I don't care to hear about the consent you received for this controlled study. I care to hear about how I/we can opt-out from something like this when it is eventually deployed in the wild en masse as part of an actual product. I'm pretty sure that's what OP was also asking about. Can you elaborate on that?
Here are the principles we are using when developing these products:

In practice, it will mean that some things you will know about, but don't necessarily give consent (i.e., someone taking a picture or a video of you), while other will likely require consent (i.e., recognizing you in these pictures/videos).
This would be outright illegal in the EU.
Even someone is taking photos / videos of me this person is not allowed to share those with third parties without my consent.
If this content is going straight to FB this wouldn't be legal in the first place.
Of course FB is fine with that as they just shift the responsibility for the illegal actions onto the person who is uploading things without consent. (Same "trick" as with phone contacts upload).
FB is using a legal loophole here. Nobody will sue his / her friends. And even if someone tried, it's after the fact anyway: FB can't be forced to "unlearn" the gathered information.
Is that really true? Does that mean every tourist taking photos with an iCloud connected phone is violating some European law?
This makes me and so many others upset. I hate that people can upload photos of me to social media without my consent. And with the new glasses, it’s disingenuous to even say I’ll even know it’s happening. The little light on it is a bad solution.
