For those of you in or around Münster in Germany: We will have a special guest at our GI Forum talk series tomorrow, Sara Fabrikant from the University of Zürich. Her talk is entitled Looking through static and dynamic geovisualization displays and will be held at the Institute for Geoinformatics, Robert-Koch-Str. 26-28, 48149 Münster in room 72 and start at 4:15pm (tuesday, december 5).

Abstract:

In this lecture I present an empirical evaluation framework based on the eye movement data collection method to investigate the relationship of thematic relevance and perceptual salience in static e.g., visual variables: color hue, color value and orientation) and animated (e.g., dynamic variables including transitions) map displays. In controlled experiments we currently investigate how novices’ viewing patterns are modified when thematically relevant items are made perceptually more salient through design. In essence, we are asking if perceptually salient elements draw novice viewers’ attention to thematically relevant information, whether or not users have domain knowledge.

Results collected thus far suggest that display design (i.e., saliency) does influence viewing behavior and inference making, whether participants have prior knowledge or not (i.e., training). With the collected empirical evidence we hope to provide better understanding of how people extract relevant information from static and dynamic maps, and how people make inferences from these map displays for knowledge
construction of dynamic geographic processes.
