<p>A method is disclosed for specifying and executing independent, multi-media tasks along a synchronizing time-line, preferably in the form of a spreadsheet matrix with the event elements making up the rows and the time periods the columns. The media include various pieces of hardware such as touch screens, voice synthesizers, video disk players, and the like. In designing a presentation, the author types into the matrix indications of which piece of hardware will be operating and for what specified period of time during the presentation. This information is also accessible to all other events in the presentation thereby allowing complex multi-media presentations to be designed by a user who is relatively unsophisticated in using computers.</p> |
