Understanding Heads Up Displays (HUDs)
One of the most important drivers of safety in your car is keeping your eyes on the road ahead and avoiding
distractions. With modern vehicles awash with screens, heads up displays can help maintain your focus on the road
instead. They project vital information, such as speed, any alerts and navigation information, onto the windscreen
in front of you, as a transparent layer that does not obscure your view of the road.
That means you can see all the information you need for safe driving without shifting your view away from your
surroundings at all.
How does a Heads Up Display Work?
The Heads up Display uses a projector and transparent displays to project the image they generate onto the
windscreen in front of you as the driver. From your perspective, the display appears to float ahead of the vehicle,
and remains clear and bright in both day and night environments.
While this seems very futuristic, you could actually build a similar setup yourself using a Raspberry Pi , and you
can find more about that in our article .
What Cars have Heads Up Displays?
While initially this was technology that we only found on the most expensive luxury vehicles, as with everything, it
has trickled down to more affordable models too, including:
BMW: Models like the 3 Series and 5 Series.
Mercedes-Benz: Featured in the E-Class and S-Class.
Audi: Available in vehicles such as the A4 and Q7.
Mazda: Integrated into models like the Mazda3 and CX-5.
In addition, there are aftermarket options that let you
retrofit HUD technology into your current vehicle.
Conclusion
By letting you focus on the road, a heads up display offers a safer way to see the information you need when
driving. As more vehicles shift to complex touchscreens, it is not surprising that this less distracting, easier to
use technology is gaining in popularity.
