    Artists, along with technologists, have historically stood at the forefront of multimedia-blurring boundaries and crossing borders, penetrating the looking glass, pushing the envelope with the R&D of their creative explorations using new technologies. In the process, they redefine the very notions of both art and artist. These artists work in multiple disciplines, across platforms, creating new forms from hybrid combinations, defying the labels of definition, and inventing new languages. In most cases, the art experience-no longer passive-requires some sort of interactive participation View full abstract»

    The Advanced Information System group of the National Research Council (CNR) Computer Science Department at the Cybernetics Institute has become involved in research concerning hypermedia systems in the field of cultural heritage. This activity takes place within the three-year project “An Environment for a Virtual Hypermedia Factory” (VHF). The European Commission funded the project within the 4th RTD Framework, Information Technologies (Multimedia Systems domain). The project aims mainly to develop an integrated environment equipped with services and applications for producing, archiving, and spreading information about cultural heritage, tourism, and publishing through the Internet. This environment encourages content integration by stimulating cooperation among information providers in different but correlated knowledge domains. The paper discusses the Virtual Hypermedia Factory consortium and platform requirements View full abstract»

  • Virtual metamorphosis

    The virtual metamorphosis system lets people change their forms into any other form in a virtual scene. To realize these changes, a computer vision system estimates facial expressions and body postures and reproduces them in a computer graphics avatar in real time. We introduce three systems in order of their development: the Virtual Kabuki system, Networked Theater and “Shall We Dance?” View full abstract»

  • PML: adding flexibility to multimedia presentations

    Page(s): 40 - 52
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (284 KB)  

    In multimedia systems, designers typically link content and presentation. The paper discusses a new markup language, Procedural Markup Language (PML), which decouples content and presentation. It lets users specify the knowledge structures, underlying physical media, and relationships between them using cognitive media roles. This approach fosters modular system design and dynamic multimedia systems that can determine appropriate presentations for a given situation by allowing knowledge specification to be done separately from knowledge presentation View full abstract»

  • Digital video for the time impaired

    As we strive to advance in our jobs, our disposable time decreases. We're becoming time impaired in spite of our hunger for content. We don't have time to get the information we want. We have even less time to access the entertainment we want-at least in the old-fashioned way. Now that digital TV channels, digital video disks (DVD), and digital video home systems (DVHS) can feed our hunger for content, we need a drastic twist in the way we think of TV. We're used to the idea of displayable video and viewable TV. However, in the future we'll have to create searchable TV-similar to the concept of searchable databases. Searching on the fly, or content filtering, should enable applications such as parental control systems, commercial detection software, and selective news services while providing personalized TV experiences View full abstract»

  • Multimedia-friendly server and communication design

    Page(s): 84 - 90
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (232 KB)  

    We report on a set of projects to: design, implement, and evaluate software frameworks for providing performance assurances in emerging Internet services and real-time applications with a focus on multimedia; and design and evaluate video-on-demand (VOD) servers as an application. First we describe the Adaptware project, which investigates adaptive software for server platforms. A complementary project addresses reliable transmission of QoS-sensitive data over packet switched networks. Together, these two prongs compose an end-to-end approach to achieving flexible QoS guarantees for future Internet applications. We discuss VOD servers as a potential application of this two-pronged approach View full abstract»

  • WebDAV: a panacea for collaborative authoring?

    Page(s): 76 - 79
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (60 KB)  

    The paper discusses WebDAV (Web Distributed Authoring and Versioning) which provides the mechanism that will allow authoring of documents over the Internet. A series of extensions to hypertext transfer protocol (http), it allows not only the retrieval of Web documents, but the in-place editing of them as well. Could WebDAV represent the most significant change to authoring since the advent of the printing press? Can it really change the way we create and maintain Web sites? View full abstract»

  • FreeWalk: a 3D virtual space for casual meetings

    A meeting environment for casual communication in a networked community, FreeWalk provides a 3D common area where everyone can meet and talk freely. FreeWalk represents participants as 3D polygon pyramids, on which their live video is mapped. Voice volume remains proportional to the distance between sender and receiver. For evaluation, we compared communications in FreeWalk to a conventional desktop videoconferencing system and a face-to-face meeting View full abstract»

    In the StarWalker virtual environment, users explore a shared semantic space and collaborate with concurrent visitors. The authors consider how StarWalker's design illustrates the potential of unifying spatial models, semantic structures, and social navigation metaphors in the development of multiuser virtual environments View full abstract»
