An elevator operating device for a floor comprises a touch-sensitive screen. Call symbols are displayed on a user interface, one of which has to be touched in order to input a character stored for this call symbol. In order to enter a two-digit destination floor, the passenger leaves their finger on the touch surface after inputting a first character, whereby the elevator operating device recognizes that the passenger has limited vision. The elevator operating device registers a second character if it detects a confirmation action for the second character without recognizing that the finger has been lifted from the touch surface. As long as the finger is touching the touch surface, no destination call is generated; the destination call is only generated when the passenger lifts their finger, thus indicating that the input has been completed.

Operating method for an elevator operating device with a touch-sensitive screen system

An elevator installation has elevator operating devices arranged on floors of a building and communicatively connected to an elevator controller. The elevator operating devices include main operating devices configured for inputting a destination floor desired by a passenger and for outputting travel information, and at least one secondary operating device arranged on one of the floors. The secondary operating device is next to the main operating device on the one floor and is communicatively connected to the elevator controller. The secondary operating device has a touch-sensitive screen system that confirms a destination floor, input by touch, by a tactilely perceptible feedback in order to support a passenger with a physical limitation when inputting a call. The elevator controller determines travel information for the destination floor input on the secondary operating device and communicates this information to the passenger by the main operating device arranged next to the secondary operating device.
