1. A confirmation system for a cubby system of an order fulfilment facility, comprising:
a plurality of touchless confirmation sensors, wherein a selected touchless confirmation sensor is coupled at each of a plurality of cubbies of the cubby system, each of said touchless confirmation sensors being communicatively coupled with a workflow control system, with each said touchless confirmation sensor configured to recognize a plurality of physical gestures from an operator acknowledging that an operation has been successfully completed by repeatedly measuring distances to the operator to track movement of the physical gesture; and
wherein each touchless confirmation sensor comprises a pair of time of flight sensors with each time of flight sensor configured to repeatedly measure distances to the operator to recognize the physical gesture and, upon recognition of the physical gesture, said touchless confirmation sensor is operable to communicate a completion signal to the workflow control system.
