Students at the Fraunhofer Institute in Germany are developing a pair of interactive data eyeglasses that can project an image onto the retina from an organic light-emitting diode (OLED) micro-display, making the image appear as if it's a meter in front of the wearer. While similar headwear only throws up a static image, the students are working on eye-tracking technology that allows wearers, with just the movement of the eyeball, to scroll through information or move elements about.
The glasses are designed to provide information to wearers who don't have their hands free to operate a keyboard or mouse.
