An electronically generated display of data superimposed on a user's field of view.
A display technology that superimposes images onto the inside of the windshield to enable drivers to view the information while keeping their eyes on the road. Heads-up displays (HUDs) are also used in goggles and helmets.Initially used in military aircraft to display avionics and instrument readings as well as gunsights in front of the pilot, heads-up displays migrated to commercial aircraft and later to automobiles. Passenger car systems display vehicle speed and objects detected in a collision avoidance system, such as a deer crossing the road ahead.Heads-Up vs. Head-MountedThe terms heads-up display and head-mounted display are often used synonymously. Technically, however, heads-up means that the display is transparent, and the viewer can see through it. See head-mounted display and automotive systems.
A variant of head-up display.
