You can now order the Virtuix Omini treadmill, a walking controller designed for use with the Oculus Rift headset.
You can order a Virtuix Omni for $500, which includes the treadmill itself, a support harness, and a pair of shoes.
You can also purchase two for $1,020, which combines shipping, so may be less expensive than purchasing two separately – in the US, anyway; freight won’t be calculated till closer to ship date.
The hardware is expected to ship in March 2014.
Virtuix Omni’s aren’t just one-way treadmills; they’re omni-directional, so you can run about in any direction in-game.
If you’re wondering how a full set-up works, here’s a demonstration showing a Team Fortress 2 player using a prototype treadmill, an Oculus Rift and a Kinect.
