Just a guess from the types of sensors and the custom ASIC that was designed to integrate them... at 600 billion operations per second it certainly seems like it would be capable of real-time integration and validation of all those things.

I wonder if the ir camera could be used for other purposes. If it can actually read the temperature, that's a neat trick. Probably can't though (see prices of flir lepton), I'd guess it is a b/w camera sensitive in the 700-800 nm range.

But still, with the dot projector, and that kind of processing power, they should be able to detect 3d gestures, similar to leap motion.
