Since the first INTERACT Conference in September 1984, the field of Human-Computer Interaction has received increasing attention from researchers and industrial practitioners, the importance of the topic now being widely recognized. Technological developments have made it possible to seek new solutions to the problem of supporting work processes by information technology and for designing the interface between user and the machine. Computers have become an everyday and common tool in the work of many people. This has motivated the development of an interdisciplinary field of research, which now appears much more established than it was a few years ago.The INTERACT forums provide the opportunity for regular presentation and discussion of new results from research and application by bringing together the various disciplines and research approaches on a worldwide basis.
