Intelligent Virtual Agents

Klappentext
This book constitutes the refereed proceedings of the 7th International Workshop on Intelligent Virtual Agents, IVA 2007, held in Paris, France, September 17-19, 2007. The 19 revised full papers and 12 revised short papers presented together with 5 invited talks and the abstracts of 32 poster papers were carefully reviewed and selected from 100 submissions. The papers are organized in topical sections on Rendering and Analysis, Culture and Identity, Behavior Models, Feedback Models, Dialogues, Applications, Evaluation, Gaze models and Emotions.
