Haptic stylus utilizing an electroactive polymer
First Claim
1. A stylus comprising:
- a body having a first end and a second end opposite from the first end, the first end having an aperture;
a tip positioned within the body and adapted to move between a first position and a second position, wherein the tip is exposed through the aperture when in the second position; and
an electro active polymer actuator coupled to the tip and configured to move the tip from the first position to the second position upon being activated.

Abstract
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.
