Abstract
A wireless transmission system for transmitting data to a user in a simulation system includes a light source for generating a modulated light beam for transmitting the data, an active pointing mechanism for actively pointing the light source, an optical receiver carried by the user for receiving and demodulating the modulated light beam, and a display or audio source for using the data to provide stimuli to the user. The light source preferably includes a laser device which is intensity-modulated with a wave form appropriate for the audio and video interfaces being used. The active pointing mechanism preferably includes a two-dimensional gimbal which receives tracking information from a tracking detector that tracks the optical receiver, and which uses that tracking information to actively point the light source. User position and head orientation are wirelessly tracked via optical sensors or feedback from user-worn sensor data.
