Abstract

The results presented in this paper illustrate how a specific map visualization technique is sensitive to setting: a comparative evaluation of the technique gives conflicting results depending on where it takes place. While prior research has explored the impact of factors other than basic visual perception on visualization techniques, relatively little attention has been directed toward the physical setting in which the technique is used. We present results from a study involving 120 participants, comparing the effectiveness of two different geovisualization techniques in promoting recall of map layout. Recall was shown to be sensitive to setting, such that one technique in particular was more effective in a noisy public space than in a controlled, 'white-room' environment. The results have implications for the validation and measurement of information visualization techniques as a whole, and in particular for those employing motion as a communicative attribute.
