Abstract

A method of synchronising the delivery to a user of first information which is to be presented to the user via a visual display of a multi-modal interface and of second information which is to be presented to the user over a visual or an audio interface of the multi-modal interface, in which the multi-modal interface process estimates the total time needed to deliver the first information to the visual display or to a store local to the visual display, estimates the total time needed to deliver the second information to the visual or audio interface or to a store local to the visual or audio interface; and then uses the estimates to determine whether the presentation to the user of the first or second information to the user needs to be delayed to achieve a desired synchronism of presentation; and then applies any delay determined to be necessary to achieve the desired synchronism of presentation.
