Future of the Screen: Terminator-Style Augmented-Reality Glasses
The idea of VRD was first tossed around at the University of Washington's Human Interface Technology Lab back around 1991. Thomas Furness, who'd been working on helmet-based displays for the Air Force in the '80s, and research engineer Joel Kollin were part of the team that put together the initial (and enormous) prototype. The concept was that tiny, ultra-low-power lasers could paint an image onto the human retina by scanning across it at high speed, essentially treating it as a tiny TV screen. If you could assemble a set of microscopic red, blue and green lasers, stick them where they could project onto your eyes, and hook them up to a computer, you could still see whatever you'd normally see, but with three-dimensional, full-color displays of additional information or imagery overlaid on the visible world—an effect called "augmented reality." Think of Arnold Schwarzenegger's sunglasses in Terminator, and you're on the right track.
