Published on January 30, one of the patents details how the wristbands — through a haptic feedback system — vibrate to steer the wearer's hand in the right direction, thereby ensuring that human workers fulfill more orders. Likewise, the technology is also meant to track products as they move throughout the warehouse.

Amazon, responding to concerns about this additional layer of worker surveillance, issued the following statement:

Accordingly, improved approaches for keeping track of where an inventory item is stored are of interest.”
