I think, especially education and medicine are currently among the most important use cases for AR. The possibility, to use convincing visual demonstration for teaching, can be quite amazing - just imagine how many boring classes we have slept during our school days - maybe, this could have been prevented! :D
And medicine because of the obvious reasons, you already pointed out. If you are able to perfom highly skilled tasks in an augmented reality, it's not unlikely, you will do well in a realistic scenario as well.
Thanks for your efforts :)
Yeah, this technology is really useful especially in education :) Makes me somehow envious of some students today!
