A haptic feedback touch control used to provide input to a computer. A
touch input device includes a planar touch surface that provides position
information to a computer based on a location of user contact. The
computer can position a cursor in a displayed graphical environment based
at least in part on the position information, 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. The
actuator can move the touchpad laterally, or a separate surface member
can be actuated. A flat E-core actuator, piezoelectric actuator, or other
types of actuators can be used to provide forces. The touch input device
can include multiple different regions to control different computer
functions.
