Abstract

A light pointer apparatus has a light source module for projecting a light beam onto a surface. The light pointer apparatus also has an image sensor module and a transmitter module. The image sensor module detects a position in the surface of a visible light spot generated by the projected light beam striking the surface. The transmitter module transmits the position of the visible light spot to a remote device for remote control of a device.
