Abstract

There is described a portable electronic device capable of detecting wake conditions comprising a motion sensor, a touch sensor and a processor. The motion sensor is configured to detect tap data associated with user input within a predetermined time period. The touch sensor is configured to detect touch data associated with the user input within the predetermined time period. The touch sensor is activated in response to detecting the tap data at the motion sensor. The processor is configured to determine whether the touch data corresponds to at least one touch criterion, and activate a function of the portable electronic device in response to determining that the touch data corresponds to the at least one touch criterion.

Claims

1. A method of a portable electronic device for detecting wake conditions, the portable electronic device including a motion sensor and a touch sensor, the method comprising:

detecting, at the motion sensor, tap data associated with user input within a predetermined time period;

activating the touch sensor in response to detecting the tap data at the motion sensor;

detecting, at the touch sensor, touch data associated with the user input within the predetermined time period;

determining whether the touch data corresponds to at least one touch criterion; and

activating a function of the portable electronic device in response to determining that the touch data corresponds to the at least one touch criterion.

2. The method of claim 1, wherein detecting touch data associated with the user input within the predetermined time period includes detecting the touch data at the touch sensor subsequent to detecting the tap data at the motion sensor within the predetermined time period.

3. The method of claim 1, wherein determining whether the touch data corresponds to at least one touch criterion includes determining, at a processor, whether the touch data corresponds to the at least one touch criterion stored at a memory of the portable electronic device.

4. The method of claim 1, further comprising determining, at a processor, whether the tap data correspond to at least one tap criterion stored at the memory of the portable electronic device.

5. The method of claim 1, wherein the at least one touch criterion is a continuous contact at a fixed location of the touch sensor exceeding a threshold time period.

6. The method of claim 1, wherein the at least one touch criterion is a linear swipe, the linear swipe having a substantially linear form in its entirety.

7. The method of claim 1, wherein the at least one touch criterion is a non-linear gesture, the non-linear gesture having at least one part that is non-linear from at least one other part of the gesture.

8. The method of claim 1, wherein activating a function of the portable electronic device includes waking a display from a sleep state.

9. A portable electronic device capable of detecting wake conditions comprising:

a motion sensor configured to detect tap data associated with user input within a predetermined time period;

a touch sensor configured to detect touch data associated with the user input within the predetermined time period;

a processor configured to determine whether the touch data corresponds to at least one touch criterion, and activate a function of the portable electronic device in response to determining that the touch data corresponds to the at least one touch criterion.

10. The method of claim 9, the touch sensor detects the touch data subsequent to the motion sensor detecting the tap data within the predetermined time period.

11. The method of claim 9, further comprising a memory of the portable electronic device configured to store the at least one touch criterion.

12. The method of claim 9, further comprising a memory of the portable electronic device configured to store at least one tap criterion, wherein the processor determines whether the tap data correspond to the at least one tap criterion.

13. The method of claim 9, wherein the at least one touch criterion is a continuous contact at a fixed location of the touch sensor exceeding a threshold time period.

14. The method of claim 9, wherein the at least one touch criterion is a linear swipe, the linear swipe having a substantially linear form in its entirety.

15. The method of claim 9, wherein the at least one touch criterion is a non-linear gesture, the non-linear gesture having at least one part that is non-linear from at least one other part of the gesture.

16. The method of claim 9, further comprising a display, wherein the function of the portable electronic device includes waking the display from a sleep state.
