Abstract
Mechanical surface of rotational elements for motion compensation of a locomotive object. A single layer of rotational elements formed as a mechanical surface on which a human can stand and/or move, and which automatically compensates for diverse human locomotion such as translation in two dimensions and rotation. The surface can be used to actively sense and compensate for varying speeds of human motion while in locomotion on the surface. The layer allows a user to move freely within a confined area and to be maintained within the confined area via motion compensation. Thus, the surface is particularly suited for immersion visualization environments where user motion on the surface is translated into user navigation through a virtual environment such as for computer games and simulation without necessitating constraints on immersive scene projection or participant motion.
