S. Schwan – Interactive visualizations as cognitive tools
• Cognitive difference between unmediated observation and watching a media-based depiction
• Cognitive difference between a non-interactive vs. an interactive depiction
Overview
• Information storage and transmission
• Depiction of hypothetical scenarios
• „Cognitive customization“
