The two-volume conference proceedings contain 540 papers from 30 different countries. The papers included in the program were selected on the basis of reviews done by the program committee members and by leading researchers organizing special sessions centered around topics of particular interest. The first volume "Human-Computer Interaction -- Ergonomics and User Interfaces" begins with a set of papers related to health and ergonomics issues of the physical work environment. The major part of Vol. 1 is dedicated to contributions addressing novel concepts, techniques, and studies for user interfaces and interaction techniques. A number of papers in this volume present research in usability engineering as well as methods and processes for the design and development of user interfaces.
Volume 2 "Human-Computer Interaction -- Information, Communication, and Cooperation" puts the main emphasis on the informative and communicative aspects of computer use. A larger number of contributions is concerned with computer-supported cooperation using a wide variety of different techniques.
