ABSTRACT:
An elevator installation includes an elevator car moved in an elevator shaft between floors in a building. A shaft door for closing the elevator shaft is arranged at each floor. A method for representing information on the shaft doors makes possible a qualitatively high-grade projection of an image on the shaft door. The shaft doors are formed to be at least partly transparent, wherein a projector is arranged in the elevator shaft and projects an image onto the side of the shaft door facing the elevator shaft.
