I hear a lot of good stuff about Kinect for the XBox 360.
However, my only "display" is a projector that is sitting right next to where I would be sitting/jumping. Since Kinect is basically a combination of several infrared-and-normal cameras, I would guess that a bright, hot projector would be quite a disturbance. I can not find any articles on the subject, though.
Do you know anyone who has tried this?
