If you wear Facebook glasses, don’t be surprised to find yourself asked to leave them at the box office when you attend a live performance, take part in a meeting, visit court, or even wander around some shopping malls. As word spreads, it will become a social faux-pas to wear them at social gatherings. People don’t trust Facebook on privacy.
What Apple learns: We know Apple supports privacy (or used to). When it chooses to introduce its own glasses, it will need to create location-based technologies through integration with Maps that enable destinations to prevent filming from taking place.
It also seems likely an activity light will demonstrate when filming/recording is taking place. Privacy advocates will demand the latter, while certain locations will require the former.
