  • Multimedia technology and 3D environments used in the preservation and dissemination of the portuguese cultural heritage
    Publication . Marcos, Adérito; Bernardes, Paulo; Sá, Vítor
    Cultural heritage is an extremely valuable set of materiality, traditions and knowledge from the Past that should be used to better understand the Past itself. However, even nowadays there are still some difficulties to manage, preserve and disseminate cultural heritage sites. The usage of multimedia technology and 3D environments in cultural heritage has reduced these difficulties; nonetheless, there are still some remaining problems. In the last years, some multimedia technology and 3D environments have been applied to the cultural heritage in Portugal. A few of them are used for scientific research purposes and others are used for dissemination purposes. In this article, the authors will refer to some representative Portuguese case studies using Virtual Environments to maintain, preserve and promote Cultural Heritage. A critical reading of these projects will be made in order to stress out their success and to point out their weaknesses and limitations.

  • Supporting information visualization through topic maps
    Publication . Marcos, Adérito; Oliveira, Alexandre Rocha; Malgueiro, Octávio; Grave, Luís
    We are living a phenomenon of accelerated information production with different accessing sources. Hence users are faced with a growing problem: accessing (navigation) and filtering specific information contained in large datasets, which are increasing in size. Procedures such as data filtering and gathering are now simplified through a new concept known as Topic Maps. The application of Virtual Reality technologies enables to present and interact with multidimensional information in a 3D space. In this paper we present INSPHERE, a new visual metaphor for information visualization,based on both, Virtual Reality techniques, and “geographical information maps” provided by Topic Maps.
