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.
