Amazon has unveiled a prototype of artificial intelligence-powered smart glasses designed to be used by its delivery drivers.
The "Amelia" glasses include a camera and built-in display, and pairs with a waistcoat with a button drivers can press to take photos of deliveries.
"We're testing it at a number of locations with over a dozen delivery service partners and hundreds of drivers across the country," said Beryl Tomay, Amazon's vice president of Transportation, at a launch event in Silicon Valley.
Amazon is the latest US tech giant to enter an increasingly crowded field of firms experimenting with wearables, but for now it is a product meant for drivers, not customers.
