The motion recognition unit 161 determines whether the mobile terminal 100 is performing an appropriate tilting operation state, a waving operation, a snap operation, and a catching operation based on the sensor signal transmitted from the sensor detection unit 140 . The motion recognition unit 161 collects the sensor signals transmitted from the sensor detection unit 140 and discriminates whether the collected sensor signals are a forward or backward inclined motion, 165). The operation recognition unit 161 identifies whether the sensor signal transmitted from the sensor detection unit 140 is a wiggling operation or a snap operation or catching operation and transmits the operation signal to the function execution unit 165 . More specifically, the motion recognition unit 161 can check whether the amplitude variation of the frequency due to the tilting motion, the wiggling motion, and the snap motion transmitted from the sensor detection unit 140 satisfies the set period and the set amplitude, The direction of the pressure due to the holding operation, the intensity of the pressure, and the time at which the pressure is maintained can be checked to see whether the predetermined condition is satisfied. For example, the motion recognition unit 161 detects the frequency parameter values according to the tilting motion, the wiggling motion, and the snap motion according to the direction of the axis, Set the frequency parameter value. At this time, it is preferable that the motion recognition unit 161 can set the error rate for a predetermined time to 1 second or more, and the value for the absolute value can also be changed according to the intention of the designer or the reset of the user. It is preferable that the motion recognition unit 161 has a setting of having a forward tilting action or a backward tilting action according to the direction of the axis. The operation recognition unit 161 transmits the tilted operation signal, the wiggly operation signal, the snap operation signal, and the like based on the recognized tilts, shakes, and the like to the function execution unit 165.

That is, the function performing unit 165 may perform a sound alarm such as a zoom operation sound or perform a vibration alarm when the continuous operation is generated. In addition, the function performing unit 165 may control the different functions in the same terminal function according to the aspect of the tilting operation signal transmitted from the operation recognizing unit 161.

Similarly, the function execution unit 165 can check whether a touch event, a wiggling operation signal, a snap operation signal, and a catch operation signal are generated, and whether the application is applied to a currently active application program through the function table. When the operation signals described above are defined in the function table, the function execution unit 165 can control the application program operation by applying the touch event and the operation signal to the application program. At this time, as described above, the function execution unit 165 can load the function table at the time when the touch event occurs and can check whether the currently active application program has a definition for the operation according to the composite signal, It is possible to wait for a preset time to receive the operation signal after the touch event. If there is a definition of applying the composite signal according to the generation of the touch event after the catching operation signal is generated after confirming the function table, the function performing unit 165 performs the application program control which is currently activated according to the definition . Herein, the function execution unit 165 controls the operation of the application program of the portable terminal according to the generation of the touch event and the operation signal. However, the function execution unit 165 may be configured to execute the other input event, that is, The application program operation control of the portable terminal may be performed according to the generation of the pressure event and the generation of the operation signal.

In step 401, the control unit 160 controls the display unit 151 to display a screen requiring a zoom-in or zoom-out by a user's selection.

After the screen is displayed, the control unit 160 recognizes whether the user touches the touch unit 153 in step 403, and sets a point at which the user's touch is recognized as a reference point of the screen control in step 405.

Next, in step 407, the controller 160 recognizes the motion by applying a physical force to the portable terminal and recognizing whether a tilting motion signal is generated by a tilting motion having a predetermined direction and a predetermined angle. At this time, when the forward tilting operation signal is generated as in step 409, the controller 160 sequentially zooms in the display screen based on the set reference point and displays the zoomed screen in step 411. On the other hand. When the backward tilting operation signal is generated as in step 409, the controller 160 sequentially performs step 412 of zooming out the displayed screen based on the set reference point, according to the degree of tilting.

At this time, in step 411 or 412, it is possible to output a zoom operation sound or a notification vibration indicating that the zoom operation (zoom in / zoom out) is being performed.

Next, in step 413, when the controller 160 detects that the user's touch is released, the controller 160 stops the screen zooming or zooming operation by tilting, and displays the zoomed-in or zoom-out screen on the display unit 151 as in step 415 .

Referring to FIG. 5, the portable terminal can boot using the supplied power and output a predetermined idle screen. At this time, the portable terminal loads the function table and controls the application program operation corresponding to the idle screen according to the input signal. On the other hand, in the state that the standby screen is displayed, the user of the portable terminal can touch a certain area of the standby screen by holding the portable terminal with his right hand as in the screen 51. [ Then, the portable terminal can confirm whether the right grip operation performed by the user is a valid catch operation. In more detail, the portable terminal detects the direction of the pressure generated by the right hand, the intensity of the pressure, the duration of the pressure, and the like. The portable terminal can confirm whether the detected direction of the pressure, the intensity of the pressure, and the pressure duration satisfy predetermined values. When the detected values satisfy predetermined conditions, the portable terminal can recognize that the catching operation signal has occurred. The portable terminal can recognize the occurrence of the touch event in the state where the catching operation signal is generated using the touch sensor. That is, the portable terminal can recognize that a touch event occurs at the same time when a catch operation signal is generated, or that a touch event occurs within a predetermined time after the catch operation signal occurs, as a signal occurrence.

[ Here, the menu screen may be various mobile terminal functions such as a camera function and MP3 function corresponding to a file playback function as an example of an application program. In the above description, the touch event is generated while the catch operation signal is generated first. However, the catch operation signal may be generated after the touch event is generated first. That is, when the user touches the display unit while holding the portable terminal, the portable terminal loads the function table and recognizes the catching operation signal that occurs later according to the composite signal processing defined in the currently executed standby screen application program .

Meanwhile, the user of the portable terminal can hold the portable terminal with the left hand as in the 55 screen, and then can perform the touch operation on the standby screen. The portable terminal detects the direction, intensity, duration, and the like of the pressure generated corresponding to the operation performed by the user, thereby recognizing the left grip. Also, the portable terminal can recognize a touch event occurring in the display unit. Accordingly, the portable terminal loads the function table, and can output the message creation window as in the 57 screen, for example, according to the left hand operation signal and the application program control according to the touch event, according to the information defined in the function table. At this time, the portable terminal can output a key map for composing a message under the message creation window.

As described above, the portable terminal according to the present invention can recognize a grip operation signal as various operation signals according to a direction, thereby providing more various input methods. That is, the portable terminal of the present invention may have different user functions of the activated portable terminal according to the area where the catch operation signal is generated. In the above description, it is described that the touch event is generated after the catching operation. However, the catching motion recognition may be performed after the touch event has occurred. In addition, the portable terminal may recognize different input methods of generating a catching operation signal after the occurrence of a touch event and generating a touch event after generating a catching operation signal, thereby controlling the application program control differently.

In addition, the portable terminal may perform different application program control according to the area of the touch event generated in the display unit. In more detail, after a user applies a pressure to the body of the portable terminal to generate a catching operation signal, a predetermined position of the display unit, for example, a central upper end region, a central region, a lower lower end region, The mobile terminal can change the types of application programs to be activated according to various point touches and can differently control the operation of currently activated application programs. That is, the portable terminal can generate different gripping operation signals according to the direction, intensity, and holding time of the gripping operation signal, and can generate different input signals according to the point of occurrence of the touch event recognized as the composite signal. Accordingly, the portable terminal generates a large number of input signals according to the catching operation and the touch event point, and can control application program operation accordingly.

When the touch event occurs during the execution of the MP3 function, the portable terminal loads the function table, and controls a specific function of the MP3, for example, a shuffle function according to a shake motion signal generated thereafter. That is, the portable terminal displays a list of "101, 099, 102, 103" in the order from the top to the bottom of the screen from the 71 screen. After the touch event and wiggling operation signals are generated, Quot ;, ",,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,. Here, the item "I-101" is an item which is touched by the user, and the item touched by the user is excluded from the shuffle function and can be controlled to be outputted to the display unit by applying a certain rule or random shuffle function based on other items have.

Meanwhile, the portable terminal can distinguish the shaking motion signal having the amplitude and frequency of several times and the snap operation signal having the amplitude and frequency of one time, respectively, for the shaking motion of the terminal, and can perform the MP3 function differently according to each operation signal. That is, the portable terminal can support the shuffle function by mixing only items displayed on the display unit according to a certain rule when a snap operation signal is generated. When the wiggling operation signal is generated, the portable terminal can control the shuffle function to perform the shuffle function on the items displayed on the display unit and all files existing in the same folder stored in the storage unit.

Here, the mobile terminal may perform a deletion function in addition to the shuffle function for items other than the item in which the touch event occurs. That is, when the portable terminal user touches and selects specific items output on the display unit and generates a wiggle operation signal, the untouched items can be removed from the display unit.

Such a mobile terminal can perform application control differently according to a point touched by a user. That is, when the user performs a shaking operation after touching each corner of the display unit or while touching each corner of the display unit, the mobile terminal performs a shuffle function of the items currently displayed on the display unit according to the area of the corner where the touch occurs, Can be performed.

As described above, the portable terminal according to the embodiment of the present invention supports various functions of a specific application program according to a point where a touch event occurs and a wiggly operation signal or a snap operation signal.
