Imagine everyone with contact lenses that are hooked to computers in their pockets, with an audio/video input that recognizes faces/voices and can give you information about the person you are interacting with that only you can see and hear…

Engineers at the UW have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.

“Looking through a completed lens, you would see what the display is generating superimposed on the world outside,” said Babak Parviz, a UW assistant professor of electrical engineering…
 Drivers or pilots could see a vehicle’s speed projected onto the windshield. Video game companies could use the contact lenses to completely immerse players in a virtual world without restricting their range of motion. And for communications, people on the go could surf the Internet on a midair virtual display screen that only they would be able to see.
