Conference on Vision for Reach and Grasp

University of Minnesota 2-4 October 1997

Holiday Inn Metrodome Minneapolis Minnesota USA

Humans and other primates have the remarkable ability to use vision to plan and control skilled movements directed at objects in their environment. Understanding this ability is a central problem in neuroscience and cognitive science. Over the past two decades, we have seen major progress in our understanding of the input side of the problem: computational theory has defined the visual problems to be solved; behavioral experiments have discovered mechanisms and constraints used in human vision; anatomy and physiology have advanced our knowledge of the visual architecture of the primate brain. At the same time, we have also seen great growth in our knowledge of the properties and mechanisms of the motor outputs, involving eye, hand and body movements. Despite the interdisciplinary progress on the extreme ends of the problem --we know relatively little of how the visual input is transformed into motor action. This conference will draw together scientists in vision and motor control across behavioral, computational and physiological domains. We will address questions at the interface between vision and action, with a focus on vision for reach and grasp movements. The Minnesota Conference on Vision for Reach and Grasp is Sponsored by: the National Science Foundation, the McKnight Foundation the Human Frontiers Science Program, the University of Minnesota's Medical School, College of Liberal Arts, Neuroscience Program, Psychology Department and Cognitive Sciences Center
