Task dependence, veridicality, and preattentive vision: taking advantage of perceptually rich computer environments

This paper examines the mapping of data onto perceptual dimensions to create a visualization. The choice of perceptual variables depends critically on the goals of the visualization, and this task-dependency has implications for (1) the veridicality of the representation, (2) the mapping of data onto 'preattentive' features, and (3) the use of multiple senses to represent the data.
