Umoove Experience: The 3D Face & Eye Tracking Flying Game starts off by registering your eye and head position, then lets you use very subtle movements to fly around a virtual world.

I downloaded the game, took it for a spin. I suspect there’s a bit of a learning curve here as I spent more time crashing into the ground or moving randomly than I did going where I wanted. But I definitely get the concept.

I love the fact that this tech is completely software driven. It’ll be interesting to see where it heads next. The company released an API in closed beta back in March, 2013, so third party developers can add the technology to their own apps.
