Abstract

A method for processing a touch signal in a mobile terminal and a mobile terminal using the same are disclosed, wherein the method comprises: detecting a shaking of a mobile terminal by using a mobile terminal shaking detection sensor within a predetermined time from a touched time while a touch screen is being touched; and outputting an output signal based on the detected shaking.

Claims

1. A method for processing a user input in a mobile terminal, the method comprising:

displaying data on a touch screen of the mobile terminal;

receiving a touch input on a portion of the data on the touch screen;

detecting movement of the mobile terminal while the touch input on the portion of the data is maintained;

changing a size of the data based on an area where the touch input is received in response to the movement of the mobile terminal; and

displaying the size-changed data on the touch screen.

2. The method of claim 1, further comprising determining an intensity of the touch input on the portion of the data on the touch screen.

3. The method of claim 2, further comprising performing a function based on the intensity of the touch input when the intensity of the touch input is greater than a predetermined threshold.

4. The method of claim 1, further comprising:

displaying a page-down or page-up icon on the touch screen;

receiving a touch input on the page-down or page-up icon;

determining an intensity of the touch input; and

displaying the data scrolled-down or scrolled-up based on the intensity of the touch input on the page-down or page-up icon.

5. The method of claim 1, wherein:

the movement of the mobile terminal includes a movement upward; and

changing the size of the data comprises enlarging the size of the data.

6. The method of claim 1, wherein:

the movement of the mobile terminal includes a movement downward; and

changing the size of the data comprises reducing the size of the data.

7. The method of claim 1, wherein changing the size of the data comprises changing the size of the data corresponding to a position where the touch input is received.

8. The method of claim 7, wherein changing the size of the data further comprises changing a size of a first portion of the data corresponding to a specific area around the position where the touch input is received while maintaining a size of a second portion of the data that doesn'"'"'t correspond to the specific area.

9. The method of claim 7, wherein changing the size of the data further comprises changing a size of a first portion of the data inside a specific area around the position where the touch input is received while maintaining a size of all other data displayed on the touch screen.

10. A mobile terminal for processing a user input, the terminal comprising:

a touch screen configured to receive a touch input and display data;

a movement detection sensor configured to detect movement of the mobile terminal; and

a controller configured to

receive a touch input on a potion of the data on the touch screen;

change a size of the data based on an area where the touch input is received when the movement detection sensor detects the movement of the mobile terminal while the touch input on the portion of the data is maintained, and

control the touch screen to display the size-changed data.

11. The mobile terminal of claim 10, wherein the controller is further configured to determine an intensity of the touch input on the portion of the data on the touch screen.

12. The mobile terminal of claim 11, wherein the controller is further configured to perform a function based on the intensity of the touch input when the intensity of the touch input is greater than a predetermined threshold.

13. The mobile terminal of claim 10, wherein the controller is further configured to:

control the touch screen to display a page-down or page-up icon;

receive a touch input on the page-down or page-up icon;

determine an intensity of the touch input; and

control the touch screen to display the data scrolled-down or scrolled-up based on the intensity of the touch input on the page-down or page-up icon.

14. The mobile terminal of claim 10, wherein:

the movement of the mobile terminal includes a movement upward; and

the controller further configured to enlarge the size of the data based on the area where the touch input is received.

15. The mobile terminal of claim 10, wherein:

the movement of the mobile terminal includes a movement downward; and

the controller is further configured to reduce the size of the data based on the area where the touch input is received.

16. The mobile terminal of claim 10, wherein the controller is further configured to change the size of the data corresponding to a position where the touch input is received.

17. The mobile terminal of claim 16, wherein the controller is further configured to change the size of a first portion of the data corresponding to a specific area around the position where the touch input is received while maintaining a size of a second portion of the data that does not correspond to the specific area.

18. The mobile terminal of claim 16, wherein the controller is further configured to change the size of the data inside a specific area around the position where the touch input is received while maintaining a size of all other data displayed on the touch screen.
