This time, it may be for real
Virtual reality, in a manner similar to that of language translation based on artificial intelligence, have both been the technologies of the future for about a generation now. But, this time around the architects have some powerful components to build with, such as the "Ergonomic Head Mounted Display Device And Optical System" (which makes me think of Google Glass), that you mention. But will we first see virtual reality with mobile devices? I doubt it. Think of how much bandwidth a two dimensional video transmission requires, and then extrapolate to what the third dimension will call for. Maybe the first application will be gaming, or perhaps a simulation where soldiers or police officers can practice dangerous moves in complete safety, or perhaps surgeons can do dry runs of difficult operations.
