GROUP

Marking text in a document is a convenient way of identifying bits of knowledge that are relevant for the reader, a colleague or a larger group. Based on such markings, networks of concepts with hyperlinks to their occurrences in a collection of ...

Research into collaborative document use often concentrates on how people share document content. However, studies of real-world document practices reveal that the structures by which document corpora are organised may also, themselves, be important ...

Critiquing systems, a special kind of knowledge-based systems, can be seen as a personal assistant helping to reflect on a particular design and to improve it. They have successfully demonstrated their capability to aid users during design tasks. ...

This paper reflects on the emerging results of a long-standing ethnographic study of everyday work in a large retail Bank. While customers as economic actors have often been overlooked in studies of computer supported work they are generally and ...

The development of tools to support synchronous communications between non-collocated colleagues has received considerable attention in recent years. Much of the work has focused on increasing a sense of co-presence between interlocutors by supporting ...

Groupware applications should be tailorable to fit the requirements of dynamically evolving and differentiated fields of application. To encourage individual and collaborative tailoring activities, applications should be tailorable on different levels ...

As cooperative virtual environments have become more prominent as a means of allowing users to work together so has the need for users to understand the nature of these environments. This paper presents the development of a set of techniques to allow ...

Visual shared workspaces will be always staying on users' screens in the near future. Users will be moving frequently between their personal workspaces for personal and asynchronous work and shared workspaces for communication and synchronous ...

In this paper, we describe a collaborative system specifically designed to address problems faced by distributed (or virtual) teams. TeamSCOPE (Team Software for a Collaborative Project Environment) is a web-based work environment that has emerged from ...

This paper reports on a study of clinicians who care for diabetic patients, and on the design of an application to support their work. The clinicians' long-term activity is rooted in a series of private sessions with the patient. Clinicians exchange ...

Cooperation in time-critical and physically distributed work settings, such as air traffic control, requires extensive coordination between the involved actors. For this coordination to be efficient the controllers rely both on the comprehensive use of ...

Many manufacturing enterprises are now trying to introduce various forms of flexible work organizations on the shop floor. However, existing computer-based production planning and control systems pose severe obstacles for autonomous working groups and ...

Real-time collaborative editing systems are groupware systems that allow multiple users to edit the same document at the same time from multiple sites. A specific type of collaborative editing system is the object-based collaborative graphics editing ...

Providing undo functionality in groupware has been identified as an important, but difficult problem. Existing solutions show deficiencies like lacking generality, being too complex, being inefficient, or failing to yield acceptable results in common ...

A vital component of any application or environment is security, and yet this is often one of the lower priorities, losing out to performance and functionality issues, if it is considered at all. This paper considers a spatial approach to enabling, ...

The first users of a new technology are often engineers and enthusiasts. The functionality and interface that they find acceptable may be very different than the requirements of a more mainstream audience. This poses challenges for usability engineers ...

In this paper we describe an experimental evaluation of multimedia packages intended for use as in-house training aids within a large UK bank. We focus on the influence of different kinds of media content and of network quality of service upon subjects' ...

This paper identifies and analyzes the impacts on work practices and interdependencies in radiological work by PACS (Picture Archive and Communication System). It illustrates that when PACS was introduced not only technical devices were integrated, but ...

This paper describes Pavilion, an object-oriented middleware framework for developing collaborative web-based applications. Pavilion enables a developer to construct new applications by inheriting and extending its default functionality. Reusable and ...

Many object-oriented toolkits and frameworks for groupware development provide shared objects as a basic service. This relieves developers of a lot of problems originating from the field of distributed systems. However, there is little support on how to ...

Many companies experience that their corporate intranet is getting complex and poorly manageable. We believe that developing a model for the website, or shared information space will make the management easier and provide solutions that support ...

This paper presents a detailed evaluation on the acceptability of a range of synchronous and asynchronous collaborative tools provided within the Virtual Science Park (VSP) for group work in a learning environment. In this study, the VSP was used to ...

Oxymoron is a World Wide Web based knowledge capitalization and sharing tool that was conceived and developed by a multidisciplinary team, comprised of adult education and distributed systems professionals from France and Switzerland. Oxymoron's aim is ...

This paper describes a pilot study on the role of expectations in human-computer interaction on a decision-making task. Participants (N=70) were randomly assigned to one of 5 different computer partners or to a human partner. After completing the ...

This paper provides a comprehensive review of empirical research into user contributions to computer-mediated discourse in public cyber-spaces, referred to here as virtual publics. This review is used to build a systems model of such discourse. The ...

The effects of computer-mediated communication on social loafing in brainstorming tasks and social compensation in decision-making tasks are examined. In the first experiment, subjects performed a brainstorming task in either nominal, face-to-face or ...

This article introduces and discusses issues in the design of user interfaces for visually impaired people in the domain of virtual communities. We begin by pointing out that collaborative virtual environments provide additional means for visually ...

Automated collaborative filtering systems promote the creation of a meta-layer of information, which describes users' evaluations of the quality and relevance of information items like scientific papers, books, and movies. A rich meta-layer is required, ...

This paper addresses issues of user interface design, relating to ease of use, of handheld CSCW. In particular, we are concerned with the requirements that arise from situations in which a traditionally designed mobile computer with a small keyboard and ...

This paper demonstrates how activity theoretic concepts can be used in conjunction with an ethnographically informed approach to derive requirements on a work situation. We present a case study based on a series of collaborative design episodes, the ...
