Haptic feedback for touchpads and other touch controls
First Claim
1. An apparatus comprising:
- a touch input device configured to generate a first signal in response to user input;
an actuator configured to generate haptic force in response to a haptic force signal that is based on the first signal; and
two processors comprising a local processor and a host processor, wherein at least one of the two processors receives the first signal and at least one of the two processors generates the haptic force signal.

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.
