My experience for the last two years is that usually there are 2 or 3 people sitting around in any public place with their phones/tablets out pointed in my direction. Those phones/tablets have a camera (most have two at this point). They can be turned on remotely by software running in a background process. In addition almost all public spaces have more than one surveillance camera. I don't think merely avoiding google glass wearing people will help much. To be effective you should probably avoid anyone with a phone/tablet that is not in their pocket and stay out of public spaces (maybe live in the woods). Why not complain about Gorgon Stare instead? Since it is more likely to be used for infringing rights and you have more of a legal case (preventing unwanted photography in public was lost long ago). >"The system is capable of capturing motion imagery of an entire city, which can then be analyzed by humans or an artificial intelligence, such as the Mind's Eye project being developed by the Defense Advanced Research Projects Agency. [..] It is a spherical array of nine cameras attached to an aerial drone." -http://en.wikipedia.org/wiki/Gorgon_Stare http://en.wikipedia.org/wiki/Gorgon_Stare
