Multimodal Presentation of Dynamic Object Scenarios on the Web

We describe a Web based presentation system for dynamic object scenarios. The system produces multimodal presentations based on 3D interactive animations, coordinated with adaptive spoken comments. User profiling and comments production are performed through the interaction with a human-like agent. The system has been developed as part of a research project on support tools for learning about sail racing rules and strategies. The presentation system works in conjunction with an expert authoring system for sail racing scenarios. The software architecture is modular and flexible, explicitly targeted to the Web environment. Moreover it is general enough to be easily reused in other domains and applications involving dynamic object scenarios.
