I wonder how their motion tracking compares with PrimeSense's OpenNI and NITE. Does anybody know if this SDK provides full access to player tracking and gesture information, or is it basically like libfreenect, allowing access to the raw data?
It was my understanding that Microsoft doesn't use PrimeSense's gesture and motion tracking software, but instead wrote their own. Unfortunately, I can't remember where I read that.
I googled a bit, but wasn't able to find any corroborating evidence. Please post it here when/if you find it. In any case, it will be interesting to compare the APIs when MS releases theirs.
