Received-light pattern detection apparatus

摘要

A game system perceives a sign intended by a game player from the motion of a finger or hand of the player ans controls the motions of the game characters or the situation of a game in accordance to the sign. A game machine comprises a received-light pattern detection apparatus for detecting the motion of a hand of a game player as a received-light pattern; a sign perception for perceiving a sign from the received-light pattern input from the received-light pattern detection apparatus; and a main CPU from controlling a game in accordance with the sign perceived by the sign perception system. The light detection apparatus 10 is formed on the front surface of a monitor and comprises arrays of infrared light emitting and receiving elements 11 that are operated in sequence. Signs made by moving the finger across the face of the monitor in a curve or a series of straight lines are detected by breakage of the infrared beams.
