Welcome to the CSU Witt Perception Lab

The lab focuses on two research areas: Information Visualization and Action-specific Perception.

Research on information visualization leverages knowledge about the visual system for constructing visualizations (graphs, pictographs, charts) to enhance understanding of simple and complex information. The specific focuses of the research are on basic graph design and understanding uncertainty. The work on uncertainty is currently being applied to medical decisions and health disparties, as well as climate and weather predictions.

Research on action-specific perception focuses on how visual perception of spatial properties such as size, distance, and speed is influenced by the perceiver’s ability to act on the target.  For example, softball players who are hitting better than others see the ball as bigger.  As another example, targets appear to be moving slower when they are easier to catch.  This research demonstrates that perception is action-specific, meaning that what is seen is specific to the observer’s ability to perform the intended action.
