The augmented reality glasses would be able to show the wearer information about their surroundings. Google Maps and other GPS data sources could project information onto the lenses in a 'heads up' display or to project images onto the retina inside the eye.
Imagine walking up to a store and having your glasses inform you about the hours of the store, as well as deals offered. Directions to your next location projected in front of you without you getting your smartphone out of your pocket!!
