Haptic feedback for touchpads and other touch controls
First Claim
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 wherein at least the first force is output substantially parallel to a plane of the touch screen.

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.

17. A method for providing haptic feedback, comprising:
-
generating a position signal indicative of a selected location in two dimensions of a touch screen configured to display a graphical image;
sending the position signal to a computer device;
using the computer device to generate a force signal responsive to the position signal;
sending the force signal to at least one actuator coupled to the touch screen; and
outputting by at the least one actuator a force to the touch screen. - View Dependent Claims (18, 19, 20, 21, 22, 23)
