The ExVis System was developed at the Institute for Visualization and Perception Research at the University of Massachusetts Lowell's Computer Science Department. ExVis constructs iconographic data visualizations from multidimensional datasets, and offers a highly interactive user interface to permit the rapid selection of data attributes and data mappings for display. ExVis is able to display up to 15 distinct attributes simultaneously, using line-oriented, color-field and sonic "icons". The visual icons are displayed en masse - to create a visual texture that would conceivably exploit the human visual systems' preattentive processes, such that trends and patterns are readily distinuguished. Sound is also used as a reinforcement, or as a channel for additional data parameters. This is a much different approach than automated data mining, where algorithms determine relationships and structure in data. ExVis is meant to be used in an exploratory data analysis mode, where data can be rapidly and easily manipulated, organized into perceptually compelling displays, with flexibility for changing viewing parameters.
