Proceedings of the 1st Symposium on Applied Perception in Graphics and Visualization, APGV 2004, Los Angeles, California, USA, August 7-8, 2004

Three years ago, when a small group of us gathered in Snowbird for a "campfire" on Graphics and Perception, there was a certain air of excitement that things were getting started. Last year .s record turnout at the Graphics and Perception Birds of a Feather meeting at SIGGRAPH confirmed the growing interest in this area, and the realization that perception is playing an increasingly important role in graphics and visualization. Soon after the BOF, at the SIGGRAPH .03 reception, we learned of the opportunity to hold a symposium on applied perception co-located with SIGGRAPH .04. A year to get organized is not a very long time in this busy world we live in. We scrambled to try to bring together everyone we thought would like to be involved, and even managed an impromptu meeting outside the conference center. Many phone calls and emails later, and our committee began to emerge. We are extremely grateful to everyone who helped make this a reality.Our goal for this symposium is to have it serve as an inclusive forum where researchers working at the intersection of perception, graphics and visualization can come together to share ideas and results. We hope to provide a great opportunity for people not only to acquire new knowledge, but also to seek new partnerships and collaborations. Working together can only help us all.We are pleased to present the Proceedings of the First Symposium on Applied Perception in Graphics and Visualization (APGV .04). We received 38 paper submissions in response to the call for participation. Manuscripts were received from both the perception and from the graphics research communities. Several teams of authors represented active interdisciplin-ary efforts. A wide range of topics were treated . including color, shape, motion, distance judgments, virtual reality, and haptics, as well as application areas such as product design and medicine. Each paper received three to four reviews by members of the international program committee. We originally planned a somewhat smaller program, but the overall qual-ity of the submitted work was very high. In the end we made some difficult choices and accepted 21 of the papers.We also issued a call for posters, and received numerous submissions treating diverse problems. Included here are the abstracts of the posters accepted for the Symposium.
