Jamie Hyneman is pitching a project to build prototype VR roller skates; not as a game but as a way to save your shins while using a VR headset.  The design places motorized wheels under your heel and a track under the ball of your foot which will move your foot back to its starting position if you walk forward.  If all goes as planned this should allow you to walk around in virtual worlds without running into walls, chairs or spectators and perhaps allow games to abandon the point and teleport currently in vogue.  There are a lot of challenges as previous projects have discovered but perhaps a Mythbuster can help out.  You can watch his pitch video over at The Register.

"Hyneman's pitch video points out that when one straps on goggles and gloves to enter virtual reality, your eyes are occupied and you therefore run the risk of bumping into stuff if you try to walk in meatspa ce while simulating walking in a virtual world. And bumping into stuff is dangerous."
