There is no camera to creep people out, no button to push, no gesture area to swipe, no glowing LCD screen, no weird arm floating in front of the lens, no speaker, and no microphone (for now).

From the outside, the Vaunt glasses look just like eyeglasses. When you’re wearing them, you see a stream of information on what looks like a screen — but it’s actually being projected onto your retina.

The prototypes I wore in December also felt virtually indistinguishable from regular glasses. They come in several styles, work with prescriptions, and can be worn comfortably all day. Apart from a tiny red glimmer that’s occasionally visible on the right lens, people around you might not even know you’re wearing smart glasses.
