1. A device comprising;
- a housing having a touch surface adapted to be touched by a user;
a sensor coupled to the touch surface and configured to detect at least one of a position or movement of the user'"'"'s touch on at least a portion of the touch surface, the sensor configured to output sensor signals associated with the position or movement; and
an electroactive polymer actuator coupled to the housing and configured to output a haptic feedback force upon receiving an control signal from a processor, the control signal being associated with the output sensor signals.

Abstract
Haptic feedback device and method for using an electroactive polymer (EAP) actuator to provide haptic feedback force sensation to a user. The device includes a sensor that detects the a user'"'"'s touch on a touch surface and an electroactive polymer actuator responsive to input signals from the sensor outputs a haptic feedback force to the user caused by motion of the actuator.

15. Logic encoded in one or more tangible media for execution and when executed operable to perform a method, the method comprising:
-
receiving a sensor signal associated with a sensed position or movement of a user'"'"'s touch on a touch surface having a sensor coupled thereto, wherein the sensor outputs the sensor signal; and outputting a control signal to an electroactive polymer actuator upon the sensor signal indicating the sensed position or movement of the user'"'"'s touch is at a designated haptic feedback force location, wherein the electroactive polymer actuator output a haptic feedback force to the touch surface upon receiving the control signal from a processor. - View Dependent Claims (16, 17, 18, 19, 20)
