The controller 180 may use the operation key area displayed on the screen of the touch screen to perform a function other than the operation key of the three-dimensional motion recognition function. For example, when the touch intensity of the second touch operation is within a predetermined range, the controller 180 activates the three-dimensional operation recognition function in response to the second touch operation, And performs a specific function corresponding to the second touch operation when the predetermined range is exceeded. Features of the mobile terminal 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 12 to 15. FIG.

12 is a flowchart illustrating a method of driving a mobile terminal according to another embodiment of the present invention. Hereinafter, the mobile terminal driving method will be described with reference to FIG. 1 and FIG.

When the user performs a second touch operation on the operation key region, the sensing unit 140 senses the second touch operation with respect to the operation key region and transmits the sensed result to the control unit 180 (S210). Then, the controller 180 calculates the strength of the second touch operation on the operation key area (S220).

Then, the controller 180 determines whether the touch intensity of the second touch operation is lower than a predetermined threshold strength (S230). If the touch intensity of the second touch operation is lower than the threshold intensity, the controller 180 activates the three-dimensional operation recognition function (S240). Otherwise, the controller 180 controls the second touch operation And performs a corresponding specific function (S250). That is, in the embodiment of FIG. 12, the predetermined range of the touch intensity at which the controller 180 activates the three-dimensional motion recognition function is a range in which the intensity of the second touch operation is lower than the threshold intensity.

13 is a diagram illustrating that the touch operation for the operation key region in the mobile terminal 100 according to the embodiment of the present invention may have different strengths. At this time, the controller 180 of the mobile terminal 100 can determine the touch intensity of the second touch operation based on the touch area of the touch screen according to the second touch operation with respect to the operation key area.

12, when the touch area of the touch screen according to the second touch operation is within a predetermined range, the controller 180 determines the strength of the second touch operation as a first step, If the touch area is out of the predetermined range, the intensity of the second touch operation can be determined as the second step.

At this time, if the strength of the second touch operation is the first step, the controller 180 activates the three-dimensional operation recognition function in response to the second touch operation, and if the intensity of the second touch operation is the second step, It is possible to perform a predetermined function corresponding to the second touch operation. Based on this, an example shown in Figs. 14 and 15 will be described.

FIG. 14 shows that a predetermined function is performed in response to the touch operation and the three-dimensional operation for the operation key region when the touch intensity with respect to the operation key region is within a predetermined range. That is, FIG. 14 shows an example in which, when the touch intensity with respect to the operation key region is the first step, a function corresponding to the three-dimensional operation is performed after the three-dimensional motion recognition function is activated in response to the touch operation.

Referring to FIG. 14, when the user's touch operation on the operation key region is sensed and the three-dimensional motion recognition function is activated, when the user performs a tilting operation that is a three-dimensional operation with respect to the mobile terminal 100 The control unit 180 performs a function of scrolling an album list, which is a specific function corresponding to the tilting operation, on the music playback application execution screen (FIG. 14 (b)).

FIG. 15 is a diagram showing that a specific operation corresponding to the touch operation can be performed when the touch intensity with respect to the operation key region is a predetermined range or more. That is, FIG. 15 shows an example in which a specific function corresponding to the touch operation is performed in response to the touch operation when the touch intensity with respect to the operation key region is the second step. At this time, the three-dimensional motion recognition function is not activated based on the touch operation.

Referring to FIG. 15, when the user touches the operation key region, the controller 180 determines that the user performs a function of selecting an album list, which is a specific function corresponding to the touch operation, on the music playback application execution screen (Fig. 15 (a)). At this time, it can be seen that the touch area in the operation key area in Fig. 15 is wider than the touch area in the operation key area in Fig. 14 (Fig. 15 (b)).
