I still think this is where it's at for walking in virtual reality.http://www.youtube.com/watch?v=BQw1tsgrJOs
Yeah, in the treadmill's case, you can run, walk, and do any other movements in any direction you choose. You can even practically increase the size of the board. In the tiles' case, the machine would have to judge where the user was going to step, and the speed at which the tiles will move and respond.
i don't see how these are better than a treadmill. ooo they can raise up and down slightly...
