Colloquium Speaker: James Hahn


Professor James Hahn received his Ph.D. from the Ohio State University in 1989 and has since been on the faculty in the Department of Computer Science at the George Washington University. He is the founding director of the Institute for Computer Graphics and the founding co-director for the Laboratory for Advanced Computer Applications in Medicine. His areas of interests are computer animation, virtual reality, and computer graphics. He has been one of the pioneers in the area of computer animation and the integration of sound and motion.


Colloquium Topic: The Virtual World of the Computer

Computer graphics is one of the fastest growing segments of computer science involving a number of disciplines and a wide range of applications. In this talk, the speaker will give a brief overview of the field followed by an introduction to work that has been performed at the George Washington University Institute for Computer Graphics. Specifically, the talk will concentrate on motion control for computer animation using motion capture and derivation of controllers and will also present work in the field of computer-guided surgery and surgical simulations. In this work, computer graphics and virtual reality technology are applied to help surgeons train, rehearse for as surgery, and to aid during the surgical procedure.
