Heads-up display
From Halopedia, the Halo wiki
The Heads Up Display unit, or HUD for short, is a visor mounted display, and is probably the second most useful element in the MJOLNIR Armour, coming just short of their Personal Energy Shields.
The HUD
The Heads-Up Display, or HUD for short, is the main source for information in-game on Halo: Combat Evolved and Halo 2. Sensors augmented into the Spartan's body read vital signs, and display a general wellbeing bar, much like a "Health Bar" in classic video-games. Additionally, it can read the shield level, from the energy signatures it emnates, and displays it in a bar unit. It can also, through sensors placed in the Spartan's glove, read a weapon's ammunition and heat levels.
The Motion Sensor is another important HUD element. It can sense and track movement in a 15 metre radius, and can also tell friend from foe, due to the technology that being has or is operating. Waypoint indicators are an on screen directive that are lain down by an AI. They point out important elements or locations in the Spartan's mission, and are extremely useful, measuring the distance the Spartan is from the objective.
A HUD display are featured in MJOLNIR armor, ODST Body Suits, and even Elite armor.
