The problem that all car drivers face is the sunshine, which, statistic reports say, is often known to be the cause of traffic accidents.
Sun visors, tinted car windshields, dark, sunglasses, sometimes just can't help but for a few moments, the driver rides “asleep” blinded by a powerful light source …
Those few seconds, when driving, can easily be fatal.
That is why at the recently held CES fair, Boša engineers displayed their vision of the solution, the “sun visor” that continued with the use of waste material from the recycling bin! Let's start in a row. It has been proven that, causing temporary blinding, the sun causes twice as many car accidents as any other weather.
The National Highway Traffic Safety Administration records thousands of sunshine accidents each year, with another study showing that the risk of a car collision is 16 percent higher in bright sunlight than in normal weather conditions. The traditional sun visor is not equipped to adequately address this safety issue.
At best, it will partially protect your eyes from the sun, but will also partially block the field of view.
Bosh has now offered a solution with a revolutionary virtual visor, a transparent LCD and an intuitive camera that completely replaces the traditional sun visor. In the first perfected viewfinder in the last hundred years, this technology uses clever algorithms to intuitively block sun glare, but not the path ahead.
– For most drivers around the world, the visor component we now know is not enough to protect against dangerous sunshine – especially at dawn and dusk when the sun can significantly diminish driver vision – said Dr. Stefan Burns, president of Bosch Car Multimedia – Some of the simplest innovation has the biggest impact, and the virtual visor changes the way drivers see the road. ”
The “Virtual Visor”, which was named Best Innovation at the CES 2020 Innovation Awards, was unveiled at the CES Las Vegas. “Virtual Visor” also received a prize in a competition with products from 28 categories.
“Virtual Visor” received the award for the best innovation in the category of vehicle entertainment and safety systems, as it received the highest jury rating consisting of designers, engineers and technology media professionals.
A “virtual visor” connects the LCD panel to the driver or camera that monitors the driver to monitor the shadow cast by the sun on the driver's face. The system uses artificial intelligence to locate the driver in the image obtained from the camera facing the camera
to the driver. The visor also uses artificial intelligence to determine landmarks on the face – including the position of the eyes, nose and mouth – so that it can recognize shadows on the face.
The algorithm analyzes the field of view of the driver, darkening only the part on the display through which light reaches the driver's eyes. The rest of the display remains transparent, thus no longer obscuring much of the driver's field of view.
“In the early stages of development, we found that users adjust their traditional sun visors so that they always cast a shadow over their eyes,” said Jason Zink, a technical expert at Bosh North America and one of the co-creators of the virtual visor. – This was key to simplifying the product concept and fostering technology design. ”
The creative application of liquid crystal technology to block certain light sources reduces dangerous glare of the sun, discomfort for drivers and the risk of accidents, while also increasing the visibility, comfort and safety of drivers.
A group of three propulsion systems engineers led by Zink developed the idea for a virtual visor and developed prototypes in their spare time to provide internal funding for the project concept.
“Like many early stage ideas, we also worked with limited capital and resources,” Zink said.
The original prototype we used to first introduce the concept was made from an LCD monitor we found in a recycling bin.
