Abstract

A method for unlocking screen, a mobile electronic device using the same and a storage medium thereof are disclosed. First, at least two signal input areas on a touch screen of the mobile electronic device are defined. When an input signal is detected within at least one signal input areas, a moving range of a trajectory produced by the input signal is calculated. And the touch screen is unlocked when the moving range reaches the predetermined value. Thus, the present invention provides a user with more virtual manner to close the screen locking function so as to promote the usage convenience of the mobile electronic device.

Claims

the method comprising;

defining at least two signal input areas on the touch screen;

detecting an input signal within the signal input areas, and calculating a moving range of a trajectory produced by the input signal when the input signal is detected within at least one of the signal input areas; and

unlocking the touch screen of the mobile electronic device when the moving range reaches a predetermined value.

2. The method for unlocking screen according to claim 1, wherein when the input signal is detected within at least one of the signal input areas, the step of calculating the moving range of the trajectory produced by the input signal further comprises:

respectively calculating the moving ranges of a first trajectory produced by a first input signal and a second trajectory produced by a second input signal when simultaneously detecting the first input signal and the second input signal within two of the signal input areas.

3. The method for unlocking screen according to claim 2, wherein the first trajectory and the second trajectory have an identical moving direction.

4. The method for unlocking screen according to claim 2, wherein the first trajectory and second trajectory respectively have an opposite moving direction.

5. The method for unlocking screen according to claim 2, wherein when the moving range reaches the predetermined value, the step of unlocking the touch screen of the mobile electronic device comprises:

unlocking the touch screen of the mobile electronic device when either the moving range of the first trajectory or the moving range of the second trajectory reaches the predetermined value.

6. The method for unlocking screen according to claim 2, wherein when the moving range reaches the predetermined value, the step of unlocking the touch screen of the mobile electronic device comprises:

unlocking the touch screen of the mobile electronic device when both the moving ranges of the first trajectory and the second trajectory reach the predetermined value.

7. The method for unlocking screen according to claim 1, further comprising:

displaying a default image on each of the signal input areas.

8. The method for unlocking screen according to claim 7, further comprising:

changing the default image on the corresponding signal input area when the input signal is detected within at least one of the signal input areas.

9. The method for unlocking screen according to claim 1, wherein when the moving range reaches the predetermined value, the step of unlocking the touch screen of the mobile electronic device comprises:
