    Towards virtual communities on the Web: Actors and audience

    Get PDF
    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. Our environment models a theatre in our hometown. We discuss attempts to let this environment evolve into a theatre community where we do not only have goal-directed visitors, but also visitors that that are not sure whether they want to buy or just want information or visitors who just want to look around. It is shown that we need a multi-user and multiagent environment to realize our goals. Since our environment models a theatre it is also interesting to investigate the roles of performers and audience in this environment. For that reason we discuss capabilities and personalities of agents. Some notes on the historical development of networked communities are included

    Social positioning: Designing the Seams between Social, Physical and Digital Space

    Get PDF
    Mobile settings are not only physically and digitally mediated; they are also inhabited by people - a social space. We argue that careful design exposing the connections, gaps, overlays and mismatches within and between physical, digital and social space allow for a better understanding and thereby mastering of the resulting combined space. Two concepts are explored in MobiTip, a social mobile service for exchanging opinions among peers: intramedia seams concerning network coverage and position technology, and intermedia seams between digitally transmitted tips and the physical, social context surrounding the user. We introduce social positioning as an alternative and complement to the current strive for seamless connectedness and exact positioning in physical space

    Options and recommandations related to further development of an Espon Cartographic Language

    In this 5th part of Espon Cartographic Language Final Report, our aim is to identify good practices, as well in the development of interactive cartographic environments such as atlases, as in innovative cartographic constructions. Our proposals target several levels:- The level of applications themselves: which functionalities have to be use, for what applications and what objectives?-The level of cartographic representations, meaning the possibilities to introduce elements of animation and interactivity in maps, depending on data and objectives: what innovations for which representation?To achieve such aims, we use two types of resources:- a collection of interactive atlases, considered as the most representative of the diversity in european statistical atlases, which we have analyzed and compared.- the collection of maps presented in Task 4, that we propose to enrich with functions of interaction and animation.The first part of Task 5 deals with recommendations, coming from a comparative analysis of european statistical atlases. These recommendations depend on the type of environment to be made (environment of visualization, analysis or exploration), and on the desired interactivity level.The second part deals with recommendations to create interactive and animated maps. They are illustrated by concrete proposals, in the form of summary datasheet.The final part deals with a comparison of computer tools that can be used to make innovative cartographic applications

    A review of data visualization: opportunities in manufacturing sequence management.

    No full text
    Data visualization now benefits from developments in technologies that offer innovative ways of presenting complex data. Potentially these have widespread application in communicating the complex information domains typical of manufacturing sequence management environments for global enterprises. In this paper the authors review the visualization functionalities, techniques and applications reported in literature, map these to manufacturing sequence information presentation requirements and identify the opportunities available and likely development paths. Current leading-edge practice in dynamic updating and communication with suppliers is not being exploited in manufacturing sequence management; it could provide significant benefits to manufacturing business. In the context of global manufacturing operations and broad-based user communities with differing needs served by common data sets, tool functionality is generally ahead of user application

    Usability dimensions in collaborative GIS

    Get PDF
    Collaborative GIS requires careful consideration of the Human-Computer Interaction (HCI) and Usability aspects, given the variety of users that are expected to use these systems, and the need to ensure that users will find the system effective, efficient, and enjoyable. The chapter explains the link between collaborative GIS and usability engineering/HCI studies. The integration of usability considerations into collaborative GIS is demonstrated in two case studies of Web-based GIS implementation. In the first, the process of digitising an area on Web-based GIS is improved to enhance the user's experience, and to allow interaction over narrowband Internet connections. In the second, server-side rendering of 3D scenes allows users who are not equipped with powerful computers to request sophisticated visualisation without the need to download complex software. The chapter concludes by emphasising the need to understand the users' context and conditions within any collaborative GIS project. © 2006, Idea Group Inc

    New technologies for urban designers: the VENUE project

    Get PDF
    In this report, we first outline the basic idea of VENUE. This involves developing digital tools froma foundation of geographic information systems (GIS) software which we then apply to urbandesign, a subject area and profession which has little tradition in using such tools. Our project wasto develop two types of tool, namely functional analysis based on embedding models of movementin local environments into GIS based on ideas from the field of space syntax; and secondlyfashioning these ideas in a wider digital context in which the entire range of GIS technologies werebrought to bear at the local scale. By local scale, we mean the representation of urban environmentsfrom about 1: 500 to around 1: 2500
