Abstract—This paper describes a new type of computer-user interactions through an actuated real object and visual images on a liquid crystal display (LCD). The interactions are realized by three degrees-of-freedom (three-DOF) transparent electrostatic induction actuators placed on the display. The dynamic inter-action was realized using asynchronous driving characteristics of the induction actuator. The actuator does not interfere with visual images on the screen because of the optical transparency of the actuator. The actuator is equipped with eight sets of one-DOF actuators, which enables three-DOF driving, XY translation and rotation, of sheet objects. Fundamental performances of the actuator regarding the 3-DOF motions are investigated. Also, a prototype interactive application is demonstrated.
