Abstract:
A remote pointing apparatus including a remote control that generates an optical signal that is periodically expanded and/or reduced around the origin and an optical sensor that detects whether the optical signal is received, and a remote pointing method therefor. The remote pointing method includes projecting an optical signal that is periodically expanded and/or reduced around an origin; detecting whether the optical signal is received using a plurality of optical sensors that are two-dimensionally disposed; and detecting the position of the origin, which exists within a position recognition range including at least a polygon having the optical sensors as vertexes, based on the results of detection of the optical sensors. Since the remote pointing apparatus and method do not need a light receiving panel that is installed to fully cover a display screen or installed in vertical and horizontal directions of the display panel in order to receive a laser beam, a manufacturing cost thereof can be reduced.
