Exploratory visualization research at the University of Massachusetts at Lowell

Abstract This paper describes research activities in the University of Massachusetts—Lowell's ongoing Exvis project, a perception-driven approach to the visualization and exploration of data. We discuss the evolution of the Exvis exploratory visualization systems and provide a variety of examples of multidimensional data representations based on visual perception of line texture and color, and on auditory perception of aggregations of complex time-varying sounds. We also discuss future activities.
