Mobile support in CSCW applications and groupware development frameworks

Computer Supported Cooperative Work (CSCW) is an established subset of the field of Human Computer Interaction that deals with the how people use computing technology to enhance group interaction and collaboration. Mobile CSCW has emerged as a result of the progression from personal desktop computing to the mobile device platforms that are ubiquitous today. CSCW aims to not only connect people and facilitate communication through using computers; it aims to provide conceptual models coupled with technology to manage, mediate, and assist collaborative processes. Mobile CSCW research looks to fulfil these aims through the adoption of mobile technology and consideration for the mobile user. Facilitating collaboration using mobile devices brings new challenges. Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users. This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices

The paper focuses on the protocol design of a specific component of the framework, namely a shared whiteboard application. The relationship of this component with other components of the framework is also discussed. A salient feature of the framework is that it uses an advanced ATM-based network service. The design of the shared whiteboard component is considered representative for the design as a whole, and is used to illustrate how a flexible protocol architecture utilizing innovative network functions and satisfying demanding user requirements can be developed

Proceedings of the ECSCW'95 Workshop on the Role of Version Control in CSCW Applications

The workshop entitled "The Role of Version Control in Computer Supported Cooperative Work Applications" was held on September 10, 1995 in Stockholm, Sweden in conjunction with the ECSCW'95 conference. Version control, the ability to manage relationships between successive instances of artifacts, organize those instances into meaningful structures, and support navigation and other operations on those structures, is an important problem in CSCW applications. It has long been recognized as a critical issue for inherently cooperative tasks such as software engineering, technical documentation, and authoring. The primary challenge for versioning in these areas is to support opportunistic, open-ended design processes requiring the preservation of historical perspectives in the design process, the reuse of previous designs, and the exploitation of alternative designs. The primary goal of this workshop was to bring together a diverse group of individuals interested in examining the role of versioning in Computer Supported Cooperative Work. Participation was encouraged from members of the research community currently investigating the versioning process in CSCW as well as application designers and developers who are familiar with the real-world requirements for versioning in CSCW. Both groups were represented at the workshop resulting in an exchange of ideas and information that helped to familiarize developers with the most recent research results in the area, and to provide researchers with an updated view of the needs and challenges faced by application developers. In preparing for this workshop, the organizers were able to build upon the results of their previous one entitled "The Workshop on Versioning in Hypertext" held in conjunction with the ECHT'94 conference. The following section of this report contains a summary in which the workshop organizers report the major results of the workshop. The summary is followed by a section that contains the position papers that were accepted to the workshop. The position papers provide more detailed information describing recent research efforts of the workshop participants as well as current challenges that are being encountered in the development of CSCW applications. A list of workshop participants is provided at the end of the report. The organizers would like to thank all of the participants for their contributions which were, of course, vital to the success of the workshop. We would also like to thank the ECSCW'95 conference organizers for providing a forum in which this workshop was possible

Integrating groupware technology into the learning environment

This paper presents the hard lessons learned from the introduction of groupware technology within a final‐year software engineering module. The module began in 1997 and is now in its fourth year. The paper provides a detailed account of our successes and failures in each year, and describes what the authors now feel is a successful model for integrating groupware into the learning environment. The paper is important because it provides a longitudinal study of the use of groupware within a learning environment and an insight into the key success factors associated with the use of groupware. Success factors relate not only to the technology but also to social factors such as group facilitation and social protocols, to factors associated with monitoring and assessment, and to factors related to the skills development associated with being a member of a global team

Collaborative Learning and Knowledge Transfer in Consciousness Society

Starting from the expression "workplace learning†which states that the use of personal computers at work or at school reflects learning activities and work activities which are interchangeable at individual level, this paper presents collaborative models dedicated to processes of teaching, learning, assessment and research in education. One of the most important activities is represented by computer supported collaborative learning (CSCL) which, from its occurrence, presented a special interest for researchers in informatics. CSCL is based on human-computer interaction (HCI) and on computer supported cooperative work (CSCW). CSCL promotes in turn the development of computer supported collaborative research (CSCR). Information and communications technologies represent not only a media support but, most of all, a mean for accessing resources worldwide. The development of the information technology and of the information society brought benefits both to the traditional form of education, and to the distance education represented by the assisted instruction. The evolution of the information society led to the emergence of the society based on knowledge which represents an intermediary step between information society and consciousness society, who wants to be a moral society. This article highlights the transfer of data, information and knowledge (explicit and implicit) during assisted instruction processes along with the possibility to create collaborative content in consciousness society.CSCW, CSCL, CSCR Assisted Instruction, Consciousness Society

A Java Based Multimedia Distributed Collaborative Environment over the Internet

Computer Supported Collaborative Work (CSCW) and distributed computing have been termed as the next paradigm of computing which allow users to interact and collaborate with each other seamlessly over the network. As a result, many collaborative distributed systems have been developed. Most of them have been implemented on proprietary systems instead of the Internet. Some may not provide necessary awareness for collaboration, while the rest still lack the real -world collaborative tools that are needed by the users. Therefore, there is a critical need for evaluating some of the proposed and existing systems to develop an effective collaborative distributed system that provides superior performance, simplicity and functionality. In this thesis, efforts have been focused on creating a Distributed Collaborative Environment (DCE) for efficient collaborative editing and interaction among the participating users. Firstly, the comparison and analysis of various existing collaborative systems are presented. Advantages and drawbacks of various systems are highlighted. Next, an alternative collaboration system has been developed which integrates most of the superior features of other systems while trying to avoid their drawbacks. The object-oriented design methodology is described together with the newly designed collaborative access protocol, SICAP. Finally, the implementation of the protocol on a client-server system is described. The resulting Java Distributed Collaborative Environment (JDCE) is a platform-independent collaborative system which has been developed using Java. It runs on the Internet and provides both asynchronous and synchronous collaboration. This environment has been built on top of an object-oriented layering architecture framework to achieve maximum extensibility and robustness. The system provides various services for state management, message routing and session control. No installations are required to access the system since the client application is built as a Java applet

Collaborative video searching on a tabletop

Almost all system and application design for multimedia systems is based around a single user working in isolation to perform some task yet much of the work for which we use computers to help us, is based on working collaboratively with colleagues. Groupware systems do support user collaboration but typically this is supported through software and users still physically work independently. Tabletop systems, such as the DiamondTouch from MERL, are interface devices which support direct user collaboration on a tabletop. When a tabletop is used as the interface for a multimedia system, such as a video search system, then this kind of direct collaboration raises many questions for system design. In this paper we present a tabletop system for supporting a pair of users in a video search task and we evaluate the system not only in terms of search performance but also in terms of user–user interaction and how different user personalities within each pair of searchers impacts search performance and user interaction. Incorporating the user into the system evaluation as we have done here reveals several interesting results and has important ramifications for the design of a multimedia search system

Disease surveillance and patient care in remote regions: an exploratory study of collaboration among healthcare professionals in Amazonia

The development and deployment of information technology, particularly mobile tools, to support collaboration between different groups of healthcare professionals has been viewed as a promising way to improve disease surveillance and patient care in remote regions. The effects of global climate change combined with rapid changes to land cover and use in Amazonia are believed to be contributing to the spread of vector-borne emerging and neglected diseases. This makes empowering and providing support for local healthcare providers all the more important. We investigate the use of information technology in this context to support professionals whose activities range from diagnosing diseases and monitoring their spread to developing policies to deal with outbreaks. An analysis of stakeholders, their roles and requirements, is presented which encompasses results of fieldwork and of a process of design and prototyping complemented by questionnaires and targeted interviews. Findings are analysed with respect to the tasks of diagnosis, training of local healthcare professionals, and gathering, sharing and visualisation of data for purposes of epidemiological research and disease surveillance. Methodological issues regarding the elicitation of cooperation and collaboration requirements are discussed and implications are drawn with respect to the use of technology in tackling emerging and neglected diseases

An authoring tool for structuring and annotating on-line educational courses : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

This thesis studies the design and prototype implementation of a new web-based course authoring system for the Technology Integrated Learning Environment (TILE) project. The TILE authoring system edits the course structure and allows the author to annotate the course structure with meta-data. It makes extensive use of XML technology to communicate structured data across the Internet, as well as for both local and web-side databases. The Authoring tool is designed to support development by multiple authors and has check-in and check - out, as well as version control facilities. It also provides an interface for adopting other multimedia tools such as AudioGraph. The tool has an easy-to-use graphical user interface. The technical problems that have been solved in this project include issues such as cross-platform support, drag and drop functionality using JDK l.l.8, etc. System environments, such as relational database set up, XML database set up, Java swing set up in Mac also have been discussed. The authoring system interface analysis, database analysis and function analysis have been completed for the complete the system as specified. An intermediate system, designed to a reduced specification, has been implemented as a prototype and details of this system, which can work independently of the TILE delivery system, are included. The Full TILE authoring system including InstantDB database access also has been partially implemented. The prototype application has also has been tested on the PC platform
