The Oculus Rift has promised true immersion in games, but its always struggled with input. How can you really feel like a skydiver if youre sitting on the couch, holding a controller? Birdly, an installation at the Zurich University of the Arts, is probably more like being in one of Leonardo da Vincis flying machines than turning into a bird, but that remains an impressive sight. Devices like the Omni Virtuix treadmill can let you \walk\ through virtual environments, but this is the most complex Oculus Rift VR hardware weve seen, outside the realm of very specific training simulators. Gloves and bodysuits have been used for interaction in the past, but so far, Oculus Rift developers have tended to rely on simple game controllers.
