>A field technician will have minimal benefit from a heads up targeting display. I can think of a lot of scenarios where AR would be a great benefit. For example, imagine an electrician running wires through a commercial building and having the wiring path displayed for him. No digging through documentation, measuring, and marking necessary to get the job done. Or imagine fire fighters with AR heads-up displays getting routing information inside building that is smoky and difficult to traverse.
