Re: TBH I'd thought they solved this problem decades ago.
I always figured this "augmented reality" stuff would be great for overlaying diagrams of hardware (like engines and gas turbines) on the real hardware
Trouble is that displaying the instructuons over the top of complex parts make them impossible to read.
You either have to set some white background around the text and diagrams, or the user is forced to move to 'look' at some blank wall to read them
