There are subtle differences between how different
individuals execute the same motion. Often these differences are
important, both for scientific applications such as biomechanical
studies, and for artistic applications, such as dance and
animation.
My research has focused on how to apply an understanding of how
live humans and animals move to create more life-like computer
animations. We can categorize the features often missing from
computer animations as "aliveness" and "personality". By
aliveness, we mean the aspects of motion that tell us we are
observing a live being and not a machine or other inanimate
object. By "personality" we mean the aspects of motion that are
unique to a particular individual. For example, when you see a
person walking from far away, often you can tell who it is just by
how he or she walks. Taken together, we refer to these feature of
aliveness and personality as a "motion texture". Just as a piece
of cloth has a certain texture defined by its look and feel, so
does an individual's way of moving. I have been working on
methods for obtaining a motion texture from live data and using it
to assist in the creation of an animation. For a much more
thorough introduction to what I've been doing, please see the
introduction of my Ph.D. thesis.
