Abstract

Devices, methods, and computer-readable media process to distinguish user input device gestures, such as gestures input via a pen in a pen-based computing system, e.g., to quickly and reliably distinguish between electronic ink entry, single taps, double taps, press-and-hold actions, dragging operations, and the like. The devices, methods, and computer-readable media process quickly and reliably distinguishes between input device gestures by utilizing a gesture profile that includes a preferential input type, e.g. to preferentially recognize a received input as a first input type over a second input type.

Claims

1. A device comprising:

a processor; and

a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising;

running an application program;

rendering at least a portion of an input panel associated with the application program, wherein the input panel comprises a gesture profile, the gesture profile comprising at least one of a preferential expected input gesture type and a non-preferential expected input gesture type, wherein the preferential expected input gesture type is assigned as a more likely input type that the non-preferential expected input gesture type; and

changing a gesture recognition parameter for the non-preferential expected input gesture type based on the preferential expected input gesture type being the more likely input type for the portion of the input panel.

2. The device of claim 1, wherein the gesture recognition parameter preferentially recognizes a received input as a first input type over an excluded second input type.

3. The device of claim 2, wherein the gesture profile comprises a preference for a tap input over an excluded electronic ink input.

4. The device of claim 2, wherein the gesture profile comprises a preference for a tap input over an excluded dragging operation input.

5. The device of claim 2, wherein the gesture profile comprises a preference for a tap input over an excluded press-and-hold operation input.

6. The device of claim 2, wherein the gesture profile comprises a preference for a single tap input directed toward two separate input panel portions over a double tap input directed toward a single input panel portion.

7. The device of claim 2, wherein the gesture profile comprises a preference for a press-and-hold operation input over an excluded electronic ink input.

8. The device of claim 2, wherein the gesture profile comprises a preference for electronic ink input over an excluded tap input.

9. The device of claim 2, wherein the gesture profile comprises a preference for a press-and-hold operation input over an excluded dragging operation input.

10. The device of claim 1, wherein the gesture profile further comprises a non-preferential expected input gesture type.

11. The device of claim 1, wherein:

the gesture recognition parameter does not recognize the excluded input gesture type and recognizes the preferential expected input gesture type over the non-preferential expected input gesture type.

12. The device of claim 1, wherein said gesture recognition parameter comprises a time for an input device to be touching the portion of the input panel.

13. The device of claim 12, wherein the time is increased from an initial time value to a second time for registering the non-preferential gesture input type.

14. A method, comprising:

running an application program on a computing device;

rendering at least a portion of an input panel associated with the application program, wherein the input panel comprises a gesture profile, the gesture profile comprising both a preferential expected input gesture type and a non-preferential expected input gesture type, wherein the preferential expected input gesture type is assigned as a more likely input type than the non-preferential expected input gesture type; and

changing a gesture recognition parameter for the non-preferential expected input gesture type based on the preferential expected input gesture type being the more likely input type for the portion of the input panel.

15. The method of claim 14, wherein the gesture recognition parameter comprises a number of touches that are detected.

16. The method of claim 14, wherein the gesture recognition parameter comprises a time that a peripheral device is in contact with the portion of an input panel.

17. The method of claim 16, wherein said changing the gesture recognition parameter comprises changing the time associated with detection of the non-preferential gesture input type.

18. The method of claim 14, wherein the input panel further comprises a first input portion and a second input portion.

19. The method of claim 18, wherein each of the first and second input portions comprises a corresponding gesture profile with the preferential expected input gesture type.

20. One or more computer memory devices embodied with executable instructions that, when executed by a computing device, cause said computing device to perform operations comprising:

running an application program;

rendering at least a portion of an input panel associated with the application program, wherein the input panel comprises a gesture profile, the gesture profile comprising both a preferential expected input gesture type and a non-preferential expected input gesture type;

setting a gesture recognition parameter based at least on the gesture profile, wherein the gesture recognition parameter preferentially recognizes a received input as the preferential expected input gesture type over the non-preferential input gesture type; and

changing a gesture recognition parameter for the non-preferential expected input gesture type based on the preferential expected input gesture type being the more likely input type for the portion of the input panel.
