Treadmills are usually used solely for cardio workouts, walking in a one way, linear direction. Virtual Space Devices is working on a concept that would make treadmills omni-directional, making the treadmill sense which way you are moving and adapting to that position.
You might be asking yourself, why the hell would I care about a new exercising device? The cool thing about a omni-directional treadmill is that it could make the play of virtual reality type games more realistic, adding the crucial element of movement to full figured games. Imagine a online multiplayer game, where your character isn’t controlled using only your hands, but your whole body. Talk about RPGing. — Andrew Dobrow
