Abstract: The disclosure relates to a method for monitoring the travel operation of a person-transporting installation with a monitoring system. The at least one motion-sensing module transmits its motion sequence images to an interaction module and to a hazard analysis module; the motion sequence images are displayed on a screen of the interaction module and, at the same time, in the hazard analysis module the motion sequence images are examined for critical situations with analysis algorithms.

As a result of the warning signal, the interaction module visually and/or acoustically emphasizes the corresponding motion sequence image on the screen and generates a confirmation input field. The travel operation of the person-transporting installation can be influenced based on a manual tapping on the confirmation input field.
