  3. Functions of Visualizations • Answer a question • “One image = One diagnosis” • Make decisions • Support analysis and reasoning • To explore and discover; encourage creativity • Look at things in a new way • “The purpose of computing is insight, • not numbers” [R. Hamming] • Communicate information to others • Make a point • Tell a story • Inspire Information Visualization

  4. Functions of Visualizations • 1. Recording information • e.g. table of logarithms, blueprints and • telescope images • 2. Understanding information • Computer -> Display -> Person • w/ feedback and interaction • 3. Presenting information • Display -> People • Share, collaborate, revise, … Information Visualization

  9. Amplifies Cognition/Perception • Expand working memory • Reduce search time • Pattern detection and recognition • Perceptual inference • Perceptual monitoring and controlling attention • Interaction is important for cognition • Card, Mackinlay, Shneiderman • Readings in Information Visualization Information Visualization

  10. Route Maps Overlaid Route Sketched Route • Find cognitive and perceptual principles • Optimize the visualization according to these principles Agrawala and Stolte, Rendering Effective Route Maps, SIGGRAPH 2001 Information Visualization

  11. 5. Interaction Gibson’s Experiment Goal: Match 2 shapes Active touch: 96% Passive (rotation) 72% Passive (imprint) 49% From J. J. Gibson (1966) The Senses Considered as a Perceptual System, p. 124 Thanks to David Kirsh for this example. Information Visualization
