With your description someone might just think what you see with a Military jet HUD or Google Glass. Saying "overlay" doesn't tell you anything about depth.
A HUD is AR, some HUDs are just more impressive than others. When you are talking about the difference between printers and monitors, the function of either is so different that it doesn't make sense to describe SVGA and XGA monitors separately.
I'd say the media also has a responsibility to broaden the scope of what the readers understand...
