Abstract:
A system and method of tracking a location of a head mounted display and generating additional virtual reality scene data to provide the user with a seamless virtual reality experience as the user interacts with and moves relative to the virtual reality scene. An initial position and pose of the HMD is determined using a camera or similar sensor mounted on or in the HMD. As the HMD is moved into a second position and pose, images of two or more fixed points are captured by the camera or sensor to determine a difference in position and pose of the HMD. The difference in position and pose of the HMD is used to predict corresponding movement in the virtual reality scene and generate corresponding additional virtual reality scene data for rendering on the HMD.
