A machine system includes monitor devices each having a camera, the monitor devices distributed over a physical area; layout logic forms images from the cameras of the monitor devices into a scene layout for the area; user interface logic receives training signals from sensors directed to a person physically present in the area and to correlate those signals to subareas of the layout; and analytical logic analyzes the layout and training signals to ascertain subareas of the area at which the monitor devices should focus machine sensor and processing resources.
