Abstract

Our goal is an interface that allows novice users to browse and enjoy Web contents as easily as they can watch TV. Given this goal, Web page contents should be converted into fully-animated TV-like audio/visual contents, taking users' mental situation into consideration. Moreover, this paper focuses on generating adaptive Web page presentation according to the emotional parameters. To get the user's interest and attention, we utilize two robots which can speak. In order to develop conversions that take account of the user's mental situation, we performed two step surveys. First, the emotional impressions of primitive audio/visual effects were investigated. Second, the effect of the combinations of robot and primitive effects was investigated. The first experiment yielded a 'situation composition grammar;' given an emotional situation, the appropriate audio/visual effects can be selected. The second experiment suggested that presentation media components exhibit mutual interaction. We implemented a prototype and subjectively evaluated it. The results confirm the effectiveness and validity of our proposal.
