Virtual Realities Dagstuhl Seminar

From 1st to 6th June 2008, the Dagstuhl Seminar 08231 Virtual Realities was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. Virtual Reality (VR) is a multidisciplinary area of research aimed at interactive human-computer mediated simulations of arti cial environments. Typical applications include simulation, training, scienti c visualization, and entertainment. An important aspect of VR-based systems is the stimulation of the human senses typically sight, sound, and touch such that a user feels a sense of presence (or immersion) in the virtual environment. Di erent applications require di erent levels of presence, with corresponding levels of realism, sensory immersion, and spatiotemporal interactive delity. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. Links to extended abstracts or full papers are provided, if available.
