The PerForM (Perception For Movement) Lab is a part of the Multidisciplinary Vision Research Laboratory, and is dedicated to bettering our understanding of the mechanisms that allow humans to perform everyday visually guided actions, like catching a ball, driving a car, or walking over uneven terrain. Although these are natural actions, the natural environment does not afford the experimental control required for the rigorous testing of hypotheses about how vision is used to guide action. In contrast, traditional laboratory-based study has a tendency to validate hypothesis that are unique to the laboratory environment, and unrepresentative of real-world behavior. To resolve this conflict, the PerForM Lab leverages advances in virtual reality and motion capture technologies that afford both freedom of movement, and a naturalistic visual experience. Using these tools, we are able to conduct controlled, naturalistic studies of the human visual and motor systems.
