Characters are central to game narratives, yet they are nowhere near as expressive as real people. This presentation proposes steps toward bridging this gap. It will focus on techniques for creating richer, more dynamic characters in terms of social categories, emotional expression, body language, and more. Examples of AI-based systems where narratives dynamically change emotional tone, character models, and metaphors used will be given. Examples will be also given of ways to analyze how prejudice and stereotyping are sometimes built into characters. The aim is to expose attendees to new approaches to creating characters that tell effective stories, empower users and combat phenomena such as sexism, racism, and stereotyping.
