Summary:The article describes a system for real-time interpolated
animation that addresses some of these problems. Through creating
parameterized motions-which the authors call verbs parameterized by
adverbs-a single authored verb produces a continuous range of subtle
variations of a given motion at real-time rates. As a result, simulated
figures alter their actions based on their momentary mood or in response
to changes in their goals or environmental stimuli. For example, they
demonstrate a walk verb that can show emotions such as happiness and
sadness, and demonstrate subtle variations due to walking up or down
hill while turning to the left and right. They also describe verb
graphs, which act as the glue to assemble verbs and their adverbs into a
runtime data structure. Verb graphs provide the means for seamless
transition from verb to verb for the simulated figures within an
interactive runtime system. Finally they briefly discuss the discrete
event simulator that handles the runtime main loop
