Abstract

An electronic device and a method uses to unlock touch screens. A first icon is displayed on a locked touch screen. The first icon randomly moves on the touch screen. A second icon is displayed on the touch screen when the touch screen is touched. The touch screen is unlocked when the second icon is made to touch the first icon.

Claims

1. A method for unlocking touch screens being performed by execution of computerized codes by a processor of an electronic device, the method comprising:

displaying a first icon on a touch screen which is locked, and randomly generating directions and distances for the first icon to move;

controlling the first icon to move according to the directions and distances;

displaying a second icon on the touch screen when a touch takes place on the touch screen; and

unlocking the touch screen when the second icon touches the first icon.

2. The method according to claim 1, before displaying the first icon, the method further comprising:

determining whether the touch screen needs to be unlocked according to whether a waking condition of the touch screen is triggered.

3. The method according to claim 1, before displaying the second icon on the touch screen, the method further comprising:

determining whether the touch takes place during a first predetermined time period which begins at the time of the first icon being generated, to determine whether to display the second icon or not.

4. The method according to claim 1, wherein the second icon still displays on the touch screen after the touch is no longer present on the touch screen until a second predetermined time period has expired, the second predetermined time period beginning from the touch being no longer present on the touch screen.

5. The method according to claim 1, wherein the second icon disappears as soon as the touch is no longer present on the touch screen, and reappears when a new touch takes place on the touch screen during a second predetermined time period which begins from the touch being no longer present on the touch screen.

6. The method according to claim 1, wherein the first icon and the second icon are represent by pictures of objects, animals, or plants.

7. A electronic device, comprising:

a non-transitory storage medium;

at least one processing unit; and

one or more modules that are stored in the non-transitory storage medium; and

are executed by the at least one processing unit, the one or more modules comprising instructions to;

display a first icon on a touch screen which is locked, and randomly generating directions and distances for the first icon to move;

control the first icon to move according to the directions and distances;

display a second icon on the touch screen when a touch takes place on the touch screen; and

unlock the touch screen when the second icon touches the first icon.

8. The electronic device according to claim 7, further comprising a sensor that detects a trigger of a waking condition of the touch screen when the touch screen is in a sleep mode.

9. The electronic device according to claim 8, wherein the one or more modules further comprises instructions to:

determine whether the touch screen needs to be unlocked according to whether a waking condition of the touch screen is triggered.

10. The electronic device according to claim 7, wherein the one or more modules further comprises instructions to:

determine whether the touch takes place during a first predetermined time period which begins at the time of the first icon being generated, to determine whether to display the second icon.

11. The electronic device according to claim 7, wherein the second icon still displays on the touch screen after the touch is no longer present on the touch screen until a second predetermined time period has expired, the second predetermined time period beginning from the touch is no longer present on the touch screen.

12. The electronic device according to claim 7, wherein the second icon disappears as soon as the touch is no longer present on the touch screen, and reappears when a new touch takes place on the touch screen during a second predetermined time period which begins from the touch being no longer present on the touch screen.

13. The electronic device according to claim 7, wherein the first icon and the second icon are represent by pictures of objects, animals, or plants.

14. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for unlocking touch screens, wherein the method comprises:

displaying a first icon on a touch screen which is locked, and randomly generating directions and distances for the first icon to move;

controlling the first icon to move according to the directions and distances;

displaying a second icon on the touch screen when a touch takes place on the touch screen; and

unlocking the touch screen when the second icon touches the first icon.

15. The storage medium according to claim 14, before displaying the first icon, the method further comprising:

determining whether the touch screen needs to be unlocked according to whether a waking condition of the touch screen is triggered.

16. The storage medium according to claim 14, before displaying the second icon on the touch screen, the method further comprising:

determining whether the touch takes place during a first predetermined time period which begins at the time of the first icon being generated, to determine whether to display the second icon or not.

17. The storage medium according to claim 14, wherein the second icon still displays on the touch screen after the touch is no longer present on the touch screen until a second predetermined time period has expired, the second predetermined time period beginning from the touch being no longer present on the touch screen.

18. The storage medium according to claim 14, wherein the second icon disappears as soon as the touch is no longer present on the touch screen, and reappears when a new touch takes place on the touch screen during a second predetermined time period which begins from the touch being no longer present on the touch screen.

19. The storage medium according to claim 14, wherein the first icon and the second icon are represent by pictures of objects, animals, or plants.
