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 an electronic device, comprising:

a) activating a plurality of light-sensors;

b) covering the plurality of light-sensors in a predetermined order, wherein the light-sensors are determined to be covered when not detecting light source;

c) determining whether the predetermined order of covering the light-sensors is matched with an unlocking condition or not; and

d) switching the electronic device from a locking mode to an unlocking mode when the predetermined 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 predetermined order is matched with the unlocking condition or not in step c.

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

d) determining whether a covered time of covering the plurality of light-sensors 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 a step of activating an application program before step b.

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.

6. The unlocking method of claim 4, wherein the electronic device includes a display which is not a touch screen, and a step a03 is further included before step b:

displaying backlight via the display.

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

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

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