【発明の名称】電気活性ポリマーを利用する触覚装置及び触覚方法
Document Type and Number:
Japanese Patent JP2003534620
Kind Code:
A
Abstract:
Haptic feedback interface devices using electroactive polymer (EAP) actuators to provide haptic sensations and/or sensing capabilities. A haptic feedback interface device (12) is in communication with a host computer (14) and includes a sensor (112) device that detects the manipulation of the interface device by the user and an electroactive polymer actuator (18) responsive to input signals and operative to output a force to the user cause by motion of the actuator. The output force provides a haptic sensation to the user. Various embodiments of interface devices employing EAP actuators are described, including embodiments providing direct forces, inertial forces, and braking forces.
