Proceedings of the 4th symposium on Applied perception in graphics and visualization

This book contains the proceedings of the Fourth Symposium on Applied Perception in Graphics and Visualization, which was held in Tubingen, Germany on July 25-27, 2007. APGV is an annual event, sponsored by ACM SIGGRAPH, which brings together researchers from the fields of perception, graphics and visualization. The general goals are to use insights from perception to advance the design of methods for visual, auditory and haptic representation, and to use computer graphics to enable perceptual research that would otherwise not be possible. We received 39 full paper submissions for this year's AGPV. Each submission was reviewed by at least three members of the Program Committee, and we decided to accept 17 of these as full papers, to be presented as Oral presentations at the conference (14 as long papers, and 3 as short papers). The Proceedings also include 15 one-page abstracts describing Poster presentations. The posters include summaries of paper submissions that were not accepted for Oral presentation, as well as separate poster submissions. The Oral Papers cover a wide range of topics. We have classified the papers into four categories, corresponding to the sessions: Faces and Animation, Virtual Environments and Space Perception, Rendering and Surfaces I and II, and Images and Displays. For the first time at APGV this year we have a Keynote Speaker, Greg Ward (Dolby Canada), whose talk is entitled "Dynamic Range and Visual Perception". Greg Ward is a pioneer in global illumination and high dynamic range imaging, and his work has drawn heavily from and contributed substantially to research on human vision. We also have several other Invited Speakers: Volker Blanz (University of Siegen), Oliver Bimber (University of Weimar), Philip Dutre (University of Leuven) and Rafal Mantiuk (Max Planck Institute for Computer Science in Saarbrucken).
