DescriptionThree dimensional visualizations are used in numerous fields to help people gain a better understanding of the subject. Because these visualizations are growing both in prevalence and in complexity, it is becoming increasingly important that people understand them. Prior studies demonstrate that this is not the case with a significant portion of the population. This suggests that we either make the visualizations easier or provide adequate training through our education venues to help people understand 3D visualizations. Unfortunately, making visualizations easier is not always an option because the visualization is necessarily hard because of the problem being tackled, e.g., viewing an MRI scan of a human being. Currently, little is done in our education systems for improving 3D visualization comprehension. This may be because we are not really sure how to teach such skills. To be able to train people in comprehending 3D visualizations, we need to understand how people comprehend and process these visualizations which is a non-trivial task. Overall, the goal of this thesis is to determine what properties of 3D visualizations make their comprehension difficult. In order to do so, a visualization test was designed to assess the ability of subjects to understand the internal structure of 3D block diagrams. This test was administered to subjects who were videotaped solving the visualization problems. An analysis of the verbal protocols of these subjects identified strategies that subjects used to process the 3D visualizations and problem areas where they provided inaccurate solutions. The analysis uncovered those visualization properties that created difficulties for subjects and also suggested training methods for presenting these properties in a way that would help improve the ability of individuals to comprehend visualizations.
