A HUD is just a display you can look at while keeping your focus on something else. My car has that, it has no relation to the outside world, it’s just a display.
With AR the information presented is placed within the world around you. Using a camera and motion tracking, it can place stuff in relation to real stuff around you. Think Pokemon-Go.
How would AR ever work without a camera? One implies the other?
Ever seen a jet fighters HUD?
A HUD and AR are something different tho.
