Head-up display

A head-up display, or heads-up display, also known as a HUD (/hʌd/) or head-up guidance system (HGS) is a transparent display that shows information without users needing to change their view. The name comes from a pilot being able to see information with the head "up" looking forward and not looking down. A HUD also helps a pilot's eyes since they do not need to refocus how they see.

HUDs were first used for military aircraft. Now they are in commercial aircraft, automobiles, and in used in other products.
