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.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. 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.

The display unit 151 displays (outputs) information processed by the mobile terminal 100.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal 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.

In the following description, referring to the accompanying drawings, when at least two images in one drawing (FIG. N) are shown in the form of 2 by 2, the image shown at the upper left is referred to as " The image shown at the top is referred to as "the second drawing", the image shown at the lower right is referred to as "the third drawing", and the image shown at the lower left is referred to as "fourth drawing".

On the other hand, when at least two images in one drawing (FIG. N) are shown in a line from top to bottom, the images at the top are sequentially referred to as "first drawing, second drawing, ..." .

The mobile terminal according to an exemplary embodiment of the present invention, which may include at least one of the above-described components, may sense a touch applied to the display unit 151. Specifically, the controller 180 may sense a touch on the display unit 151 using the sensing unit 140 (sensing unit 140).

The controller 180 can perform a specific function in response to the touch being applied when the display unit 151 is in the active state (ON state) have. For example, when a touch is applied to an icon of an application displayed on the activated display unit 151, the control unit 180 can execute an application corresponding to the icon to which the touch is applied and output an execution screen of the application .

Meanwhile, the controller 180 can sense a touch on the display unit 151 even when the display unit 151 is in an inactive state. Here, the display unit 151 is in the inactive state, which means that only the display unit 151 is turned off in the state that the mobile terminal 100 is powered on. That is, the display unit 151 is in the inactive state, which means that no display information is displayed on the display unit 151 as the illumination, panel, light emitting element, etc. of the display unit 151 are turned off . The control unit 180 can switch the display unit 151 to the active state when a user request is detected (e.g., when the power button is pushed) while the display unit 151 is in the inactive state. Here, the activation of the display unit 151 may mean that the display unit 151 is in an ON state. In addition, various display information may be displayed on the activated display unit 151. FIG.

The control unit 180 may supply the minimum power to the sensing unit 140 that senses the touch applied to the display unit 151 while the display unit 151 is in the inactive state. Here, the minimum power means a minimum power required to sense a touch on the display unit 151 in which the sensing unit 140 is in an inactive state, and may be determined according to a hardware characteristic of the sensing unit or a user setting . Here, the sensing unit 140 for sensing the touch may be, for example, a touch sensor.

Meanwhile, when a touch is applied to the display unit 151, the control unit 180 can determine the area (area) of the touch, the number of points where the touch is applied, and the like. Specifically, when a touch is applied to the display unit 151, the control unit 180 receives the signal (s) generated in response to the touch from the sensing unit 140 (for example, a touch sensor) It is possible to determine which area of the display unit 151 is touched, the number of points (areas) where the touch is made, and the size (area size) of the touched area (s).

If the touch sensed by the sensing unit 140 satisfies a predetermined condition, the controller 180 may perform a function associated with the touch that satisfies the predetermined condition.

Meanwhile, the controller 180 of the mobile terminal 100 according to an exemplary embodiment of the present invention may generate vibration based on a touch applied to the display unit 151. Specifically, when the display unit 151 is kept in a state of being touched, the control unit 180 can generate vibration. The vibration may be generated by a haptic module 153.

The haptic module 153 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated in the haptic module 153 can be controlled by the user's selection or the setting of the control unit. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output the vibrations.

The control unit 180 may generate the vibration every predetermined time period while the touch applied to the display unit 151 is maintained. That is, if the touch is maintained after the display unit 151 is touched, the control unit 180 may generate at least one vibration while the touch is maintained. Specifically, when the touch is maintained, the controller 180 can generate vibration at a predetermined time interval (every predetermined time elapses).

Here, the vibration means that the mobile terminal shakes and stops for a predetermined time. That is, the control unit 180 can stop generating vibration for a predetermined time based on the fact that the touch is maintained.

The controller 180 may determine that the vibration generated during the predetermined time is once (once) vibrated when the vibration is generated for a predetermined time and stops. The predetermined time may be determined by user setting.

For example, when the touch applied to the display unit 151 is continuously maintained, the controller 180 stops the vibration after generating the vibration for a predetermined period of time (vibration occurs once) The vibration can be stopped after generating the vibration for the time (one vibration occurs). Thereafter, when the touch held on the display unit 151 is released, the controller 180 may not generate vibration any more. In this case, the control unit 180 can determine that the vibration is generated twice (twice) while the touch is maintained.

The control unit 180 may perform a preset function based on the number of vibrations generated while the touch is held. The predetermined function may include all functions executable in the mobile terminal, and may associate a specific function with the number of vibrations by user setting. For example, when the vibration is generated twice (when the number of vibrations is two) and the specific function is performed, the controller 180 generates vibration two times while the touch is maintained, The specific function can be performed. For example, the specific function may be a function of releasing the lock state.

The locking state is a state in which the execution of the function of the mobile terminal is restricted, and is implemented so that it is released based on a password or a pattern previously set by a user. However, the password or pattern is vulnerable to security because the user's motion and visual elements are included.

On the other hand, the vibration described above is a non-visual element, and can not be visually or audibly detected by the user other than the user using the mobile terminal. Accordingly, the mobile terminal according to an embodiment of the present invention generates a non-visual vibration and performs a predetermined function (lock state releasing function) based on the number of vibrations in which the vibration occurs, / UX can be provided.

Hereinafter, with reference to the accompanying drawings, a method of generating vibration (a method of controlling) while a touch is held on a display unit and a method of performing a predetermined function based on the number of vibrations generated by the vibration More specifically,

FIG. 2 is a flowchart illustrating an exemplary control method of the present invention, and FIG. 3 is a conceptual diagram illustrating a control method illustrated in FIG. 2. Referring to FIG.

First, in the present invention, a step of detecting a touch applied to the display unit 151 proceeds (S210).

Specifically, when the touch object (e.g., a finger or the like) is applied to the display unit 151, the controller 180 may detect that the touch 310 is applied through the sensing unit 140. [

The sensing unit 140 may sense a touch on the display unit 151 when the display unit 151 is in the active state or in the inactive state. To this end, the sensing unit 140 may be supplied with a minimum power for sensing a touch.

Thereafter, at least one vibration 320 is generated while the touch 310 is held, and when the held touch 310 is released, based on the number of vibrations generated while the touch 310 is held, A step S220 of performing the set function is performed.

The fact that the touch 310 is held may mean that the touch object is not released to the display unit 151 in a state of being in contact with the touch object. That is, the controller 180 may determine that the touch is maintained if the applied touch is not released but continues to be sensed after the touch is applied to the display unit 151. [ As an example, an embodiment in which the touch 310 is held may be a long touch or a drag touch.

The control unit 180 may generate at least one vibration while the touch 310 is held on the display unit 151. [ The vibration 320 may mean that the mobile terminal shakes for a predetermined time, as described above. When the vibration is generated for a predetermined time, the controller 180 may determine that the vibration generated during the predetermined time has been vibrated once.

The control unit 180 may generate at least one vibration 320 while the touch 310 is being held. That is, the vibration 320 may be generated every predetermined time while the touch 310 is held on the display unit 151. Specifically, the control unit 180 generates the vibration 320 for a predetermined time while the touch 310 is held on the display unit 151, and generates the vibration 320 for a predetermined time again after a predetermined time elapses . The vibration 320 may continue to be generated every time the predetermined time elapses when the touch 310 is maintained. Here, if the control unit 180 generates a frequency more than a predetermined number of times by user setting, the controller 180 may not generate the vibration 320 any more. This is to prevent the battery of the mobile terminal from being consumed indiscriminately.

When the touch 310 held on the display unit 151 is released, the controller 180 may perform a preset function based on the number of vibrations generated while the touch 310 is held. Specifically, the controller 180 may perform a function associated with the number of vibrations generated while the touch 310 is held.

Specifically, each of the functions executable in the mobile terminal 100 may be associated with conditions for executing each function. For example, the first function may be associated with three oscillation times, and the second function different from the first function may be associated with four oscillation times. In this case, when the touch applied to the display unit 151 is released and then released, the controller 180 performs the first function when three vibrations occur while the touch is maintained, The second function can be performed.

For example, information about a predetermined number of times of vibration (for example, four times) may be associated with a specific function among the functions executable in the mobile terminal 100. In this case, when the touch 310 is released after the vibration is generated for the predetermined number of vibrations while the touch 310 is held on the display unit 151, To perform certain functions.

For example, when the mobile terminal 100 is in the locked state 300a, the controller 180 determines that the number of vibrations 320 generated while the touch is maintained coincides with the vibration frequency associated with the function of releasing the lock state , The lock state can be canceled (300b).

Meanwhile, when at least two taps are applied to the display unit 151 at different points of time and the at least two taps are held for a predetermined time and then released, the controller 180 holds the at least two taps A predetermined function can be performed based on the number of vibrations generated during the operation.

Specifically, the controller 180 maintains a state in which the first touch of the at least two touches is applied to the display unit 151, and when the first touch is released, The user can perform a preset function based on the number of vibrations generated while the first touch is maintained and the number of vibrations generated while the second touch is maintained.

That is, the various functions that are executable in the mobile terminal 100 may be associated with various conditions for executing each function. For example, a specific function may be associated with three vibrations while the first touch is held and with conditions corresponding to four vibrations while the second touch is applied within a reference time after the first touch is released Can be.

In this case, the control unit 180 releases the first touch after the vibration is generated three times while the first touch is maintained, and the second touch is released within the reference time after the first touch is released, When the second touch is released after the vibration is generated four times while the first touch is released, the specific function can be performed.

Here, the reference time means a time between a point at which the touch is released and a point at which a new touch is applied, which can be set by the user.

The above description will be more clearly understood with reference to FIG.

Referring to FIG. 3, the sensing unit 140 may sense a touch 310 applied to the display unit 151. The control unit 180 may generate at least one vibration 320 while the touch 310 is held when the touch 310 is held in a state of being touched on the display unit.

The axis shown on the right side of the first drawing of Fig. 3 means the time axis. The controller 180 may generate the vibration 320 every time the predetermined time elapses when the touch 310 is maintained in a touch state. Thereafter, the controller 180 may determine the number of vibrations occurring while the touch 310 is maintained in the state of being applied to the display unit 151. Thereafter, the control unit 180 may perform a function associated with the predetermined function, that is, the vibration frequency, based on the vibration frequency.

For example, as shown in the second diagram of FIG. 3, the number of vibrations generated while the touch 310 is held is four, and the function of releasing the lock state is linked to the vibration frequency of four times The control unit 180 can release 300b the mobile terminal 100 in the locked state 300a based on the number of times of vibration generated while the touch 310 is held (four times).

Also, the controller 180 may switch the inactive display unit to an active state based on the number of times of vibration generated while the touch 310 is held. Here, when the mobile terminal 100 is in the locked state, the control unit 180 can release the locked state together with switching the display unit in the inactive state to the active state. That is, the function of switching the display unit 151 to the active state and the function of releasing the locked state can be performed by only one touch input.

Meanwhile, the present invention can control vibrations in various ways while the touch is maintained. Hereinafter, a method of controlling vibration in the present invention will be described in more detail with reference to the accompanying drawings.

4A, 4B, 4C, 5A, and 5B are conceptual diagrams for explaining a method of controlling vibration generation based on a touch applied to a display unit.

As described above, when the display unit 151 is kept in a state in which a touch is applied, the controller 180 can generate the vibration 320 every time a predetermined time elapses. Here, the preset time means a time period between the first vibration and the second vibration generated after the first vibration is generated, and the predetermined time may be kept constant or may be changed. That is, if at least two vibrations occur, there is a time interval between vibration and vibration, and if there are at least two time intervals, the controller 180 sets the at least two time intervals equal It can be controlled or controlled differently. The fact that the at least two time intervals are different from each other may mean that the vibration is generated aperiodically.

4A to 4C, a case where the time interval is constant will be described in detail.

The controller 180 can generate the vibration 320 at a predetermined time interval 430a when the touch 410a is held on the display unit 151 as shown in FIG. Specifically, the vibration 320 may be generated at a predetermined time interval 430a while the touch 410a is held on the display unit 151. [

On the other hand, the control unit 180 can control the time interval at which the vibration is generated based on the size of the area to which the touch is applied on the display unit. Specifically, the time interval may vary based on the size of the area to which the touch is applied.

For example, as shown in FIG. 4A, the controller 180 may generate the vibration 320 in a first time interval 430a if the touch 410a is held in a region having a first magnitude. 4B, when the touch 410b is held in a region having a second size larger than the first size, the controller 180 determines that the touch 410b is in a second time interval shorter than the first time interval 430a And the vibration 320 can be generated by the vibration damper 430b.

Further, when the touches 410c and 410d are held in at least two areas, the controller 180 may determine a time interval during which the vibration is generated based on the sum of the sizes of the at least two areas.

For example, as shown in FIG. 4C, when the touches 410c and 410d are held in at least two areas (points), the controller 180 determines the size of the areas to which the touches 410c and 410d are applied Can be determined. Then, based on the sum of the sizes of the regions, a time interval 430c at which the vibration 320 is generated can be determined.

4A, when the touches 410c and 410d are applied to at least two regions as shown in FIG. 4C, the controller 180 determines whether the sum of the sizes of the at least two regions is equal to or greater than the sum The vibration 320 can be generated at a time interval 430c shorter than the time interval 430a generated in FIG. 4A based on the fact that the touch 410a is larger than the size of the sensed area.

According to the present invention, the time interval during which the vibration is generated is controlled differently based on the size of the area to which the touch is applied, so that the vibration can be generated at different times even if the touch is maintained for the same time. Therefore, even if the time when the touch is maintained by another person is detected, the present invention can enhance security by controlling the number of times of vibration differently. In addition, when it is desired to generate the vibration as many times as the desired number of vibrations, the time interval in which the vibrations are generated can be shortened by only increasing the size of the area to be touched, thereby improving convenience and promptness of the user.

On the other hand, the controller 180 can generate the vibration periodically at different time intervals while the touch is maintained.

In Figs. 5A and 5B, it is shown that the vibrations are generated non-periodically so as to have different time intervals.

5A, the controller 180 may generate the vibrations 320 to have different time intervals 450a, 450b, and 450c while the touch 440a is maintained. Whether the vibration 320 is generated at a predetermined time interval or at a different time interval may be determined by user setting or control of the controller. For example, when a touch is applied to one point (area), the controller 180 may generate the vibration 320 at a predetermined time interval or at a different time interval while the touch is maintained by user setting .

On the other hand, the control unit 180 can determine whether to generate the vibration 320 at a predetermined time interval or at a different time interval based on the number of touch points on the display unit 151. Specifically, whether the vibration 320 is generated non-periodically may be determined based on the number of points where the touch is applied to the display unit.

For example, as shown in FIG. 4A, when the touch 410a is held at one point (area), the controller 180 may generate the vibration 320 to have a constant time interval 430a. As another example, if the touches 440b and 440c are held in at least two points (regions), as shown in Fig. 5b, the controller 180 may move the vibrations 320 at different time intervals 450d, 450e, and 450f, Can be generated.

If the number of vibrations generated while the touch is maintained, regardless of whether the vibrations 320 are generated at a predetermined time interval or at different time intervals, the controller 180 controls the predetermined vibration The function associated with the number of times can be performed.

With this configuration, the present invention can change the time for holding the touch to generate a predetermined number of vibrations by generating vibration at different time intervals while the touch is maintained. Accordingly, the present invention can provide UI / UX with enhanced security.

Meanwhile, the controller 180 may perform different functions when vibration is generated by a preset number of times at predetermined time intervals and when vibration is generated a predetermined number of times at different time intervals. For example, as shown in FIG. 4A, when vibration is generated four times at regular time intervals, the control unit 180 performs the first function and, as shown in FIG. 5B, vibrates at different time intervals The second function may perform a second function different from the first function.

With this configuration, the present invention can provide a new user interface that performs different functions depending on whether the time interval is periodic or non-periodic.

Meanwhile, in the present invention, vibration is generated while a drag touch is applied to the display unit 151, and a predetermined function is performed based on the number of vibrations generated during the drag touch and the direction of the drag touch have. Hereinafter, with reference to the accompanying drawings, a method of performing a predetermined function based on the drag touch will be described in more detail.

FIGS. 6A, 6B, and 6C are conceptual diagrams for explaining a method of performing a predetermined function based on a dragging touch on the display unit. FIG. 7A and FIG. FIG. 2 is a conceptual diagram for explaining a method of controlling vibration generation.

The dragging may be a touch which starts from at least one point of the display unit 151 and extends in one direction. That is, since the dragging touch refers to a touch that moves in one direction while the touch is maintained on the display unit 151, it can be understood that the touch is maintained on the display unit 151 that the dragging is applied.

The control unit 180 may generate at least one (one) vibration while the dragging touch is applied when the dragging touch extending from the at least one point to the display unit 151 is applied. Then, when the dragging is canceled, the controller 180 may perform a predetermined function based on the number of vibrations generated during the dragging and the direction of the dragging.

For example, as shown in the first drawing of FIG. 6A, when a dragging touch 600 applied in one direction 610a to the display unit 151 in an inactive state is detected, At least one oscillation 320 may be generated while the oscillator 600 is applied. When the dragging touch 600 is released, the controller 180 determines whether the number of times of vibration (for example, 3) generated during the dragging of the dragging touch 600 and the direction of the dragging 610a (For example, a function of activating (350b) the display unit 151 which is the inactive state 350a).

Meanwhile, although not shown, the controller 180 may perform different functions depending on the direction in which the drag touch 600 is applied. Specifically, when the number of vibrations generated during the drag touch 600 is equal (for example, three times), the controller 180 determines that the drag touch 600 is applied in the first direction And perform a second function different from the first function based on whether the drag touch 600 is applied in a second direction different from the first direction.

The directions (first and second directions) in which the drag touch is applied can be variously defined. For example, the direction in which the drag-touch is applied may include not only the up, down, left, and right directions but also diagonal direction, clockwise-counterclockwise direction, and the like.

Meanwhile, although not shown, the control unit 180 may perform different functions depending on the number of points at which dragging starts. For example, when the dragging started at one point is released after a predetermined number of vibrations are generated while the dragging started from one point is applied in one direction, the controller 180 can perform the first function. On the other hand, if the drag touch that is simultaneously started at the at least two points after the predetermined number of vibrations occur while the drag touch simultaneously started in at least two points is applied in the one direction, the controller 180 controls the first function The second function can be performed.

On the other hand, the vibration frequency and the direction of the drag touch for performing the preset function can be set variously.

For example, as a condition for performing a preset function, the preset function may include "three vibrations when moving in the first direction 610a and two vibrations when moving in the second direction 610b by one drag touch "May be linked.

6B, the controller 180 generates three vibrations 320 while the drag touch 600 is applied in the first direction 610a, and then the dragging touch 600 When the dragging touch 600 is released after two vibrations 320 are generated while the dragging touch 600 is being applied in the second direction 610b different from the first direction while the first vibration is maintained, It is possible to perform a predetermined function (for example, a function of switching the display unit 151, which is the inactive state 350a, to the active state 350b).

As another example, when at least two drag taps are applied at different points in time, the control unit 180 determines whether the at least two drag taps are applied based on the number of vibrations generated while the at least two drag taps are applied, The set function can be performed. That is, if at least two drag taps are applied at different points of time, the controller performs different functions based on the number of times the at least two drag taps are applied, as well as the number of times the at least two drag taps are applied .

For example, as a condition for performing the first function, the first function may be set to "when the first drag touch moves three times in the first direction, the first drag touch is released and the second drag touch Occurrence of two vibrations upon movement in the second direction ".

6C, when the first drag touch 600a is applied to the display unit 151 in the first direction 610a, the control unit 180 controls the vibration 320 Three times, and the first drag touch 600a may be released as shown in the second drawing of Fig. 6C. 6C, when the second drag touch 600b is in the second direction 610b within the reference time from when the first drag touch 600a is released, The vibration 320 is generated twice while the second drag touch 600b is released and the first function can be performed as shown in FIG.

The first function may be a function of switching the display unit 151, which is the inactive state 350a, to the active state 350b, for example, as shown in FIG. 6C. If the mobile terminal 100 is in a locked state, the first function may be a function of switching the display unit 151, which is the inactive state 350a, to the active state 350b, have.

On the other hand, when performing a predetermined function based on at least two drag taps applied at different points in time, the controller 180 can perform different functions according to the direction in which the drag touch is performed.

For example, as a condition for performing the first function, the first function may be set to "when the first drag touch moves three times in the first direction, the first drag touch is released and the second drag touch Occurrence of two vibrations upon movement in the second direction ". The second dragging touch is released three times when the first drag touch moves in the first direction, the first drag touch is released, and the second drag touch is again performed within the reference time, Quot; and " occurrence of two vibrations when moving in the direction ".

In this case, the controller 180 performs different functions according to the direction in which the first and second drag taps are applied, even if the number of vibrations generated during the application of the first and second drag taps is the same .

The first direction in which the first drag touch is applied and the second direction in which the second drag touch is applied may be different directions or the first and second drag taps may be applied at different points of time, Do.

As described above, the number of vibration times set for each function, the direction in which the drag touch is applied, and the number of points at which the drag touch starts can be variously set based on a user's request.

Hereinafter, a method for controlling the generation of vibration during the drag-touch operation will be described in detail with reference to the accompanying drawings.

7A and 7B are conceptual diagrams for explaining a method of controlling vibration generation based on a drag touch applied to the display unit.

The control unit 180 may generate at least one vibration while the dragging touch is applied to the display unit 151. [ At this time, the vibration generated while the drag touch is applied may be generated every time the drag touch passes the preset distance.

The control unit 180 generates the vibration 320 when the touch applied to the display unit 151 is moved by a predetermined distance while the touch applied to the display unit 151 is maintained After the touch is continuously moved by the predetermined distance, the vibration 320 may be generated again.

On the other hand, the controller 180 can control the distance at which the vibration is generated according to the direction in which the drag touch is applied. Specifically, the predetermined distance at which the vibration 320 is generated may vary based on a direction in which the drag touch is applied.

7A, when the dragging touch 700 is applied to the display unit 151 in the first direction 700a, the controller 180 determines that the dragging touch 700 is at the first distance (for example, It is possible to generate the vibration 320 every time it passes. On the other hand, if the dragging touch 700 is applied in the second direction 700b different from the first direction 700a, the controller 180 determines that the dragging touch 700 is in a state other than the first distance 720a The vibration 320 may be generated every time the second distance 720b is elapsed.

Although not shown, the controller 180 may control the predetermined distance at which the vibration is generated according to the number of points at which dragging starts. For example, when a drag touch is started at any one point, the controller 180 generates the vibration 320 every time the first distance elapses, and when the drag touch is started at at least two points, The vibration 320 can be generated every time the second distance different from the distance elapses.

In addition, the controller 180 may control the preset distance at which the vibration 320 is generated based on the area (area size) of the drag touch.

On the other hand, the controller 180 can generate the vibration based on the elapse of a predetermined time, rather than generating the vibration when the predetermined distance elapses, even if the drag touch is applied. That is, the controller 180 may generate the vibration 320 at a predetermined time interval while the drag touch is applied.

In this case, even if the dragging touch is applied in the same direction, the controller 180 can generate the vibration 320 every time a different distance elapses according to the speed at which the dragging is applied.

As shown in FIG. 7B, the control unit 180 can generate the vibration so as to have a constant time interval 730 when the drag touches 710a and 710b are applied.

At this time, when the drag touch 710a having the first speed is applied, the controller 180 can generate the vibration 320 at the predetermined time interval 730. [ In this case, it can be understood that the vibration 320 generated by the drag touch 710a having the first velocity is generated every time the first distance 720c has elapsed. The first distance 720c may be calculated using the time interval 730 and the first velocity.

Meanwhile, the controller 180 may generate the vibration 320 at the predetermined time interval 730 even if the drag touch 710b having the second speed higher than the first speed is applied. In this case, the vibration 320 generated by the drag touch 710b having the second speed faster than the first speed is generated every time the second distance 720d shorter than the first distance 720c is elapsed ≪ / RTI > Similarly, the second distance 720d may be calculated using the time interval 730 and the second velocity.

In other words, the control unit 180 can generate the vibration 320 at different distance intervals 720c and 720d according to the speed of the drag touch, even if the dragging touch is applied in the same direction by the same distance 720. [

With this configuration, it is possible to control various vibration generation based on the direction of the drag touch, the number of points at which the drag touch is started, the interval of the vibration generation time, and the like, and thus the security can be further enhanced.

Hereinafter, when vibration is generated based on a touch or a drag touch applied to the display unit according to an exemplary embodiment of the present invention, various functions are performed based on at least one of the generated vibration frequency and the direction in which the drag touch is performed Will be described in more detail with reference to the accompanying drawings.

FIGS. 8A and 8B are conceptual diagrams for explaining a method of performing different functions based on the number of points at which a touch is held, and FIGS. 9A, 9B, 9C, A concept diagram for explaining how to perform different functions.

The controller 180 may perform different functions based on the number of points at which the touch is held when the touch is maintained in a state where the touch is applied to at least one point.

Specifically, when the number of vibrations generated while the touch is maintained at one point on the display unit 151 and the number of vibrations generated while the touch is maintained at at least two points are the same, And performs a second function different from the first function when the touch is maintained at the at least two points.

For example, as shown in FIG. 8A, in the locked state, when a touch 810a applied to one point is held, the control unit 180 may generate at least one vibration 320 . Thereafter, when the touch 810a applied to the one point is released, the control unit 180 determines whether the touch 810a is held based on at least one vibration 320 (for example, 3 times) Thereby releasing the locked state and outputting the home screen page, as shown in the second drawing of Fig. 8A.

 On the other hand, when the touches 810b and 810c applied to at least two points are held in the locked state, as shown in the first drawing of Fig. 8B, the control unit 180 can generate at least one vibration 320 have. When the touches 810b and 810c applied to the at least two points are released, the control unit 180 controls the at least one vibration 320 (e.g., 3 (3)) generated while the touches 810b and 810c are held (For example, a web application) 800c, as shown in the second drawing of Fig.

As described above, when dragging is applied, the controller 180 may perform different functions depending on the number of points at which dragging starts. For example, when the dragging started at one point is released after a predetermined number of vibrations are generated while the dragging started from one point is applied in one direction, the controller 180 can perform the first function. On the other hand, if the drag touch that is simultaneously started at the at least two points after the predetermined number of vibrations occur while the drag touch simultaneously started in at least two points is applied in the one direction, the controller 180 controls the first function The second function can be performed.

On the other hand, the controller 180 may perform different functions depending on the position of a region (point) to which a touch is applied.

For example, at least two areas 900a, 900b, 900c, and 900d may be divided and set in the display unit 151, as shown in the first drawing of FIG. 9A. If the touch unit 910c is released after the touch unit 910c is held in one of the at least two areas 900a, 900b, 900c and 900d, (E.g., releasing the locked state and outputting the home screen page) based on the number of vibrations generated while the touch screen 910c is held and the area where the touch 910c is applied .

As another example, the control unit 180 may determine whether or not the area 900d is different from any one of the at least two areas 900a, 900b, 900c, and 900d, as shown in the first diagram of FIG. 9B. When the touch 910d is released after the touch 910d is maintained, the number of vibrations generated while the touch 910d is maintained and the number of vibrations generated while the touch 910d is applied are different from the first function And perform a second function (for example, a function of releasing the lock state and executing a predetermined application).

Similarly, when dragging is applied, the controller 180 may perform different functions according to the area where the dragging is started, and the contents described with reference to FIGS. 9A and 9B may be analogously applied.

Furthermore, the control unit 180 determines whether or not the number of times of vibration (the number of times of vibration generated while the drag touch is performed), the position of the area where the touch is maintained (the position of the area where the drag touch is started) At least one of the number of points (areas) where the touch is maintained (the number of points (areas) where the drag touch starts) and the direction in which the drag touch is applied in the case of the drag touch And the condition (combination condition) for performing the function (s) that can be performed in the mobile terminal can be variously set by the user.

On the other hand, in the locked state, more specifically, the display unit 151 may display a screen 800a corresponding to the locked state as shown in the first diagram of FIG. 9C, The corresponding screen 800a may output at least two graphic objects 930a and 930b that guide a point (area) to which a touch is to be applied (guiding the point (area) where the drag touch starts). The at least two graphic objects 930a and 930b may have different shapes (shapes), different sizes, or different colors.

Thereafter, the controller 180 may perform different functions according to a graphic object (a graphic object in which the dragging starts) among the at least two graphical objects.

For example, as shown in FIG. 9C, when vibration is generated by the drag touch 920a starting from the first graphic object 930a of the at least two graphic objects 930a and 930b, The control unit 180 determines whether or not the graphic object 930a in which the drag touch 920a starts, the number of vibrations generated while the drag touch 920a is applied, and the direction in which the drag touch 920a is applied satisfy predetermined conditions The screen 800a corresponding to the locked state can be switched to the home screen page 800b.

9D, a drag touch 920b in the second graphic object 930b, which is different from the first graphic object 930a among the at least two graphic objects 930a and 930b, The number of vibrations generated while the drag touch 930b is applied and the direction in which the drag touch 930b is applied are the same as the drag touch 930a shown in FIG. . For example, in this case, the control unit 180 may output notification information 940 indicating that the release of the locked state has failed.

10 is a conceptual view for explaining a method of performing a predetermined function based on a drag touch on the display unit in a state where a cover is mounted on the mobile terminal.

10, the present invention can be provided with a cover 800 covering or accommodating at least one surface of the mobile terminal 100. As shown in FIG. The cover 800 may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100.

The cover 800 may be mounted to cover the mobile terminal 100. In addition, the control unit 180 can activate or deactivate the display unit 151 according to whether the cover 800 is opened or closed. In addition, the control unit 180 can output predetermined screen information through the window provided in the cover 800 (the detailed description of the cover 800 will be omitted).

The control unit 180 controls the display unit 151 to display a touch (or a touch) that is applied to the display unit 151 exposed to the outside through the window provided in the cover 800, in a state that the cover 800 covers at least a part of the display unit 151 Drag touch).

The control unit 180 may generate at least one vibration while the touch is maintained and may perform a predetermined function based on the number of vibrations generated while the touch is held when the touch is released.

The controller 180 generates at least one vibration while the drag touch is being performed. When the drag touch is released, the control unit 180 generates a vibration based on the number of vibrations generated during the drag touch and the direction The set function can be performed.

In the present invention, it is possible to apply the same or similar analogy to the contents described in Figs. 2 to 9D even in the state where the cover 800 is provided.

For example, in a state in which the cover 800 is mounted and the display unit 151 is in the inactive state 1010a, as shown in the first drawing of Fig. 10, the control unit 180 controls the first drag When the touch 1000a is applied, the vibration 320 can be generated every time the first drag touch 1000a passes the preset distance.

10, the first dragging touch 1000a is released, and the second dragging touch 1000b, which is applied in the counterclockwise direction within the reference time, is canceled The vibration 320 can be generated every time the predetermined distance is elapsed while the drag touch 1000b is applied in the counterclockwise direction.

Thereafter, the control unit 180 determines whether or not the direction in which the first dragging is applied, the number of vibrations generated during the first dragging touch, the direction in which the second dragging is applied, and the direction in which the second dragging is applied (E.g., a function of switching the display unit 151, which is the inactive state 1010a, to the active state 1010b) based on the number of times of vibration that has been performed. Likewise, in the locked state, the control unit 180 determines whether or not the drag operation is performed based on the direction in which the drag touch (first and second drag touches) is applied and the number of vibrations generated while the drag touch (first and second drag touches) The function of switching the display unit in the inactive state to the active state and the function of releasing the locked state can be performed at once.

In the above description, the function of switching the display unit, which is in a disabled state, to the active state among the functions executable in the mobile terminal, the function of releasing the locked state, and the function of executing the predetermined application have been described. However, the present invention is not limited to this, and it is possible to apply analogous or similar functions to any function as long as the function is executable in the mobile terminal.

The predetermined functions, the specific functions, the first and second functions, and the like described above can be applied to any of the functions executable in the mobile terminal. Here, the predetermined function and the specific function are functions related to the number of vibrations generated while the touch is maintained or a function associated with the direction in which the drag touch is applied and the number of vibrations generated while the drag touch is applied It is to be clearly understood that the first and second functions perform different functions and are not limited to a particular function.

As described above, the present invention can generate vibration while the touch is maintained, and perform a specific function based on the number of times the vibration is generated. Therefore, the present invention can provide a new user interface capable of executing a desired function based on the number of vibrations generated while the touch is applied.

Further, the present invention can release the lock state based on the number of vibrations generated while the touch is maintained. Therefore, the present invention can provide a more security-enhanced user interface by releasing the lock state using non-visual vibration.

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.
