High-tech specs aren't as common in the wild now that Google has gone back to the drawing board on Glass, but one German city might soon have a lot more "Glasshole" sightings thanks to Volkswagen.

The car maker this week announced that it has adopted 3D smart glasses as standard equipment for all its plant logistics personnel in Wolfsburg, Germany following a three-month pilot of the technology. The specs look a lot like Google Glass, but VW didn't specify a manufacturer.

VW said it's hoping the glasses will ultimately improve process security at the plant. Employees can automatically receive information they need to do their job, such as storage locations or part numbers, directly in their field of vision using simple touch and voice controls. This allows employees to have both of their hands free while they're working.

Plus, the camera in the glasses also serves as a barcode reader, which can help employees verify the parts they need. Barcodes of parts that have been correctly removed from storage are shown in green and incorrectly removed ones are in red.

"Digitalization is becoming increasingly important in production," Reinhard de Vries, head of plant logistics at the Wolfsburg plant, said in a statement. "The 3D smart glasses take cooperation between humans and systems to a new level."

VW said it's "gradually" introducing the device to its plant logistics personnel, who can pass on using it if they prefer to keep doing their job the old way. At this point, some 30 employees in areas such as windshields and driveshafts are using the smart glasses, and VW said it eventually plans to expand the technology to other departments, plans, and brands across the company.

Meanwhile, VW isn't the only car maker adopting wearables. Volvo recently teamed up with Microsoft to test out the use of HoloLens in car showrooms, which might eventually let customers virtually customize the car of their choice.
