Several companies are developing prototypes for digital devices that look like stylish eyewear but may one day offer such capabilities to consumers. The glasses are called heads-up displays because the wearer can always look through them and see the real world - like the sidewalk just ahead - but can also see, on an overlay image, virtual information like an electronic map or an arrow showing the correct way to a destination. The glasses may also help the wearer remember the name of a long-lost friend she sees on the street.
