This has the potential to be huge, especially since it's the brainchild of Google. One thing I noticed is that they didn't showcase object recognition of any type in the promo video. When I heard they were testing these glasses, Google Goggles is the first thing that came to mind. It would be really useful to auto-search objects by simply looking at them and issuing a command. I'm sure it's on their roadmap, if it's not already live in the glasses alpha/beta product.
