1. A real-time virtual-reality simulation system for providing three-dimensional real-time video and stereo audio stimuli to a mobile user in a simulation space, comprising:

  • a wireless transmission system for wirelessly transmitting three-dimensional real-time video and stereo audio digital data to said user and wirelessly receiving tracking data from said user in a data communication rate of at least 295 Mbps, said wireless transmission system including a signal projector having a transmitter for generating a modulated light beam so as to transmit said digital data, and a tracker for actively tracking said mobile user so as to direct said digital data said mobile user and thereby update said digital data to correspond with a viewing orientation of said user; and

    a user module carried by said mobile user having at least one optical receiver for wirelessly receiving and demodulating said modulated light beam and at least one optical transmitter for wirelessly transmitting said tracking data corresponding to said viewing orientation of said user to said projector, and a converter for converting said demodulated light beam to said stimuli to said user, wherein said wireless transmission system is operatively connected to said user module so as to simulate a virtual-reality environment for said user who roams freely in the simulation space, and said at least one optical receiver is operatively formed so as to un-obstructively receive said modulated light beam and to maintain direct communication between said signal projector and said optical receiver via said tracker.
