Head-Up Display (HUD) (TL9): This is a 3D video display integrated into glasses or a helmet visor, or designed to be projected onto a windscreen. A HUD can also be printed onto a flat surface. See Using a HUD (below). Many vehicles, suits, sensor goggles, and the like incorporate a HUD at no extra cost, and direct neural interfaces (pp. 48-49) make a HUD unnecessary. If bought separately: $50, neg., uses external power. LC4.
Using A HUD
The Head-Up Display, or HUD (above), is a nearly ubiquitous technology. It displays visual information (text, sensor views, suit or vehicle instrument readouts, a computer screen, targeting crosshairs, a web browser window, a video show, etc.) by projecting it directly onto the wearer’s visor. Any piece of electronic equipment that uses a visual display screen may be connected to a HUD by a cable or a communicator. A HUD also allows hands-free monitoring of devices. A HUD provides +1 to skill rolls when reacting quickly to information is important – maneuvering with a thruster pack, for example. Driving, Piloting, and Free-Fall skill rolls often benefit from a HUD. Many wearable sensor devices and suits have a HUD built-in at no extra cost.
