I like this idea! I might put them on my glasses someday. I'd have a micro-projector set up to shine on my lens, and have it receive information from a radio signal transmitter going to my computer or a belt receiver, or maybe from a computer in my watch. It'd have voice recognition software and give me latest data, news, and could also record things I suppose from my field of vision. It might even monitor the motion of my eyeball and use that as data input. It could possibly receive all kinds of facial expressions, but i might need a more ambient capture.
I'd like to have such a feed for my computer, but perhaps in an environment where I am better protected by Constituional and Bill of Rights laws and maybe also from viruses and state adware.
