Abstract

An electronic device includes a vibration sensor. The vibration sensor senses shake of the electronic device. If the user shakes the electronic device when a screen of the electronic device is in a locked state, the electronic device detects if the vibration sensor is activated. If the vibration sensor is activated, the electronic device counts a number of activation times of the vibration sensor. If the number of the activation times of the vibration sensor is the same as a predefined number, the screen of the electronic device is unlocked.

Claims

1. An electronic device, comprising:

a storage system;

at least one processor; and

one or more programs being stored in the storage system and executable by the at least one processor, the one or more programs comprising;

a setting module that sets an initial value of an activation times of a vibration sensor of the electronic device;

a counting module that increases the activation times by one when a screen of the electronic device is in a locked state and the vibration sensor is activated; and

an opening module that unlocks the screen when a number of the activation times is the same as a predefined number.

2. The electronic device as described in claim 1, wherein the one or more programs further comprises a timing module that reads a first system time of the electronic device when the vibration sensor is activated.

3. The computing device as described in claim 2, wherein the one or more programs further comprises:

a first detecting module that calculates a difference between a second system time of the electronic device and the first system time of the electronic device, and detects if the difference is the same as a predefined value;

a second detecting module that detects if the number of the activation times equals the predefined number when the difference is the same as the predefined value, wherein the screen of the electronic device remains in the locked state when the number of the activation times is different from the predefined number;

a second sensing module that detects if the vibration sensor is further activated again when the difference is different from the predefined value; and

the counting module that further increases the activation times by one again when the vibration sensor is activated again.

4. A method being executed by a processor of a computing device for unlocking a screen of an electronic device, comprising:

setting an initial value of an activation times of a vibration sensor of the electronic device;

increasing the activation times by one when a screen of the electronic device is in a locked state and the vibration sensor is activated; and

unlocking the screen when a number of the activation times is the same as a predefined number.

5. The method as described in claim 4, after the setting step further comprising:

reading a first system time of the electronic device when the vibration sensor is activated.

6. The method as described in claim 5, further comprising:

calculating a difference between a second system time of the electronic device and the first system time of the electronic device, and detecting if the difference is the same as a predefined value;

detecting if the number of the activation times is the same as the predefined number when the difference is the same as the predefined value, and the screen of the electronic device remains in the locked state when the number of the activation times is different from the predefined times; and

detects if the vibration sensor is further activated when the difference is different from the predefined value, and increasing the activation times by one again when the vibration sensor is activated again.

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

setting an initial value of an activation times of a vibration sensor of the electronic device;

increasing the activation times by one when a screen of the electronic device is in a locked state and the vibration sensor is activated; and

unlocking the screen when a number of the activation times is the same as a predefined number.

8. The non-transitory storage medium as described in claim 7, after the setting step further comprising:

reading a first system time of the electronic device when the vibration sensor is activated.

9. The non-transitory storage medium as described in claim 8, further comprising:

calculating a difference between a second system time of the electronic device and the first system time of the electronic device, and detecting if the difference is the same as a predefined value;

detecting if the number of the activation times is the same as the predefined number when the difference is the same as the predefined value, and the screen of the electronic device remains in the locked state when the number of the activation times is different from the predefined times; and

detects if the vibration sensor is further activated when the difference is different from the predefined value, and increasing the activation times by one again when the vibration sensor is activated again.
