Interesting discussion of augmented reality that I think makes some useful distinctions, including this:
"Type I Augmented Reality (AR1), whereby the artificial imagery is layered over the background from the personal POV in real-time;
and
Type II Augmented Reality (AR2), whereby the artificial imagery is layered over the background from an impersonal POV or not in real-time."
From the same author: some interesting remarks on learning styles and what may be the most narrowly focused joke in the world.
