Microsoft Research is offering an SDK (Beta) for the Kinect, the motion and audio camera which launched last year for the Xbox. The SDK has some pretty cool features even for those who are just getting started: you can track the body motions of up to two people, identify which person is talking, and even hook up to a speech-to-text SDK to figure out what they’re saying.
I can only imagine what sort of industrial applications – not to mention new gaming experiences – people are going to come up with using this. How about a system which can actually detect nervous fidgeting in the security line at the airport? Or maybe computer-driven patient rehabilitation?
