Visualizing modeling heuristics: an exploratory study

Rapidly advancing modeling technologies, such as data mining algorithms and new modeling languages, are making modeling accessible to an ever-broadening cross-section of knowledge workers. Advances in computer display technologies are also being incorporated into modeling software. Both research and anecdotal evidence suggest that visuals are important in the process of modeling. However, in order for potential modelers to make the most efficient and effective use of these new technologies, the software must incorporate visualization in such a way as to facilitate the process of modeling. In order to accomplish this, software designers and developers, who have tended to focus more on perceptual than cognitive issues, need to better understand the cognitive role of visualization in modeling. The goals of this research include 1) exploring the cognitive role of visualization in modeling, 2) gaining a better understanding of the process of modeling and moving it toward being a science, and 3) providing a more theoretical basis for the use of visualization in modeling tools. This paper will cover background on the process of modeling and visualization, mental models theory, our visualization-incorporating extension of mental models theory, the design of a Modeler’s Assistant tool, and an experiment in modeling and visualization using the Modeler’s Assistant.
