Sorry, I'm skeptical about that. The movements are big so that they will be captured and correctly interpreted by their pattern recognition system. I think they would not be able to detect very subtle movements like ASL. It is ingenious to claim that it was made artificially big and clumsy for the audience.

I think you mean disingenuous.

Thanks, I did mean that :)

Not so sure that these huge gestures are necessary, depending on the technology - You can play games perfectly fine on the wii with little more than the flick of your wrist.

But there the device itself has accelerometers, whereas here, at least if I uderstood it correctly, the camera has to capture the markers on the hand which is much more noisy.
