Accuracy is the ubiquitous goal of dynamic simulation, in order to yield the ``correct'' motion. But for creating animation, what is really of interest is ``plausible'' motion, which is somewhat different. We discuss what we mean by plausible simulation, how it differs from ``accurate'' simulation, and why we think it's a worthwhile area to study. The discussion touches on questions of physically plausible vs. visually plausible motion, plausible simulation in a noisy or textured environment, and probability measures for motion, as well as issues for forward and inverse problems.
