Abstract

A device, such as a communication device or data processing device, is configured to transition between a locked and unlocked state in response to a detected action that is interpreted as a continuous or single action. In an embodiment a first input is detected at a first input mechanism of the device when the device is locked, then a second input is detected at the second input. If the inputs are determined to be continuous, for example if the second input is detected within a predetermined period after completion of the first input, the device is unlocked. The input may also be combined or interpreted as a password or security code. Conversely, if a detected action is interpreted as a continuous or single action by an unlocked device, the device may enter the locked state in response to the detected action. Methods for implementing this transition between locked and unlocked states are also provided.

Claims

1. A method, comprising:

detecting a single, continuous unlock action applied to at least two input mechanisms on a locked electronic device; and

unlocking the electronic device in response to said detecting.

2. The method of claim 1, wherein the at least two input mechanisms are selected from the group consisting of:

a button, a keyboard, a touchpad, an optical joystick, a scroll wheel, a touchscreen, and a slider mechanism.

3. The method of claim 2, wherein the at least two input mechanisms are selected from different members of said group.

4. The method of claim 1, wherein the single, continuous unlock action is applied to two input mechanisms.

5. The method of claim 1, wherein the single, continuous unlock action is applied to three input mechanisms.

6. The method of claim 1, wherein detecting said single, continuous unlock action comprises determining that inputs applied to said at least two input mechanisms constitute a single action based on a timing or a speed of the detected inputs.

7. The method of claim 1, wherein detecting said single, continuous unlock action comprises determining that a duration of time between a detected first input at a first one of said at least two input mechanisms and a detected second input at a second one of said at least two input mechanisms is within an expected range.

8. The method of claim 1, wherein detecting said single, continuous unlock action comprises determining that a path represented by inputs applied to said at least two input mechanisms was completed within either a predefined range of speed or a predefined range of time.

9. A method, comprising:

detecting a single, continuous lock action applied to at least two input mechanisms on a locked electronic device; and

locking the electronic device in response to said detecting.

10. The method of claim 9, wherein the at least two input mechanisms are selected from the group consisting of:

a button, a keyboard, a touchpad, an optical joystick, a scroll wheel, a touchscreen, and a slider mechanism.

11. The method of claim 10, wherein the at least two input mechanisms are selected from different members of said group.

12. The method of claim 9, wherein detecting said single, continuous lock action comprises determining that inputs applied to said at least two input mechanisms constitute a single action based on a timing or a speed of the detected inputs.

13. The method of claim 9, wherein detecting said single, continuous lock action comprises determining that a duration of time between a detected first input at a first one of said at least two input mechanisms and a detected second input at a second one of said at least two input mechanisms is within an expected range.

14. The method of claim 9, wherein detecting said single, continuous lock action comprises determining that a path represented by inputs applied to said at least two input mechanisms was completed within either a predefined range of speed or a predefined range of time.

15. A method, comprising:

detecting a first input at a first input mechanism in a locked electronic device;

detecting a second input at a second input mechanism in the electronic device;

when the second input is detected within a predetermined period of time after completion of the first input, unlocking the electronic device.

16. The method of claim 15, wherein sufficient power is provided to the first input mechanism such that the first input mechanism is capable of detecting the first input.

17. The method of claim 16, wherein upon detection of the first input at the first input mechanism, the second input mechanism is activated such that the second input mechanism is capable of detecting the second input.

18. The method of claim 15, wherein the second input mechanism is a touchscreen, and the electronic device is configured to further interpret the second input as a password for user authentication.

19. The method of claim 15, wherein the first input mechanism is a button.

20. A computer program product comprising a non-transitory computer-readable medium bearing code which, when executed by an electronic device, causes the electronic device to carry out the method of:

detecting, while the electronic device is in one of a locked and unlocked state, detect a single, continuous lock action applied to at least two input mechanisms of the electronic device; and

in response to said detecting, transitioning the electronic device to the other one of the locked and unlocked state.
