There's not much reason for Umoove to be on your radar unless you're huge into following the Israeli tech startup scene, but they probably should be. The studio just released Umoove Experience: The 3D Face & Eye Tracking Flying Game [Free] which is one of the best iOS tech demos I've seen in a while. Calling it a "game" is a little generous, as it's barely more of a game than Epic Citadel [Free], but where it differs is how you control it.
Using the front facing camera of your iOS device, the game is able to track the position of your face and eyes allowing you to control flight in game by surprisingly minor head movements. Games that utilize the front facing camera in interesting ways aren't exactly new, but most of them (Sega's Go Dance [$1.99] is a fantastic example) aren't very precise and require incredibly exaggerated movements to be detected.
To see the various ways that this tech can be used, check out Umoove's oddly epic trailer:
The Umoove Experience game is really pretty cool, and is totally worth downloading just to see how neat the Umoove tech is. The end game here for the company seems to be to get their two SDKs, FaceSDK and EyeSDK into as many games and apps as possible. I always love seeing developers come up with clever ways to deal with controls in iOS, and this is up there with one of the best.
Even if you only try it for ten seconds, Umoove Experience is still something you need to check out.
