Posted by EfrenProvost on March 2nd, 2020

If you are thinking of changing cars and have already begun to look at the proposals of the different brands, it is more than likely that you have encountered the HUD as one of the star safety features in some of the best cars of 2020. We tell you All you need to know about the HUD or Head-up display

The systems Head-up display have become popular in the automotive industry for being one of the safest ways to display all the information the driver needs, without having to look away from the road.

Parameters such as speed, GPS route indications or road speed limits are some of the data you need to know while driving and consulting them may mean having to take your eyes off the road to see that information in the instrument cluster

Yes, it may seem that only a second has elapsed since you look away from the road to check the speed or look at the indications on the GPS screen, but it is enough time (and space) for an unforeseen appearance on the road and An accident may happen.Visit here: Vizr Review for more information.

Although its implementation in the car industry is relatively recent, we must go back more than 70 years ago to find the origin of this technology. We tell you all about the Head-up Display and how it works

What is head-up display in cars

Literally, Head-up display or its acronym HUD could be translated as a raised Car HUD display. That is, a screen with which you do not need to look away from the road to know all the relevant information for driving.

This system projects the information on the speed of the vehicle, the speed limitation or the GPS indications among other information, directly on the driver's field of vision.

Like many other inventions that are currently common in cars, the Head-up display was developed in 1950 for fighter jets. That way, the pilot could keep his head up (hence his name), and look at his target while controlling the relevant information of his apparatus reflected on the dome of his plane's cabin or on a viewfinder located in the helmet.

The HUB systems for cars are based on a series of mirrors that combine to project the information to the eye level of the driver, so you can see the information without this interferes with vision while driving.

The first cars to mount a Car HUD display left the General Motors factories in 1988. It was a very rudimentary system that has little to do with the current ones, capable of projecting any type of full color image on the front windshield. However, manufacturers tend to simplify the icons and colors of the images that are projected to facilitate reading the information and not distract the driver.

With a simple adaptation of the source of information, images and symbols could be projected in virtual reality (or mixed reality) to make the GPS indications more graphical and understandable or to show more strikingly important warnings or warnings for the driver.

The appearance of a pedestrian or animal on the road, alert about a dangerous crossing, warn of the presence of a vehicle in a blind spot or any other unforeseen that the car's sensors have been able to detect even before the driver himself, may be some of the assumptions that a virtual reality system can show projected in the eyes of the driver.
