Boeing have been pioneering research into the use of Augmented Reality (AR) in the aerospace industry.

There is a wealth of information online with instructions, videos, step-by-step tutorials available to help people with maintenance and repair.
This work is still under development and as aircraft need to be built to exacting standards, it will not be used commercially until proven to be reliable. However, coupled with Google Cardboard or similar such commercial versions, there is potential in this technology.
