Citing anonymous Amazon sources, Reuters says the project is part of Amazon’s efforts to increase efficiency in the last 100 yards of a delivery. Codenamed “Amelia”, the smart glasses are based off the existing Echo Frames platform. Unlike the current audio-only Frames they would have an embedded display that could give a driver more precise directions — for example, turning left or right after getting off an elevator. Amazon is also exploring camera capabilities using that embedded display, enabling drivers to take photos of packages as proof of delivery. Theoretically, doing all this would allow drivers to carry more packages because the glasses are hands-free, while all those saved seconds would allow drivers to squeeze in more home deliveries in a single shift.
