A call-giving device, an elevator system and a computer program product are provided to implement the aforementioned method.

## Background
FIELD OF THE INVENTION
The invention relates to elevator systems applicable to the transportation of people and/or of freight. More particularly the invention relates to the giving of destination calls in an elevator system.
BACKGROUND OF THE INVENTION
Passengers using elevators can generally give calls to elevators either in an elevator car and/or in an elevator lobby. Elevator lobbies are typically provided with up/down pushbuttons, by means of which a passenger can order an elevator to the call floor and simultaneously indicate his/her travel direction. After the elevator has arrived at the call-giving floor, the passenger moves into the elevator car and indicates his/her destination floor with the pushbuttons of the car panel in the elevator car. To a constantly increasing extent so-called destination call systems are used in high-rise buildings, in which systems a passenger indicates his/her destination floor already before going into the elevator car. For giving destination calls a passenger uses a destination call-giving device. A destination call-giving device is generally provided with a so-called decimal numeric keypad and a display means. If a passenger is going e.g. to floor 24, he/she keys into the decimal numeric keypad first the number 2 and then the number 4. The destination operating panel sends the information about the call-giving floor and about the aforementioned floor 24 to the control system of the elevator system. When the call-giving device is portable, or when the system does not otherwise know from which floor a call comes, a destination call must include information about the departure floor. After it has received a destination call the control system of the elevator system allocates the optimal elevator for the use of the passenger and transmits information about this to the call-giving device, on which appears e.g. the text “Elevator B”.
In this way the elevator system identifies to the user in response to a destination call the elevator allocated to him/her. One problem is that selection of the floors by entering a number at a time requires a lot of keying activity, and the selection is for this reason slow. More particularly, if a passenger should select both the departure floor and the destination floor, a selection arranged with conventional methods would be extremely slow. Another problem is that when entering floors with a number of key sequences, incorrect keying easily occurs. For rectifying incorrect keying, the occurrence of an error must be indicated and the keying in must be performed again. This slows down use of the system even more. Yet another problem is that solutions according to prior art do not enable rapid floor selection in a building having selectable floors with an identifier string that comprises three-digit floor numbers. Yet another problem is that for a selection in solutions according to prior art a large number of icons, pushbuttons, et cetera, must be presented to a user. Thus, the solutions are not well suited to call-giving devices in which the size of the display is small.
SUMMARY OF THE INVENTION
The aim of the present invention is to solve the aforementioned problems of prior-art solutions as well as the problems disclosed in the description of the invention hereinafter. More particularly, the aim is to improve the call-giving of an elevator system. Among other things, some embodiments are presented where the giving of a destination call, and more particularly the selection of a departure floor and destination floor belonging to it, is fast and simple to perform. Among other things, some embodiments are presented where the giving of a destination call can be performed quickly and simply with a portable destination call-giving device. Among other things, some embodiments are presented where the giving of a destination call can be performed with a destination call-giving device provided with a small-sized touch-sensitive display.

For processing the touch signal and for executing program commands the processing unit 2 comprises, in addition to a processor P and a memory, connected to the processor an input I1 from the control system of the elevator system, and an input 12 from the touch-sensitive display, and an output O1 to the control system of the elevator system, and an output O2 to the touch-sensitive display. Each of the aforementioned inputs and outputs is preferably able to transmit an electrical signal. Some of these signals can be wireless. For example, the aforementioned output O1 to the control system of the elevator system can comprise a transmitter, such as e.g. an antenna, for transmitting a wireless signal to the control system 11 of the elevator system 10. This is advantageous e.g. when the destination call-giving device is portable. Correspondingly the input I1 from the control system of the elevator system can comprise a receiver, such as e.g. an antenna, for receiving a wireless signal. The input I1 and the output O1 can use a shared antenna.
As has been stated above, the invention is suited for utilization in connection with a portable destination call-giving device. However, the invention is also suited for use in connection with other types of destination call-giving devices, e.g. in connection with destination call-giving devices installed in apartments or in other spaces.
The information identifying an elevator car to be presented on the touch-sensitive display can be any information whatsoever that enables identification of the allocated elevator. This information can be e.g. identification data of an elevator. An elevator car having an identifier B can in this case be identified e.g. with the text “Elevator B”.
It is obvious to the person skilled in the art that in developing the technology the basic concept of the invention can be implemented in many different ways. The invention and the embodiments of it are not therefore limited to the examples described above, but instead they may be varied within the scope of the claims.
