I have envisioned a similar system for about a year now. Except it uses a semi-transparant display over one eye and a camera mounted to that. You wear a glove over one hand and you interact not with a projected display, which I find to be shockingly impersonal, but with a 'virtual' display that could handle depth as well.<p>A nicer way to interact with your environment, I'd think, especially as when processors get stronger you could handle an entire virtual 3D environment overlaid over one eye.
