Until now, the Omni tracked your legs with a Microsoft Kinect. Todays Omni is more accurate and offers analog motion — which means that the faster you walk, the faster your character moves, with an unlimited number of possible speeds. After lacing up Virtuixs custom sneakers, which have slippery plastic pads on the bottom, I hopped inside the Omnis waist-high ring and strapped on a harness. Youre still very much grounded inside the Omni, but youre supported enough that you can walk on its slick curved base without the fear of falling. It takes a few minutes to learn how to walk in the Omni, since you have to lean forward trustingly with each step.
