Contact Lenses Could Project Mobile Phone Displays Directly into the Eye

New display may have unusual UI implications ...

"Imagine walking down the street and as your mobile phone rings, the name of the caller suddenly appears floating in the air in front of you. That is one of the possibilities offered by a new contact lens which incorporates electronic circuits which can create a type of heads-up display, right within the eyeball.

Engineers at the University of Washington 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. "This is a very small step toward that goal, but I think it's extremely promising."

There are many possible uses for virtual displays. 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.

The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up.

Ideally, installing or removing the bionic eye would be as easy as popping a contact lens in or out, and once installed the wearer would barely know the gadget was there, Parviz said."    (Continued via cellular-news)    [Usability Resources]
