1. A haptic feedback device, comprising:
a touchpad operative to output a first signal indicative of a contacted location on the touchpad, wherein the touchpad includes a first region associated with a cursor positioning, and at least one other region, distinct from the first region, associated with a control functionality different from cursor positioning;
a computer to receive the first signal; and
at least one actuator coupled to the touchpad and configured to impart a force to the touchpad to thereby provide a haptic effect in response to said contact, said force being based on a second signal output by the computer.
