Developing Presentation Based on Diagrammatic Information Structure by a Virtual Human Agent

本研究课题的目的是设计开发一个系统，用户可以指定或自动提取特定数据或信息的本质、结构和重要或显著点，然后制作角色动画来解释它们。2005年，我们开发了一个系统，用户可以指定表中元素之间的关系，然后制作动画。这些关系以树结构表示。为了产生动画，遍历树，并且将所访问的元素和关系解释为包括语音文本和演示者的手势的演示场景。在2006年，我们首次将该系统扩展为一个可以生成图形和表格演示动画的系统。在图形表示中，智能体可以解释值序列的趋势（例如，增加或减少）以及显著点（例如，最大值或最小值）。其次，我们研究了机制，自动选择候选人的显着点与他们的功能。它使用户能够选择一些候选人，然后演示动画解释所选择的显着points.The上述工作是在第五届IASTED国际会议上提出的可视化，成像（VIIP 2005），图像处理和SIGGRAPH 2006研究海报。

The purpose of this research project is to design and develop a system where the essence, structure, and important or remarkable points of particular data or information are specified by a user and/or extracted automatically, and then a character animation is produced to explain them.In 2005, we developed a system where a user specifies relationships among elements in tables, and then produce an animation. The relationships are represented in a tree structure. To produce an animation, the tree is traversed and the visited elements and relations are interpreted into presentation scenarios including speech texts and presenter's gestures. The interpretation rules are represented by templates.In 2006, we first extended the system into one that can generate presentation animation for graphs as well as tables. In graphical presentations, the agent can explain the tendencies of sequences of values (for example, increasing or decreasing) as well as the remarkable points (for example, maximum or minimum). Next we studied the mechanism which automatically selects candidates of remarkable points with their features. It enables users to choose some of the candidates, and then the presentation animation explaining the chosen remarkable points is produced automatically.The above work is presented in 5th IASTED International Conference on Visualization, Imaging (VIIP2005), and Image Processing and SIGGRAPH 2006 Research Posters.
