Haptic feedback for touchpads and other touch controls
First Claim
1. A device comprising:
- a housing;
an input device coupled to the housing, the input device comprising a substantially planar surface configured to receive user input, wherein the input device is configured to generate an input signal based on the user input;
a first actuator coupled to the input device at a first position, wherein the first actuator is configured to impart a first haptic force to the input device at the first position based on the input signal; and
a second actuator coupled to the input device at a second position, wherein the first position is different from the second position, and wherein the second actuator is configured to impart a second haptic force to the input device at the second position based on the input signal, andwherein the first actuator or the second actuator is selectively actuated to provide the first haptic force or the second haptic force to the input device based on the first position and the second position.

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.
