1. A computerized system for assigning items to pickers, comprising:
at least one processor;
at least one IR sensor; and
at least one non transitory storage medium comprising instructions that, when executed by the at least one processor, cause the at least one processor to perform steps comprising:
inserting a purchased item into a position of a data structure;
iteratively, for items in the data structure:
receiving, by the at least one IR sensor, IR signals from user devices;
determining a plurality of picker physical locations corresponding to locations of user devices of pickers based on the received IR signals;
calculating a plurality of distances between an item physical location and picker physical locations among the plurality of picker physical locations;
assigning a first unassigned item by:
identifying a closest picker corresponding to a shortest distance of the plurality of distances;
sending information to the user device of the identified picker for display;
receiving an indication that a new picker exists; and
iteratively, for each region of a plurality of regions of a facility:
determining a ratio of number of items in the ordered data structure located in the region to a number of pickers located in the region;
selecting an initializing item located in a region having a highest ratio; and
sending information to a user device of the new picker for display.
