Saw this here (Lorna shared the link).
This does sound like interesting tech (though tracking larger joints and body position seems even more interesting). I do not see how it can handle some of the core use-cases though.
Pretty much anything that requires fine manipulation (triggers, buttons, throttles and HOTAS rigs) would seem to be out of the picture. Being able to track gross hand motion seems possibly within reach. Being able to pick up a glass in VR with hand tracking and then spin it around to look at the far side seems extremely challenging.
I can see this working in the near term for things like fighting games where you punch an opponent. I can’t see it replacing controllers or similar items for fine motor interactions…hoping they’ll prove me wrong though.
Ok, interesting…vive also seems to have some early access hand tracking with the vive and vive pro mentioned here.
