ABSTRACT:
A virtual reality viewing system and method senses the motions of a viewer providing a sequence of viewing perspectives and creates a real time image to the viewer based upon a probable viewing image. The system and method accounts for latency between the movement of the viewer and generation of the viewed image by generating a spline based upon measured velocities of the viewer's head and creates a look-ahead velocity based upon the spline and a dampening factor. Then an image is generated based upon the look-ahead velocities and displayed to the viewer. The dampening factor smoothes the look-ahead velocities by adding latency back into the look-ahead velocities to account for sudden movements of the viewer.
