Research on and applications involving collaboration in virtual environments are constantly growing in many areas of human activity, including collaborative analysis, design, development, testing, operation, production, evaluation, education, training, simulation, research, social networking, and entertainment. Characteristic to such applications is a shared computer-generated medium (virtual world) that allows for involvement and interaction of participants that may be distributed over large geographical distances. With the ongoing rapid advances in computer technology, we anticipate that collaboration in virtual environments and related research will play an increasingly more substantial role in the landscape of computer-supported cooperative work, education, and entertainment. The CoVE-2014 workshop on Collaboration in Virtual Environments – to be held as part of the 2014 International Conference on Collaboration Technologies and Systems (CTS-2014) – will focus on the human-computer interaction and software engineering research and design aspects of collaboration in various types of virtual worlds, for example in 2D and 3D simulations and games, or CAVE and other VR systems. Relevant new applications, case studies, and experiments are also actively sought after by the workshop. We invite original contributions on these topics from researchers in academia, research laboratories, the computer industry, and the users’ community. Our goal is to provide a dedicated refereed collaborative virtual environments (CVE) workshop and forum for exchanging ideas that fosters closer interaction among researchers from numerous relevant disciplines, including human-computer interaction, software engineering, artificial intelligence, computer graphics, computer architecture, communication networks, distributed processing, visual arts, music, multimedia creation, industrial design, education, business administration and management, information technology, cognitive science, psychology, sociology, and anthropology.
