The present invention provides a cost effective mobile object position, motion, and pitch and yaw attitude detector, wherein such mobile object is located in three-dimensional space and such detector employs light interaction between a mobile omni-directional light transmitter disposed on the mobile object, and a single stationary distance and direction vector sensing light receiver. The principles of the invention are particularly beneficial in a video game system, wherein the mobile transmitter comprises an omni-directional light element that uniformly radiates a fixed intensity of light across substantially 4 pi steradians of curvature. The stationary receiver detects the directional vector and the distance to the point-of-origin of light emitted by the light element, each with respect to the receiver, and thereby determines the position of the light element relative to the receiver. By virtue of the light element being disposed at one end of an armature held or worn by a player, the pitch and yaw attitude of such armature, or equivalent thereof, affect Y-vector and X-vector positional data, respectively, of the light element as detected by the stationary receiver in the above-described manner. Thus, the position, motion, pitch and yaw of the mobile object are each detected and thereby affect and interact with a video game of the video game system.
