Be Like Arnold, See Like Arnold

Imagine browsing online, but without a screen. The images and text would just sit suspended in front of you in midair. Mad futuristic vision? Nope.

Researchers at University of Washington in Seattle have developed a very early prototype of contact lenses that could allow the wearer to see a virtual world around him or get simple data, like the odometer reading on their car or driving directions as a heads up display. The effect from the electronic circuit embedded lenses would be sort of like the Terminator's vision. The lenses will use LEDs to generate the images, and though the lenses sit on the surface of the eye, the image would appear to float.

Just one small perk, in addition to ease of stalking and killing your enemies: Anyone who has ever worked on a laptop on an airplane or in a coffee shop should appreciate the privacy implications of the lenses–only you can see your data or images.
