Avatars, People, and Virtual Worlds: Foundations for Research in Metaverses

Metaverses are immersive three-dimensional virtual worlds in which people interact as avatars with each other and with software agents, using the metaphor of the real world but without its physical limitations. The ubiquitous availability of high speed Internet access has spurred enormous interest in virtual worlds like Second Life and World of Warcraft, both in terms of user gaming and as a new technological platform for global virtual collaboration. These environments have potential for richer, more engaging collaboration, but their capabilities have yet to be examined in depth. Of particular interest in this paper is the use of metaverses for virtual team collaboration. We develop a conceptual model for research in metaverses that is based on five key constructs: (1) the metaverse itself, (2) people/avatars, (3) metaverse technology capabilities, (4) behaviors, and (5) outcomes. We present an in-depth characterization of metaverse technology capabilities from a socio-technical view that recognizes the potential for variation in emergent interaction and in outcomes. Example propositions and a discussion of key issues and challenges show how the model can be used to further research and practice in virtual teams in the context of these new environments

Web-CCAT: a Collaborative Learning Environment for Geographically Distributed Information Technology Students and Working Professionals

This paper describes the underlying concepts, architecture, and design of a Web-enabled CyberCollaboratory (Web-CCAT) for geographically distributed information systems students and working professionals. The primary objectives for Web-CCAT are (1) to provide the opportunity to participate in and enjoy the benefits of cooperative learning without having to coordinate meeting times or come to campus; and (2) to provide a more technologically enriched collaborative environment than is possible in a traditional face-to-face classroom. To meet these objectives, multi-user, collaborative software tools and procedures were designed for use in the asynchronous mode of communication. Web-CCAT is implemented as a tool kit of commercially available applications coupled with software developed at the University of Illinois at Springfield. The system became operational in January 1999

The CSCW paradigm for software development

People work together to solve a wide variety of problems using different forms of cooperation for each class of problem. Modern technology is complex, and therefore it is unusual for an individual to attempt the development of a major project single-handedly. In an attempt to provide computer-based support for the problems that arise when two or more people attempt to cooperate to perform a task or solve a problem, the area of Computer Supported Cooperative Work (CSCW) becomes relevant. The software development process almost invariably involves cooperation that crosses group, professional, and subcultural boundaries. The complexity of software development demands that highly integrated groups of analysts, designers, and users are involved in the process. Many development activities may occur concurrently. The area of CSCW and advanced information technology, with its enormous capabilities for transmitting and storing information, holds considerable promise for the software development process.ComputingM.

Design Ltd.: Renovated Myths for the Development of Socially Embedded Technologies

This paper argues that traditional and mainstream mythologies, which have been continually told within the Information Technology domain among designers and advocators of conceptual modelling since the 1960s in different fields of computing sciences, could now be renovated or substituted in the mould of more recent discourses about performativity, complexity and end-user creativity that have been constructed across different fields in the meanwhile. In the paper, it is submitted that these discourses could motivate IT professionals in undertaking alternative approaches toward the co-construction of socio-technical systems, i.e., social settings where humans cooperate to reach common goals by means of mediating computational tools. The authors advocate further discussion about and consolidation of some concepts in design research, design practice and more generally Information Technology (IT) development, like those of: task-artifact entanglement, universatility (sic) of End-User Development (EUD) environments, bricolant/bricoleur end-user, logic of bricolage, maieuta-designers (sic), and laissez-faire method to socio-technical construction. Points backing these and similar concepts are made to promote further discussion on the need to rethink the main assumptions underlying IT design and development some fifty years later the coming of age of software and modern IT in the organizational domain.Comment: This is the peer-unreviewed of a manuscript that is to appear in D.

Artificial Intelligence Research Branch future plans

This report contains information on the activities of the Artificial Intelligence Research Branch (FIA) at NASA Ames Research Center (ARC) in 1992, as well as planned work in 1993. These activities span a range from basic scientific research through engineering development to fielded NASA applications, particularly those applications that are enabled by basic research carried out in FIA. Work is conducted in-house and through collaborative partners in academia and industry. All of our work has research themes with a dual commitment to technical excellence and applicability to NASA short, medium, and long-term problems. FIA acts as the Agency's lead organization for research aspects of artificial intelligence, working closely with a second research laboratory at the Jet Propulsion Laboratory (JPL) and AI applications groups throughout all NASA centers. This report is organized along three major research themes: (1) Planning and Scheduling: deciding on a sequence of actions to achieve a set of complex goals and determining when to execute those actions and how to allocate resources to carry them out; (2) Machine Learning: techniques for forming theories about natural and man-made phenomena; and for improving the problem-solving performance of computational systems over time; and (3) Research on the acquisition, representation, and utilization of knowledge in support of diagnosis design of engineered systems and analysis of actual systems

The role and value of ethical frameworks in software development

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Software development is notorious for failure, typically defined as over budget, late delivery and/or poor quality of new information systems (IS) on project completion. The consequences of such failure can be enormous, particularly financially. As such, there is consensus by practitioners and academics alike that this practice is unacceptable. Yet with a variety of accepted development methods and tools available for use by software developers and project managers, there is still no significant reduction in the size or frequency of failure reported. In an attempt to understand the conflicts which arise in the development environment in which developers and project managers must operate, the research area is the role and value of ethics in the development of managed software projects. A definition of ethics in this context was provided by the IEEE/ACM Code of Ethics. Research was additionally conducted to understand how other professions and business areas define and enforce ethics in their respective working environments. These were (UK) Law, Finance, Retail and, law practice in the European Union. Interpretive research was then conducted to enable software development practices to be understood from the view of developers and project managers in industry. Unethical practices were then identified in a large IT company based in west London via a single, six month in-depth case study, with the data collected analysed via a series of repertory grids. Analysis and triangulation of the data collected via interviews, document analysis and observations led to an improved understanding of the causes of the unethical practices found. Conclusions and recommendations are then provided relating to implications for (a) the company participating in the research, (b) the application of the IEEE/ACM Code in industry (c) theory for ethicists

An adaptive environment for personal information management

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This dissertation reports the results of research into the provision of adaptive user interfaces to support individuals in the management of their personal information. Many individuals find that they have increased responsibility for managing aspects of their own lives, including the information associated with their jobs. In contrast with traditional approaches to information management, which are generally driven by organisational or business requirements, the requirements of personal information management systems tend to be less rigidly defined. This dissertation employs research from the areas of personal information management and adaptive user interfaces - systems which can monitor how they are used, and adapt on a personal level to their user - to address some of the particular requirements of personal information management systems. An adaptive user interface can be implemented using a variety of techniques, and this dissertation draws on research from the area of software agents to suggest that reactive software agents can be fruitfully applied to realise the required adaptivity. The reactive approach is then used in the specification and development of an adaptive interface which supports simple elements of personal information management tasks. The resulting application is evaluated by means of user trials and a usability inspection, and the theoretical architectures and techniques used in the specification and development of the software are critically appraised. The dissertation demonstrates an application of reactive software agents in adaptive systems design and shows how the behaviour of the system can be specified based on the analysis of some representative personal information management tasks.EPSRC (Award Reference Number 95700906
