Google today released a video looking at the possible uses of their wearable augmented reality glasses, Project Glass.
The video is obviously augmented itself and is intended to demonstrate what the glasses might be able to do. However I believe Project Glass are already testing working prototypes of the glasses.
Location and Google Maps feature prominently in the video. One of the Google Directors behind Project Glass is Steve Lee who has previously worked on Google Maps for mobile and location services.
It seems likely that when Google are ready to release these augmented glasses onto the market that location services will be one of the central features.
