Introduction to Augmented Reality Windshields
General Motors has filed a patent application that reveals its vision for transforming entire windshields into augmented-reality displays. This technology would transcend the present head-up displays that project information like speed onto the windshield. The patent application, published by the United States Patent and Trademark Office (USPTO) on April 30, after being filed by GM in 2022, outlines a more complex system.
What is Augmented Reality?
Augmented reality encompasses a wide range of imagery that might be projected onto the windshield to offer the driving force greater environmental awareness. However, current hardware has limitations, with a narrow field-of-view range that makes it difficult to display information in the driving force’s peripheral vision.
Benefits of a Wider Field of Vision
A wider field of regard could have several potential advantages, in response to GM. For example, it could possibly be used to alert the driving force to an animal crossing the road before it’s directly in front of the vehicle. Additionally, a wider field of view could allow for a head-up display for use for "primary instruments," which will not be possible with current head-up displays.
How it Works
To address the problem of limited field of view, GM proposes using two image projectors, each geared toward a distinct a part of the windshield. The images from the 2 projectors would mix to create one continuous display from one fringe of the windshield to the opposite.
Comparison to Other Automakers
GM will not be the one company exploring this technology. Nissan’s design boss, Alfonso Albaisa, has stated that the "windshield will probably be your screen" in the long run. Toyota showcased its "Window To The World" augmented reality concept in 2011, and up to date concept cars from Mercedes-Benz and Volkswagen have featured similar displays. Apple also investigated an augmented reality windshield before canceling its electric vehicle project.
Future Plans
While none of the businesses mentioned have announced production plans, BMW has stated that its upcoming Neue Klasse generation of electrical vehicles will feature displays that span the windshield. This suggests that augmented reality windshields may change into a reality within the near future.
Conclusion
The concept of augmented reality windshields has the potential to revolutionize the best way we drive. With the flexibility to display a wide selection of knowledge and imagery, drivers could have greater awareness of their surroundings and improved safety on the road. As technology continues to advance, it can be exciting to see how automakers like GM, Nissan, and BMW bring this vision to life.
