Abstract

A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch surface that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer'"'"'s display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses, vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.

Claims

1. A haptic feedback device, comprising:

a touch screen operative to display a graphical image and to output a position signal indicative of a selected location on the touch screen in two dimensions; and

at least a first actuator configured to impart a first force directly to the touch screen to thereby provide a haptic effect in response to the selection, the first force based on information output by a computer device.

2. The haptic feedback device of claim 1, wherein the computer device is a portable computer.

3. The haptic feedback device of claim 2, wherein the portable computer is chosen from the group consisting of a PDA, a pager and a cellular phone.

4. The haptic feedback device of claim 1, wherein the touch screen is provided in a housing that is separate from the computer device.

5. The haptic feedback device of claim 1, wherein the touch screen is operative to receive a location selection from a user'"'"'s finger.

6. The haptic feedback device of claim 1, wherein the touch screen is operative to receive a location selection from a physical object held by the user.

7. The haptic feedback device of claim 6, wherein the physical object is a stylus.

8. The haptic feedback device of claim 1, wherein the touch screen is integrated in a housing of a handheld device that is capable of operation by at least one hand of the user.

9. The haptic feedback device of claim 8, wherein the handheld device is a remote control device for controlling one or more functions of an electronic device or appliance.

10. The haptic feedback device of claim 1, further comprising a second actuator coupled to the touch screen to apply a second force to the touch screen.

11. The haptic feedback device of claim 1, wherein at least the first force is output substantially perpendicular to the plane of the touch screen.

12. The haptic feedback device of claim 1, wherein the first actuator is a piezo-electric actuator.

13. The haptic feedback device of claim 1, wherein the first actuator is a voice coil actuator.

14. The haptic feedback device of claim 1, wherein the first actuator includes a solenoid.

15. The haptic feedback device of claim 1, further comprising a touch screen microprocessor separate from the computer device configured to provide control signals to the first actuator.

16. The haptic feedback device of claim 1, wherein the touch screen is disposed in a housing that is separate from the computer.

17. The haptic feedback device of claim 1, further comprising a touch screen microprocessor separate from the computer device and configured to provide control signals to control the at least one actuator.

18. The haptic feedback device of claim 1, wherein at least one actuator outputs a continuous vibration or a pulse tactile sensation on the touch screen.

19. The haptic feedback device of claim 1, wherein the touch screen includes a first region and a second region.

20. The haptic feedback device of claim 19, wherein the first region is to provide the position signal and the second region configured to provide a different signal.

21. The haptic feedback device of claim 20, wherein the second signal is used in a rate control function of a value.

22. The haptic feedback device of claim 20, wherein the second signal is used in conjunction with a button press.

23. The haptic feedback device of claim 20, wherein the first and second regions are associated with different haptic effects.
