| dc.description.abstract | We describe an innovative system for authoring expressive, fully autonomous interactive characters. The focus of our work is creating a system to allow rich authoring that captures as much of the artistic intent of the author in procedural form as we can, and that provides automatic support for expressive execution of that content. The system is composed of two parts: (1) a programming language with unusual language features including concurrency, reflection, backtracking, continuously monitored expressions, and a model of emotion, that was created for the expression of interactive self-animating characters; and (2) a motion synthesis system that combines hand-animated motion data with artistically authored procedures for generalizing the motion while preserving the artistic intent. This system has been used to create over a dozen interactive characters, which have been shown at juried venues, as well as being deployed commercially. We describe how artistic qualities important to interactive characters are encoded and supported using this system, and demonstrate the system with an implemented interactive character. | en_US |
