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 a first parameter with a first threshold that varies as a function of a second threshold of a second parameter, such that the first threshold increases when the second threshold increases and the first threshold decreases when the second threshold decreases, and

at least a second gesture defined by a third parameter with a third threshold that varies as a function of a fourth threshold of a fourth parameter, such that the third threshold decreases when the fourth threshold increases and the third threshold increases when the fourth threshold decreases; and

causing an operation to be performed that corresponds to the determined gesture.

2. The method as described in claim 1, wherein the second parameter is time.

3. The method as described in claim 2, wherein the first parameter is distance or pressure.

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

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

6. 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.

7. The method as described in claim 1, further comprising adjusting the first and second thresholds.

8. The method as described in claim 7, wherein the adjusting is performed based on observed interaction with the computing device.

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

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

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

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

the computing device determining which of a plurality of gestures correspond to the input based at least in part on the plurality of parameters, wherein the plurality of gestures include;

at least a first gesture defined by a first parameter with a first threshold that varies as a function of a second threshold of a second parameter, such that the first threshold increases when the second threshold increases and the first threshold decreases when the second threshold decreases, and

at least a second gesture defined by a third parameter with a third threshold that varies as a function of a fourth threshold of a fourth parameter, such that the third threshold decreases when the fourth threshold increases and the third threshold increases when the fourth threshold decreases.

12. The method as described in claim 11, further comprising causing an operation to be performed by the computing device that corresponds to the determined gesture.

13. The method as described in claim 11, wherein the at least the second gesture includes a pan gesture and the at least the first gesture includes a tap gesture.

14. The method as described in claim 11, wherein the second parameter and the fourth parameter both comprise time.

15. The method as described in claim 11, wherein the first parameter is distance or pressure.

16. The method of claim 11, wherein the second threshold varies as an exponential function of the first parameter.

17. One or more computer-readable memories comprising instructions that are executable by a computing device to determine which determined gesture of a plurality of gestures corresponds to an input detected using touchscreen functionality of the computing device and to apply an operation based on the determined gesture, the determination of the determined gesture being based at least in part by a differentiation made between the plurality of gestures relative to detected parameters of the input, wherein the plurality of gestures includes:

at least a first gesture defined by a first parameter with a first threshold that varies as a function of a second threshold of a second parameter, such that the first threshold increases when the second threshold increases and the first threshold decreases when the second threshold decreases, and

at least a second gesture defined by a third parameter with a third threshold that varies as a function of a fourth threshold of a fourth parameter, such that the third threshold decreases when the fourth threshold increases and the third threshold increases when the fourth threshold decreases.

18. One or more computer-readable memories as described in claim 17, further comprising causing an operation to be performed that corresponds to the determined gesture.

19. One or more computer-readable memories as described in claim 17, wherein the first parameter is distance.

20. One or more computer-readable memories as described in claim 17, wherein the threshold for the distance is defined to vary inversely with respect to the different parameter.

21. One or more computer-readable memories as described in claim 17, wherein the second gesture is a pan gesture and the first gesture is a tap gesture.
