Artificial Intelligence, Natural Language, and Simulation for Human Animation

An approach to the higher-level specification and execution of animation is described. Natural language is used to augment the animation process since verbs and their modifiers (temporal, adverbial, and spatial) offer a rich and succinct vocabulary for task control. A simulation system based on human performance models and expert systems is used to produce animation control sequences. Interactive systems assist an animator or human factors engineer to graphically simulate the task-oriented activities of several human agents. The overall organization of this project and some specific components will be discussed, including: the JACK interactive graphics interface, various human factors analyses, real-time constraint-based inverse kinematic positioning, strength models, dynamic simulation, constraint-based temporal planning, artificial intelligence task definitions, and natural language specification of tasks.
