Seriously, it's easier to covertly film somebody with your phone, at least you can pretend you're playing Angry Birds or something.
Image analysis of what you're looking at.
Having your glasses analyze what you're looking at is an extremely cool concept, but not really feasible for a Glass type device. The explorer addition could record video for just a couple minutes. Battery life is a huge problem if you don't want a cord hanging out of your glasses.
For a device that sees and hears what you see and hear, you need something more like this: https://www.spaceglasses.com/

I once saw a full grown man in tears while he was trying to write a simple Tizen app.
I attended a Hackthon once where a team was trying to write a Tizen app, and at the end of the Hackathon none of them were speaking to each other.

Sometimes there are benefits to a fad that we don't really see as developers. In my industry we call them "press release features". They may feel useless or even degrading to be developing, but they can have actual monetary value. For example a bank in the US just made a big splash by announcing that they will "support iBeacons". How will they be supporting iBeacons? I have no idea. I'm not sure that even they know. It's not important. What's important is that they got a lot of media attention, and give themselves a veneer of progressiveness.
