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.
