The overall goal of the Computer Graphics Research Laboratory at the University of Pennsylvania is the modeling and animation of human movement. That central topic drives a number of related research interests covering a broad scope from image synthesis to natural language interfaces. Jack (TM) is an animation system developed at this Laboratory. In this system animation follows from model-based simulation. Jack provides biomechanically reasonable and anthropometrically-scaled human models and a growing repertoire of behaviors such as walking, stepping, looking, reaching, turning, grasping, strength-based lifting, and collision-avoidance posture planning. Trying to make a human figure move in ways that people expect a human to move in carrying out a task is a formidable problem: human models in Jack are highly articulated, with over 100 degrees of freedom.
