Structured interactive animation for multimedia documents

We propose a model for interactive animation (IAN) of structured objects in multimedia documents. The model naturally integrates usual multimedia elements (text, image, video, sound) with motion and graphical changes of geometric objects, but also with user and inter-object interaction. Animation is defined in a declarative and highly structured manner: a set of objects with their composition relations and a scenario composed of event-condition-action rules. Our purpose is to enable both easy authoring and database management of animations.
