Virtual reality immersion system

An apparatus for a immersing a user in a three dimensional virtual reality environment room, comprising:

• a head mounted display worn by a user;
• wherein said head mounted display comprises a video camera and video display;
• a plurality of target markers;
• means for distributing said plurality of target markers within said room;
• wherein each of said plurality of target markers are distinct from all other target markers in said plurality of target markers and distinct from rotated versions of itself;
• a module for receiving a video signal of a portion of said room from said video camera;
• a module for identifying at least one target marker in said video signal;
• a module for calculating user position within said room using relative positioning of identified target marker(s);
• a module for streaming three dimensional video content to the user through said video display;
• and
• a module for dynamically repositioning the user's perspective viewpoint within said three dimensional video content by using said calculated user position to adjust position and viewing angle within said three dimensional video content.

A process for tracking a video camera in a three dimensional virtual reality environment room, comprising the steps of:

• providing a video camera movable within said room;
• providing a plurality of target markers;
• distributing said plurality of target markers within said room;
• wherein each of said plurality of target markers are distinct from all other target markers in said plurality of target markers and distinct from rotated versions of itself;
• receiving a video signal of a portion of said room from said video camera;
• identifying at least one target marker in said video signal;
• and
• calculating video camera position within said room using relative positioning of identified target marker(s).
