PURPOSE: To form a vibrating type tactile display which changes a contact sense to the plane to be contacted by vibrating and driving microcontactors arranged in the form of a plane with an arbitrary timewise and spacewise pattern, thereby synthesizing and displaying a contact sense toward various material bodys including virtual objects.
CONSTITUTION: Arrangement in the form of a plane is possible by having the contactors 1 used in common with wires to act also as transmitters of vibration and extending the wires up to the vibrators 4. Further, the arranging planes having an arbitrary area are possible to constitute when units, each of which has the contactors 1 and vibrators 4 bundled in several pieces in the reverse direction, are arranged. Driving is achieved with the contactors 1, piezoelectronic elements for generating the vibration and mechanisms for expanding the displacement thereof. In addition, the timewise and spacewise pattern is controlled by an electronic circuit including a calculator. Further, the structure is simplified when the contactors 1 themselves are constituted of the piezoelectronic elements and integrally molded with the vibrators 4.
