Computer supported work is increasingly being done out of the traditional office environment, for example whilst travelling or at home and there is a growing need to support the cooperative aspects of such work. Remote Cooperation looks at ways of improving the available communications, through the use of packet radio and compression techniques, in order to reduce the imbalance between office-based and mobile workers. It also assesses how the effectiveness of the existing communications infrastructure can be improved, by providing cooperative applications which fit within its limitations. Broadly divided into five sections - social and economic context, application domains, software technology and infrastructure, communications technology and infrastructure, working and learning from home - this volume contains contributions from both the research community and industry.
