A system for operating machinery in a manufacturing environment including machinery, the system comprising: a sensor system configured to distinguish human skeletal positions from non-human object positions, the sensor system further configured to determine whether one or more humans are present in a predetermined area; and a computer (1310, 1406) configured to: responsive to determining that only the one or more humans are in the predetermined area, determine whether a false positive result has occurred, wherein the false positive comprises a first determination that the one or more humans are present when no human is actually present; and responsive to determining that the false positive result has not occurred, the computer (1310, 1406) take an action selected from the group consisting of issuing an alert, stopping the machinery, or a combination thereof; and wherein the computer (1310, 1406) is further configured to: provide a graphical user interface that presents an outline of a human body with identified points of articulation from which a user selects a plurality of points of articulation to be detected; prior to determining that the false positive has not occurred, use the sensor system to track movement of the plurality of points of articulation of the skeletal positions of the one or more humans to create tracked points of articulation; compare the tracked points of articulation to known sets of points of articulation; and responsive to the tracked points of articulation matching an authorized set of points of articulation corresponding to an authorized movement of the human with respect to the machinery, determine that the false positive result has occurred. a sensor system configured to distinguish human skeletal positions from non-human object positions, the sensor system further configured to determine whether one or more humans are present in a predetermined area;
