Google was granted a patent earlier today for a system that would allow a head mounted display like Google Glass to use holograms. The patent reveals a lot of information about Google’s quest to bring augmented reality to Google Glass and future products, in a manner that’s very similar to what Microsoft is already doing with HoloLens. It’s important to note that this is just a parent, one that was filed well over a year ago, so there’s no guarantee that it’ll hit the market anytime soon, assuming it ever does.
