Abstract

A method for performing a predefined function on a touch-based mobile device includes displaying a lock-screen image on the touch screen of the mobile device during a locked-state, wherein the lock-screen image comprises a plurality of image pieces; detecting an object on or near the touch screen at a first predefined location corresponding to a predefined image piece of the plurality of image pieces; moving the predefined image piece on the touch screen according to movement of the object; and performing a predefined function on the mobile device when the predefined image piece moves from the first predefined location to a second predefined location on the touch screen.

Claims

1. A method for controlling a mobile device with a touch screen, comprising:

displaying a lock-screen image on the touch screen of the mobile device during a locked-state, wherein the lock-screen image comprises a plurality of image pieces;

detecting an object on or near the touch screen at a first predefined location corresponding to a predefined image piece of the plurality of image pieces at an initial position;

moving the predefined image piece on the touch screen according to movement of the object; and

performing a predefined function on the mobile device when the predefined image piece moves from the first predefined location to a second predefined location on the touch screen.

2. The method of claim 1, wherein the predefined function comprises unlocking the mobile device.

3. The method of claim 1, wherein the plurality of image pieces are a plurality of rectangular image pieces.

4. The method of claim 1, wherein the lock-screen image comprises no visual prompt for unlocking the mobile device.

5. The method of claim 1, further comprising:

in response to detecting that the object is no longer on or near the touch screen, moving the predefined image piece back to the initial position.

6. The method of claim 1, wherein the predefined function comprises displaying information on the lock-screen image during the locked-state.

7. The method of claim 1, wherein the predefined function comprises modifying one or more settings of the mobile device during the locked-state.

8. The method of claim 1, wherein the first predefined location and the second predefined location are user-defined.

9. A non-transitory computer-readable medium embodying a program executable in a computing device, the program comprising:

code for displaying a lock-screen image on a touch screen of the computing device during a locked-state, wherein the lock-screen image comprises a plurality of image pieces at an initial position;

code for detecting an object on or near the touch screen at a first predefined location corresponding to a predefined image piece of the plurality of image pieces;

code for moving the predefined image piece on the touch screen according to movement of the object; and

code for performing a predefined function on the computing device when the predefined image piece moves from the first predefined location to a second predefined location on the touch screen.

10. The non-transitory computer-readable medium of claim 9, wherein the predefined function comprises unlocking the mobile device.

11. The non-transitory computer-readable medium of claim 9, wherein the plurality of image pieces are a plurality of rectangular image pieces.

12. The non-transitory computer-readable medium of claim 9, wherein the lock-screen image comprises no visual prompt for unlocking the mobile device.

13. The non-transitory computer-readable medium of claim 9, wherein the program further comprises:

code for, in response to detecting that the object is no longer on or near the touch screen, moving the predefined image piece back to the initial position.

14. The non-transitory computer-readable medium of claim 9, wherein the predefined function comprises displaying information on the lock-screen image during the locked-state.

15. The non-transitory computer-readable medium of claim 9, wherein the predefined function comprises modifying one or more settings of the mobile device during the locked-state.

16. The non-transitory computer-readable medium of claim 9, wherein the first predefined location and the second predefined location are user-defined.

17. A touch-based mobile device, comprising:

a touch screen, for receiving touch control and displaying data;

one or more processors; and

a storage unit, for storing a program code executed by the one or more processors to perform the following steps;

displaying a lock-screen image on the touch screen during a locked-state, wherein the lock-screen image comprises a plurality of image pieces;

detecting an object on or near the touch screen at a first predefined location corresponding to a predefined image piece of the plurality of image pieces at an initial position;

moving the predefined image piece on the touch screen according to movement of the object; and

performing a predefined function on the mobile device when the predefined image piece moves from the first predefined location to a second predefined location on the touch screen.

18. The mobile device of claim 17, wherein the predefined function comprises unlocking the mobile device.

19. The mobile device of claim 17, wherein the plurality of image pieces are a plurality of rectangular image pieces.

20. The mobile device of claim 17, wherein the lock-screen image comprises no visual prompt for unlocking the mobile device.

21. The mobile device of claim 17, wherein the program code is executed by the one or more processors to further perform:

in response to detecting that the object is no longer on or near the touch screen, moving the predefined image piece back to the initial position.

22. The mobile device of claim 17, wherein the predefined function comprises displaying information on the lock-screen image during the locked-state.

23. The mobile device of claim 17, wherein the predefined function comprises modifying one or more settings of the mobile device during the locked-state.

24. The mobile device of claim 17, wherein the first predefined location and the second predefined location are user-defined.
