AR won't get you manuals. There will be less AR manuals since they will have to produce both paper and AR. To recognise parts will take pretty good pattern recognition, but possible, what can a phone do now? But the next step will take AI at a fairly high level if it's guiding you through a process. If a camera can look at a motor and 'see' what to do, then just a voice telling you want to do will be close to brilliant and useful now, camera and speakers are easy. True a overlay would be better, but the underline tech is AI, if you can make this AI then no need for AR at this stage, sell it now if it's possible.
