Lumus was showing off two different types of wearable displays, the development kit -- or DK-32 shown above -- and the PD-18-4 a monocular version using the same technology. Driven by Lumus' patented Light-guide Optical Element, a micro-display pod, and the Optical Engine which projects light into the lens -- where it is reflected back to the user's eye via reflectors embedded in the lens -- the Lumus' DK-32 delivers a bright 720p 3D-capable display that only weighs 27 grams. The effect is really quite impressive, the colors are bright -- and adjustable using the display pod -- and images were surprisingly clear. But the best part, of course, is that while you're watching YouTube vids and walking about you'll avoid stumbling into objects and passersby. Also on hand was the monocle which was very much like something you'd see in a science fiction flick. With the PD-18-4 we checked out a nav program, some eye tests, and a phone UI mockup. We're stoked at what this development kit will make possible once it gets into the hands of some evil genius. Video and pictures are just past the break.
