Virtual Visor: Bosch re-invents humble sun visor

By CARSIFU | 6 January 2020

LAS VEGAS: Bosch has designed a Virtual Visor that could reduce sun glare-related car accidents.

The Bosch solution is a transparent LCD and camera unit, which replaces the traditional vehicle sun visor completely.

As the first re-imagined 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.

Bosch will debut the Virtual Visor at CES 2020 here.

It was honoured as a Best of Innovation in the CES 2020 Innovation Awards.

“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 Bosch Car Multimedia president Dr Steffen Berns.

“Some of the simplest innovations make the greatest impact, and Virtual Visor changes the way drivers see the road.”

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 uses 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 analyses 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.

A study indicates the risk of a car crash is 16 percent higher during bright sunlight than normal weather.

“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 realisation 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.


The Virtual Visor was developed by a team in North America as part of Bosch internal innovation activities.
