasing pattern.

11C, when the display unit 151 is switched back to the active state, the operation screen is displayed on the display unit 151 in the portrait view mode without tilting the mobile terminal 100 Can be displayed.

12 is an exemplary diagram for explaining another example of an operation in which the mobile terminal 100 according to the embodiment of the present invention changes the screen display direction based on multi-touch.

If the multi-touch corresponds to the seventh pattern, the control unit 180 can switch the screen display mode of the display unit 151 to the landscape view mode.

The control unit 180 can switch the display unit 151 in the vertical viewing mode to the inactive state as shown in FIG. 11 (b), as shown in FIG. 12 (a). If the multi-touch corresponds to the seventh pattern, the control unit 180 can switch the screen display mode of the display unit 151 to the landscape view mode. For example, in the seventh pattern, while the y-coordinates of the first touch point T1 and the second touch point T2 are kept equal to each other, the interval between the first touch point T1 and the second touch point T2 becomes large The x coordinate of the first touch point T1 decreases and the x coordinate of the second touch point T2 increases.

12C, when the display unit 151 is switched back to the active state, the operation screen is displayed on the display unit 151 in the landscape view mode without tilting the mobile terminal 100 Can be displayed.

According to the embodiment described above with reference to Figs. 11 and 12, since the orientation of the screen can be changed in a direction easy for the user to view without changing the posture of the mobile terminal 100 placed substantially horizontally on the ground, Can be increased.

13 is an exemplary diagram for explaining an operation of the mobile terminal 100 according to the embodiment of the present invention to limit the upper limit value of the brightness setting value of the display unit 151 based on the measured values of the surrounding environment.

The controller 180 may determine an upper limit value of the brightness setting value of the display unit 151 that can be adjusted through the multitouch based on the illuminance measurement value provided from the illuminance sensor 142. [ Specifically, the upper limit value of the brightness setting value corresponding to the different illuminance measurement value may be stored in advance in the memory 170, and the controller 180 may display the current illumination measurement value on the display 170 based on the information stored in the memory 170, It is possible to control the brightness setting value for the unit 151 not to exceed the predetermined value.

For example, referring to FIG. 13A, when the multi-touch corresponds to the first pattern, the controller 180 determines whether the first touch point T 1 and the second touch point T 2 are dragged The upper limit value for increasing the brightness setting value may be limited to 50% when the brightness measurement value provided from the brightness sensor 142 corresponds to 'low'.

The brightness setting value set to 10% before the input of the multi-touch is set such that the drag distance between the first touch point T1 and the second touch point T2 gradually increases to the first distance d1 as shown in FIG. 13 (a) And can increase to 50%. However, since the upper limit value of the brightness setting value is limited to 50% by the control unit 180, even if the drag distance continuously increases as shown in FIG. 13B, the brightness setting value of the display unit 151 exceeds 50% It is not controlled. That is, the user can recognize that the screen brightness is maintained at 50% through the guide message 209 even though the drag distance increases.

Accordingly, by lowering the maximum value of the brightness setting value that can be increased through the multi-touch operation for the display unit 151 which is in the inactive state in a low illuminance environment (e.g., a movie theater), the user can be inadvertently disturbed It is possible to prevent the situation beforehand.

14 is an exemplary diagram for explaining an operation of the mobile terminal 100 according to the embodiment of the present invention to limit the lower limit value of the brightness setting value of the display unit 151 based on the measured values of the surrounding environment.

The controller 180 may determine a lower limit value of the brightness setting value of the display unit 151 that can be adjusted through the multitouch based on the illuminance measurement value provided from the illuminance sensor 142. [ Specifically, the memory 170 may store a lower limit value of the brightness setting value corresponding to the different illuminance measurement value in advance, and the controller 180 may display the current illuminance measurement value on the display 170 based on the information stored in the memory 170, It is possible to control so that the brightness setting value for the unit 151 does not become less than the predetermined value.

For example, referring to FIG. 14 (a), when the multi-touch corresponds to the second pattern, the controller 180 determines whether the first touch point T1 and the second touch point T2 are dragged The lower limit value for reducing the brightness setting value may be limited to 70% when the brightness measurement value provided from the brightness sensor 142 is 'high'.

It is assumed that the total drag distance of the first touch point T1 and the second touch point T2 is less than the first distance T1 as shown in Figure 14 (a), assuming that the brightness setting value is 90% d1), the brightness setting value can be reduced from 90% to 70%. However, since the lower limit value of the brightness setting value is limited to 70% by the control unit 180, even if the drag distance continues to increase (e.g., d2> d1 / 2) The brightness setting value is not adjusted to less than 70%. That is, as shown in FIG. 13 (b), the user can recognize that the screen brightness is maintained at 70% even though the drag distance is increased through the guide message 210.

Accordingly, by increasing the minimum value of the brightness setting value that can be reduced through the multi-touch to the display unit 151 that is in the inactive state in an environment with high illumination (e.g., outdoor), the display unit 151, The visibility of the information displayed on the display screen is lowered.

15 is an exemplary diagram for explaining an operation in which the mobile terminal 100 according to the embodiment of the present invention limits the upper limit value of the volume setting value based on the measured values of the surrounding environment.

The control unit 180 may determine an upper limit value of the brightness setting value of the display unit 151 that can be adjusted through the multitouch based on the noise measurement value provided from the microphone 122. [ That is, the microphone 122 may measure the external noise and provide the noise measurement value to the control unit 180 when the display unit 151 is in the inactive state. Specifically, the upper limit value of the volume setting value corresponding to the different noise measurement value may be stored in advance in the memory 170, and the controller 180 may correspond to the current noise measurement value based on the information stored in the memory 170 The volume setting value of the mobile terminal 100 can be controlled not to exceed the predetermined value in the external environment.

For example, referring to FIG. 15A, when the multi-touch corresponds to the third pattern, the controller 180 determines whether the multi-touch corresponds to the first touch point T1 and the second touch point T2, The upper limit value for increasing the volume setting value may be limited to 60% when the measured noise value provided from the microphone 122 corresponds to 'low'. If the volume is high even though there is no or very little noise of the external environment, the hearing ability of the user may be damaged or the sound output from the mobile terminal 100 may cause inconvenience to others.

The volume setting value set to 55% before the input of the multi-touch increases to 60% as the drag distance between the first touch point T1 and the second touch point T2 gradually increases as shown in FIG. 15 (a) . However, since the upper limit value of the volume setting value is limited to 60% by the control unit 180, the volume setting value is not adjusted beyond 60% even if the drag distance is continuously increased as shown in FIG. 15 (b).

16 is an exemplary diagram for explaining an operation in which the mobile terminal 100 according to the embodiment of the present invention limits the lower limit value of the volume setting value based on the measured values of the surrounding environment.

The control unit 180 can determine the lower limit value of the brightness setting value of the display unit 151 that can be adjusted through the multitouch based on the noise measurement value provided from the microphone 122. [ Specifically, the lower limit value of the volume setting value corresponding to the different noise measurement value may be stored in the memory 170 in advance, and the controller 180 may correspond to the current noise measurement value based on the information stored in the memory 170 The volume setting value of the mobile terminal 100 may not be lowered below a predetermined value.

For example, referring to FIG. 16A, when the multi-touch corresponds to the fourth pattern, the controller 180 determines whether the first touch point T 1 and the second touch point T 2 are dragged If the noise measurement value provided from the microphone 122 corresponds to 'high', the lower limit value for reducing the volume set value may be limited to 80%. If the noise of the external environment is relatively high, the user can be heard only when the volume set value is equal to or higher than a predetermined level.

The volume setting value set to 90% before the multi-touch input is decreased to 80% as the drag distance between the first touch point T1 and the second touch point T2 gradually increases as shown in FIG. 16 (a) . However, since the lower limit value of the volume setting value is limited to 80% by the control unit 180, the volume setting value is not adjusted to be smaller than 80% even if the drag distance is continuously increased as shown in (b) of FIG.

17 is an exemplary diagram for explaining an operation in which the mobile terminal 100 sets a communication mode based on multi-touch according to an embodiment of the present invention.

The controller 180 may turn on or off at least one of functions related to communication of the mobile terminal 100 when the multi-touch corresponds to the eighth pattern. The functions related to communication may be various such as Wi-Fi, Bluetooth, GPS, NFC, and the Wi-Fi function is assumed to be controlled for convenience in FIG. At this time, the eighth pattern related to the control of the Wi-Fi function may be a pattern in which the first touch point T1 and the second touch point T2 are separated from each other along the third direction (e.g., the diagonal direction).

Referring to FIG. 17A, when the controller 180 recognizes that the multi-touch input through the display unit 151, which is in a deactivated state when the Wi-Fi function is OFF, is the eighth pattern, It can be switched to the ON state. At this time, the control unit 180 may display a guidance message 212 for switching a part of the display unit 151 to the active state and informing the user that the Wi-Fi function has been changed to the ON state. Also, although not shown, it goes without saying that the controller 180 may turn off the Wi-Fi function when the multi-touch corresponding to the eighth pattern is re-input.

On the other hand, the control unit 180 virtually divides the display unit 151 into a plurality of areas, and can link each area with different functions. For example, the control unit 180 may divide the display unit 151 into four regions as shown in FIG. 17 (b). At this time, the first area A may correspond to a Wi-Fi function, the second area B may correspond to a Bluetooth function, the third area C may correspond to a GPS function, and the fourth area D may correspond to an NFC function.

The control unit 180 can selectively turn on or off any one of the different functions related to communication according to the area where the eighth pattern is inputted through the multitouch. For example, when the eighth pattern is input in the second area B as shown in FIG. 17B, the controller 180 can turn on or off the Bluetooth function corresponding to the second area B. That is, even if the same pattern is used, various functions can be controlled individually according to the position where the pattern is input, so that the display unit 151 of a limited size can be efficiently utilized.

18 is an exemplary diagram illustrating an operation in which the mobile terminal 100 controls two or more functions based on multi-touch according to an embodiment of the present invention.

When two or more patterns are successively input through the multi-touch, the controller 180 may control two or more different functions sequentially or simultaneously according to each pattern. That is, when the multi-touch is not released and the pattern is changed from the original pattern to another pattern, the control unit 180 can control not only the function corresponding to the initial pattern but also the function corresponding to the pattern to be subsequently inputted.

For example, as shown in FIG. 18 (a), the controller 180 controls the first touch point T1 and the second touch point T2 to move away from each other along the horizontal direction The brightness setting value set on the display unit 151 can be increased through the brightness increasing function.

Thereafter, as the multi-touch changes from the position at which the first pattern is terminated to the third pattern (see Fig. 3) that moves upward along the vertical direction as shown in Fig. 18B, It is possible to increase the volume set value corresponding to the drag distance of the pattern.

Next, as the multi-touch changes from the position where the third pattern is terminated to the fifth pattern (see FIGS. 9 and 10), the control unit 180 switches one area of the display unit 151 to the active state, The number of icons corresponding to the drag distance of the pattern can be displayed.

This makes it possible to control two or more different functions through a series of successive multi-touches, so that it is possible to reduce the cumbersome task of repeatedly performing input corresponding to each function in order to control various functions.

2 to 18, the mobile terminal 100 according to the present invention can display various kinds of information based on multi-touch on the display unit 151 even when the display unit 151 is in the inactive state Function can be executed. That is, since the conventional operation method, which was possible only when the display unit 151 is in the activated state, can be partially expanded to the inactive state, not only a new user interface can be provided, but also the power consumption of the mobile terminal 100 is significantly The portability of the mobile terminal 100 can be improved.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
