OLED data glasses give wearers an eyeful

You don't need to work for the secret service or as a jet fighter pilot to appreciate the sheer convenience – and craftiness – of being able to grab hold of crucial information, without so much as lifting a finger or batting an eyelid. 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.
