Looks like it could be the same person, but wouldn't that make more sense? If it's different people then you're not just changing one aspect, the glasses in this case. The worker presumably has to do the same work many times. So he isn't doing the work in the video for the first time regardless. It's something he does regularly. They could do the work with glasses a couple of times and compare it with non-glass work times. I think this is (as in the video) is the best A/B test way.

If the worker did the Glass test after he did the non-Glass test, his productivity/efficiency increase could be attributed to memory and not just Glass.

  Yeah. Hopefully they would do it multiple times. To not have memory be much of a factor.

    This is aviation work, you always always always check the work you are doing with the manual. One mistake could be someone's life. The entire aviation industry is checklist and procedure driven.

      They even have a specialized English dialect called simplified technical English to help eliminate confusion.

        Have they done any studies on the benefits of using the simplified language vs the time investment it takes to produce the manuals to spec? I'd imagine most of the gain comes from companies with a high number of ESL workers - but it sounds like it may be a tool that a bureaucratic, control obsessed, management culture likes but is largely just busy work parading as productivity gains. It could also make the technical manual writers lazy or use less editing because they lean on the language instead of investing real thought into making their communication effective and easy to understand. As machine translation of english continues to improve, I'm curious how useful it will be. And the feature of "Reducing ambiguity" (according to Wikipedia) is something that can be solved in many different ways without having to invent a whole new simplified language subset for all communication. Either way that's an interesting example of how serious they take this stuff.

        I'm not sure. I don't work in aviation, but you can produce much better documentation by following at least the spirit of this vs. the specific grammars and vocabulary. Engineers and IT people are often not very strong in writing ability, and there are many non-native speakers in technology. I've seen situations where "Cute" documentation with TV references (infrastructure placement was captured by types of disney vs. looney tunes characters) and lots of implied context. Having a style guide that forces simplicity can be a high value.
