CirculaFloor is a locomotion interface using a group of movable tiles. The movable tiles employ holonomic mechanism that achieves omni-directional motion. Circulation of the tiles enables the user to walk in virtual environment while his/her position is maintained. The user can walk in arbitrary direction in virtual environment.
It looks like a fascinating system, but based on the video, I’d guess that it will need at least a couple more tiles to allow people to walk at an average pace.
