HUD (computer gaming)


In video gaming, the HUD (head-up display) or Status Bar is the method by which information is visually relayed 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 main character's health, items, and an indication of game progression (such as score or level).

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.

Typically this information is represented numerically, with the health level being a number from 0–100 (percent): 100 representing full health and 0 representing empty, no health or death. However, many other methods of visual representation can be used. For instance, certain games employ a "health bar" which empties as the player becomes hurt such as Tekken, Street Fighter, and many others.

Armour levels are also commonly monitored, either through a separate readout, or as part of the health system. For example, Halo uses one recharging shield bar, acting as the health level. When this is depleted the player can only take a few more hits before his or her death. The same goes in Destroy All Humans!, but in the form of Crypto's shields. Traditionally, games used lives to represent health. Every time the main character was injured he would lose one of his limited lives. Another way to display the life in the HUD is demonstrated in Gears of War, where the characters life is displayed only when he is taking damage, in which case a red cog known as the Crimson Omen appears in the center of the screen. The more visible the Crimson Omen is, the more damage the player has sustained and the closer he is to death. This health system is known as the 'Red Ring' system.
