Abstract

A computing system includes a touch-input receptor and a touch-detection module. The touch-detection module is configured to track a touch input directed to the touch-input receptor. The computing system also includes a control module to change a parameter of the computing system indicated by an initial portion of the touch input tracked by the touch-detection module. The control module is configured to change the parameter by an amount indicated by a subsequent portion of the touch input tracked by the touch-detection module.

Claims

1. A computing system, comprising:

a touch display;

a gesture library including a shared modulate gesture and a plurality of different mode gestures, each mode gesture associated with a changeable parameter of the computing system, and the shared modulate gesture linkable with each mode gesture to indicate an amount to change the changeable parameter associated with that mode gesture;

a touch-detection module to track a touch input directed to the touch display, the touch input beginning with a source engaging the touch display and continuing until the source disengages the touch display;

a gesture-recognition module to select a selected mode gesture from the plurality of different mode gestures based on an initial portion of the touch input and to select the shared modulate gesture based on a subsequent portion of the touch input linked to the initial portion of the touch input; and

a control module to change the changeable parameter associated with the selected mode gesture by an amount indicated by the shared modulate gesture.

2. The computing system of claim 1, where the shared modulate gesture is characterized by a looping touch input.

3. The computing system of claim 2, where the control module is configured to change the changeable parameter associated with the selected mode gesture by an amount indicated by an angular measurement of the shared modulate gesture.

4. The computing system of claim 2, where the control module is configured to change the changeable parameter associated with the selected mode gesture at a rate indicated by an angular speed of the shared modulate gesture.

5. The computing system of claim 2, where the control module is configured to change the changeable parameter associated with the selected mode gesture in increments indicated by an angular speed of the shared modulate gesture.

6. The computing system of claim 2, where the control module is configured to increase the changeable parameter associated with the selected mode gesture responsive to the shared modulate gesture looping clockwise.

7. The computing system of claim 2, where the control module is configured to decrease the changeable parameter associated with the selected mode gesture responsive to the shared modulate gesture looping counterclockwise.

8. The computing system of claim 1, where one or more of the plurality of different mode gestures are multi-touch mode gestures.

9. The computing system of claim 1, where the changeable parameter associated with the selected mode gesture is a zoom level.

10. The computing system of claim 1, where the changeable parameter associated with the selected mode gesture is a volume level.

11. The computing system of claim 1, where the changeable parameter associated with the selected mode gesture is a scroll level.

12. A computing system, comprising:

a touch-input receptor;

a touch-detection module to track a touch input directed to the touch-input receptor; and

a control module to change a parameter of the computing system indicated by an initial portion of the touch input by an amount indicated by a subsequent looping portion of the touch input.

13. A method of interpreting touch input in a computing system, the method comprising:

tracking a touch input directed to a touch-input receptor, the touch input beginning with a source engaging the touch-input receptor and continuing until the source disengages the touch-input receptor;

recognizing an initial portion of the touch input as a mode gesture, the mode gesture being one of a plurality of different mode gestures;

recognizing a subsequent looping portion of the touch input that is linked to the initial portion of the touch input as a shared modulate gesture;

adjusting a parameter of the computing system corresponding to the mode gesture by an amount indicated by the shared modulate gesture.

14. The method of claim 13, where adjusting the parameter of the computing system includes adjusting the parameter by an amount indicated by an angular measurement of the shared modulate gesture.

15. The method of claim 13, where adjusting the parameter of the computing system includes adjusting the parameter at a rate indicated by an angular speed of the shared modulate gesture.

16. The method of claim 13, where adjusting the parameter of the computing system includes adjusting the parameter in increments indicated by an angular speed of the shared modulate gesture.

17. The method of claim 13, where adjusting the parameter of the computing system includes increasing the parameter responsive to the shared modulate gesture looping clockwise.

18. The method of claim 13, where adjusting the parameter of the computing system includes decreasing the parameter responsive to the shared modulate gesture looping counterclockwise.

19. The method of claim 13, where the touch-input receptor is a touch display.

20. The method of claim 14, where the touch-input receptor is a touch pad.
