Application synchronisation

摘要

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.
