    Towards Communicating Agents and Avatars in Virtual Worlds

    We report about ongoing research in a virtual reality environment where visitors can interact with agents that help them to obtain information, to perform certain transactions and to collaborate with them in order to get some tasks done. In addition, in a multi-user version of the system visitors can chat with each other. Our environment is a laboratory for research and for experiments with users interacting with agents in multimodal ways, referring to visualized information and making use of knowledge possessed by domain agents, but also by agents that represent other visitors of this environment. We discuss standards that are under development for designing such environments. Our environment models a local theatre in our hometown. We discuss our attempts to let this environment evolve into a theatre community where we do not only have goal-directed visitors buying tickets, but also visitors that that are not yet sure whether they want to buy or just want information or visitors who just want to look around, talk with others, etc. It is shown that we need a multi-user and multi-agent environment to realize our goals and that we need to have a unifying framework in order to be able to introduce and maintain different agents and user avatars with different abilities, including intellectual, interaction and animation abilities

    Towards Multi-Modal Interactions in Virtual Environments: A Case Study

    Get PDF
    We present research on visualization and interaction in a realistic model of an existing theatre. This existing ‘Muziek¬centrum’ offers its visitors information about performances by means of a yearly brochure. In addition, it is possible to get information at an information desk in the theatre (during office hours), to get information by phone (by talking to a human or by using IVR). The database of the theater holds the information that is available at the beginning of the ‘theatre season’. Our aim is to make this information more accessible by using multi-modal accessible multi-media web pages. A more general aim is to do research in the area of web-based services, in particu¬lar interactions in virtual environments

    The Mundane Computer: Non-Technical Design Challenges Facing Ubiquitous Computing and Ambient Intelligence

    Full text link
    Interdisciplinary collaboration, to include those who are not natural scientists, engineers and computer scientists, is inherent in the idea of ubiquitous computing, as formulated by Mark Weiser in the late 1980s and early 1990s. However, ubiquitous computing has remained largely a computer science and engineering concept, and its non-technical side remains relatively underdeveloped. The aim of the article is, first, to clarify the kind of interdisciplinary collaboration envisaged by Weiser. Second, the difficulties of understanding the everyday and weaving ubiquitous technologies into the fabric of everyday life until they are indistinguishable from it, as conceived by Weiser, are explored. The contributions of Anne Galloway, Paul Dourish and Philip Agre to creating an understanding of everyday life relevant to the development of ubiquitous computing are discussed, focusing on the notions of performative practice, embodied interaction and contextualisation. Third, it is argued that with the shift to the notion of ambient intelligence, the larger scale socio-economic and socio-political dimensions of context become more explicit, in contrast to the focus on the smaller scale anthropological study of social (mainly workplace) practices inherent in the concept of ubiquitous computing. This can be seen in the adoption of the concept of ambient intelligence within the European Union and in the focus on rebalancing (personal) privacy protection and (state) security in the wake of 11 September 2001. Fourth, the importance of adopting a futures-oriented approach to discussing the issues arising from the notions of ubiquitous computing and ambient intelligence is stressed, while the difficulty of trying to achieve societal foresight is acknowledged

    Incorporating languages into histories of war: a research journey

    Get PDF
    This article discusses the ways in which languages can be integrated into histories of war and conflict, by exploring ongoing research in two case studies: the liberation and occupation of Western Europe (1944–47), and peacekeeping/peace building in Bosnia-Herzegovina (1995–2000). The article suggests that three methodological approaches have been of particular value in this research: adopting an historical framework; following the “translation” of languages into war situations; and contextualizing the figure of the interpreter/translator. The process of incorporating languages into histories of conflict, the article argues, has helped to uncover a broader languages landscape within the theatres of war

    Operation Moshtarak and the manufacture of credible, “heroic” warfare

    Richard Lance Keeble argues that Fleet Street’s coverage of the Afghan conflict has served largely to promote the interests of the military/industrial/media complex – and marginalise the views of the public who have consistently appealed in polls for the troops to be brought back hom

    Propaganda

    Get PDF
    The symbolic power of the state centrally depends on managing the relationship between media and politics. At the centre of this process is the operation of propaganda. Propaganda aims to shift public perceptions of or obscure the relations of ruling. By focussing on sociological processes, myths can be dispelled about propaganda as a smoothly-oiled machine that functions through carefully calibrated ends-means deliberations. Instead, propaganda is socially shaped by informal as well as formal relations of individuals and institutions

    Lifeworld Inc. : and what to do about it

    Get PDF
    Can we detect changes in the way that the world turns up as they turn up? This paper makes such an attempt. The first part of the paper argues that a wide-ranging change is occurring in the ontological preconditions of Euro-American cultures, based in reworking what and how an event is produced. Driven by the security – entertainment complex, the aim is to mass produce phenomenological encounter: Lifeworld Inc as I call it. Swimming in a sea of data, such an aim requires the construction of just enough authenticity over and over again. In the second part of the paper, I go on to argue that this new world requires a different kind of social science, one that is experimental in its orientation—just as Lifeworld Inc is—but with a mission to provoke awareness in untoward ways in order to produce new means of association. Only thus, or so I argue, can social science add to the world we are now beginning to live in

    Facilitating open plot structures in story driven video games using situation generation

    Get PDF
    Story driven video games are rising in popularity, along with the players desire to make meaningful choice within the plot and therefore become more involved and immersed within the experience. This paper investigates the problems which arise from implementing interactive narrative within video games and potential techniques to solve those problems. The main focus of the study was the situation generation technique, used to maintain the continuity within open, emergent plot structures, using behaviour trees as a means to implement and traverse plot sequences. The ISGEngine was developed during the course of this study in order to implement and evaluate the situation generation technique
