I'm terribly excited about this interface. I've been hoping that this is right path towards a Rainbow's End(http://en.wikipedia.org/wiki/Rainbows_End http://en.wikipedia.org/wiki/Rainbows_End) kind of interface. I was worried that this kind of approach would languish inside MSFT research. http://www.extremetech.com/extreme/133732-microsoft-demos-muscle-computer-interface-air-guitar-hero-now-a-reality http://www.extremetech.com/extreme/133732-microsoft-demos-mu... Are you worried about the MSFT patent? Having your arms hanging loosely or with the elbow support while gesturing seems to be the right way to take advantage of human fine motor control while manipulating a digital interface. It is a good workaround to Gorilla arm. I suspect that the 20 year interface that Gabe Newell is expecting will use this kind of input. http://www.theregister.co.uk/2012/07/26/valve_considered_tongue_controlled_interface/ http://www.theregister.co.uk/2012/07/26/valve_considered_ton...
