While Google works to bring a polished Glass device to market, wearables startup Innovega is taking head-mounted displays a step further: contact lenses that interact with full HD glasses.
The next step after Google Glass high-tech specs could be contact lenses with cameras in them to take pictures when you blink and to help the blind across the road.
A pair of newfangled contact lenses, a small projector attached to a pair of lightweight eyeglasses, and -- poof -- welcome to full-blown augmented reality.
DARPA orders prototypes of Innovega's iOptik displays that use special contact lenses so a person can focus both on images shown on the lenses and far-away objects for augmented reality.
Start-ups backed by the National Science Foundation will be showing off a wide range of technologies, including virtual reality contact lenses, robot butlers, and flexible displays.
