incrediBILL for someone such as you that has always been deeply involved in technology development even you must have a sense of awareness of when a new technology is crossing the line of creepiness.
If you want creepy just look for freaks wearing blue tooth all day like it was fashion jewelry or something. If you don't know they're on a cell phone they could easily be confused for a schizophrenic pacing back and forth talking to themselves. I've come close to calling men in white coats a couple of times before I saw the ear-bud cord or blue tooth hidden in hair. Oblivious zombies driving while talking or texting and nearly killing everyone in the path of their big SUV is creepy too yet they're everywhere.
What's creepy about having a heads up display that can help your navigate your car or assist with walking directions when on foot? I've always wanted a heads-up display in my car but it'll probably never happen in my price range in my life but this, which can be an obvious next step for Google Navigation, is cool enough for the price all on it's own IMO.
Now imagine you also get an app called Google Safety, along the same lines as Google Safe Surf for the B&M world that warns you about real danger, not just cyber danger. Google Safety would tie Google Local to police reports and such and warn you in real time not to go into the bar that banned Google Glasses in the first place because of the high rate of police response to violence at that bar. Not only that, it could tap into mug shots of known criminals, sex offenders, etc. and warn you about people to avoid before something bad happens.
If something bad does happen, you might just have it all on video streaming to the cloud in real time and there won't be any problem with witness issues and identifying the person that mugged you, you'll just go to video and show the cops whodunnit.
When you call 911 they'll know your location and be able to review what happened before they get there and have faces of suspects on a BOLO in under 5 minutes.
With everyone wearing them it could be the end of personal crime as we know it because nobody would ever be able to get away with anything ever again. No more he said she said, just review the tape.
Not only that you'll never miss getting pictures of the kids first step, first words, the interview where some dumbass says "sorry, we don't rent/hire/serve your <fill in type> here", all on video as people will quickly forget everything is being recorded until you show the jury the video.
I've been waiting for this stuff since I read Arthur C. Clarke's "Imperial Earth" and some other scifi stuff that predicted similar technologies when I was a teen in the 70s and now it's all starting to come true at a rapid pace.
Put the machine aside, dang it. Let's talk.
Assuming I remember your name. I'm horrible with remembering names as I know so many people but Google Glasses could fix that by adding facial recognition to all my contacts and everyone I ever meet from the point of owning those glasses would permanently be logged and accessible, possibly including searchable transcripts of conversations that link directly into a timeline of possibly stored video of the encounter.
Imagine you go to a conference (Pubcon?) and all the attendees that registered are in the database and you could tap into that and Google Glasses would show you the names of people as that walk by or even let you locate that person based on his/her current GPS coordinates. Obviously it would be opt-in for attendees, but it could be the ultimate networking tool ever for a large event with lots of people.
Of course this could all be done with a cell phone today.
Just get a chain and hang the phone around your neck with the camera facing forward and write the necessary apps and get lots of batteries.
