head-up display
MediumTechnical, Formal
Definition
Meaning
A transparent display that presents data (like speed or navigation) within the user's normal line of sight, typically on a vehicle's windshield or a pilot's visor, so they don't need to look away from the road or sky.
Any transparent interface technology that projects information directly into the user's field of vision to maintain situational awareness, now also used metaphorically in business/tech to describe unobtrusive information presentation.

Frequently Asked Questions
For the transparent display technology, the correct term is the hyphenated 'head-up display'. 'Heads-up' (with an 's') is an informal noun or exclamation meaning an advance warning or alert.
HUD is the standard acronym for Head-Up Display.
No. While aviation and automotive are primary applications, HUD technology is also used in military helmets, some industrial settings, and is a core component of augmented reality (AR) glasses and systems.
The primary benefit is improved situational awareness and safety. By keeping crucial information in the user's line of sight, it reduces the need to divert attention away from the primary task (e.g., looking at the road or an enemy aircraft).
