How does D-Lab create “Processed” calibration planes?

A calibration plane is automatically created when you modify the calibration for the first time (Manual Calibration). It displays a message that the original calibration plane cannot be modified, and creates a plane with the name Processed_—-. Further changes in calibration are saved to this plane unless a different one (excluding Original) is selected from the drop-down. It is also possible to manually create a new calibration plane within this window. The eye tracking video shows the gaze point according to the calibration plane that is selected in the drop-down. This can be different from the calibration plane that the AOI was defined in.
