Perceptual Affordances of Wall-Sized Displays for Visualization Applications: Color

Wall-sized displays offer the opportunity to display very large information spaces. Most data representations can be scaled to wall size but display walls are not simply big desktop monitors. We do not yet know how the perceptual affordances of a wall, such as the wide viewing angles they cover, affect how data is perceived and comprehended. In this paper we call for more studies on the perception of data on wall-sized displays and discuss-with the example of color-several aspects of wall setups that we hypothesize will most affect the perception of this visual variable.
