Abstract

Techniques involving gestures and other functionality are described. In one or more implementations, an input is recognized by a computing device as corresponding to a gesture, the gesture defined using a plurality of parameters, at least one of which having a threshold that varies with respect to another one of the parameters. An operation is caused to be performed by the computing device that corresponds to the gesture.

Claims

1. A method implemented by a computing device, the method comprising:

detecting, by the computing device, an input comprising a plurality of parameters;

determining which gesture of a plurality of gestures the input corresponds to based at least in part on the plurality of parameters, wherein the plurality of gestures include at least a first gesture defined by either distance or pressure with a first threshold that varies as a function of a second threshold of time, such that the first threshold automatically increases when the second threshold increases and the first threshold automatically decreases when the second threshold decreases;

causing an operation to be performed that corresponds to the determined gesture; and

adjusting at least the first threshold or the second threshold in response to observed interactions, including the input, with the computing device.

2. The method as described in claim 1, wherein the input is a touch input detected using touchscreen functionality of the computing device.

3. The method as described in claim 1, further comprising detecting the input using a camera.

4. The method as described in claim 1, further comprising outputting a result of the operation by the computing device for display by a display device.

5. The method as described in claim 1, wherein the first and second thresholds are set to filter jitter from a touch point, and wherein the adjusting includes automatically increasing the first threshold to be higher in response to detecting an increase in the second threshold comprising a period of time in which a user finger remains stationary.

6. The method of claim 1, wherein the plurality of gestures include a pan gesture and wherein the first gesture is a tap gesture.

7. The method of claim 1, wherein the second threshold varies as an exponential function of the first parameter.

8. The method of claim 1, wherein the second threshold varies as a linear function of the first parameter.

20. The method of claim 1, wherein adjusting at least the first threshold or the second threshold occurs in response to observed user-corrective interactions including monitoring gesture corrections made by a user when an unintended gesture is initiated.

9. A computing device comprising:

a touch sensitive display;

one or more processors; and

one or more storage media having stored computer-executable instructions for implementing a method for managing gesture thresholds, the method comprising;

detecting, by the computing device, an input at the touch sensitive display comprising a plurality of parameters;

determining which gesture of a plurality of gestures the input corresponds to based at least in part on the plurality of parameters, wherein the plurality of gestures include at least a first gesture defined by either distance or pressure with a first threshold that varies as a function of a second threshold of time, such that the first threshold automatically increases when the second threshold increases and the first threshold automatically decreases when the second threshold decreases;

causing an operation to be performed that corresponds to the determined gesture; and

adjusting at least the first threshold or the second threshold in response to observed interactions, including the input, with the computing device.

10. The computing device as described in claim 9, the method further comprising detecting the input using a camera.

11. The computing device as described in claim 9, the method further comprising outputting a result of the operation by the computing device for display by a display device.

12. The computing device as described in claim 9, wherein the first and second thresholds are set to filter jitter from a touch point, and wherein the adjusting includes increasing the first threshold to be higher in response to detecting an increase in the second threshold comprising a period of time in which a user finger remains stationary.

13. The computing device as described in claim 9, wherein the plurality of gestures include a pan gesture and wherein the first gesture is a tap gesture.

14. The computing device as described in claim 9, wherein the second threshold varies as an exponential function of the first parameter.

15. The computing device as described in claim 9, wherein the second threshold varies as a linear function of the first parameter.

21. The computing device as described in claim 9, wherein the input is a touch input detected using touchscreen functionality of the computing device.

16. One or more computer-readable memories comprising instructions that are executable by a computing device to implement a method for managing gesture parameters, the method including:

detecting, by the computing device, an input at a touch sensitive display of the computing device, the input comprising a plurality of parameters;

determining which gesture of a plurality of gestures the input corresponds to based at least in part on the plurality of parameters, wherein the plurality of gestures include at least a first gesture defined by either distance or pressure with a first threshold that varies as a function of a second threshold of time, such that the first threshold automatically increases when the second threshold increases and the first threshold automatically decreases when the second threshold decreases;

causing an operation to be performed that corresponds to the determined gesture; and

adjusting at least the first threshold or the second threshold in response to observed interactions, including the input, with the computing device.

17. The computing device as described in claim 16, wherein the input is a touch input detected using touchscreen functionality of the computing device.

18. The computing device as described in claim 16, the method further comprising detecting the input using a camera.

19. The computing device as described in claim 16, wherein the first and second thresholds are set to filter jitter from a touch point, and wherein the adjusting includes increasing the first threshold to be higher in response to detecting an increase in the second threshold comprising a period of time in which a user finger remains stationary.
