If there is an accelerated touch input through the display unit 151 in the state that the operation screen is displayed (S256), the controller 180 controls the first operation related to the selected operation mode to be performed (S258). If the touch input is performed through the display unit 151, the controller 180 controls the second operation related to the selected operation mode to be performed (S262).

Here, examples of the first and second operations to be performed may vary depending on the selected operation mode. For example, it is possible to display a shortcut menu or the like upon the acceleration touch input on the idle screen, and display the main menu screen upon touch input. In addition, a video call function is performed when the call key is acceleratedly touched on the idle screen, and a voice call function is performed when the call key is touched. In addition, the information displayed in the accelerated touch input and the information displayed in the touch input can be configured differently according to the selected operation mode and the like.

If there is any other user input such as an accelerated touch input or a touch input (S264), the controller 180 controls the operation corresponding to the user input to be performed (S268).

This process is repeatedly performed until the selected operation mode is terminated (S270). Also, according to the above-described process, another operation can be performed according to the accelerated touch input and the touch input.

6 is a flowchart illustrating a method of controlling a mobile terminal according to another embodiment of the present invention. Referring to FIG. 6, if there is no touch input or key input for a predetermined time, the control unit 180 controls the touch input or general key input to enter a protection state or a lock state in which no operation is performed (S300 ). If there is an accelerated touch input through the display unit 151 in such a locked state, the control unit 180 controls to enter the unlock preparation mode (S304). At this time, a tactile effect indicating the entry into the unlock preparation mode can be generated.

If there is an accelerated touch input again within a predetermined time in the lock release preparation mode, the control unit 180 controls to enter the lock release mode (S308). In this case as well, a tactile effect indicating that the lock is released can be generated.

The control unit 180 can control to enter the unlocking mode even if there is a key signal set as the unlocking state release key in addition to the continuous accelerated touch input (S310)

The lock state can be quickly released according to the continuous acceleration touch input through the display unit 151 instead of releasing the lock state according to the input of the lock release key.

FIG. 7 is a diagram for describing an accelerated touch input used in a method of controlling a portable terminal according to the present invention. As shown in FIG. 7, when the user's finger is close to the display unit 151, the proximity sensor 141 installed on the first body or the like senses it and outputs a proximity signal. At this time, when the user's finger is at the D2 position and at the D1 position, it can be configured to output different proximity signals. That is, the distance at which the detection object approaches the proximity sensor and the proximity signal is output is referred to as the detection distance Sn. When a plurality of proximity sensors having different detection distances are used and the proximity signals output from the proximity sensors are compared It is possible to know how close the object is in proximity.

The general touch input and the accelerated touch input can be recognized in the following manner by using the proximity signal thus detected and the input of the touch signal through the display unit 151. [

First, an accelerated touch input and a general touch input can be distinguished from each other according to a time difference from when a user's finger or the like is touched on the display unit 151 to a moment when a finger or the like falls on the touched surface.

That is, it can be defined as 'touch time = time when the hand is away from the touch surface - time when touching the touch surface', so that the accelerated touch input and the touch input can be distinguished by the touch time. For example, when the time is set to 40 ms, the touch time is less than 40 ms means that the touch surface is released quickly after touching. Therefore, the touch time is recognized as the accelerated touch input. Since it means that the hand is released, it can be recognized as a touch input.

Second, by using the proximity sensor, it is possible to distinguish between the accelerated touch input and the general touch input in proximity according to the proximity speed approaching the display unit after entering the proximity effective distance. If the time in the proximity of D2 is T2 and the time in the proximity of D1 is T1, the proximity acceleration speed = (D2 - D1) / (T2 - T1).

Therefore, when the reference speed is set to 40 m / s, the accelerated touch input is recognized when the proximity acceleration speed is less than 40 m / s, and the touch input is recognized when the acceleration speed is 40 m / s or more.

Third, it can be discriminated by acceleration touch input and touch input according to the degree of pressure applied to the touch surface of the display unit 151 after touch. For example, when the reference value is set to 40 kgf / cm 2, less than 40 kgf / cm 2 means that the touch surface is pressed smoothly, so that it is recognized as a touch input, and when the reference value is 40 kgf / cm 2 or more, So it can be recognized as accelerated touch input.

Such a recognition method can be used alone or in combination, and various other methods can be used.

FIG. 8 shows an example of identification criteria of accelerated touch input, touch input, and long touch input. In Fig. 8, the long touch input can be recognized when the touch time or the proximity holding time is longer than a predetermined time, or when a predetermined pressure or more is applied.

Depending on the usage environment, it is possible to control the touch signal by sensing in two steps of accelerated touch input and touch input without distinguishing the long touch input, or to distinguish the touch signal in three steps of accelerated touch input and touch input in addition to long touch input .

FIG. 9 shows a process of setting vibrations having different patterns and intensities for the accelerated touch input, the touch input, and the long touch input. As shown in FIG. 9, the user can arbitrarily set a tactile effect such as an accelerated touch input, a touch input, and a vibration that is fed back when a long touch is input, according to a user setting item in a touch form through the display unit.

In addition, after the sensing method for the touch input and the like, different tactile effects can be generated depending on the operation menu, the execution state of the operation mode, the display state, and the like, and the user can arbitrarily set the tactile effect.
