Jeffrey Heer- Voyagers and Voyeurs: Supporting Asynchronous Collaborative Information Visualization

In this talk, I will describe our work recasting interactive information visualizations as not just analytic tools, but social spaces supporting collective data analysis. I'll discuss the design and implementation of sense.us, a web site supporting asynchronous collaboration across a variety of visualization types. The site supports view sharing, discussion, graphical annotation, and social navigation and includes novel interaction elements. I will also report the results of user studies of the system, observing emergent patterns of social data analysis, cycles of observation and hypothesis, and the complementary roles of social navigation and data-driven exploration.
