Display technology vendor Lumus showed off its newest optical engine, the OE-31. Taking advantage of the very latest tech., the OE-31 is a compact transparent HUD that you can stick into motorcycle helmets, prescription glasses, sunglasses, fashion eye-wear to even skiing (and we'd imagine diving) glasses. The optical engine is a little more than just a small display, it is backed by a small sensor that sees things from your perspective (in a mechanical sense), and overlays information accordingly (such as a GPS overlay for bike helmets, or finding your way around The Pentagon), in other words, it's an augmented reality engine that's a lot more compact.
The new sensor design allows for a 19-degree field of view and a full-color, 640x360 picture display, which Lumus believes will be sufficient for reading a lot of text, its viewing experience should be comparable to watching a 40-inch screen from 10 feet away.
