I recall talking to a vendor back… 8 years ago? Who had a colleague trialling hololens augmented maintenance. I personally felt it would be amazing to be able to look at equipment, bring up a model and explode it to get a look at (Yeah I know you can do that with a laptop, manufacturing lines have notoriously shitty wifi, not to mention greasy around equipment), assisted procedures were a cool idea too, helps people who may not be super familiar with your specific equipment, like shift or loaner maintenance people.

Over a decade ago, different company, they had a bounty on video procedures, you’d strap a go pro to your head and record something like changing batteries, replacing o-rings, removal of electronics etc for a cash bonus. I’m a text and photo person but I totally see the value in video documentation.

Microsoft had a demo at an ignite conference in 2020 if I recall of hololens doing ar metrics, person looked at things like the elevator and would give them real-time performance data, definitely a gimmick but I still think AR could be useful in an industrial setting.
