DIGITAL CLAY Sharon Wu, Mark G. Allen Digital Clay is proposed as a next generation human-computer interfacing device based on a morphing, tangible and haptic surface. Digital Clay could be described as a “3D monitor” whose pixels can move perpendicularly to the screen to form a morphing surface. Users can view, touch and modify the shape of the working surface formed by these “pixels” (i.e.,the tips of micro hydraulic actuators). The bubble-shape actuator array and piezoelectric micro valve are currently being investigated.
