Contact lenses as heads-up displays

Contact lenses to get virtual graphics 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.

"One of the limitations of current head-up displays is their limited field of view. A contact lens display can have a much wider field of view. 'Our hope is to create images that effectively float in front of the user perhaps 50 cm to 1 m away,' says Parviz."
