Extracting Explicit and Implict Information from Complex Visualizations
Abstract
How do experienced users extract information from a complex visualization? The authors examine this question by performing an experiment. They presented experienced weather forecasters with visualizations that did not show the needed information explicitly and examined their eye movements. They replicated Carpenter and Shah (1998) when the information was explicitly available on the visualization. However, when the information was not explicitly available, they found that forecasters used spatial reasoning in the form of spatial transformations to extract the needed information. They also found a strong image component for constructing meteorological information.
