Do it yourself? Interactive visualizations as cognitive tools Stephan Schwan Universität Tübingen
Overview • Cognitive difference between unmediated observation and watching a media-based depiction • Cognitive difference between a noninteractive vs. an interactive depiction S. Schwan – Interactive visualizations as cognitive tools
Cognitive benefits of media-based visualizations • Information storage and transmission • Depiction of hypothetical scenarios • „Cognitive customization“ • Choosing viewpoints and distances • Replaying important event parts • Skipping unimportant event parts • Highlighting event boundaries • Changing the presentation speed (e. g. slow motion) S. Schwan – Interactive visualizations as cognitive tools
Working division between author and user shaping Author processing Medium User S. Schwan – Interactive visualizations as cognitive tools
Characteristics of interactive media processing shaping modifying Author Medium Internal vs. external User Author vs. User S. Schwan – Interactive visualizations as cognitive tools
Empirical questions 2. Do the users possess appropriate interaction strategies? 3. Does an interactive information presentation lead to more effective and / or efficient learning? Author vs. User Internal vs. external 1. Do the interactivity-related decisions of the authors match the respective expectations of the users? Whole System S. Schwan – Interactive visualizations as cognitive tools

Summary • Media allow for experiential customization in general • Interactive media allow for individualized customization • Necessary conditions - Match between author and user - Complementarity of external actions and internal processes - Epistemic actions outweigh cognitive overhead S.
