Modeling, Display, and Understanding Uncertainty

Fluid Eddy Visualization

The Spatial Thinking Lab is collaborating with researchers at the University of Utah, Clemsen University, and Texas A&M University to establish the foundations for capturing the uncertainty associated with predictive simulations for policy decision making. Aspects of the project include Simulation and uncertainty quantification, developing methods of visualizing uncertainty and evaluating these visualizations by examining perception, cognition, and decision making in the presence of visualizations of uncertainty. This project is supported by the National Science Foundation.

Mary Hegarty’s research is on spatial thinking in complex activities such as comprehension, reasoning, and problem solving. In research on mechanical reasoning and interpretation of graphics, she uses eye-fixation data to trace the processes involved in understanding visual-spatial displays (diagrams, graphs and maps), and making inferences from these displays. A unique characteristic of her research is that she studies spatial thinking from the perspective of individual differences as well as employing more commonly used experimental methods.
