1. A system for touch-free operation of an ablator workstation by an associated user, comprising: a depth sensor configured to detect an initial location and a subsequent location of a body part of the associated user; and a processor with a memory device, wherein the memory device is configured to store instructions that, when executed by the processor, cause the processor to: receive the detected initial location and the detected subsequent location of the body part, deduce a gesture based on the detected initial location and the detected subsequent location, validate the gesture based on a physical characteristic of the gesture, predict a location of a subsequent user movement location based on an initial user movement location, authorize the gesture as being from the associated user when the subsequent user movement location is within the predicted location, when the subsequent user movement location is outside the predicted location, authorize the gesture as being from the associated user based on facial recognition detected by the depth sensor, and cause the ablator workstation to perform an ablator task after the gesture is validated and authorized.
