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.

Meanwhile, in the present invention, information processed in the mobile terminal can be displayed using a flexible display. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a conceptual diagram for explaining another example of the mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting unit may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, a battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 due to an external force, taking into account the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

The display unit 151 of the mobile terminal 100 according to the present invention may have a main display region exposed on the front face of the mobile terminal 100 and at least one secondary display region exposed on the side face of the mobile terminal 100 have.

3 is a diagram showing an example of a mobile terminal 100 having a main display area and a secondary display area. 3 (a), the main display 151-1 is a display area exposed on the front surface of the mobile terminal 100, and the auxiliary display 151-2 is a display area exposed on the front surface of the mobile terminal 100, And may mean a display area exposed to the side surface. 3 (b) is a perspective view of the mobile terminal 100. As shown in Fig.

The main display 151-1 and the auxiliary display 151-2 may be implemented through separate electronic components, respectively. Alternatively, in the case where the display unit 151 is a flexible display capable of bending freely, at least one end of the flexible display is bent so that the main display 151-1 and the auxiliary display 151-2 ) May be formed.

In the example shown in FIG. 3, the auxiliary display 151-2 is provided on both the left and right sides of the mobile terminal 100, but may be provided only on one of the left and right sides.

In an embodiment of the present invention, an indicator area occupied in a partial area of the main display 151-1 is moved to the secondary display 151-2 so as to secure a wider screen on the main display 151-1 We propose a control method.

4 is a diagram illustrating a tapping input received on the back side of a mobile terminal, in accordance with an embodiment of the present invention.

In one embodiment of the present invention, a tapping (tapping) input 400 on the back side of the mobile terminal is sensed and a mobile terminal is controlled based on the sensed tapping input 400. Hereinafter, in the description of the embodiments of the present invention, a tapping input to the back side of the mobile terminal will be referred to as a back tap input 400. [

4 (a) shows a backtap input 400 received via the user's hand 403.

According to one embodiment of the present invention, the back-tap input 400 may be sensed using at least one of an acceleration sensor, a gravity sensor, and a gyroscope sensor of the sensing unit 140. For example, when the back-tap input 400 is received, the controller 180 may determine that a back-tap input has been received when sensing a change in acceleration in a specific direction received from the acceleration sensor.

According to another embodiment of the present invention, the backtap input 400 may be detected using a backtap detection sensor additionally provided on the back surface of the mobile terminal 100. [ The back tap detection sensor may include a piezoelectric sensor, a touch sensor, or the like for detecting a user's tapping.

Embodiments of the present invention are not limited to methods for sensing backtap input 400 and various sensing methods for sensing backtap input will be applicable to embodiments of the present invention.

Furthermore, in one embodiment of the present invention, the left back tap input, the right back tap input, and the central back tap input may be classified according to the position at which the back tap input 400 is received. 4B, the controller 180 receives a backtap input received on the left side 402a of the back side of the mobile terminal as a left backtap input, a backtap input received in the center area 402b as a center backtap input, 402c may be classified as a right backtap input.

In an embodiment of the present invention, in order to classify the types of the back taps, a method of firstly comparing the absolute values of the temporal changes of the acceleration relative to each other may be used. For example, if the right backtap input is received when the ratio of absolute values of x, y, and z axis acceleration variations is a: b: c when a left backtap input is received, if the ratio is d: e: f So that the back-tap input can be distinguished.

That is, the control unit 180 stores a template signal (reference signal for use in comparison) for each backtap input, and when receiving a backtap input, a backtap input for the most similar template signal among the template signals is applied .

Further, the control unit 180 may distinguish between the back-tapped gestures using correlation information between the sensing signal received from the gyroscope sensor and the sensing signal received from the accelerometer.

In addition, in the embodiment of the present invention, a back tap input with a left hand and a back tap input with a right hand are distinguished as well as a tapping input to a left side 402a, a center region 402b, and a right side 402c .

According to an embodiment of the present invention, this distinction can be distinguished by using the direction and / or the shape of the change of the acceleration received through the acceleration sensor. The left side 402a, the center area 402b and the right side 402c using the left hand and the left side 402a, the center area 402b and the right side 402c using the right hand, The tapping input to be input to each will be distinguished.

According to another embodiment of the present invention, it is proposed to classify the left / right-handed tapping input by classifying the gripping state of the left / right hand based on the touch input received through the auxiliary display 151-2. A specific method will be described with reference to Fig.

FIG. 5 illustrates a control method of distinguishing the left-hand / right-handed grip state based on a touch input received on the auxiliary display 151-2, according to an embodiment of the present invention.

Referring to FIG. 5A, the user holds the mobile terminal 100 using the right hand 403R. 5B shows a touch input received through the auxiliary display 151-2 in a state in which the mobile terminal 100 is held using the right hand 403R.

If the user is naturally holding the mobile terminal 100, the left auxiliary display 151-2L may be touched 501b by a stop, a ring finger, and the like. The right auxiliary display 151-2R will be touch 501a by thumb or touch 501c by palm.

Accordingly, the controller 180 can distinguish whether the hand holding the mobile terminal 100 is a left hand or a right hand based on the type of touch input received through the auxiliary display 151-2.

In particular, the touch 501c by the palm will be easy to specify since it is received over a relatively large area when compared with the touches 501a and 501b by the other finger. That is, when the width of the touch input received through the auxiliary display 151-2 is equal to or larger than a predetermined width, the controller 180 can determine that the touch is the touch 501c by the palm.

In addition, when judging the touch 501c by the palm, the touch at the upper end of the touch 501c by the palm can be identified as the touch 501a by the thumb. Alternatively, the touch input closest to the touch 501c by the palm can be identified as the touch 501a by the thumb.

Meanwhile, in one embodiment of the present invention to be described later, a control method of identifying a touch 501a by the thumb and providing a UI (User Interface) around the position of the touch 501a by the identified thumb I will explain.

In the following detailed description referring to the drawings and drawings, a control method based on input of the detected back taps (including classification for left / center / right and left / right hands) will be described in detail.

In particular, a control method for easily accessing a predetermined function in a locked state of the touch screen 151 will be described in the embodiment described below with reference to the drawings. Generally, the touch screen 151 is a lock mode, which is set to prevent malfunction or can not be touched until it is released for security of the mobile terminal 100 itself, Lock screen). If the predetermined unlocking condition is satisfied, the mobile terminal 100 may be released from the lock mode, and the predetermined unlocking condition may be a condition for inputting the pattern / code encrypted by the user. That is, when the predetermined unlocking condition is satisfied, the mobile terminal 100 can be controlled. However, in the embodiment of the present invention, a method of easily accessing a predetermined function without satisfying the unlocking condition is proposed.

6 is a flowchart illustrating a control method of outputting a function icon based on a touch position of a thumb according to the detection of a back-tap input according to an embodiment of the present invention. 7 is a diagram showing a state diagram of a control method of outputting a function icon based on a touch position by a thumb according to the detection of a back-tap input according to an embodiment of the present invention. 6 and Fig. 7 together. Fig.

In step S601, the control unit 180 enters the lock mode of the touch screen 151 (see Fig. 7 (a)). In this case, the touch screen 151 may be divided into a main display 151-1 area and a sub display area 151-2.

In step S602, the controller 180 determines whether the unlock condition for the lock mode of the touch screen 151 is satisfied. If the unlock condition is satisfied, the controller 180 proceeds to step S603 to release the lock mode of the touch screen 151 And terminates. If the lock release condition is not satisfied, the process can proceed to step S604.

In step S604, the control unit 180 may detect a tapping input (back-tap input) received on the back surface of the mobile terminal 100. [ If it is determined that the tapping input is received, the control unit 180 proceeds to step S605. Otherwise, the control unit 180 may return to step S601.

In step S605, the control unit 180 may output at least one function icon 701a, 701b, and 701c around the position 501a where the thumb touches. In this case, the position 501a at which the thumb touches may be identified using the method described above with reference to FIG.

That is, according to the above-described flowchart, the user can easily access a predetermined function without releasing the lock mode for the touch screen 151. For example, when the user of the mobile terminal 100 enters the back tab in a state where the lock mode is set, the phone icon 701a, the text message check icon 701b, and the search icon 701c are displayed around the user ' And the desired function can be easily executed by using the output function icons. The function icons may be icons preset by the user or may be automatically selected by the control unit 180.

In the above-described embodiment, function icons that can be output in the lock mode have been described. 8, an embodiment of the present invention will be described using an example of a function icon that can be output when the lock mode of the mobile terminal 100 is released.

8 is a diagram showing a control method of outputting a function icon based on a back-tap input received in a state in which a lock mode is released, according to an embodiment of the present invention.

Referring to FIG. 8 (a), the mobile terminal 100 outputs an execution screen 801 of a predetermined application in a state in which the lock mode is released.

The controller 180 may output the first to third function icons 802 to 804 on the touch screen 151. The first to third function icons 802 to 804 Is selected and touched, the function corresponding to the selected function icon can be executed.

The first function icon 802 is a function icon for canceling (canceling) the most recently executed user command. That is, when the first function icon 802 is received, the control unit 180 can cancel the most recently performed function corresponding to the user's command.

The second function icon 803 is a function icon for outputting a home screen.

I will elaborate further on the home screen.

In general, the home screen may be defined as a screen displayed on the touch screen 151 for the first time when the lock state of the touch screen 151 is released, and may include one or more icons for executing an application or an internal function, The widget may be displayed. In this case, when a predetermined touch gesture is performed on the touch screen 151, the two or more home screens may be sequentially displayed one by one. Other icons (widgets) may be placed in each of the home screens.

Therefore, when receiving the input that the second function icon 802 is selected, the control unit 180 stops the execution screen of the application being output, and outputs the home screen have. On the other hand, if the input to select the second function icon 802 is received during the output of the home screen, the controller 180 may not perform any operation.

The third function icon 804 is a function icon for outputting a menu list. Upon receiving the selection of the third function icon, the control unit 180 outputs a predetermined menu list to select a menu item from the user.

The first to third function icons 802 to 804 are function icons that are frequently used in controlling the mobile terminal 100. The function icons may be generally displayed on the touch screen 151 in some areas or may be provided as hardware buttons have.

In an embodiment of the present invention, when a back-tap input is received, it is proposed to output a function icon menu 800 including at least one function icon near the touch 501a by thumb (see Fig. 8 (b) ). 8 (b), the function icon menu 800 may be output as a fan shape around the touch position 501a by the thumb, and the first to third function icons 802, 804).

That is, the output function icons are outputted near the position of the thumb, so that the user can easily perform the functions using the thumb.

In order to execute the function icon on the function icon menu 800 shown in FIG. 8 (b), a touch input may be required for the function icon to be executed. The function icon menu 800 is displayed close to the position of the thumb, but it is not easy to easily execute all of the function icons included. That is, the function icon (802, 803 function icon in the illustrated example) at the top of the function icon menu 800 can be easily touched by using the thumb, but the function icon (804, 805 function icon) Touching can be inconvenient.

Accordingly, in an embodiment of the present invention, the icon deactivation area 808 is set on the function icon menu 800 and the function icon selected on the deactivation area 808 is not executed. 8B, the first and second function icons 802 and 803 of the first to fourth function icons 802 to 805 displayed on the function icon menu 800 are displayed in the inactive area 808 And the third and fourth function icons 804 and 805 are present in the inactive area 808. [ When the input in which the first and second function icons 802 and 803 are selected is received, the controller 180 can execute a function corresponding to the selected function icon. However, when the third and fourth function icons 804 and 805 receive the selected input, the control unit 180 does not execute the function corresponding to the selected function icon.

If the user wants to execute the function icon included in the inactive area 808, the function icon must be moved out of the inactive area 808 through the scrolling operation on the sector icon icon 800. After the third and fourth function icons 804 and 805 are moved out of the inactive area 808 through the scroll operation, when the control unit 180 receives an input from which one of the function icons is selected, It may perform a function corresponding to the icon.

Further, the function icon (s) 802 to 804 may be output on the secondary display 151-2, as described above in Fig. 7 (see Fig. 8 (c)). In this case, the function icon (s) 802 to 804 can be outputted around the position of the touch 501a by the thumb. When one of the function icon (s) 802 to 804 receives an input to be selected, the controller 180 can perform a function corresponding to the selected function icon.

Hereinafter, another control method for executing the function icon on the function icon menu 800 will be described with reference to FIG.

9 is a view for explaining a method of executing the function icon menu 800 according to an embodiment of the present invention.

In the embodiment of FIG. 9, the execution of the function icon menu 800 is not performed by touching each function icon. In this embodiment, it is proposed to output the selection indicator 901 and scroll the function icon to the position of the selection indicator 901 to execute it.

Referring to FIG. 9A, the function icon menu 800 includes a plurality of function icons 802 to 805. The plurality of function icons may be scrolled based on the touch input 10a of the user, and additional function icons 806 and 807 may be further output by scrolling.

The user's touch input 10a for scrolling movement may be an input for dragging in a direction to scroll while touching one point of the function icon menu 800. [

The controller 180 scrolls by the touch input 10a of the user and when the touch is released, the controller 180 can execute a position icon (or corresponding to the selection indicator) on the selection indicator 901 . 9 (b), when the touch input 10a of the user is released while the third function icon 804 is positioned inside the selection indicator 901 by the scroll movement, The control unit 180 can execute a function corresponding to the third function icon 804 (see Fig. 9 (c)).

On the other hand, as shown in FIG. 8C, when the function icons are not arranged in a fan shape, it is obvious that the function icons can be executed through the touch input without selecting by the selection indicator 901.

In the embodiment described above with reference to Figs. 6 and 7, a control method corresponding to one back tap input received on the lock screen has been described. A control method corresponding to back-tack input for a plurality of solutions will be described below with reference to Fig.

10 is a diagram illustrating a control method of switching widgets when an additional backtap input is received, in accordance with an embodiment of the present invention.

Referring to Fig. 10 (a), there is shown a state diagram in which at least one function icon 701a to 701c is displayed on the lock screen. The at least one function icon may be a function icon output in response to receiving a backtap input on a lock screen as in the control method described above with reference to Fig. The first widget 1001-1 is output on the lock screen.

When an additional backtap input is detected, the controller 180 can switch the first widget 1001-1 to the second widget 1001-2 (see FIG. 10 (b)). Likewise, in the lock screen state in which the second widget 1001-2 is output, the control unit 180 can switch to the third widget 1001-3 in response to detection of an additional backtap input c). If an additional backtap input is detected in a state where the third widget 1001-3 is displayed, if there is no other widget to be output, the user can return to the first widget 1001-1 which is the original widget.

Meanwhile, the embodiment of the present invention is also possible in a state in which the mobile terminal 100 operates in the landscape mode.

11 is a diagram illustrating a control method of outputting a function icon menu corresponding to a backtap input received in the landscape mode according to an embodiment of the present invention.

The output position of the function icon menu can be controlled by separating the left / right backtap input even in the landscape mode. That is, the output position of the function icon menu can be output differently by distinguishing the back-tap input received in the left area 1101a and the back-tap input received in the right area 1101b based on the center of the mobile terminal 100 .

11A, when the left back tap input is received in the landscape mode, the control unit 180 displays the function icon menu 800 in the first area (left area) of the touch screen 151, Can be output. On the other hand, when the right backtap input is received, the control unit 180 may output the function icon menu 800 in the second area (right area) of the touch screen 151.

On the other hand, in an embodiment of the present invention, it is proposed to control the release of the power and the lock mode of the display based on the back-tap input. This embodiment will be described with reference to Figs. 12 and 13. Fig.

12 and 13 are diagrams illustrating a control method for controlling power and a lock mode of a display on the basis of a back-tap input according to an embodiment of the present invention.

Fig. 12 assumes that no encrypted pattern / code is needed to release the lock mode of the touch screen 151, and Fig. 13 assumes that an encrypted pattern / code is needed.

12 (a), it is assumed that the power of the touch screen 151 of the mobile terminal 100 is off and locked. Upon receiving the double back tap input, the control unit 180 can release the lock state while powering the touch screen 151 (refer to FIG. 12 (b)). In this case, the double back-tap input may refer to a back-tap input two times in succession (input two times within a predetermined time interval). When the locked state is released, the mobile terminal 100 may output a screen or output a home screen before entering the lock mode.

Furthermore, the mobile terminal 100 proposes to further detect the state of the user holding the mobile terminal 100 through the area of the secondary display 151-2. That is, when the user inputs a double back-tap while holding the mobile terminal 100, it is proposed to release the lock mode. This is because, in the case of the back-tap input, it is difficult to distinguish from other external shocks received by the mobile terminal 100, but if it is detected that the mobile terminal 100 is held, to be.

When the triple back-tap input is received while the lock mode is released, the control unit 180 can enter the lock mode again. In this case, the triple back-tap input may mean a back-tap input three times in succession (three times within a predetermined time interval).

On the other hand, in the embodiment described with reference to FIG. 13, the unlocking pass code is set based on the left / center / right back tap input, and the lock mode is released using the set pass code.

In the example shown in FIG. 13, it is assumed that the predetermined backtap code is left -> right -> center backtap input. 13A, when the back-tap input corresponding to the predetermined back-up pass code is received while the touch screen 151 is turned off, the mobile terminal 100 turns on the power of the touch screen 151, Can be released.

The back-up cipher code is an input made on the back side of the mobile terminal 100, and thus has a high security because it is not easily exposed by other users.

The present invention described above can be implemented 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). In addition, 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.
