Haptic feedback interface devices using electroactive polymer (EAP) actuators to provide haptic sensations. A haptic feedback interface device is in communication with a host computer and includes a sensor device that detects the manipulation of the interface device by the user and an electroactive polymer actuator responsive to input signals and operative to output a force to the user caused by motion of the actuator. The output force provides a haptic sensation to the user. In an embodiment, a stylus including a body having a first end and a second end opposite from the first end, a moveable member coupled to the body and capable of being in contact with a user's hand; and an electro active polymer actuator coupled to the moveable member, wherein the electroactive polymer moves the moveable member from a first position to a second position with respect to the body upon being activated.
