    # name: The unique name to assign to the device instance created.
    #   The device is accessed from within the PsychoPy script

    #   variable name as well.

    name: tracker

    # enable: Specifies if the device should be enabled by ioHub and monitored
    #   for events.
    #   True = Enable the device on the ioHub Server Process

        # IMPORTANT: Note that while the gaze position data provided by ioHub
        # will be in the Display's coordinate system, the EyeLink internally
        # always uses a 0,0 pixel_width, pixel_height coordinate system
        # since internally calibration point positions are given as integers,
        # so if the actual display coordinate system was passed to EyeLink,

        # possible target locations during calibration.
        
        # type: sr_research.eyelink.EyeTracker supports the following

        auto_pace: True

        # pacing_speed: The number of sec.msec that a calibration point should
