Thank you for handwriting recognition example! Now I can re-state my question in much simpler way using this metaphor. So, if we say that Natal learned letters from A to Z, then I wonder what if some designer have crazy idea where he needs something like a drow house glyph, will Natal "alphabet" be enough?

...

Well, we don't know yet how much comprehensive the "training" has been for Natal's software. We have to hope that they gave it a very good coverage of the "human poses" alphabet. But as I said, there's an extra ace up the sleeve, that is knowledge about kinetic limitations of human body parts.

Even if you have to strike a really weird pose, you will have to get there from a normal one through intermediate, less weird poses. The software might be able to provide a good interpretation of the sensor's input just by extrapolating previous data of body parts' positions and speeds. I suppose that's what it will do not only when a limb is occluded from sight, but also when it has a very low matching score for what it sees.

It's an interesting problem, I guess we'll have to wait and see. I'm sure it will have plenty of quirks, my previous post was just meant to expand on the a priori knowledge base topic.
