This is quite cool. Once you get past the first minute or so of preamble, you can see that the Kinect fires out a galaxy of IR dots into your room, presumably in a pattern it can recognize and use to determine distance.
It’s kind of weird to think that this is shooting out constantly, covering you in dots, but of course it’s the same IR light that emits from any light source, just at a frequency and pattern the Kinect can detect.
I suppose we’ll learn more about it as hackers start to reverse-engineer this interesting piece of hardware.
