Abstract
A personal remote control device exchanges electromagnetic transmissions with an elevator system, each transmission including the identification number of the device, whereby requests for elevator service made by means of the device are unique to that device, and requests can be made by the device to cancel or change any request for elevator service which has previously been made. The remote control device may either be verbal, communicating with the user by means of speech synthesis and voice recognition, or the device may utilize switches, displays or other mechanisms for interaction with the user.
