This generation of AR is going to be like the last generation of VR -- a cool gimmick with great promise of things to come, but not really advanced enough to deliver on that promise. Even the virtualboy was pretty cool at the time, but it took 20 years to get to occulus. If someone can make these things work like they do in the movies then everybody will get one, but the technology doesn't seem to be there yet. I don't understand most of the words in this article, but it sounds like even if the computation equipment is powerful enough to render these images that the hardware to transmit them to the viewer has a lot of limitations.
I used the HoloLens at a demo and it was amazing, but after 3 demos of 5 minutes each over the course of 30 minutes, my eyes felt tired for the next hour. And the limited field of view did detract from the experience.
I've been wanting a heads up display in my glasses for years ever since the first "wearable computing" wave. Eventually it will happen, but all the hardware breakthroughs are so much slower than software.
