Patent ID: 8405752

Claim:
An electronic device, comprising: a three-dimensional display device comprising a two-dimensionally arranged plurality of three-dimensional display elements each including a rod and an actuator which causes the rod to move vertically; a storage device which has a three-dimensional form of a desired switch stored therein; a three-dimensional display control device which separately controls heights of the rods via the actuators of the plurality of three-dimensional display elements based on the three-dimensional form of the switch stored in the storage device and deforms an upper surface of the three-dimensional display device to match the three-dimensional form of the switch; an image capture device which acquires an image of a subject; an extraction device which extracts a switch image that is included in the acquired image; and a form detection device which detects a three-dimensional form of a switch based on the switch image extracted by the extraction device, wherein the storage device stores the three-dimensional form of the switch detected by the form detection device as the three-dimensional form of the desired switch.
