An ICON Programming Technique for Multimedia Presentation Designs

摘要

Relations among temporal intervals can be used to asist the automatic generation of multimedia presentations. In this paper, we analyze the domains of interval temporal relatins. A set of algorithms is proposed to derive reasonable relations betwene intervals. Possible conflicts in the user specification are firstly detected and eliminated. Our mechanism then constructs partial order relations among temporal intervals before the presentaiton time chart is built. The algorithm is extended for objects in an arbitrary n-dimensional space. Thus, presentation layouts in 2-D space, or Virtual Reality object representations in 3-D space can be constructed. We use our algorithms to design a reasoning system that generates the schedule and layout of multimedia presentations.
