Yes, that's what I meant. Any productivity gains from a HUD are likely to be in high skill/high information tasks and the article states that so far they were modest.
To be fair, there might be some more productivity gains lurking around the corner if augmented reality allows a tighter integration of each process in the factory line.
Any time lost involving searching anything in the factory floor could be reduced with augmented reality by peppering the world with "quest markers".
Besides the 10% gain on searching which parts of the engine you're supposed to either screw in or unscrew out, there might be a gain when searching your wrench, when searching Joe, when trying to find out where exactly the new parts are and so on.
