I examined recently how NUI is described.
One description describes that AR is among NUI. I don’t think so.
Real world seen is already rich and dangerous enough. The AR, for instance with Head Mount Display, adds extra information for seeing, which leads further stress on human sight/brain. AR is practical for those who are used to exposed and manage spiritual tensions such as soldiers. However AR will be an extra stress to most people, until human being get used to it as part of life, and it make time time more than a few generations.
