This volume is a record of the first Eurographics Workshop on Multimedia, held at the department of Numerical Analysis and Computing Science (NADA), Royal Institute of Technology, Stockholm, April 18-19, 1991. Eurographics is the European Association for Computer Graphics. It is a non-profit organization, one of whose activities is organizing workshops to provide an interface between academic and industrial research in the field of computer graphics. The idea of holding a Eurographics workshop on multimedia was put forward at the Eurographics conference in 1989. Following the success of this first workshop, a second workshop has been announced, to take place in Darmstadt, May 4-6, 1992. The Stockholm workshop met with great interest and many good contributions were received by the program committee. There were approximately 40 participants and 23 presentations were given - so many indeed that one might characterize the workshop as a working conference - and there were many discussions focusing on the presentations. The presentations dealt with a range of topics, including the clarification of ideas about the different concepts in multimedia, object-oriented methods for multimedia, multimedia from psychological perspectives, synchronization problems in multimedia, cooperative work using multimedia, and building multimedia interfaces. The presentations were the focus for numerous discussions. There was also a small exhibition of four different multimedia systems, representing the spectrum from research prototypes to commercial products.
