Abstract

An unlocking method for an electronic device which has a plurality of light-sensors thereon and stores an application program therein first executes the application program when the electronic device works in a locking mode. When the application program is executed, the method continually computes a covering order of user'"'"'s covering action performed on the light-sensors via the application program. Therefore, the method controls the electronic device to switch from the locking mode to an unlocking mode when the covering order of the covering action is matched with an unlocking condition.

Claims

1. An unlocking method for electronic device used on an electronic device, the electronic device including a plurality of light-sensors thereon, and the unlocking method comprising:

a) accepting external covering action by the light-sensors;

b) determining whether a covered order of the covering action on the light-sensors is matched with an unlocking condition or not; and

c) switching the electronic device from a locking mode to an unlocking mode when the covered order is matched with the unlocking condition.

2. The unlocking method of claim 1, wherein the electronic device includes a memory therein, and the memory stores the unlocking condition, the locking mode, the unlocking mode, and an application program, and the application program determines whether the covered order is matched with the unlocking condition or not in step b.

3. The unlocking method of claim 2, further includes the following steps of:

d) determining whether a covered time of the covering action is matched with the unlocking condition or not; and

e) switching the electronic device from the locking mode to the unlocking mode when the covered time is matched with the unlocking condition.

4. The unlocking method of claim 2, further includes the following steps before step a:

a01) activating the application program; and

a02) activating the light-sensors.

5. The unlocking method of claim 4, wherein the electronic device includes a control button thereon, and the application program and the light-sensors are activated when the electronic device works in the locking mode and the control button is pressed in step a01 and step a02.

6. The unlocking method of claim 4, wherein the electronic device includes a display monitor thereon, and a step a03 is further included before step a:

displaying backlight via the display monitor.

7. The unlocking method of claim 6, wherein a step a04 is further included before step a:

displaying instruction information according to an unlocking action via the display monitor.

8. The unlocking method of claim 6, wherein the light-sensors are set in parallel under the display monitor, and the unlocking condition is matched when the light-sensors are covered in order of left to right direction in step c.

9. The unlocking method of claim 6, wherein the light-sensors are set in vertical and at left side of the display monitor, and the unlocking condition is matched when the light-sensors are covered in order of bottom to top direction in step c.

10. The unlocking method of claim 6, wherein the light-sensors are set in vertical and at right side of the display monitor, and the unlocking condition is matched when the light-sensors are covered in order of bottom to top direction in step c.
