Abstract

The disclosure provides an unlock method of an electronic system with a touch screen. The unlock method includes steps below: receiving a triggering event when the system is locked; activating the touch screen in response to the event; receiving an input gesture; comparing the gesture with a customized gesture; unlocking the system in case that the input gesture is matched to the customized gesture, which is customized by user, and is not a default unlock gesture built in the electronic system.

Claims

1. A method for unlocking an electronic system equipping with a touch screen, comprising:

wherein the customized gesture is customized by user of the electronic system, not a default unlock gesture built in the electronic system.

2. The method of claim 1, wherein the trigger event is generated by an apparatus chosen from any one of the followings:

a button;

the touch screen, wherein the scan period of touching is lengthened;

an acceleration sensor;

a touching apparatus other than the touch screen;

a photonic sensor; and

a camera.

3. The method of claim 1, wherein the activating step further comprise prompting user for unlock, wherein the prompt includes any combination of text, graphics, animation, and sounds, wherein the prompting step further comprise at least prompting user regarding to the customized gesture;

and

prompting user regarding to the unlock gesture.

4. The method of claim 1, wherein the customized gesture comprises at least one of the following:

an absolute trace of single finger moving on the touch screen; and

a relative trace of multiple finger moving on the touch screen,

wherein a parameter set of the customized gesture comprises any combination of the following;

dimension;

orientation;

time duration;

pressure;

error range of dimension;

error range of orientation;

error range of time duration; and

error range of pressure,

wherein the match of the input gesture and the customized gesture is based on the comparison of the parameter set.

5. The method of claim 1, wherein prior to the unlocking, the method further comprises:

prompting additional challenge;

determining whether response is met with the additional challenge;

unlocking the electronic system if the additional challenge is met with

determining whether a threshold number or a threshold time limit is exceeded if the additional challenge is not met with response; and

remaining lock of the electronic system if a threshold number or a threshold time limit is exceeded.

6. The method of claim 1, the method further comprises:

determining whether a threshold number or a threshold time limit is exceeded if the input gesture is not matched with the customized gesture; and

remaining lock of the electronic system if a threshold number or a threshold time limit is exceeded.

7. The method of claim 1, wherein after the unlocking, the method further comprises at least one of the following:

displaying desktop;

recovering screen before the electronic system is locked;

loading a first computing environment corresponding to the customized gesture of a first user, wherein the first user is logged in when the electronic system is locked; and

logging out of the first user and loading a second computing environment corresponding to the customized gesture of a second user.

8. The method of claim 1, further comprises a customization method for setup the customized gesture, wherein the customization method comprises:

receiving the customized gesture;

setting a parameter set of the customized gesture;

affirming the customized gesture according to the parameter set;

setting a corresponding computing environment and/or user account; and

simulating the method of claim 1.

9. A method for customizing a customized gesture to unlock an electronic system equipping with a touch screen, comprising:

receiving the customized gesture;

setting a parameter set of the customized gesture; and

affirming the customized gesture according to the parameter set, wherein the customized gesture is customized by user of the electronic system, not a default unlock gesture built in the electronic system.

10. The method of claim 9, further comprises:

setting a corresponding computing environment and/or user account; and

simulating an unlock method of the electronic system, wherein the unlock method comprises;

receiving a trigger event when the electronic system is locked;

activating the touch screen;

receiving an input gesture by the touch screen;

comparing the input gesture with a customized gesture; and

unlocking the electronic system if the input gesture and the customized gesture are matched.

11. A controller for an electronic system equipping with a touch screen, comprising:

a trigger event receiver module for receiving a trigger event when the electronic system is locked;

a touch screen control module for activating the touch screen and receiving an input gesture; and

a computing and control module for comparing the input gesture with a customized gesture and unlocking the electronic system if the input gesture and the customized gesture are matched,

wherein the customized gesture is customized by user of the electronic system, not a default unlock gesture built in the electronic system.

12. The controller of claim 11, wherein the controller is configured for prompting user for unlock, wherein the prompt includes any combination of text, graphics, animation, and sounds, wherein the touch screen control module is further configured to perform at least one of the following:

prompting user regarding to the customized gesture; and

prompting user regarding to the unlock gesture.

13. The controller of claim 11, wherein the customized gesture comprises at least one of the following:

an absolute trace of single finger moving on the touch screen; and

a relative trace of multiple finger moving on the touch screen,

wherein a parameter set of the customized gesture comprises any combination of the following;

dimension;

orientation;

time duration;

pressure;

error range of dimension;

error range of orientation;

error range of pressure,

wherein the match of the input gesture and the customized gesture is based on the comparison of the parameter set.

14. The controller of claim 11, wherein prior to the unlocking, the controller is further configured to perform:

prompting additional challenge;

determining whether response is met with the additional challenge;

unlocking the electronic system if the additional challenge is met with response;

determining whether a threshold number or a threshold time limit is exceeded if the additional challenge is not met with response; and

remaining lock of the electronic system if a threshold number or a threshold time limit is exceeded.

15. An electronic system, comprising:

a case;

a touch screen, encapsulated by the case; and

a controller, encapsulated by the case and coupled to the touch screen, the controller comprises;
