<p>A system provides dynamic control of a visual and/or audio presentation. The system comprises a storage such as DASD for data defining "stories" i.e. a multiplicity of still images or video segments and/or respective audio clips. A program file defines a list of the stories for the presentation, a sequence for presenting the stories in the list, and a time interval for presenting each story or between successive stories in the sequence. A control program directs display of the stories in the list in the sequence according to the time interval. The time interval can be dynamically changed during the presentation by a user via a system console. Pursuant to such a change, the subsequent stories are presented according to the changed time interval. This permits the user to tailor the speed of the presentation to the audience. One or more of the stories is divided into elements providing different levels of information, and the control program directs display of most or all of the elements if the interval is relatively long and directs display of fewer elements or a single element if the interval is relatively short. <IMAGE></p> |
