Using a New Information System for Analysis of the Relation between Presentation Skills and Understandability
Abstract: What kinds of presentation skills make one’s presentation understandable for audience? In this paper, we developed an information system and conduct experiments by using it to answer the above question. The authors investigated about eighteen factors. As a result, the factors of presentation understandability are Contents factor and Visual factor. Especially, Contents factor is relative to the story consistency, and Visual factor is relative a using visual effect (picture/photography/table/graph/animation). In addition, the authors compared these results with a factor analysis of the questionnaire about presentation skills and understandability in order to confirm these results are correct. On the other hand, our result shows that insufficient explanation makes presentation cramped.
