Next generation Google Glass may look like your normal sunglasses, come with 2 see-through displays

Google Glass is a nice piece of hardware. And Google put a lot of effort to design it to look as well as it looks.

Still, they have been limited by the technologies available today. And there was nothing else available except for pico projector and some smartly made lenses to project the computer generated images onto your eye. So no matter how much Google tried to make it look good, you still get a bulky piece of glassware that look nothing like normal glasses.

But while that’s the situation today, with Google Glass V1, it doesn’t mean it has to stay that way. In fact, Google is already experimenting with the see-through displays to make the next generation Project Glass look not much different from the ordinary sunglasses you put on on a bright summer day.

Google Glass see-through

The device is described in a patent application for “Near-to-eye display with diffraction grating that bends and focuses light”. It uses a specially designed “diffraction grating” placed on “optical substrate” (that’s the fancy tech talk for your actual glasses glass). That “diffraction grating” has several elements, some of which let through undisturbed ambient light so you can see your surroundings. Other elements reflect and focus computer generated images coming in from your Glass frame, in front of your eyes.

The final effect is virtually the same like you get with current Google Glass, but from a device that looks just like normal glasses would look, without the bulky frame on top of them.

I am not sure how far ahead with this see-through display technology Google is today. After all – it is just a patent app, and the necessary components might not become available for years. But Project Glass itself looked like a far out concept years away from implementation, only a year ago, when Google shared their first videos. And today we already have working devices in happy user hands.

Maybe see-through Google Glass isn’t that far away as well?

    Here’s something that should go into a patent (and someone better credit it to me…

    1) the visor/glass needs to have a stereoscopic camera embedded.

    2) the reason for this is, that Augmented content can be superimposed at correct Z depth and in stereo3D for added realism. (no point seeing a 3d building floating in front of you at the wrong depth)

    3) I prefer the name “Wizer” a visor with augmented intelligence built-in.

    4) Cross-polarizers or “active polarization” to attenuate light dynamically

    Here’s a closeup of the visor from the book: The Dirrogate.
