Thread spawned from the epic motion control thread. Here we discuss just the implementation of Kinect. I've copied over a few posts as a starter. It'd be worth having a link to a description of the tech if anyone can provide me with something conclusive.
Perhaps Ms didn't ditched the internal processor after all? The Prime Sense site says that they need one of those fancy tvs with onboard processors to be able to use their camera...
What i mean is that perhaps the performance figure Ms gave was just the overhead for using the system, even if all the processing remains inside the camera. (TBH, i thought that 10-15% of 360's resources for all the computing natal is supposed to be doing seemed rather low)
Edit: On anther part of the site they that virtually no processing is required on the host computer using their camera...
But, i just read an interview, and it seems the reason why their camera is less expensive is not because of the on board processor, but actually because they don't use time of flight to evaluate depth, which according to them, needs some expensive sensors...
In some other site i saw its said they actually use the infrared led to project bar codes in the room, the sensor, which is really simple as it doesn't to have the super fast shutter speed time of flight requires, only receive that image, and depth evaluation is made based on the distance from these bar codes... Thought i don't know whether that's true or not.
They were at CES, this is likely what people were seeing at the show.
Interestingly there official site links to an article saying that they are in competition with Natal:

Its an Israeli company. What was the name of the Israeli company that MS bought?
This device does the processing locally aparently but only costs $20-$30 for companies to incorporate into there devices? If true makes MSs decision to remove the processor to get to a $50 pricepoint look a little strange. Link gives a bit of info on how it works also:

At $20 sounds like a good alternative to PSEye for the Arc system
EDIT: Actual specs: http://www.primesense.com/category/reference_design
Quite impressive, accurate to 3mm on xy axis and 1cm on z, at a distance of 2 meters. Id expect finger tracking to be possible at that level of accuracy.
Looking further into it MS bought the company 3DV and was also working with PrimeSense in some capacity. Id take a guess that they are using the time of flight camera tech from 3DV(or there tech is based on same principal so bought them for legal reasons) and possibly the work they did with PrimeScene was bassed on there NITE middleware which is the part that works out the skeletal structure from the 3D image produced by the sensor. Total guess though.
