Abstract:
This paper proposes a transparent electrostatic actuator for actuating tangible objects in a tabletop interface.The actuator is a planar actuator with two degrees-of-freedom, capable of actuating a small dielectric sheet placed on top. The feature of the actuator is in having mesh-structured electrodes, patterned on a transparent film using a conductive polymer. By applying pulse voltages to the electrodes, electrostatic force act on the charges induced on the sheet to produce step-wise motion. The transparency of the actuator enables this actuation while maintaining the visibility of graphics on a visual display underneath. To demonstrate the suitability of the actuator for a tabletop interface, we constructed a simple human-computer interaction system, in which a physical icon travels on the actuator placed on a flat panel display. In the demonstration, the user could interact with the computer by handling active and passive tangible icons. The actuator used in the system could actuate a small icon in a broad area of 300 mm by 300 mm, with application of 500 V pulse voltages.
