  1. Visualization Leslie Wu Loren Yu

  2. Is this a good visualization? http://tinyurl.com/6rr22g

  3. What is visualization? Definition: The use of computer-supported, interactive, visual representations of data to amplify cognition • Situations / Tasks / Users (STUs)

  4. Creating good visualizations “I wonder if people [build upwards from ‘building blocks’] to create the next best visualization, [or if theory comes after the visualization] to justify why the visualization is a good one?” - Marcia Lee

  5. What tasks do visualizations support?

  6. Visualization Tasks

  7. Cost Structure • Different visual representations have different cost structures. • Some visual characteristics are “automatically” recognized, while others require conscious effort to interpret

  8. Cost Structure?

  9. How does visualization amplify cognition? • Increasing available memory and processing resources • Reducing search costs • Visual detection of patterns • Perceptual inference operations • Perceptual attention for monitoring • Encoding information

  10. Consequences of Visualization “[W]hen do you use visuals and when do you just show a table?" - Neil Patel Easier is not necessarily better “[R]etention occurs alongside some amount of expended effort… [I]f I have to spend less effort thinking about something, I'm less likely to remember it” - Neema Moraveji“I wonder if the ease of representing information in a particular form colors how we approach it… If we continually see tables used to organize information, do we become less receptive to the data it models?" - Amal Aziz

  11. Visualizations for whom? A. In which domains would visualization be most useful? • "I would also be interested to read some discussion of professions or domains that could really benefit from increased work in the area of information visualization.  Who uses a vast amount of complex data that presents a visualization challenge?" - Sara Mitchell B. How does visualization fit into societal organizations? • "Where does visualization fit into to large systems of human minds working together?" - Nick Wolfe

  12. Visualization in the Future • Different Domains: Scientific Visualization vs. Information Visualization • Visualization for the Masses • Mobilization/Miniaturization of visualization“[I]t would be nice to explore the different possibilities of [mobile] devices. How much context can be used…? - Nick Briggs • Automatically generating visualizations based on user models"it would be neat to see a system that models user behavior… [to generate visualizations] that would respond well to human senses and perception..." – Michael Smith

  13. Collaborative InfoViz and Social Cognition • Many Eyes comments: http://services.alphaworks.ibm.com/manyeyes/browse/comments • Hans Rosling: http://www.ted.com/index.php/talks/view/id/92
