Abstract

A function execution method and apparatus thereof for displaying one or more sub-functions included in a function selected by a first touch on a trace according to a second touch input based upon the first and the second touches inputted with a timing difference, and executing the relevant sub-function selected among the displayed one or more sub-functions. For this purpose, a function execution method according to the present invention is performed by comprising: detecting a first touch input touched on a display unit; detecting a drag created by a second touch inputted while maintaining the first touch; and displaying one or more sub-functions included in a function selected by the first touch along a trace of the detected drag on the display unit.

Claims

1. A method of controlling a mobile terminal, the method comprising:

displaying, on a touch screen of the mobile terminal, one or more function icons associated with one or more functions;

receiving a first touch input applied to a specific function icon among the one or more function icons;

receiving a second touch input applied to the touch screen along a first direction while the first touch input is maintained;

displaying, on a region corresponding to a touch trace of the second touch input, one or more sub function icons corresponding to one or more sub functions related to a specific function of the specific function icon, in response to the second touch input applied while the first touch input is maintained,

wherein the displaying of the one or more sub function icons is maintained though the first touch input and the second touch input are released such that one of the one or more sub function icons is selected by a third touch input, and

wherein the one or more sub function icons disappear from the touch screen in response to a fourth touch input applied to the touch screen along a second direction opposite to the first direction.

2. The method of claim 1, wherein the first touch input or the third touch input comprises a contact touch or a proximity touch.

3. The method of claim 1, wherein the second touch input is applied to a random position of the touch screen.

4. The method of claim 1, wherein an execution screen corresponding to the one of the one or more sub function icons is displayed in response to the third touch input.

5. The method of claim 1, wherein when the one of the one or more sub function icons displayed on the touch screen is not selected within a preset time period, an activated state of the first touch input is released.

6. The method of claim 5, wherein when the one of the one or more sub function icons displayed on the touch screen is not selected within a preset time period, the one or more sub function icons are is no longer displayed on the touch screen.

7. A mobile terminal, comprising:

a touch screen; and

a controller configured to;

display, on the touch screen of the mobile terminal, one or more function icons associated with one or more functions;

receive a first touch input applied to a specific function icon among the one or more function icons;

receive a second touch input applied to the touch screen along a first direction while the first touch input is maintained; and

display, on a region corresponding to a touch trace of the second touch input, one or more sub function icons corresponding to one or more sub functions related to a specific function of the specific function icon, in response to the second touch input applied while the first touch input is maintained,

wherein the displaying of the one or more sub function icons is maintained though the first touch input and the second touch input are released such that one of the one or more sub function icons is selected by a third touch input, and

wherein the one or more sub function icons disappear from the touch screen in response to a fourth touch input applied to the touch screen along a second direction opposite to the first direction.

8. The terminal of claim 7, wherein the first touch input or the third touch input comprises a contact touch or a proximity touch.

9. The terminal of claim 7, wherein the second touch input is applied to a random position of the touch screen.

10. The terminal of claim 7, wherein an execution screen corresponding to the one of the one or more sub function icons is displayed in response to the third touch input.

11. The terminal of claim 7, wherein when the one of the one or more sub function icons displayed on the touch screen is not selected within a preset time period, the controller is configured to release an activated state of the first touch input.

12. The terminal of claim 11, wherein when the one of the one or more sub function icons displayed on the touch screen is not selected within a preset time period, the one of the one or more sub functions are no longer displayed on the touch screen.
