Abstract
An elevator call system including an elevator landing door (101) and a call mechanism having a projection mechanism (105a) configured to project at least one image (116, 118) onto a call zone (108) and an image detector (105b) configured to detect the at least one image (116, 118). When the image detector (105b) detects a change in the at least one image (116, 118), the call mechanism is configured to communicate with an elevator control system to request an elevator car to stop at the elevator landing door (101).
