    • Abstract: Data visualizations are graphical representations of data designed to help us extract meaning. This talk will begin with an overview of visual thinking considered as an active process involving visualizations as well as the more usual cognitive constructs such as visual working memory. An important part of thinking with visualizations is our brain executing a continuous stream of visual queries on the display by means of eye movements and pattern extraction processes. I will give two examples of the application of this elementary theory. The first example will address the question of when extra windows are needed in a data visualization interface. The second example will be based on the interactive graphical tools we have developed to analyze data obtained from tagged humpback whales. I will make the case, based on simple active vision-based arguments, that turning time varying data into spatial patterns is almost always the right thing to do. My broader goal will be to argue that a basic knowledge of how visual thinking works should be considered as essential knowledge for the designer of interactive systems.
