If one were to put that in plain English, Google is basically toying around with the idea of transparent displays, which would definitely signal a next generation application for Project Glass. It seems that this patent application talked about a specially designed “diffraction grating” that is placed on an “optical substrate” (which is actually the real glasses glass). The “diffraction grating” will sport several elements, where some of it will allow undisturbed ambient light for you to have a view of all that is around you, while other elements work to reflect and focus computer generated images that is coming in from your Glass frame. Sure sounds like a dream to own, no? Let us hope that the next generation Google Glass too, will have a decent battery life to go along with it.
