Call for Papers Cyberworlds are information worlds or communities created on cyberspace by collaborating participants either intentionally or spontaneously. As information worlds, they accumulate information regardless whether or not anyone is in, and they can be with or without 2D or 3D visual graphics appearance. The examples of such cyberworlds are communities created in different social networking services, 3D shared virtual environments, and multiplayer online games. Cyberworlds are closely related to the real world and have a serious impact on it, augment and sometimes replace the real life and become a significant component of real economy. The international conferences on Cyberworlds have being organized annually since 2002 with the proceedings published by Conference Publishing Services (CPS) and special issues published in multiple journals, including The Visual Computer and Springer Transactions on Computational Science. The topics covered by Cyberworlds 2013 will include but are not limited to Networked and shared virtual worlds Virtual collaborative spaces Shape modeling for cyberworlds Virtual humans and avatars Multimodal interaction and rendering Computer vision for augmented and mixed reality Cognitive informatics Brain-computer interfaces Affective computing Social computing Online communities E-learning in cyberworlds Multi-user web games Art and heritage in cyberspace, cyber-museums Cyberethics and cyberlaws Cybersecurity Welfare in cyberworlds Data mining and warehousing in cyberworlds Visual analytics in cyberworlds Contact Issei Fujishiro Cyberworlds 2013 General Chair E-mail: address.02.gif Phone&Fax: +81-45-566-1752
