Intelligent Virtual Agents : 8th International Conference

Welcome to the Proceedings of the 8th International Conference on Intelligent Virtual Agents, which was held on September 1-3, 2008 in Tokyo, Japan. - telligent virtual agents (IVAs) are autonomous, graphically embodied agents in a virtual environment that are able to interact intelligently with human users, otherIVAs, andtheirenvironment. TheIVAconferenceseriesisthemajorannual meeting of the intelligent virtual agents community, attracting interdisciplinary minded researchers and practitioners from embodied cognitive modeling, art- cial intelligence, computer graphics, animation, virtual worlds, games, natural language processing, and human-computer interaction. The origin of the IVA conferences dates from a successful workshop on - telligent Virtual Environments held in Brighton, UK, at the 13th European Conference on Arti?cial Intelligence (ECAI 2008). This workshop was followed by a second one held in Salford in Manchester, UK in 1999. Subsequent events took place in Madrid, Spain in 2001, Irsee, Germany 2003 and Kos, Greece in 2005. Starting in 2006, IVA moved from being a biennial to an annual event and became a full-?edged international conference, held in Marina del Rey, Calif- nia, USA in 2006, and Paris, France in 2007. From 2005, IVA also hosted the Gathering of Animated Lifelike Agents (GALA), an annual festival to showcase the latest animated lifelike agents created by university students and academic or industrial research groups.
