Walmart Says To Develop Camera System To Detect And Assist Unhappy Shoppers

Walmart is creating an in-store facial recognition system designed to recognize customers' facial expressions. According to the retailer's patent filing, the technology will use video cameras at store checkout lines to detect signs of anger and dissatisfaction. Upon detection of an “unhappy customer”, the system will alert staff and prompt them to report to the checkout line. Also, the company has filed a patent for using drones to improve customers' in-store experience.
