Abstract
An immersive display system which provides for an optical correlator for imaging a surface and generating data representative of the position or movement of the optical correlator and any object physically associated with the optical correlator. Imagery is generated and displayed on a display device in accordance with the data generated by the optical correlator.
Claims12
A display system comprising:
- a display unit comprising an optical correlator configured to optically monitor a surface and generate an image output signal in accordance therewith;
- a navigation engine configured to evaluate said image output signal and a given reference snapshot to determine the position of said display unit, and to output a positional signal representative thereof;
- a visual display for displaying imagery generated based upon said positional signal;
- said navigation engine being configured to mathematically cross-correlate said image output signal with said reference snapshot, to determine an offset between said image output signal and said reference snapshot, and to output said positional signal to a connected system;
- and
- an omni-directional treadmill for generating an output signal in accordance with the direction and speed of a user's footsteps on the treadmill and for providing the output signal to said navigation engine.
