A Z-SPECIFICATION APPROACH TO MULTIMEDIA MODELING

An interactive multimedia presentation system is introduced. We first define a model for interactive presentations in the Z notation. The mo del looks at tile presentation from two views: the navigation view and the representation view. The presentation navigation is based on mess age passing among presentation frames of a presentation, while common information is inherited and shared by frames. The system allows a pre senter to plan the audience's reaction in advance. When the audience i s watching a presentation, the underlying inference system is learning from his/her responses. This mechanism makes a presentation to be pro ceeded again act according to the audience's background and knowledge. Thus, the resulting presentation is more diversified. We also propose a multimedia resource database and a number of important resource att ributes that we used in the classification of resources. A resource br owser is implemented to allow users to preview resources and maintain tile database. The prototype system is implemented under MS Windows. T his system can be used for general purpose presentations or demonstrat ions in different fields such as education, training, product demonstr ation. and others.
