I'd like to propose another use case: HUDs.

I've recently took up cycling to work and back, and would love to have speed/gears/time up on the glasses, instead of having to look and focus down. Riding my scooter would also be better with it, since the speedometer and turning light indicators are a bit out of my normal field of vision.

Also, be able to see who's calling on the cell phone would be a plus (I've found that having the phone 'say' who's calling results in a jumble that I can't make heads or tails of, as most of the names are not English names)

Yes! Integrating it with your car to see gas (or battery) levels. No integration needed to see speed, directions, stop lights, traffic, construction ahead. You could take it one step further and crowd-source to find stolen cars or license-plates.

So it seems Orwell didn't anticipate that we would carry the cameras that spy on us with us ... take it a couple more steps further and the secret service have a system where they can look through anyone's [with smart-glasses] eyes at what they're seeing.

Imagine Boston if after the bombing the authorities could requisition the view of everyone over the previous hour (cached for your convenience) and run that through a mapping program that can literally recreate the 3D scene with peoples movements and interactions for that whole period. Awesome power.

One critical feature would be local storage of recorded video. It would be a huge invasion of privacy to pull images from innocent people, even if it is for the greater good, maybe. I don't know which side of the privacy debate I'm on. If there is unlimited transparency for citizens then there should be 100% transparency for the government, that's the only way.

The 3D mapping thing has already been done. http://arxiv.org/pdf/1209.5982v1.pdf
