i-Mu.S.E.-Interactive Multimedia Scenario Editor

Presents a rich model for interactive multimedia presentations and an implemented authoring system based on the model. The model covers the issues of interaction in terms of external and internal events and also the spatiotemporal composition of media objects in the context of the presentation. The authoring is carried out in three consecutive phases related to: (i) selection and transformations of the media objects that are to participate, (ii) definitions of the events (atomic and complex) that the presentations are to consume, and (iii) specification of the scenario of the presentation in terms of scenario tuples. Furthermore, in order for the presentation specifications to be rendered, appropriate algorithms have to be developed. We present the transformation of the declarative specifications into procedures. The authoring system was fully implemented using the authoring tool Asymetrix/Toolbook 4.0 under Windows 95.
