Abstract

A system for synchronizing application programs which together provide a multi-modal user interface, which comprises multiple application programs which provide the various interface of the multi-modal interface and which are in communication with a synchronization manager. Means are provided to detect status changes in the application programs and to communicate such status changes, in the form of data updates to the synchronization manager. The synchronization manager is operative to communicate such a data update to the application program in which the data update did not originate so that the application programs are synchronized.

Claims

1. A system for the provision of a multi-modal user interface which has a first user interface part and a second user interface part, at least the first user interface part operating according to stored dialogues;

and

control means arranged to control the operation of the multi-modal interface and operatively connected to the first and second parts;

wherein the first part has, for at least some of the possible dialogues which it supports, multiple alternative versions of the dialogues, the system being configured to switch between dialogues and between the alternative versions of the dialogues in dependence upon conditions in the multi-modal user interface.

2. A system as claimed in claim 1, wherein the second user interface part operates according to stored dialogues;

wherein the second user interface part has, for at least some of the possible dialogues which it supports, multiple alternative versions of the dialogues, the system being configured to switch between dialogues and between the alternative versions of the dialogues in dependence upon conditions in the multi-modal user interface.

5. A system as claimed in claim 1, wherein the first user interface part provides a visual user interface and wherein the second user interface part is an audio interface.

6. A system as claimed in claim 1, wherein the conditions in the multi-modal user interface to which can cause switching between dialogues and/or tracks in a dialogue include:

user input;

user preferences;

the presence or absence of additional modes of the multi-modal user interface; and

system state.

3. A system for the provision of a multi-modal user interface which has a first user interface part and a second user interface part, at least the first user interface part including first means to provide cues to a user of the system according to stored dialogues and second means to receive input from the user;

and

control means arranged to control the operation of the multi-modal interface and operatively connected to the first and second means;

wherein the first means has, for at least some of the possible dialogues which it supports, multiple alternative versions of the dialogues, the system being configured to switch between dialogues and between the alternative versions of the dialogues in dependence upon conditions in the multi-modal user interface.

4. A system as claimed in claim 3, wherein the second user interface part includes third means to provide prompts to a user of the system according to stored dialogues and fourth means to receive input from the user;

wherein the third means has, for at least some of the possible dialogues which it supports, multiple alternative versions of the dialogues, the system being configured to switch between dialogues and between the alternative versions of the dialogues in dependence upon conditions in the multi-modal user interface.
