Visualizations for Broad Audiences ‐ Lessons Learned Interaction constrained by Hardware/software Hardware design with a few available knobs Minimize interaction to pre ‐ sets Few view positions Few lighting stages Heterogeneous audience Doctors do diagnosis Grandparents enjoy images [6] [7] Aesthetics important, more than realism Eduard Gröller 19

Visualizations for Broad Audiences ‐ Lessons Learned System must be Interactive Robust (graceful degradation) No [costly] pre ‐ processing possible Engineering effort Just good enough solution [6] [7] Not 100% realistic, not 100% correct Glanceable visualization, graspable interaction, small learning effort Adhere to established preconceptions Users got accustomed to a fast, heuristic model Acceptance of more elaborate model difficult Eduard Gröller 20

Abstract Adjust, Just Adjust Developing visualizations for broad audiences requires glanceable graphics and graspable interactions. This talk will concentrate on interaction facilitation through automatic adjustments. The first example illustrates an automatic color scale adjustment in a bio ‐ molecular setting to accommodate contradicting and overlapping color schemes across scales. The second example discusses output ‐ sensitive interaction to make changes in the input proportional to changes in the output, or to visually indicate the sensitivity of input changes with respect to output changes. The third example deals with visualization of 4D ultrasound data, which is targeted to a broad audience in prenatal imaging and diagnosis. Lessons learned during this project are presented. The talk makes a case for automatically reducing interaction complexity in visualizations for broad audiences. Eduard Gröller 26
