Safe Eyes Save Lives: How Bosch Engineers Are Innovating The 95-Year-Old Sun Visor

Bosch Engineers Innovate 95-Year-Old Sun Visor

Bosch's technology utilizes intelligent algorithms to intuitively block the sun's glare.

Bosch is rethinking driver safety and comfort, bringing one of the most overlooked interior components into the spotlight, the sun visor. The sun causes twice as many car accidents as any other weather-related condition due to temporary blindness. The National Highway Traffic Safety Administration reports thousands sun glare-related car accidents each year, and another study indicates the risk of a car crash is 16 percent higher during bright sunlight than normal weather. The traditional sun visor is not equipped to adequately address this safety concern. At best, it blocks some of the sun from your eyes but along with it, some of your view is blocked as well.

Bosch is offering a solution with the revolutionary Virtual Visor, a transparent LCD and intuitive camera, which replaces the traditional vehicle sun visor completely. As the first reimagined visor in nearly a century, Bosch’s technology utilizes intelligent algorithms to intuitively block the sun’s glare and not the view of the road ahead.

“For most drivers around the world, the visor component as we know it is not enough to avoid hazardous sun glare – especially at dawn and dusk when the sun can greatly decrease drivers’ vision,” said Dr. Steffen Berns, president of Bosch Car Multimedia. “Some of the simplest innovations make the greatest impact, and Virtual Visor changes the way drivers see the road.”

The Virtual Visor, which was honored as a Best of Innovation in the CES 2020 Innovation Awards, will debut at CES 2020 in Las Vegas. The Virtual Visor was also named as an honoree in the awards competition, which recognizes products across 28 categories. Virtual Visor received the Best of Innovation for the In-Vehicle Entertainment & Safety category, as it received the highest ratings from a panel of judges that includes designers, engineers and members of the tech media.

A sun visor fit for the future

Virtual Visor links an LCD panel with a driver or occupant-monitoring camera to track the sun’s casted shadow on the driver’s face. The system uses artificial intelligence to locate the driver within the image from the driver-facing camera. It also utilizes AI to determine the landmarks on the face ‒ including where the eyes, nose and mouth are located ‒ so that it can identify shadows on the face. The algorithm analyzes the driver’s view, darkening only the section of the display through which light hits the driver’s eyes. The rest of the display remains transparent, no longer obscuring a large section of the driver’s field of vision.

“We discovered early in the development that users adjust their traditional sun visors to always cast a shadow on their own eyes,” said Jason Zink, technical expert for Bosch in North America and one of the co-creators of the Virtual Visor. “This realization was profound in helping simplify the product concept and fuel the design of the technology.”

The creative use of liquid crystal technology to block a specific light source decreases dangerous sun glare, driver discomfort and accident risk; it also increases driver visibility, comfort and safety.

Innovation from the recycling bin

From the original ideation and concept phase to testing and prototyping, Virtual Visor is a bottom-up solution made possible through the innovation culture established at Bosch. Employees are encouraged to apply lean startup methodologies to confirm customer benefits, market potential and feasibility for new ideas, which are then validated by peers and approved for development.

“We’ve built a culture around empowering our associates by putting them in the driver’s seat,” said Mike Mansuetti, president of Bosch in North America. The Virtual Visor was developed by a team in North America as part of Bosch internal innovation activities. “As a leading global technology provider, we understand that innovation can come from any level of an organization, and we want to see that grow.”
