The HUD or is known as the ‘Heads Up Display’. This technology has been previously used in aviation since the late 1950s, and was initially used in the military only. During the 1970s, the HUD expanded to commercial aviation. Additionally, during the late 1980s the HUD expanded to cars, although not very popular at the time.
Over the last few years, the HUD has expanded exponentially; it is currently standard in all modern aircraft, space shuttles and as of 2013, it will now be launched in all current cars.
Various car manufacturers had previously tried to incorporate HUDs into the cabin of cars over decades ago, but it had failed.
Consumers were not ready for this type of technology. However, as our knowledge has increased over the years, the device looks promising for motorists.
The benefits of the HUD in our cars
The HUD is situated over the dashboard, just below your external visibility line.
It is very similar to the GPS system that motorists use only not as complex. However, before using the HUD motorists must familiarize themselves with it or it could prove to be another distraction whilst driving.
Basically, the HUD is a small box that sits on your dashboard and projects travel information onto your windscreen without blocking visibility.
The HUD is an extremely useful tool, particularly when driving at night.
The display shows floating road maps, speed limits, your own speed, cruise control, night vision, distances and radar locking with the car in front. It also operates a tachometer and full navigation system. All models of car that are fitted with the HUD technology can vary in cost as not all of them may have the same instruments. As the technology grows there will undoubtedly be some manufacturing competition out there.
BMW has manufactured cameras into their HUDs which can read temporary, permanent and overhead road signs. Should motorists be approaching road works where traffic is temporarily slower, their HUDs will detect and display the approaching hazard.
The future of the HUD is expected to grow; it is also expected to replace onboard audio equipment. Additionally, it is hopeful motorists will be able to use it for calling, emailing and texting, but not whilst driving.
The Heads Up Display
The screen resolutions over the years have improved from 128 x 128 pixels to 640 x 480, 780 x 280 VGA and much more. It is a possibility that the Heads Up Display could replay all other instruments in our car soon.
Today, there are different types of ‘Heads Up Display’ devices available on the market. Some HUDs can be plugged into the OBD socket (onboard diagnostics socket), and some need to be hard wired.
If you choose to buy a ‘Heads Up Display’, prices start from approximately £75.00, usually there are extra accessories also to buy.
The ‘Heads Up Display’ in this picture is a simple HUD; this one is based on projecting images onto the small glass. This glass can flip up and down and should protect the device becoming an attraction for car thieves. The HUD is ideal for motorists who are concerned about the lack of visibility.
Another ‘Heads Up Display’ unit that manufacturers are making, but are not on sale at the moment are a two-part device. One part of the unit is attached to the sunroof, and the other part sits on the dashboard. A laser is transmitted from one unit to the other and information is then reflected onto the window screen.
TIP: Any unit that is not connected to the ECU is limited to giving vehicle operating information.
