In video games, the HUD (heads-up display) is the method by which information is visually displayed to the player as part of a game's user interface. It takes its name from the head-up displays used in modern aircraft.
The HUD is frequently used to simultaneously display several pieces of information including the player character's health points, items, and an indication of game progression (such as score or level). A HUD may also include elements to aid a player's navigation in the virtual space, such as a mini-map.
While the information that is displayed on the HUD depends greatly on the game, there are many features that players recognize across many games. Most of them are static onscreen so that they stay visible during gameplay. Common features include:
There are also trends common among genres and platforms. Many online games show player names and a chat text box for talking to the other players. RTS games tend to have complex user interfaces, with context-sensitive panels and a full-overview mini-map with fog of war.
Most types of information can be represented in a variety of ways. A character's health, for instance, may be shown numerically, such as a percentage ranging from 0 to 100, where 100 indicates full health and 0 signifies death. A common alternative is the health bar, which visually depletes as the character takes damage. This method is frequently used in fighting games like Tekken or Street Fighter. Another traditional representation is the use of hearts, as seen in The Legend of Zelda, where each injury causes the player to lose a heart. In some titles, such as Gears of War, health is not constantly visible but instead appears contextually. When the player is injured, a red cog icon emerges on the screen; the more prominent the icon, the greater the damage sustained.
HUDs in games are most commonly static and non-diegetic, meaning the interface is always visible and does not exist within the game world itself. An alternative approach is the dynamic HUD, which only displays relevant information depending on the gameplay context. This reduces on-screen clutter and distractions, which can in turn enhance narrative and spatial immersion. One example is Red Dead Redemption 2, where, while exploring on horseback, the HUD may only show the mini-map and the horseâÂÂs stamina meter when galloping. When the player enters combat, the game will display information related to ammunition along with the meters for player health, player stamina, "Dead Eye" ability, horse stamina and horse health.
A diegetic HUD integrates information directly into the game world, helping maintain the playerâÂÂs suspension of disbelief. For example, in Dead Space, the protagonist's health is displayed along the spine of his suit, making it constantly visible to the player due to the third-person perspective. Some games also use visual cues such as wounds, limping, heavy breathing, or bloodstains to indicate injury, a notable example being Resident Evil 2.
Certain games offer customizable HUDs, allowing players to tailor the interface to their preferences. World of Warcraft is notable for supporting extensive modification through Lua scripting. Similarly, Horizon Zero Dawn enables players to set the display of each element to always appear, show only when relevant, or never display.
In rare cases, games omit the HUD entirely, relying on environmental and auditory cues to convey information. Ico, for instance, features no HUD, complementing its calmer style by avoiding many traditional game-like elements.
Some console video games are able to display an HUD on video game controllers that contain a smaller second screen that accompanies the gameplay on the main display. The Dreamcast, released in 1998, uses a VMU on many games as a HUD. A notable example is Resident Evil 2, ' and ' all using the VMU to show a mini version of the HUD, which displays the protagonists health and ammo. This feature returned with the introduction of the Nintendo Wii U, which uses the Wii U GamePad for some games as a HUD including Mario Kart 8 and Super Smash Bros. for Wii U.
Multi-screen gaming systems, particularly the Nintendo DS and Nintendo 3DS handheld systems, can also assign HUD information to one screen while showing gameplay in another.
Some video games utilize companion apps to display HUD information on a smartphone or tablet. Notable examples include Red Dead Redemption 2 and '/.
Prolonged display (that stays on the screen in a fixed position, remaining static) of HUD elements on certain CRT-based screens may cause permanent damage in the form of burning into the inner coating of the television sets. It is a risk for players who play games with HUD elements for extended periods of time. Plasma TV screens are also at risk, although the effects are usually not as permanent.
