Evoluce, a German multi-touch display manufacturer, has used a Kinect hack to play the PC version RUSE with nothing more than gestures. Does it work? Yes, it does.
Watch the video below.
The right hand controls cursor movement, with the left hand being introduced as a left mouse button command for unit selection, giving orders, and so forth.
There's no doubt that this guy is properly playing an RTS, precision movements and all, using his hands in the air.
Watch and see. Nice to see Kinect hacks being used for actual games, rather than controlling a metal donkey, or whatever.
