Abstract

A system for actively resisting touch-induced motion includes a touchscreen device and a processing circuit. The touchscreen device includes one or more sensors configured to generate motion data based on a motion of a touchscreen display of the touchscreen device, where the motion is induced by a touch on the display. The touchscreen device further includes one or more motion control devices configured to apply a force to the display. The processing circuit is configured to determine, based on the motion data, a force to counteract the motion. The processing circuit is further configured to cause the motion control devices to apply a force to the display to counteract the motion of the display.

Claims

1. A method of actively resisting touch-induced motion, comprising:

generating, by a sensor, motion data associated with motion of a touchscreen display of the touchscreen device, wherein the motion is induced by a touch on the display, and wherein the touchscreen device includes;

the sensor; and

a motion control device configured to apply a force to the display; and

determining, based on the motion data, a force to counteract the motion; and

applying a force, by the motion control device, to the display to counteract the motion of the display.

2. The method of claim 1, wherein the motion data comprises acceleration of at least a portion of the display.

3. The method of claim 1, wherein the motion data comprises displacement of at least a portion of the display.

4. The method of claim 1, wherein the motion data comprises a force value applied by the touch to at least a portion of the display.

5. The method of claim 1, further comprising determining, by one or more processors, based on the motion data, a touch location on the display corresponding to the touch.

6. The method of claim 5, wherein the force is applied to an area that is different than the touch location.

7. The method of claim 5, wherein the force is applied to an area that is the same as the touch location.

8. The method of claim 1, wherein the motion control device is arranged beneath a surface of the display.

9. The method of claim 1, wherein the sensor includes an accelerometer coupled to the display.

10. The method of claim 1, wherein determining the force to counteract the motion includes determining a touch location on the display, and determining a motion of the display at the touch location induced by the force.

11. The method of claim 1, wherein counteracting the motion of the display comprises counteracting the motion at a touch location on the display.

12. The method of claim 1, wherein counteracting the motion of the display comprises counteracting the motion at an image location on the display.

13. The method of claim 1, wherein the force is applied after the touch.

14. The method of claim 1, wherein the force is applied during the touch.

15. The method of claim 1, further comprising generating, using a touch sensor, touch data based on a touch of the display.

16. The method of claim 15, wherein a touch location is determined based on the touch data.

17. A non-transitory computer-readable medium having instructions stored thereon, the instructions forming a program executable by a processing circuit to actively resisting touch-induced motion of a touchscreen display of a touchscreen device, the instructions comprising:

instructions for receiving, from a sensor, motion data associated with motion of the display of the touchscreen device, wherein the motion is induced by a touch on the display, and wherein the touchscreen device comprises;

the sensor; and

a motion control device configured to apply a force to the display;

instructions for determining, based on the motion data, a force to counteract the motion; and

instructions for causing the motion control device to apply a force to the display to counteract the motion of the display.

18. The non-transitory computer-readable medium of claim 17, wherein the motion data comprises acceleration of at least a portion of the display.

19. The non-transitory computer-readable medium of claim 17, wherein the motion data comprises displacement of at least a portion of the display.

20. The non-transitory computer-readable medium of claim 17, wherein the motion data comprises a force value applied by the touch to at least a portion of the display.

21. The non-transitory computer-readable medium of claim 17, further comprising instructions for determining, based on the motion data, a touch location on the display corresponding to the touch.

22. The non-transitory computer-readable medium of claim 21, wherein the force is applied to an area that is different than the touch location.

23. The non-transitory computer-readable medium of claim 21, wherein the force is applied to an area that is the same as the touch location.

24. The non-transitory computer-readable medium of claim 17, wherein the motion control device is arranged beneath a surface of the display.

25. The non-transitory computer-readable medium of claim 17, wherein the sensor includes an accelerometer coupled to the display.

26. A method for actively resisting touch-induced motion, comprising:

predicting a future touch location on a touchscreen corresponding to an expected touch;

predicting a future motion of the touchscreen based on the expected touch;

determining, based on the future motion and the future touch location, a force to counteract the motion; and

causing a motion control device to apply the force to the touchscreen.

27. The method of claim 26, wherein the force is applied to an area that is different than the future touch location.

28. The method of claim 26, wherein the force is applied to an area that is the same as the future touch location.

29. The method of claim 26, wherein the motion control device is arranged beneath a surface of the touchscreen.

30. The method of claim 26, wherein the force is determined based on a predicted internal flexure of the touchscreen.

31. The method of claim 26, wherein the motion control device includes a tensioner configured to control a tension across the touchscreen.

32. The method of claim 26, wherein the force is determined based on a predicted linear motion of the touchscreen.

33. The method of claim 26, wherein the force is determined based on a predicted angular motion of the touchscreen.

34. The method of claim 26, wherein the force is determined based on a predicted flexure of the touchscreen.

35. The method of claim 26, wherein the future touch location is predicted based on data provided by an application running on the display system, and wherein the future motion is predicted based on a history of the user touching the touch location.
