Abstract
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.
