a user study of a new website (sense.us) that supports asynchronous collaboration across a variety of visualization types. its collaborative features includes view sharing, discussion, graphical annotation & social navigation. results of the study show emergent patterns of social data analysis, including cycles of observation & hypothesis, & the complementary roles of social navigation & data-driven exploration. the study ran in 2 different parts: a pair of controlled lab studies & a 3-week live deployment on the IBM corporate intranet.
"we believe these results show the value of focusing on the social aspects of visual analysis. our user studies indicate that combining conversation & visual data analysis can help people explore a data set both broadly and deeply. from a design perspective, there seems to be a promising opportunity for exploring new widgets & modes of interaction aimed at enhancing collaboration."
