Eye Phone

Anyone who has read Vernor Vinge's Rainbows End will not be surprised that science fiction is on the verge of becoming science fact. Says New Scientist:

A contact lens that harvests radio waves to power an LED is paving the way for a new kind of display. The lens is a prototype of a device that could display information beamed from a mobile device.

Realising that display size is increasingly a constraint in mobile devices, Babak Parviz at the University of Washington, in Seattle, hit on the idea of projecting images into the eye from a contact lens.

His research involves embedding nanoscale and microscale electronic devices in substrates like paper or plastic. He also wears contact lenses. "It was a matter of putting the two together," he says.

Great. Wait till people start driving with these things. And I'm sure I don't want to have all those horrible flashing animated banner ads flashing right in my eyes. (Retina-based advertising?) I like the idea in theory, but personally I think I'll take a pass.
