Nobody's goal here is to prevent recording without notification. It's impossible to prevent it, anyone who's used a digital camera since they were invented knows this. Stop misdirecting the conversation around Glass with moronic strawman arguments. The original article did not ask for a mechanism for preventing unnotified recording; it asked for a light to notify people you're recording them. This is a fundamentally different proposition that solves a different problem.

Whoa, relax. The original commenter's point was that you're adding in something that will give a false sense of security to others instead of trying to reorient the conversation towards having an always-on regards to other people and recording.

What does the red light solve, if not telling others that the glass-wearer is recording?
