DIVA, a novel environment for group work, is presented. This prototype virtual office environment provides support for communication, cooperation, and awareness in both the synchronous and asynchronous modes, smoothly integrated into a simple and intuitive interface which may be viewed as a replacement for the standard graphical user interface desktop. In(More)
Supporting the cooperation of people in large organizations which are distributed geographically is one of the great challenges for the CSCW research. With POLIKOM, the German Federal Ministry of Education, Science, Research, and Technology launched a framework in which telecooperation applications will be developed to support the distributed government in(More)
Transparenz über die Aktivitäten anderer Nutzer ist entscheidend für einen erfolgreichen Einsatz von kooperationsunterstützenden Systemen. Beim Entwurf transparenzfördernder Systeme sind neben den funktionalen Anforderungen auch soziale, rechtliche und organisatorische Fragestellungen zu berücksichtigen. Die vorliegende Arbeit beschreibt, ausgehend von(More)
This paper investigates design issues which support awareness in collaborative environments. The work we present is part of the POLITeam project, an ongoing research effort aimed at the development of electronic tools to support the cooperation of German government sites distributed between Bonn and Berlin. The paper addresses social, ethical, legal, and(More)
In the context of the POLIKOM research program novel telecooperation tools to support the distributed German government are being developed. POLITeam is one of the projects resulting from this program, aiming at the development of a system supporting cooperation in large, geographically distributed organizations. Main area of research is asynchronous(More)
Presenting the activities of others at the user interface — thereby providing awareness — a is crucial aspect of CSCW systems. However, this problem is often neglected by existing designs. This paper discusses design requirements, introduces a notification design framework and describes the functionality ofPoliAwaC, a groupware client aimed specifically at(More)
The idea of a “common artefact” is a useful metaphor for the design of CSCW systems. Our ACCT model of a common artefact describes structural elements that provide awareness about the work of others. The ACCT model identifies actors, contents, conversations, and tools as the central components of a common artefact, arranged on a shared background. The(More)
Conventions are an important part of articulation work. They are a means to merge the various perspectives and workstyles that are involved in handling shared objects in CSCW. We report on convention use with a groupware system used in a government ministry. Our findings suggest that defining, establishing, and following conventions is aided by the(More)
