Its completely different like @33-DFTC said. I have programmed for this, its not very powerful, no where near what a PC can push out graphics-wise. Everything has to be created with low polygon counts, and even then there are huge limitations, you cannot render black (black = transparent), the view itself doesnt fully occlude the world, you can always see the world and the field of view is maybe 45 degrees. It's a great piece of tech, and I love it, but AR is not the same as VR and will forever by different.
