This book constitutes the refereed proceedings of the 9th International Conference on Intelligent Virtual Agents, IVA 2009, held in Amsterdam, The Netherlands, in September 2009.
The 19 revised full papers and 30 revised short papers presented together with 35 poster papers, three keynote talks, and 7 GALA papers were carefully reviewed and selected from 104 submissions. The papers are organized in topical sections on personality and memory, gesture and bodily behavior, evaluation, facial expression and gaze, culture, affect and empathy, agents in virtual worlds and games, tools and motion capture, and speech and dialogue.
