    Supervision and control of wide area transportation networks requires continuous monitoring of large data sets. Two factors complicate the process: data items are spread over a wide geographic area, but are reciprocally influenced through network links, and data types attached to network nodes belong to different categories. We describe a visualization environment that tests the joint use of multiple presentation modes, such as 3D graphics, color, and windowing, to address both factors. View full abstract»

    The IEEE P802.11 committee developed the 802.11 Wireless LAN standard to cover wireless networks for fixed, portable, and moving stations within a local area. This standard addresses the need for wireless connectivity to stations, equipment, or automatic machinery that requires rapid deployment and may be portable, handheld, or mounted on moving vehicles. It can function totally wireless or connected to a wired network. Most people familiar with the standard expect to use it in providing wireless networks for personal computers or stations connected to the global wired infrastructure through access points. Now that the 802.11 standard is finally here, it will energize the wireless LAN market and result in the proliferation of low cost wireless connectivity in the office and home. Study groups are working on higher rates at 2.4 GHz and at 5 GHz for future inclusion into the standard. These higher rates will make it even more practical to employ this standard for multimedia traffic View full abstract»

    Real-time collaboration systems, in which participants share multimedia documents and applications, have attracted interest for many years. The JETS system provides a generic multimedia telecollaboration framework that enables sharing of Java applets through the Internet. Experimentation with JETS revealed practical design and implementation issues, as well as the essential requirements of such systems View full abstract»

    In conventional video-on-demand (VoD) systems, compressed digital video streams are stored in a video server for delivery to receiver stations over a communication network. This article introduces a framework for the design of parallel video server architectures and addresses three central architectural issues: video distribution architectures, server striping policies, and video delivery protocols View full abstract»

    Burgeoning consumer products and services provided through cable, television, and the World Wide Web (WWW) make it challenging for consumers to organize and use their home entertainment and information centers. Assuming that this large amount of home entertainment multimedia information will come to consumers' homes through a television or a television-like device, the Spatial Browsing project explores a 3D interface solution to multimedia database browsing and searching. Philips Research in Briarcliff, New York is developing various algorithms for browsing and retrieving information in large multimedia databases. As a design research effort, the Spatial Browsing project further augments the available in-house technology in developing user interface design concepts for interacting with such databases View full abstract»

  • Similarity retrieval of trademark images

    The Artisan system retrieves abstract trademark images by shape similarity. It analyzes each image to characterize key shape components, grouping image regions into families that potentially mirror human image perception, and then derives characteristic indexing features from these families and from the image as a whole. We have evaluated the retrieval effectiveness of our prototype system on more than 10,000 images from the UK Trade Marks Registry View full abstract»

    Virtual Stage is an extended karaoke system based on virtual reality technology. A participant becomes the main character in an interactive music video. While singing along with the song played by Virtual Stage, the participant uses body movements to interact with the virtual characters, which reside in a virtual environment and behave intelligently. In Virtual Stage, the participant's video image, grabbed by a video camera, is composited with the rendered image of the 3D virtual environment. Participants will see the realistic video image of themselves and get a false feeling of immersion, as if existing in the VE View full abstract»

  • Curious learning, cultural bias, and the learning curve

    Today's interactive installations are characterized by simplistic feedback mechanisms, limited underlying databases of content, and very little autonomous intelligence. Yet even these rudimentary systems provide great opportunities for curious learning, surprise, and serendipitous discovery. They also serve as a social nexus. The interpersonal, back-channel communications and ancillary activities of the audience, which currently remain largely unsensed and unprocessed, can be just as important as the primary authored experience. The key to accessing and communicating larger perceptions in the digital age may well lie in the collective social activities that occur within the context of shared narratives. The exchanges and experiences of group exploration and discovery, communal curious learning promises rewards far beyond the mere enjoyment of story and the instant gratifications of an individual's remote control View full abstract»

  • Using MPEG-2 video at the Getty Museum

    Today museums find themselves at a crossroad. The traditional approach of designing museum exhibits as static displays must be reconciled with the technology people face in the everyday world. We are bombarded by digital information, and media sources are increasingly geared to shorter attention spans. As a result, we expect more interactivity and technology even in leisure pursuits such as visiting an art museum. To hold the public's interest, museums must enhance the user experience, they must embrace the digital age. When the new J. Paul Getty museum in Los Angeles opened in December 1997, a new multimedia experience for visitors called ArtAccess debuted. The paper discusses the ArtAccess system which lets visitors find additional information about the museum's collections View full abstract»
