Keep in mind that, like most of the things designed at the Media Lab, this was built to look really good in demos. The movements are big and inefficient so they will show up well on stage and on camera.

In the real world the movements might be much more subtle. Certainly no broader than, say, American Sign Language, which is quite analogous to what we are reinventing here.

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.
