I've heard recently about this company that makes consumer eye-tracking devices for laptops/tablets. Then I rembered that back in 80s I was reading about how military flight training simulators from that period (not sure if this still applies today) had eye-tracking, so that only what is in the focus was rendered with lot of details (as a test focus on just one word here and without defocusing try to precieve how small angle of focus actually is).
This made me start thinking - is it possible to make a game with this approach, and then implement tech similar to described so that only small area that is actually in our focus is vastly enhanced.
I've seen demo of the game that uses eye-tracking for control (no idea what came out of that at the end), so I'm guessing that tracking speed is not the problem...but not so sure about rendering part.
So, anyone with bit of knowledge (or just interest in topic), please chime in...
