Online retailer Amazon has patented a wristband that can monitor the hand movements of its warehouse employees and direct them to items using small vibrations.
The patents, which were filed in 2016, outline Amazon’s vision for an inventory management system that uses wristbands to track workers’ performance and help them locate products in vast warehouses.
Called the Wristband Haptic Feedback System, the series of patents shows a system where employees are guided to “item bins” by tracking hand movements in real time using ultrasound technology.
Messages are then relayed to the employee using small vibrations emitted from the wristband’s bracket. If their hand moves away from a product, a vibration lets them know they are going in the wrong direction.
