Imperatives for Virtual Humans
  Seemingly since the inception of virtual humans, there has been an effort to
make their behaviors more natural and human-like. In additions to improving
movement's visual quality, there has been considerable research focused on
creating more intelligent virtual characters. This paper presents a framework
inspired by natural language constructs that aims to author more reasonable
virtual human behaviors using structured English input. We focus mainly on
object types and properties, quantifiers, determiners, and spatial relations.
The framework provides a natural, flexible authoring system for simulating
human behaviors.
