An omnidirectional treadmill is a device that allows a person the ability to perform locomotive motion in any direction. The ability to move in any direction is how these treadmills differ from their basic counterparts (that only permit unidirectional locomotion). Omnidirectional treadmills are often employed in immersive virtual environment implementations to allow unencumbered movement within the virtual space through user self-motion. An advantage to having a treadmill installed is that it limits the actual movement of the system user within the enclosure while still providing context cues which simulate physical traversal through the virtual terrain.
