Abstract

A method for unlocking an electronic device, a first touch point and a second touch point are received on an obverse touch panel and a reverse touch panel of the electronic device. The method determines a first area and a second area based on the first touch point, the second touch point and a preset size, records a duration time of an overlapping status of the first area and the second area, and unlocks the electronic device when the duration time reaches a preset value.

Claims

1. A computer-implemented method for unlocking an electronic device comprising a processor, an obverse touch panel, and a reverse touch panel, the method comprising:

determining a first touch point on the obverse touch panel and a second touch point on the reverse touch panel of the electronic device in response to receiving a first slide operation on the obverse touch panel and a second slide operation on the reverse touch panel;

determining a first area based on the first touch point and a preset size, and determining a second area based on the second touch point and the preset size;

recording a duration time of an overlapping status of the first area and the second area; and

unlocking the electronic device when the duration time reaches a preset value.

2. The method according to claim 1, wherein the first area is determined as a first circle having a preset radius, and the second area is determined as a second circle having the preset radius, a center of the first circle being the first touch point, and a center of the second circle being the second touch point.

3. The method according to claim 2, wherein the preset radius is determined according to a resolution or a sensitivity of the obverse touch panel or the reverse touch panel.

4. The method according to claim 1, wherein the first area is determined as a first rectangle having a preset width and a preset height, and the second area is determined as a second rectangle having the preset width and the preset height, a center of the first rectangle being the first touch point, and a center of the second rectangle being the second touch point.

5. The method according to claim 1, wherein the first area overlaps with the second area upon the condition that the first area and the second area have at least one intersection point.

6. An electronic device, comprising:

an obverse touch panel;

a reverse touch panel;

a storage device;

at least one processor; and

one or more modules that are stored in the storage device and are executed by the at least one processor, the one or more modules comprising;

a signal receiving module that determines a first touch point on the obverse touch panel and a second touch point on the reverse touch panel in response to receiving a first slide operation on the obverse touch panel and a second slide operation on the reverse touch panel;

a calculating module that determines a first area based on the first touch point and a preset size, and determines a second area based on the second touch point and the preset size;

a time recording module that records a duration time of an overlapping status of the first area and the second area; and

an unlocking module that unlocks the electronic device when the duration time reaches a preset value.

7. The electronic device according to claim 6, wherein the first area is determined as a first circle having a preset radius, and the second area is determined as a second circle having the preset radius, a center of the first circle being the first touch point, a center of the second circle being the second touch point.

8. The electronic device according to claim 7, wherein the preset radius is determined according to a resolution or a sensitivity of the obverse touch panel or the reverse touch panel.

9. The electronic device according to claim 6, wherein the first area is determined as a first rectangle having a preset width and a preset height, and the second area is determined as a second rectangle having the preset width and the preset height, a center of the first rectangle being the first touch point, and a center of the second rectangle being the second touch point.

10. The electronic device according to claim 6, wherein the first area overlaps with the second area upon the condition that the first area and the second area have at least one intersection point.

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

determining a first touch point on an obverse touch panel and a second touch point on a reverse touch panel of the electronic device in response to receiving a first slide operation on the obverse touch panel and a second slide operation on the reverse touch panel;

determining a first area based on the first touch point and a preset size, and determining a second area based on the second touch point and the preset size;

recording a duration time of an overlapping status of the first area and the second area; and

unlocking the electronic device when the duration time reaches a preset value.

12. The non-transitory storage medium according to claim 11, wherein the first area is determined as a first circle having a preset radius, and the second area is determined as a second circle having the preset radius, a center of the first circle being the first touch point, and a center of the second circle being the second touch point.

13. The non-transitory storage medium according to claim 12, wherein the preset radius is determined according to a resolution or a sensitivity of the obverse touch panel or the reverse touch panel.

14. The non-transitory storage medium according to claim 11, wherein the first area is determined as a first rectangle having a preset width and a preset height, and the second area is determined as a second rectangle having the preset width and the preset height, a center of the first rectangle being the first touch point, a center of the second rectangle being the second touch point.

15. The non-transitory storage medium according to claim 11, wherein the first area overlaps with the second area upon the condition that the first area and the second area have at least one intersection point.

16. The non-transitory storage medium according to claim 11, wherein the medium is selected from the group consisting of a hard disk drive, a compact disc, a digital video disc, and a tape drive.
