The Virtuix Omni is a virtual reality interface that allows you to move freely in a game.
As you run around in the game you actually are running in real life. You get a more immersive experience as well as a great workout! The system can be easily assembled. It requires that you wear special shoes of which you order right on the site. The system basically translates movement into analog gamepad input. You can get a full 360 degree view of your games.
