Agreed. For training purposes this software could be integrated in to the AR you describe so the user could get immediate feedback on the quality of their work without an instructor. To me the holy grail of AR would be expert level overlays for construction or repair jobs. If I could wear AR glasses and see part removal order, torque specs, and reassembly order I could do any mechanical repair job, provided I have the tools.
