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?


I am guessing it will be more like the OpenNI drivers, since PrimeSense is already a MSFT partner.


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.


I remember Ilan Spillinger (http://www.xbox.com/en-US/Press/Corporate/ilan-spillinger) saying something like that at a talk he gave recently- Microsoft Research played a huge role in the development, iirc.

/edit: This talk has some info about it http://research.microsoft.com/apps/video/dl.aspx?id=139295 (MSR guy starts around 1h00m)
