Abstract
An elevator target floor registration unit, which displays an estimated amount of time until an assigned elevator car arrives, reduces feelings of uneasiness. Various target floor registration units by which a user may register a target floor are installed on respective floors of a building. The target floor registration units are connected to an elevator controller via an interface. The elevator controller: (a) assigns a most suitable elevator car corresponding to a user's target floor registered using the target floor registration unit; (b) computes an expected waiting time for the elevator assigned to arrive at the floor of the aforementioned registration; and (c) sends said pieces of information on the elevator assignment and the expected waiting time to aforementioned target floor registration unit in order to display them.
