CirculaFloor [locomotion interface]

The CirculaFloor locomotion interface's movable tiles employ a holonomic mechanism to achieve omnidirectional motion. Users can thus maintain their position while walking in a virtual environment. The CirculaFloor method exploits both the treadmill and footpad, creating an infinite omnidirectional surface using a set of movable tiles. The tiles provide a sufficient area for walking, and thus precision tracing of the foot position is not required. This method has the potential to create an uneven surface by mounting an up-and-down mechanism on each tile. This article is available with a short video documentary on CD-ROM.
