Tai Chi on Kinect

I previously mentioned the 3D computer program to teach you Tai Chi. I was a bit disparaging about it, but I see that it is possible to learn Tai Chi using Microsoft Kinect system and the Your Shape Fitness Evolved 2012 game. The graphics are far more sophisticated than the game from the previous post, and you can see quite a lot of subtly from the instructor.

It seems to me that this would have the potential to actually be a reasonable learning system as it is interactive. The closer you are to the correct posture the more points you are awarded. How fine-grained it is possible to determine your subtle posture to using the Kinect system is another question, but in principle this seems to me to be a very good idea.

I can hardly find any information about it on the Internet, so if anyone knows of anything or has any experience with it, please add some comments to point me in the right direction. I did find this video which gives you an impression of how it works. Essentially it is a couple of Russian guys mucking around, but if you can ignore them, you can start to see the system in action.
