While many planes have displays on-board which can display similar information, the ability to shrink the technology into glasses and merge the information with a pilot's real-world view is an innovation that could potentially stop disasters./ u& u1 I' @* i, Q& M& ^, y

By using these markers and an in-built gyroscope, similar to the one found in recent smartphones, the glasses can work out the pilot's perspective and overlay the visual layout as well as airspeed, altitude and orientation, on top.
