WIRELESS POINTING SYSTEM IMPROVING DIRECTION DECISION ERROR

摘要

PURPOSE: A wireless pointing system improving a direction judgment error is provided to proceed exact pointing without a malfunction of direction judgment by applying a judgment algorithm according to a sensor condition value in a grid signal receiver. CONSTITUTION: A grid signal transmitter(100) passes a light in grid generations(131,132). The grid signal receiver(200) receives a grid pattern in at least a pair of motion sensors. The grid signal receiver decides motion of the grid signal transmitter. The grid signal transmitter occurs the grid pattern than the minimum thickness in a normal use distance in order that the thickness of a grid line is received thickly than an interval of a pair of motion sensors.
