Sci-Fi to Hard Science
If you were wondering how important local web information was to your boutique store, or how much detail and content you'd need for a tourist site, the answer is probably quite a lot, if Google gets its way. Imagine walking down the sidewalk wearing a pair of these with your content settings set to maximum input.
Stores could beam you offers that actually match your interests as you pass, on-screen maps could guide visitors to your shop that might be a little off the beaten track, while visitors could be guided around the area to places of interest, watch video history guides and tours. It could all be great, as long as there's the option to lower those content settings to "leave me alone."

Always on the run, always in touch

The developers seem to be treating Google Glasses as a big college project, allbeit a very well-funded one, and are asking for users' ideas and input. The site's first post states, "We’re sharing this information now because we want to start a conversation and learn from your valuable input. Please follow along as we share some of our ideas and stories. We’d love to hear yours, too. What would you like to see from Project Glass?"
Learning Opportunities
It also comes with the inevitable concept video, that combines Siri-like voice interaction, location-based services and most of what you get in a current smartphone, presumably an Android model.
Expect a lot more interest in the technology, but don't expect them to be on sale too soon as there are probably a whole host of regulatory steps to navigate before something like these become legal. You can see Google stocking a laywer's warchest for the inevitable lawsuits from jaywalkers not concentrating on where they were going.
