Wrist band haptic feedback system
First Claim
1. An inventory management system, comprising:
- an inventory holder including inventory bins configured to store inventory items;
three fixed radio frequency (RF) antennas transmitting RF interrogation signals and receiving RF response signals generated in response to the RF interrogation signals;
a user-wearable unit configured to be worn in proximity to a user'"'"'s hand, the user-wearable unit including a portable radio frequency (RF) transceiver configured to transmit the RF response signals in response to receiving the RF interrogation signals;
an RF transceiver operatively coupled with the three fixed RF antennas; and
a management module operatively coupled with the RF transceiver and configured to process signals generated by the RF transceiver to;
continuously determine a location of the user-wearable unit in a three-dimensional space; and
monitor performance of an inventory task assigned to the user by continuously comparing the location of the user-wearable unit in the three-dimensional space with one or more locations of the inventory bins in the three-dimensional space to detect an interaction between the user and one of the inventory bins, the inventory task assigned to the user being at least one of retrieving an inventory item from a designated inventory bin or placing an inventory item into the designated inventory bin.

Abstract
Inventory management systems and related methods employ radio frequency based tracking of a worker'"'"'s hands to monitor performance of inventory tasks. An inventory management system includes inventory bins, a user-wearable unit configured to be worn in proximity to a user'"'"'s hand, fixed RF antennas configured to transmit at least one RF interrogation signal and receive at least one RF response signal, a RF transceiver operatively coupled with the fixed RF antennas, and a management module operatively coupled with the RF transceiver. The user-wearable unit includes an RF transceiver configured to transmit RF response signals in response to reception of the at least one RF interrogation signal. The management module is configured to process signals generated by the RF transceiver to track locations of the user-wearable unit and identify an inventory bin based on proximity of the user-wearable unit to the identified inventory bin to monitor performance of an inventory system task.

15. A computer implemented method comprising:
-
transmitting RF interrogation signals from RF antennas; receiving, via the RF antennas, RF response signals from a user-wearable unit worn in proximity to a user'"'"'s hand responsive to the RF interrogation signals; generating arrival time signals indicative of arrival times of the RF response signals at the RF antennas; processing, by a management module, the arrival time signals to continuously track location of the user-wearable unit within a three-dimensional space that includes storage locations configured to store items; identifying, by the management module, one of the storage locations based on proximity of the user-wearable unit relative to the identified storage location; and monitoring performance of a task based on the identified storage location. - View Dependent Claims (16, 17, 18, 19, 20)
