Interactive Visualizations Enhancing Cognitive Processing: A Comprehensive Overview

This overview explores the cognitive benefits of interactive visualizations as cognitive tools, highlighting the differences between unmediated observation and media-based depictions. It delves into the impact of interactivity on user processing and the interplay between authors and users in shaping cognitive processes. Key aspects such as information storage, viewpoint selection, and customization are discussed, along with empirical questions on the effectiveness of interactive information presentation. The importance of experiential customization and individualized interactions is emphasized for optimal learning outcomes.

Presentation Transcript

  1. Do it yourself? Interactive visualizations as cognitive tools Stephan Schwan Universität Tübingen

  2. Overview • Cognitive difference between unmediated observation and watching a media-based depiction • Cognitive difference between a non-interactive vs. an interactive depiction S. Schwan – Interactive visualizations as cognitive tools

  3. 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

  4. Working division between author and user shaping processing User Author Medium S. Schwan – Interactive visualizations as cognitive tools

  5. Characteristics of interactive media User processing shaping Internal vs. external modifying Author Medium Author vs. User S. Schwan – Interactive visualizations as cognitive tools

  6. Empirical questions • Do the interactivity-related decisions of the authors match the respective expectations of the users? • Do the users possess appropriate interaction strategies? • Does an interactive information presentation lead to more effective and / or efficient learning? Author vs. User Internal vs. external Whole System S. Schwan – Interactive visualizations as cognitive tools

  7. Example video S. Schwan – Interactive visualizations as cognitive tools

  8. Interactive behaviour Stops Slow motion Fast motion Changes in playing direction S. Schwan – Interactive visualizations as cognitive tools

  9. Variability of viewing time Standard deviation (sec) S. Schwan – Interactive visualizations as cognitive tools

  10. Viewing time Sec S. Schwan – Interactive visualizations as cognitive tools

  11. Practicing time Sec S. Schwan – Interactive visualizations as cognitive tools

  12. Overall learning time Sec S. Schwan – Interactive visualizations as cognitive tools

  13. 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. Schwan – Interactive visualizations as cognitive tools
