10. A non-transitory computer readable storage device storing a program of instructions executable by a machine to perform a method for touch-free operation of an ablator workstation by an associated user, comprising: detecting an initial location and a subsequent location of a body part of the associated user; receiving the detected initial location and the detected subsequent location of the body part, deducing a gesture based on the detected initial location and the detected subsequent location, validating the gesture based on a physical characteristic of the gesture, predicting a location of a subsequent user movement location based on an initial user movement location, authorizing the gesture as being from the associated user when the subsequent user movement location is within the predicted location, authorizing the gesture as being from the associated user based on facial recognition when the subsequent user movement location is outside the predicted location, and causing the ablator workstation to perform an ablator task after the gesture is validated and authorized.
