From the Conference Chair

Welcome to ICAD 2000! We are pleased that researchers and professionals from around the world have come together here in Atlanta to share knowledge and develop common interests in the rapidly advancing field of audio. This year's conference seeks to combine both technological and research advances with creative and novel applications of audio in areas ranging from Assistive Technologies to Psychoacoustics, from Sonification to Immersive Environments. We have programmed a special concert that will introduce a number of music and audio technologies to the ICAD Community, including some exciting music interface developments.

We are very pleased to have two distinguished keynote speakers; visionaries who have helped to shape not only their own primary fields of endeavor, but through their unique and multifaceted vision, have aided substantially in the growth and advancement of numerous other disciplines as well. R. Murray Schafer, internationally known as a composer, educator, environmentalist, scholar and provocateur, has had an enormous effect on several generations. In addition to a decade of teaching in the experimental Communications Centre at Simon Fraser University, Schafer founded the World Soundscape Project, documented in his book "The Tuning of the World." In this seminal writing, Schafer united the social, scientific and artistic aspects of sound and introduced the concept of acoustic ecology. Schafer was the first winner of the prestigious Glenn Gould Prize for Music and Communication as well as the Molson Award for his distinctive service. Dr. James Foley is well known in the Computer Graphics world, co-authoring three landmark books and serving in editorial capacities for the ACM Transactions on Graphics, Computers and Graphics and Presence. The Founding Director of the interdisciplinary Graphics, Visualization and Usability Center in Georgia Tech's College of Computing, Foley later joined Mitsubishi Electric as Director of MERL and became Chairman and CEO of Mitsubishi Electric Information Technology Center America in 1998. He is currently Executive Director and the State of Georgia's Yamacraw Project and Professor at the Georgia Institute of Technology.

We are very fortunate to have the support and encouragement of Dr. Michael Cummins, CEO of GCATT, and his excellent staff and facilities team. Additionally the support and cooperation of the Georgia Institute of Technology, its College of Architecture and Department of Music have made it possible for the ICAD Community to gather here in Atlanta. Further thanks to the Atlanta audio community and the panelists who have agreed to share their time and expertise with ICAD. On behalf of all of us who have worked behind the scenes to forge ICAD 2000, I wish you a most empowering and enjoyable ICAD Conference experience.

From the Program Chair

It has been a distinct honor to serve as program chair for ICAD 2000. The task of collecting, distributing, and selecting papers, posters, and demos for presentation was somewhat daunting. This is partially because of the quality of the research covered by the authors who submitted abstracts. It is also because of the breadth and scope of the research areas covered under the ICAD umbrella. But the pleasure of bringing engineers, programmers, scientists, doctors, military officers, musicians, and designers together to discuss the common area of sound at the human interface makes it worthwhile indeed. I wish to thank James Oliverio, Russell Storms, Jarell Pair, and James Ballas for their help in putting together the program. I also thank the ICAD board and the sponsors of the conference. I thank the paper reviewers for rendering their honest and helpful comments on the submitted papers. Finally, I thank the ICAD community for submitting material and presentations, and for their attendance at this year's conference.

About the Paper Selection Process

Extended abstracts (four-six pages) of papers were submitted electronically in four categories of short paper, long paper, poster, or demonstration. All papers were reviewed by four expert reviewers (familiar with the subject area and keywords of the paper). They were asked to evaluate based on the following criteria: Is the work new and important? Is it best presented at ICAD (as opposed to another forum)? Are the relevent references cited? Is the paper well written and formatted well? Rank the paper from 1 (do not accept) to 5 (must accept). Scores were tabulated and used to determine the papers which were accepted for presentation at ICAD 2000.
