Abstract

In this paper, we discuss the use of visual representations to assist people in understanding complex information about sea level rise and climate change. We report on the results of a 2011 study in which we conducted plus-minus document usability evaluations of documents describing the mechanisms and consequences of sea-level rise in coastal areas. The protocol included 40 participant interviews and post interview quizzes. We tested with three documents, one that presented information for the U.S. southeastern coastal region and two that presented information "localized" for the two areas in which we conducted the research. Findings indicate that participants had difficulty with information presented in graphs and maps and that, while they indicated preferences for localized information, localized images did not improve understanding of complex information.
