It's pretty obvious if you are not paying attention to your surroundings while using Glass, your eyes shift up (you have to to see the screen) and it's clear you've zoned out. "what is the user looking at on their screen, are they present, or distracted? Are they here and paying attention? Are they publishing this online right now? Or later?" is a made up problem. The other issues brought up may be entirely valid, but this one isn't.
