A company named Virtual Space Devices Inc. has created the omni directional treadmill (ODT). The treadmill can slide around on 2 axis allowing people to be immersed in a digital landscape and roam around freely. You will notice on the video above that when changing direction there is little if any inertial residue.
The device could be used for a number of things such as entertainment, exercise and business use. When used for business it could allow people to walk around a virtual building to see what it is like before it is built.
The whole idea looks quite cool. All we need now is something on the z-axis to replicate stairs and hills and we are set.

This is a really nice treadmill. However, I bet it costs an arm and a leg.
