Multimedia presentation design using data flow diagrams

Structured analysis/design methodology has been used in software development for many years. We propose a revised data flow diagram technique and system based on the structured analysis methodology. The system allows a multimedia presentation designer to stepwise refine his/her presentation toward an interactive Petri net, which defines the temporal behaviour of the presentation. The generated presentation can mutate itself at runtime. Therefore, the presentation can act according to the audience´s responses. The system is implemented in Visual C++ and Visual Basic running under Windows 95/NT
