Another powerful example of how AR will change the world. Telementoring is one of the biggest markets for AR developers. The Microsoft HoloLens, for example, is marketing their hardware towards the ability to connect individuals in remote locations to work on a task together while reducing context switching from the real world task and the remote aid. Imagine being able to get a subject matter expert to assist you with your task from anywhere in the world while feeling like they are just looking over your shoulder (or better yet through your eyes). AR can and will redefine the concept of distance learning. 

An augmented reality based technology designed to assist military surgeons to complete vital procedures on the battlefield might just bring this type of technology into the hands of the Military to help save lives in the battlefield.
