This volume is a record of the Workshop on Window Management held at the Ruth erford Appleton Laboratory's Cosener's House between 29 April and 1 May 1985. The main impetus for the Workshop came from the Alvey Programme's Man Machine Interface Director who was concerned at the lack of a formal definition of window management and the lack of focus for research activities in this area. Win dow Management per se is not the complete problem in understanding interaction. However, the appearance of bitmap displays from a variety of vendors enabling an operator to work simultaneously with a number of applications on a single display has focussed attention on what the overall architecture for such a system should be and also on what the interfaces to both the application and operator should be. The format of the Workshop was to spend the first day with presentations from a number of invited speakers. The aim was to get the participants aware of the current state of the art and to highlight the main outstanding issues. The second day consisted of the Workshop participants splitting into three groups and discussing specific issues in depth. Plenary sessions helped to keep the individual groups work ing on similar lines. The third day concentrated on the individual groups presenting their results and interacting with the other groups to identify main areas of con sensus and also a framework for future work."

This volume is a record of the Workshop on User Interface Management Systems and Environments held at INESC, Lisbon, Portugal, between 4 and 6 June 1990. The main impetus for the workshop came from the Graphics and Interaction in ESPRIT Technical Interest Group of the European Community ESPRIT Programme. The Graphics and Interac tion in ESPRIT Technical Interest Group arose from a meeting of researchers held in Brussels in May 1988, which identified a number of technical areas of common interest across a significant number of ESPRIT I and ESPRIT II projects. It was recognized that there was a need to share information on such activities between projects, to disseminate results from the projects to the world at large, and for projects to be aware of related activities elsewhere in the world. The need for a Technical Interest Group was confirmed at a meeting held during ESPRIT Technical Week in November 1989, attended by over 50 representatives from ESPRIT projects and the Commission of the European Communities. Information exchange sessions were organized during the EUROGRAPHICS '89 confer ence, with the intention of disseminating information from ESPRIT projects to the wider research and development community, both in Europe and beyond.
