For pilots of fighter aircraft such systems have existed since the 1940s. In Germany they became known as reflex sights (target devices). Around thirty years later, systems emerged that could be called complex windscreen projectors. A typical feature for a windscreen projector is the second window in the cockpit, on which various information can then be projected. Nowadays the head-up display is by far the most important display in the cockpit. The HUD displays information from a number of sources, such as avionics and radaror weapon systems, all in a compact, manageable form. The pilot has a choice of different modes for the head-up display, which he can choose depending on the respective order or the status of his mission. Each mode supports the pilot with a very specific task, be it e.g. B. in navigation, when using different missiles or during landing.

In the meantime, these systems are also used in the latest civil jet types, e.g. B. Airbus A350 and Boeing 787 . Older aircraft can also be retrofitted with such systems if required.

In the 1980s and 1990s, General Motors in the United States had a black and white head-up display with fixed, non-configurable displays in various car models. B. always had the current speed in view without having to look away from the road. At Nissan there were already individual models, e.g. B. the Nissan 240SX .

From 2001, a color display was used for the first time in the General Motors Corvette . [1]

As the first European manufacturer to launch BMW one of the Automotive Siemens VDO AG developed head-up display in the automotive industry in mass production in the year 2003 featured 5-pack and 6-seater model series on the market [2] in 2005, followed by PSA with the Citroën C6 . In the meantime, automobile manufacturers and automotive suppliers are working on head-up displays with 3D and augmented reality functions. [3]

Head-up displays are offered by various manufacturers. There are also devices for retrofitting; Garmin offers a model that is linked to a smartphone via Bluetooth and projects information onto the windshield using a navigation app. Other manufacturers offer head-up displays for retrofitting, which can read out information via the OBD-II diagnosis of the vehicle and thus show details about speed, engine speed or engine temperature.

Cabinets of older arcade machines often also contain a head-up display, as the center of gravity of the machine moves downwards by moving the heavy picture tube into the base and the machine becomes more stable. Instead of a semi-transparent glass pane, a normal mirror is installed in the player's line of sight. With the introduction of TFT screens in slot machine technology, this application has become rare.

In current computer games , on the other hand, head-up displays generally refer to status indicators that do not belong to the virtual environment, but are statically positioned at the edges of the field of vision. Other computer programs are also increasingly being equipped with head-up displays.
