“…In taskcentered communication systems, recording the history of the task, and the virtual workspace associated with it, is done by creating contexts out of message threads. Email communication threads are stored and reused in TaskMaster [8] and activity threads comprised of all accessed data objects are stored and maintained in the Activity Explorer prototype [26,21]. These systems accurately reflect history of a project (or task) and the various data objects used in it; contacts, email, documents, etc.…”

Research has shown that computers are notoriously bad at supporting the management of parallel activities and interruptions, and that mobility increases the severity and scope of these problems. This paper presents activity-based computing (ABC) which supplements the prevalent data-and application-oriented computing paradigm with technologies for handling multiple, parallel and mobile work activities. We present the design and implementation of ABC support embedded in the Windows XP operating system. This includes replacing the Windows Taskbar with an Activity Bar, support for handling Windows applications, a zoomable user interface, and support for moving activities across different computers. We report an evaluation of this Windows XP ABC system which is based on a multi-method approach, where perceived ease-of-use and usefulness was evaluated together with rich interview material. This evaluation showed that users found the ABC XP extension easy to use and likely to be useful in their own work.

“…Activity Explorer [36] allow a shared access to repositories of documents or artifacts in organisations. People can access the shared repository, manipulate the shared object and communicate with each other via an instant messaging style communication where they can chat and send snapshots of their work.…”

Division of labour and sharing of knowledge for synchronous collaborative information retrieval

Synchronous Collaborative Information Retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques.

“…These are systems like Unified Activity Manager [16], Activity Explorer [18], and Activity Based Computing [3]. Because these systems require users to manually create, maintain, and clean up the computational representations of activities, they provide little or no support for connecting the computer representation of activities to the real-world human activities.…”

A Novel Approach for Creating Activity-Aware Applications in a Hospital Environment

Abstract. Context-aware and activity-aware computing has been proposed as a way to adapt the computer to the user's ongoing activity. However, deductively moving from physical context -like location -to establishing human activity has proved difficult. This paper proposes a novel approach to activity-aware computing. Instead of inferring activities, this approach enables the user to explicitly model their activity, and then use sensor-based events to create, manage, and use these computational activities adjusted to a specific context. This approach was crafted through a user-centered design process in collaboration with a hospital department. We propose three strategies for activity-awareness: context-based activity matching, context-based activity creation, and contextbased activity adaptation. We present the implementation of these strategies and present an experimental evaluation of them. The experiments demonstrate that rather than considering context as information, context can be a relational property that links 'real-world activities' with their 'computational activities'.
