Abstract

The present invention relates to a method and to a computer system arrangement for producing a dialogue between a central computer unit and at least one user unit. The user unit includes at least one display means and a memory means and can be connected to the central computer unit. The central computer unit includes a central memory means in which there is stored a software part, called the dialogue part, which is intended for data processing requested by the user unit. Information concerning the text and/or picture for presentation on the display means is pre-stored in the user unit memory means and separate user units may be of different types. The information transmitted from the central computer unit to the user unit during a dialogue session includes at least one first identifier which corresponds to a message to be transmitted, wherein the first identifier points out a presentation object which corresponds to the message in the user unit memory means. The presentation object presents the message in different forms, according to the type of user unit concerned.

Claims

1. A method for obtaining simplified dialogue between a central computer unit and at least one user unit of a plurality of user units in a computer system arrangement, wherein the user units each include a display means and a memory means and can be connected to the central computer unit, wherein the user units are of different types, and wherein the central computer unit includes a central memory means in which there is stored a software part, referred to as a dialogue part, intended for data processing requested by a said user unit, wherein information relating to text and/or pictures, depending on the user unit type and depending on a chosen type of information display, for presentation on the respective display means is prestored in the memory means of each user unit;

wherein the prestored information is different for the different user unit types, wherein the information transmitted in a dialogue session from the central computer unit to a said user unit includes an identifier which corresponds to a particular message to be transmitted and which identifier is the same for all user units to which that particular message is to be sent irrespective of their type and the chosen type of information display, wherein the identifier points out, in the said user unit'"'"'s memory means, a respective presentation object which corresponds to the message, and wherein the respective presentation object presents the message on the said user unit'"'"'s display means in the respective manner for the said user unit, characterised in that a first local call including the identifier is made in the central computer unit, the purpose of said call being to cause the message to be presented on a display means;

in that the first local call is converted to a non-local call in the central computer unit;

in that the non-local call is converted to a second local call by a said user unit;

in that a picture interpreter in the said user unit identifies a corresponding presentation object in the said user unit'"'"'s memory means by means of the identifier included in the second local call;

in that the presentation object may include a pre-defined program operation which presents the message either as a picture which consists solely of text or as a picture which includes both text and graphics, or as a message which includes a graphic picture and sound illustration, in accordance with the type of user unit concerned;

in that the picture is presented on a display means belonging to the said user unit;

in that a user of the said user unit gives one or more reply data;

in that reply data is transmitted from the said user unit to the central computer unit, which receives this data;

and in that the central computer converts reply data to a format which can be interpreted as a reply to the first local call.

2. A method according to claim 1, characterised in that a plurality of presentation objects are stored in the form of a picture directory in each user unit memory means, each presentation object being addressable by a respective identifier.

3. A method according to claim 1, characterised in that the identifier that is transmitted from the central computer unit to a said user unit is given by the dialogue part of the central computer unit;

in that the identifier is interpreted in an interface part of the said user unit; and

in that the interface part uses the identifier to point-out the corresponding presentation object in the said user unit'"'"'s memory means and present a corresponding message on the said user unit'"'"'s display means.

4. A method according to claim 1, characterised in that reply data is transmitted from the user unit to the central computer unit in the form of identifier-references to read-made reply alternatives.

5. A method according to claim 1, characterized in that the reply on the first local call initiates repetition of the method.

6. A method according to claim 1, characterised in that a further first local call is made and the method is repeated when the reply to the first local call contains a request from the central computer unit for more information from the said user unit.

7. A method according to claim 1, characterised in that the mother tongue presented as picture and/or text information on the display means belonging to a said user unit is chosen individually for each user unit.

8. A method according to claim 7, characterized in that a user of a user unit gives one or more reply data in a chosen mother language and the reply is interpreted in the central computer unit in a mother language which is independent of the chosen mother language.

9. A computer system arrangement for providing a dialogue between a central computer unit and at least one user unit of a plurality of user units, wherein the user units include a display means and a memory means and can be connected to a central computer, wherein the user units are of different types, wherein the central computer unit includes a central memory in which there is stored a software part, referred to as a dialogue part, intended for data processing requested by a said user unit, wherein information relating to text and/or pictures depending on the user unit type and depending on a chosen type of information display, for presentation on the respective display means is stored in the memory means of each user unit, wherein the prestored information is different for different user unit types, wherein a respective interface part in each user unit is intended for communication with the respective user unit memory means and the respective user unit display means and also with the central computer unit, wherein the dialogue part of the central computer unit is intended to disclose a particular message to be presented on a said user unit'"'"'s display means by means of an identifier, which identifier is the same for all user units to which that particular message is to be sent irrespective of their type and the chosen type of information display, wherein the identifier is transmitted to the interface part in the said user unit and points out a presentation object, in the said user unit'"'"'s memory means, that corresponds to the particular message, wherein each user unit further includes an input device by means of which a user can give input data and selection in reply to a message presented on the user unit'"'"'s display means, and wherein the interface part is intended to transmit the input data and the selections given by the user to the dialogue part of the central computer unit, characterised in that a plurality of presentation objects corresponding to a plurality of messages are stored in a picture dictionary in each user unit'"'"'s memory means;

and in that the respective interface part further includes a respective picture interpreter which coacts with the picture dictionary and which presents the presentation object pointed-out by the dialogue part on the display means and which interprets those operations carried out by the user for retransmission to the dialogue part of the input and selections given by the user.

10. An arrangement according to claim 9, characterised in that a plurality of picture directories are stored in each user unit memory means, these picture directories each including a presentation object which has the same messages but is in different mother languages;

and that the picture directory required can be selected from the user unit.

11. An arrangement according to claim 9, characterised in that a said message can be presented on a said user unit in accordance with the properties possessed by the said user unit with regard to processing capacity, graphics and sound;

and in that a specific message corresponds to a single presentation object at each individual user unit.
