The perception of motion is vital to behavior, survival and communication. Interdisciplinary teams
studied the perception and production of motion in virtual and real environments. One team (directed
by J. Feldman) created artificial agents who explored, foraged or fought using intelligent decision rules.
Observers could infer the agents’ intentions on the basis of features of their motions. A second team (E.
Torres) used motion-capture tools to record human actors performing complex activities (e.g., tennis
serves). The group modeled the movements, and produced realistic percepts by endowing an animated
avatar with the same models. A third team (E. Kowler) found that pursuit eye movements when viewing
one’s moving arm were evoked by signals derived from arm motor planning. Taken together, these
results show remarkable overlap in the control of the perception and production of motion. This
overlap facilitates the ability to perform complex motor tasks or to interpret motor patterns of others.
Understanding connections between the perception and production of motion is crucial in fields ranging
from the study of social interactions to the design of virtual environments.
