Abstract
A light projection tag system provides for the detection of spatially coincident light patterns projected by competing players on a gaming surface. Each player is equipped with an optical transceiver with a field-of-view that is geometrically coincident with the light pattern projected from the transceiver. Each player's transceiver can detect when an opponent's light pattern, also projected on the gaming surface, enters this field-of-view thereby achieving a tag. Detection methods include the use of modulated visible or infrared light. Various embodiments of the system include automatic targets and projected gaming mazes.
