Abstract

Briefly, a method and apparatus for recognizing a series of touches with varying intensity or angle of descending on a touch panel interface is disclosed. The method comprises receiving user input with a touch panel interface, recognizing a series of touches with varying intensity or angle of descending on the touch panel interface, and performing an action associated with the series of touches with varying intensity or angle of descending on the touch panel interface.

Claims

1. A method, comprising:

receiving user input with a touch panel interface;

recognizing a series of touches with varying intensity or angle of descending on the touch panel interface, wherein recognizing the series of touches comprises;

receiving a series of touch instances as shapes on a touch panel displaying a keyboard;

classifying the shapes to distinguish finger from non-finger typing; and

analyzing the shapes to identify proximity clustering to avoid transient panel reading from being identified as finger typing; and

performing an action associated with the series of touches with varying intensity or angle of descending on the touch panel interface.

2. The method of claim 1, wherein the action is one of executing a system action, adding expressive features to text, and filtering to remove resting interactions.

3. The method as recited in claim 2, wherein executing a system action comprises executing a complex action which otherwise would require one of multiple user steps, a short cut action, and a macro function to execute.

4. The method of claim 2, wherein once a series of touches with varying intensity or angle of descending on the touch panel interface is recognized, it is acted upon, or negative results are reported.

5. The method of claim 2, wherein if a series of touches with varying intensity or angle of descending on the touch panel interface is not recognized, the user is prompted to associate the a series of touches with varying intensity or angle of descending on the touch panel interface with a computing event and wherein the a series of touches with varying intensity or angle of descending on the touch panel interface may be pre-defined or defined during use by the user.

6. The method of claim 1, wherein recognizing the series of touches with varying intensity or angle of descending on the touch panel interface further comprises:

identifying long panel interactions as resting interactions;

monitoring intensity of the series of touch instances to identify hover instances;

measuring movement of the touch instances; and

assigning keystroke and rest contact types to the shapes.

7. The method of claim 1, wherein the user input requires only a small and/or dynamically-allocated region of the touch panel.

8. The method of claim 1, wherein the touch panel interface is a screen associated with a handheld device, cell phone or consumer electronic device and the series of touches with varying intensity or angle of descending on the touch panel interface is input anywhere on the screen to activate a desired response.

9. An apparatus, comprising:

a touch subsystem including a touch panel for receiving user input in the form of a series of touches with varying intensity or angle of descending on the touch panel interface; and

a processing unit to;

recognize the series of touches with varying intensity or angle of descending on the touch panel interface in the user input, wherein recognizing the series of touches comprises;

receiving a series of touch instances as shapes on a touch panel displaying a keyboard;

classifying the shapes to distinguish finger from non-finger typing; and

analyzing the shapes to identify proximity clustering to avoid transient panel reading from being identified as finger typing; and

perform an action associated with the a series of touches with varying intensity or angle of descending on the touch panel interface.

10. The apparatus of claim 9, wherein the action is one of executing a system action, adding expressive features to text, and filtering to remove resting interactions.

11. The apparatus of claim 10, wherein executing a system action comprises executing a complex action which otherwise would require one of multiple user steps, a short cut action, and a macro function to execute.

12. The apparatus of claim 10, wherein once a series of touches with varying intensity or angle of descending on the touch panel interface is recognized, it is acted upon, or negative results are reported.

13. The apparatus of claim 9, wherein recognizing the series of touches with varying intensity or angle of descending on the touch panel interface further comprises:

identifying long panel interactions as resting interactions;

monitoring intensity of the series of touch instances to identify hover instances;

measuring movement of the touch instances; and

assigning keystroke and rest contact types to the shapes.

14. The apparatus of claim 9, wherein the user input requires only a small and/or dynamically-allocated region of the touch panel.

15. The apparatus of claim 9, wherein the touch panel interface is a screen associated with a handheld device, cell phone or consumer electronic device and the series of touches with varying intensity or angle of descending on the touch panel interface is input anywhere on the screen to activate a desired response.

16. The apparatus of claim 9, wherein if a series of touches with varying intensity or angle of descending on the touch panel interface is not recognized, the user is prompted to associate the a series of touches with varying intensity or angle of descending on the touch panel interface with a computing event and wherein the a series of touches with varying intensity or angle of descending on the touch panel interface may be pre-defined or defined during use by the user.

17. A non-transitory non-volatile computer readable medium encoded with computer executable instructions, which when accessed, cause a machine to perform operations comprising:
