A patent entitled "Ultrasonic bracelet and receiver for detecting position in 2 d plane" (Ultrasonic Bracelet and Receiver for Detecting Position in Two Dimensional Surface) was filed by Amazon in March 2016, Things that had been released in September.

In the illustration, the ultrasonic sensor (16) is attached to the four corners of the shelf, and the state of the worker performing the work is drawn in front of it. A bracelet (12) is attached to both wrists of the operator, and ultrasonic waves are emitted from it. It is a device that catches the signal with the four corners ultrasonic sensor (16), calculates the time difference between them, and performs "triangulation" to track the position of the actual operator's hand.

In spite of this system that I could think "tracking to it and monitor it ... ...", this system is said to be "to reduce the worker's burden" on the purpose of this system. In the conventional warehouse system, the worker needs to perform work such as refilling the shelves with goods, picking from picking from the shelf and pushing the button or scanning the barcode, such as an extra incidental to the work It was necessary to do a procedure. This patented technology seems to aim to reduce the burden by reducing those work.

Although advanced automation is progressing in Amazon warehouse, work which has to interpose human hand such as the end part is left behind. Amazon's warehouse "fulfillment center" that operates all over the world is said to exceed 100 in total, and by introducing such a tracking system, waste is generated by "a mountain if dust is piled up" It may be aimed at eliminating and reducing costs.
