Basics

A software that uses the 6DOF Tracking, and Object Recognition in the AR Headset, as well as a downloaded instruction set for whatever task the user is doing (these are selected from the home screen/menu)
It then sees what parts you have, what you have completed, and use this to determine what the next step is, and overlay this over the world in front of you.
It also has a Maintenance mode for smaller devices (like maintaining a powercube), or things like industrial pipe networks, and such
May also overlay info from cameras such as an IR camera, a Near IR camera, a Zoom Camera/Microscope, etc.
