Abstract

The invention relates to multi-modal computer interfaces and the synchronisation of two or more application programs which have user interfaces which make up the multi-modal interface. The invention employs a synchronisation server process with blackboard style data store for posting the changes made to any one particular application program to the other application programs. Data updates pass via the synchronisation server. A map file is provided for translating data provided by one application program into the formats suited to other application programs, and vice versa. In this way, application programs are not limited by a common dialogue but are autonomous, thus providing a cohesive and highly flexible user interface.

Claims

1. A system of apparatus for synchronising a group of application programs which together provide a multi-modal user interface, the system including;

processing means in communication with, via one or more communication links, the group of program applications, wherein each of the program applications is capable of communicating data with the processing means, wherein changes in the status and data content of the application programs are communicated to the processing means as data updates, the processing means having means to translate the received data updates into the format or formats suitable for other application programs of the group, and the processing means being configured to communicate the original or translated data updates as appropriate to the other application programs of the group so as to synchronise them.

2. A system as claimed in claim 1, wherein at least one of the application programs of the group provides a visual interface and at least one of the application programs provides a speech interface.

3. A system as claimed in claim 1 or claim 2, wherein memory means are provided to store received data updates for the processing means, further memory means being provided to hold rules for the translations to be performed.

4. A system for synchronising application programs according to any one of the preceding claims, wherein the system is configured to allow a further application program to join the group of application programs upon receipt by the processing means of a request to do so.

5. A system for synchronising application programs according to any one of the preceding claims wherein at least one of the application programs is a web browser.

6. A system for synchronising application programs according to any of the preceding claims wherein mapping means are provided for mapping said data received from one application program into a form suitable for use by the other application programs of the group.

7. A system for synchronising application programs according to claim 6 wherein the mapping means uses a synchronisation mark-up language.

8. A system for synchronising application programs according to claim 7 wherein the synchronisation mark-up language uses extensible mark-up language.

9. A system for synchronising application programs as claimed in any one of the preceding claims, wherein the processing means is in communication with means suitable for retrieving web pages.

10. A method of synchronising a group of application programs which together provide a multi-modal user interface, the method including the steps of:

(i) monitoring an application program for application program data values, said application program forming part of the group of application programs; and

(ii) upon detecting an application program data value, transmitting said application program data value to a synchronisation manager;

(iii) translating said application program data value into one or more formats suitable for use by the other application programs of the group; and

(iv) transmitting the application program data value in original or translated form to other of the application programs of the group.

11. A method as claimed in claim 10, wherein the synchronisation manager carries out a process between steps (ii) and (iv) to decide to which of the application programs application program data should be transmitted in step (iv).

12. A method as claimed in claim 10, further including the steps of:

(v) the synchronisation manager notifying the other application programs in the group that an application program data value data has been received in step (ii),

(vi) in response to the notification of step (v) receiving a request from any or all of the other application programs in the group for a copy of the application program data value;

(vii) in response to a request received in step (vi) carrying out step (iv) in respect of the or each requesting application program(s).

13. A method as claimed in any one of claims 10 to 12, wherein the synchronisation manager maintains a store of the application program data values received in step (ii)

14. A method of synchronising a group of application programs according to any one of claims 10 to 13, comprising the step of introducing a further application program to the group of application programs.

15. A method of synchronising a group of application programs according to claim 14, wherein a request is made to the synchronisation manager for a further application program to join the group by the further application program.

16. A method of synchronising a group of application programs according to claim 14, wherein a request is made for a further application program to join the group by one of the group of application programs.

17. A method of synchronising a group of application programs according to claim 14, wherein the request is made for a further application program to join the group by the server itself in response to the detection of a change in status of an application program.

18. A method of synchronising a group of application programs according to claim 17, wherein the change in status is a fluctuation in the capacity of the communication link between one or all of the application programs in the group.

19. A method of synchronising a group of application programs according to any one of claim 10 to 18, including the step of referring to a synchronisation table in order to convert the user input data received from the user interface of one application program into data suitable for use in any one of the other application programs in the group.

20. A method of synchronising a group of application programs according to any of claims 10 to 19, further including the step of obtaining data from the internet upon request from any one of the application programs and transmitting this data to the application program which made the request.

21. A method of synchronising a group of application programs according to claim 20, including notifying the other application programs in the group that a request for data from the internet has been made, and

submitting a request from any or all of the other application programs in the group for a copy of the data, and

transmitting the requested data to each of the application programs that submitted a request.

22. A method of synchronising a group of application programs according to claim 20, including notifying the other application programs in the group that a request for data from the internet has been made, and

submitting a request from any or all of the other application programs in the group for a copy of the data, and

determining the suitability of the data from the internet for each of the application programs that made the request, such that

if the data is determined as not suitable for use by an application program then referring to the synchronisation table in order to determine the location of equivalent data on the internet which would be suitable for use by the application program, and;

retrieving the equivalent data from the internet and transmitting this data to the application program.
