We describe techniques for interactively controlling bipedal articulated figures through kinematic constraints. These constraints model certain behavioral tendencies which capture some of the characteristics of human-like movement, and give us control over such elements as the figures’ balance and stability. They operate in near real-time, so provide behavioral control for interactive manipulation. These constraints form the basis of an interactive motion-generation system that allows the active movement elements to be layered on top of the passive behavioral constraints.
