Beguiling sound and visuals aside this is a revolutionary method of interacting with computers. The primary concepts of computing as a “whole of body” experience are just being tapped. The intrinsic value of using the entirety of gesture support in a real world 3 dimensional way is that it opens full communication conduits and behavioral recognition strategies. This can effect, security, feedback mechanisms, detection, and so much more. Think of being able to evaluate stress based on body language and doing so over time. What are the health care implications of watching people and patterning them over a long period of time. I’ll not go into the details of having a 3 dimensional camera that could be remotely accessed sitting in peoples private spaces, but consider the interface to the computer in an organic and real way. I can’t wait to see this on a cell phone.
