31 May Understanding Head-Up Display and How It Works

In order to provide a better driving experience to the drivers, safety features are becoming more advanced and generally better. Since the need for safe cars is expanding, car brands are becoming more focused to bring us better cars that are well-equipped to make us feel safe and sound while we drive down the roads.

In the recent years, predicting the dangers on the roads and warning the dangers about them has become the main theme for the latest safety features so that the vehicle is more secure and safer. One safety feature that excels at this theme is Head-Up Display.

Head-Up Display (HUD) is designed to bring the driver information when he will need it the most. It was actually not developed for automobiles and it was only later that it was adapted to the needs of the vehicles and motorists.

It has been around for many years, it was first introduced in 1940s, but it has only been used in the new automobiles in the recent years. It has adapted to the needs of the motorists so well that it has become one of the most appreciated and impressive safety features in new cars.

If you are thinking about purchasing a new car and you are looking for safety features that work then Head-Up Display (HUD) is a safety feature that you must consider. Here is everything about Head-Up Display (HUD) that you should be aware of so that you can take proper advantage of this safety feature.

Head-Up Display (HUD) – What Is It?

Head-Up Display (HUD) is basically a transparent display that is designed to bring you real time data without presenting the need to look away from his view point. The name was given to the technology because the driver can view the information while he is keeping his “head up” and keep looking ahead.

Head-Up Display (HUD) – What Is It?

When the driver needs information, he will not have to look away and down at the instrument panel, but keep his eyes ahead on the road. In this way, the driver will be able to maintain his focus on the road where it is needed instead on a screen that will distract him.

With the help of the Head-Up Display (HUD), the driver can keep his eyes up ahead on the road which will result in better driving and less chances of an accident because the driver was distracted by something else. Since all the important information will be where the driver’s eyes are, there are fewer chances of a mishap.

The History of HUD

The Head-Up Display (HUD) was actually designed for military aviation and the design and concept of HUD has been around since early 1900s. The breakthrough happened in 1942 when the Telecommunications Research Establishment was able to perfect their Head-Up Display (HUD) for a project that focused on refining radar technology for the UK in World War II.

The History of HUD

However, it wasn’t until 1960s when the first modern Head-Up Display (HUD) was drafted by French test-pilot Gilbert Klopfstein. Klopfstein even standardized the symbols for Head-Up Display (HUD) that this designed HUD can be used by pilot all over the world without any hassle.

Now, Head-Up Display (HUD) is used in recreational and commercial aircrafts along with military aviation.

The Use of Head-Up Display (HUD) In Cars

It was in 1988 that we first saw the use of Head-Up Display (HUD) in the automotive industry. It was General Motors that first used this technology in their vehicles. The first ever Head-Up Display (HUD) was found in their Oldsmobile Cutlass Supreme Indy Pace Cars and it was also available as an option on their very popular Cutlass Supreme and Pontiac Grand Prix before it became more widely available.

The Use of Head-Up Display (HUD) In Cars

Another breakthrough happened in 1998 when Chevrolet Corvette (C5) became available with the first ever color Head-Up Display (HUD). After that, Head-Up Display (HUD) became very common and was widely available on many luxury and conventional cars.

The Pioneer Corporation introduced their Head-Up Display (HUD) with a navigation system that presented the information in front of the driver’s view so that he can get real time directions and data for the conditions and the road ahead.

The Two Types of Head-Up Display (HUD)

Right now, we have two major types of Head-Up Display (HUD) that are widely used in the current automobiles. Although both of these types of HUD have the same purpose, there is a little difference is how the information is displayed in front of the driver.

The Two Types of Head-Up Display (HUD)

These two types of Head-Up Display (HUD) are:

  • The first type of Head-Up Display (HUD) uses a treated windshield to display information to the driver. For this, the back of the windshield is treated so that the image of the data is reflected back to the driver as it is projected.
  • The second type of Head-Up Display (HUD) uses a small combiner to display the data to the driver. The combiner can be retracted and is separate from the windshield.

The Head-Up Display (HUD) used in the new vehicles uses Augmented Reality (AR) so that it can bring more advanced system that can work with infrared cameras, GPS and the internet to get the necessary information and project it on the windshield.

The Head-Up Display (HUD) shows multiple information that is useful to the driver. Usually, the modern day Head-Up Display (HUD) will show:

  • Road conditions
  • Speed of the car
  • Turn-by-turn navigation
  • Gear position
  • Gravitational forces
  • Oil temperature
  • Night vision
  • Pathways overlaid on the road
  • Foolproof navigation

Advantages of Head-Up Display (HUD)

Head-Up Display (HUD) is much more than a safety feature that is available in modern cars. It is quickly becoming an integral part of the safety features that are now present in the modern cars, largely because of its many advantages and usefulness.

Some of the core benefits of Head-Up Display (HUD) include:

  • The information is projected right in front of the driver so that the driver is not distracted.
  • The chances of an accident are decreased because the full attention of the driver will be on the road where it is needed the most.
  • The eyes of the driver refocus much quicker because the data is projected and floated 15 feet ahead of the driver.
  • All the information the driver needs is in one place.
  • Head-Up Display (HUD) is often a standard feature in modern cars, so the drivers don’t have to pay separately for this ingenious safety feature.

What’s In The Future of Head-Up Display (HUD)

Although it is very useful and widely available, Head-Up Display (HUD) is still quite a new safety feature. There are only a few car brands that are offering Head-Up Display (HUD) as a standard safety feature, but since most of them are luxury brands, the prices of such cars can be quite expensive.

The Head-Up Display (HUD) is mostly available as an optional feature so if you are interested, you will have to buy it separately. With time, it is expected that the Head-Up Display (HUD) will become more advanced and more widely available to the motorists all over the world so that all can enjoy safety while they drive.
