LAS VEGAS — Drivers sometimes block significant parts of their field of vision when using sun visors to try to keep bright light out of their eyes. German auto supplier Robert Bosch's new Virtual Visor technology, a transparent LCD panel and integrated camera visor to replace a traditional vehicle sun visor, shades only the areas of sunlight in the driver's eyes.

The visor, released at CES, uses a single, transparent panel, a driver-monitoring camera and facial detection to track the driver's eyes and block the sun accordingly. Artificial intelligence determines specific features on the driver's face, such as the eyes, nose and mouth, and identifies where shadows from the sun are cast on the face.

"We discovered early in the development that users adjust their traditional sun visors to always cast a shadow on their own eyes," Jason Zink, technical expert for Bosch in North America and a co-creator of the Virtual Visor, said in a statement.

Transparent pixels in the shape of hexagons on the screen allow for digital movement of the shaded areas of the visor to adjust to where the driver's eyes go.

Also at CES, Bosch is showcasing a sensor to let cars "see" three-dimensional views of the road, a technology that works with the company's existing camera and radar products.

Bosch, the world's largest auto supplier, has made a number of announcements related to the company's role in the future of mobility the last few years at CES.

Last year, the supplier introduced a new IoT marketing campaign, coined "Like a Bosch," based on the success the supplier sees in new vehicle technologies. In 2018 , the supplier expanded its crowd-sourced parking service and provided updates on its investment in mapping technology company Here.
