A text input window including a touch key is displayed (S205). A specific character may be input or a specific function may be executed by touching any one of a plurality of touch keys included in the text input window.

In the state where the text input window is displayed, the main body including the first body 100A and the second body 100B according to the change of the detection signal output from the motion sensor 145 or the like is left or right at the position where the text input window is displayed. When a movement inclined in one direction is detected (S210), the controller 180 changes the display of at least one of the plurality of touch keys included in the text input window in response to the degree of inclination of the main body (S215). .

In this case, the change of the display of the plurality of touch keys included in the text input window includes changing the display position of the touch key according to the degree of inclination of the main body, or enlarging the size of the touch key.

The display change of the plurality of touch keys is for convenience of character input even when the main body is inclined. For example, when the main body is inclined to the left, the touch keys positioned at the right boundary of the text input window may be displayed at a lower position than the touch keys positioned at the left boundary. By such a display change, an operation of inputting or editing characters using only one hand can be more conveniently performed.

5 is a flowchart provided to explain an operation control method of a portable terminal according to another embodiment of the present invention.

Referring to FIG. 5, first, a text input window is displayed on the display unit 151 according to a user's command or the like (S300). When the touch key enlargement display is selected in the state in which the text input window is displayed on the display unit 151 (S305), the controller 180 enlarges the size of the turkey displayed on the text input window, except for the predetermined touch key. The touch key is displayed on the display unit 151 (S310). That is, as the size of the touch key is enlarged, all of the touch keys included in the text input window cannot be displayed. Therefore, only the remaining touch keys are displayed while hiding the touch keys positioned at the right or left boundary of the text input window.

In such a state, the main body including the first body 100A and the second body 100B according to the change of the detection signal output from the motion sensor 145, etc. When a movement inclined in the direction is detected (S315), the controller 180 changes the touch key displayed on the display unit 151 according to the movement of the main body (S320). For example, when the main body is tilted to the right, the touch key positioned on the left boundary of the text input window is displayed and the position where the touch key is displayed moves to the right, and the touch key positioned on the right boundary of the text input vehicle disappears. Similarly, when the main body is tilted to the left side, the touch key positioned at the right boundary of the text input window is displayed and the position where the touch key is displayed moves to the left, and the touch key positioned at the left boundary of the text input window disappears.

Depending on the setting, the touch key displayed on the display unit 151 may be changed according to an input of touching and dragging the display unit 151 instead of moving the main body.
