Abstract
To build virtual environments that are realistic, useful, and
enjoyable we must solve two important problems. First, how can we
create computational models that exhibit realistic behaviors when we
interact with them --- behaviors we can experience naturally with our
eyes, ears, and hands? Second, how can we make it easy to build such
multi-modal models of existing objects, quickly and accurately? I
will describe our work towards solving these problems.
Contact interaction is essential to create the illusion of
tangibility. I will describe new techniques for physical simulation of
contact at interactive rates, with visual deformation, contact sound
synthesis, and haptic force feedback. To construct comprehensive
multi-modal models we have developed the UBC Active Measurement
Facility (ACME), a highly programmable robotic system with a large
number of sensors and actuators. ACME provides one-stop shopping for
scanning ``reality-based'' models of shape, appearance, deformation,
sound, and contact texture.
About the Speaker
Dinesh K. Pai is an Associate Professor in the Department of Computer
Science at the University of British Columbia, a member of the
Institute of Applied Mathematics, and a fellow of the BC Advanced
Systems Institute. He's the Director of the UBC Active Measurement
Facility. He received his Ph.D. from Cornell University, Ithaca, NY.
His research interests span the areas of robotics, graphics, modeling,
and simulation. One current research focus is ``Reality-based''
modeling. Another focus is fast simulation with integrated sound,
haptics, and graphics, especially simulation of contact. See
