Have you ever looked out the window during a flight and wondered just what that landmark was? It's not always easy trying to figure out where you are, or what you are looking at. But this new technology could take away all the guesswork!

Zeiss wants to upgrade commercial jets with touch-free holographic Multifunctional Smart Glass systems. This may take the form of windows that display flight information, geographical orientation, and moving maps for commercial plane passengers. 

The German company isn’t restricting its holographic smart glass to airplane cabins, either. They are testing augmented reality HUD cockpit displays that reduce the need for pilots to look away from their surroundings. 

The technology could serve as an invaluable tool during low-visibility situations such as evening flights, fog, and inclement weather. Future uses could also include turning an entire cockpit window into a single, augmented reality HUD display. Doing so may also minimize collision risks, as well as unnecessary holding patterns and flight diversions.
