In order to demonstrate the functionality of its "Omni" prototype treadmill, which the company calls a "natural motion interface for virtual reality applications," technology start-up Virtuix has released the above video of the contraption being used in conjunction with an Oculus Rift and Team Fortress 2.
The setup essentially works like this: The Oculus Rift handles head tracking and display duties, while a Kinect tracks how the player walks/runs on the the Omni, and then converts that input into in-game commands. The Kinect is an in-development solution, however, and Virtuix says the Omni will include its own sensor when/if it ships to consumers.
The company plans to launch a Kickstarter campaign in May, with final production units costing somewhere between $400 and $600, sans shipping. A second example video, this time showing a better look at a prototype of the device while in use, has been tucked away beyond the veil.
