Programming Google Glass to play blackjack (basic strategy or a card-counting system) seems like a much more tractable problem. Watch the table, count the cards and recommend the optimal play.

I believe these sorts of wearable computing devices are already banned in most casinos.

The blackjack games most casinos spread don't allow for a positive expectation, even when counting cards, and any card-counting software would obviously be banned by any casino.

It's already against the rules to use your phone at the table, even to look up basic strategy. Although it's not against the rules of most casinos to have a paper basic strategy guide, and most dealers are more than willing to give you basic strategy if they remember it.

It's true that terrible games have been proliferating lately (eg, 6:5 payoffs replacing 3:2), but can you really back up the claim that most casinos don't have a positive expectation (with counting) blackjack game? Do you just mean that to make it a positive expectation game you would need to use such a wide bet spread as to make the card-counting obvious? (Even then, I'm suspicious; Nevada is full of countable games. And are you ignoring strategy variation?)

It actually doesn't have to work at every casino; it would suffice if it worked at the casinos that had a good game - and a good glasses app could tell you which games were good. So yes, the glasses would have to be banned at the table.

I wonder what are the policies for cell phones?

You can have a cell phone in your pocket but they won't let you use it for anything. I suspect in the era of smartphones that they would completely ban them from the floor if not for the fact that enforcing that rule would be a nightmare.

No cell phones allowed at the tables. If you want to use your phone you have to stand up and walk away.
