Abstract

A three-dimensional coordinates input apparatus in which a hand detecting plate and finger detecting portions are set into contactless states for the hand and fingers and the hand detecting plate and finger detecting portions are moved or rotated in accordance with the motions of the hand and fingers, thereby obtaining graphic data. When an object of three-dimensional computer graphics is grasped by the hand of the graphics based on the three-dimensional coordinates data, the finger detecting portions are depressed to the fingers in the real space, thereby giving a tactile sensation to the fingers. Further, the motion of the hand is detected by an infrared sensor.
