Google released a new promo video for its exciting Glass project, which is essentially augmented-reality glasses. The video focuses on the chat and image-capture features, but there is a shot near the middle of a person diving through a city and getting directions, and another shot near the end of the glasses providing flight information. I see three top uses for this technology in city life: (1) transit info, (2) driving directions, (3) information about nearby attractions and restaurants. Could we also see people walking around video-chatting as they would with a cellphone? Only time will tell.
