Abstract: An exemplary elevator passenger interface device includes a touch screen configured to allow a passenger to indicate a request for elevator service by touching the screen. An assistance button is positioned near the touch screen. A controller is configured to determine a destination requested by a passenger touching the screen. The controller is also configured to determine whether the assistance button has been manipulated and then to determine a destination requested by a passenger from a subsequent manipulation of the assistance button.
