I see this having a real future in some special cases, but for this price not as a general use tech. I saw a movie where a guy was repairing a ship with some AR (not VR) glasses/eyepiece that was identifying the parts he was looking at and helping with information on what is that, what it does, how to assemble or disassemble etc. Like having the instructions in your hands while having your hands free to work. Voice commands should be included. But creating the app showing the instructions and then loading good models and information in the app is probably the big challenge. I work in manufacturing, there are so many maintenance operations and a limited amount of experts that can do it. With the right price and the right apps and docs, this can make a huge difference.
