Some time ago we were surprised by the idea of Stompz, a system that allows us to use our feet to walk, but without moving from the site. Its creators are looking for support on Kickstarter to launch it commercially.
The operation of Stompz is very simple and very effective: we place two devices at our feet, each one of which has inertial sensors, and our movements are captured and translated as if they were keystrokes or movements of a gamepad. As you can see in the video, the movements and gestures would be performed without moving from the site, which would not take much space to use Stompz, and the virtual reality experience would be much more immersive than playing sitting, since we could bend down or tilt physically. Its creators will also offer an SDK for those developers who want to implement native support by reading Stompz sensors directly. Of course, the devices are wireless, and the signal is transmitted to a receiver that plugs into a USB port. It is compatible with Windows, Mac, Linux, Android and iOS (with jailbreak).
