But how the teachers will check their facebook and complain on twitter then?

Nah, the late MS pro-privacy campaign is more of a PR stunt (aka "we are doing something different than google"). Their record is more or less on par with Google (they have Bing that is just as information hungry).

The only reason we didn't see many headlines about that is because MS don't really do much innovation these days and no one cares.

I imagine article like that would break nda's at this point. Google never opposed rooting in any case, so I just don't see this as being a problem.

Except that it you have to activate video recording manually.
And it would kill your battery in an hour if all that was running without your notice.
And source code is published so you could check that it's not happening.

As pointed out many times before, you can do much more stuff with your smartphone and you can still enforce "no glass" policy on your property.

It's rather easy. All you have to do is leave your phone on the back seat of your car. If you want to go to the greater lengths, you might want to consider a trailer, or possibly a train.

Probably the guy has an arts degree, don't bully him...

Well, I imagine that they would be slightly "rude" than phones and tablets, but not by much:

As the screen is positioned near the top of the eye, you would still be clearly able to tell quite clearly when the person is looking at you and when his eyes jump upwards towards their small screen (unless you on a significantly elevated surface),

They would not be recording all the time either - I imagine that would just kill the battery life. In fact, given that the batteries on these are bound to be rather small, I imagine you will probably be able to do much less recording with these than with your smartphone. Not to mention, that by looking at this it seems that the recording etc is voice activated (or will involve some fiddling with with the glasses, which might give you a hint).

As far as "analyzing" goes, there was an article about app that will try to identify people based on what they are wearing , but I'm very skeptical when people begin to talk how good it is, but anything beyond human shape recognition is still borderline fiction these days ( at least for the consumer devices).

No one respects the conventions at this point anyway and I don't see much point in using them any more. Big companies just register everything available anyway, and small ones has to deal with trolling an scamming. It's just an extra vector for profit to some people, the way I see it. I'd say just drop the requirement for TLDs and let the people use current ones if they want to.

You don't have to upload photos of yourself - there are always those school photos that pop up (where you would offend a bunch of people if you untag yourself) or random photos by other people you didn't even notice being taken... I'd say not using facebook is the only way to protect your privacy, unless you live in a deserted island.

Well, considering how "advanced" facial recognition is these days, I'd say it's just a matter of finding the right dog, which would pass their filters...

I am also blind and don't see anything in general.

Most likely, however the process of entering all of those parameters into a computer might have an undesired side effect on the set of girls in question.
