With Microsoft’s “Okay,” there’s been quite a bit of indie development going into Kinect, the results of which usually being cool tricks they were able to pull off, though none particularly applicable to games. That last bit changed when a man named Chris O’Shea got his hands on the motion-sensing peripheral. Utilizing Microsoft’s Kinect by hacking into it, the man modified the camera to allow users to play air guitar, though the current prototype isn’t entirely accurate.
Though he claims he has no plans to market his idea as a full-blown product, he does say he’d be surprised if game companies weren’t toying with the same idea with that goal in mind. See the video below, and check out more of his work at ChrisOshea.org.
