Task dependence, veridicality, and pre-attentive vision: Taking advantage of perceptually-rich computer environments

Abstract

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 taskdependency 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.
