> Camera pass through isn't AR, the same way a security camera isn't AR just because you could potentially view it on a VR HMD.
I would suggest that this is a very modern interpretation. Pokemon go is an "AR" game, even though its camera-mediated. Wayfair has an "AR" furniture viewer, apple has "AR" feature to view the new mac mini: https://www.apple.com/mac-mini/ (search for AR)
as I said, its hazy, and its only now that laser/waveguide see through displays are possible that we can have real-world overlays.
