Soon, you can control a computer screen with just your eyes. Eyefluence, a Silicon Valley-based startup, is working on a technology for hands-free navigation using augmented reality glasses. The glasses are equipped with cameras that can assess where you’re looking at any given time and users can click on icons with a glance.

“The technology moves as fast as you can think,” says Jim Marggraff, founder and CEO. He adds that unlike some of the other eye-tracking technology, Eyefluence works “without winking and without waiting.”

Eyefluence claims they have the first user interface based on the “eye-brain connection.”Marggraff says there will be both consumer and commercial applications for the glasses. He estimates that there are 40 million “deskless workers” and sees use cases for everything from construction to a hospital operating room.
