Several companies are developing prototypes for digital devices that look like stylish eyewear but may one day offer consumers an overlay image of virtual information like an electronic map or an arrow showing the correct way to a destination.

Using holographic optics, light-emitting laser diodes in the projector, stored in the side of the frame, shoot their highly concentrated beams forward to the eyeglass surface. There, computerized, holographic gratings diffract light in ways that ordinary optical components like prisms can't, steering it to the user's eyes.
