    We depend on, and remain overloaded by vast amounts of information. Immersed in a chaotic sea of global data, we must organize this information so that we can interact intuitively and without anxiety from overload or confusion. Enter the architect. Architecture and digital media today, particularly virtual reality technologies, integrate in many ways. Virtual reality promises new venues for design... View full abstract»

    A classroom is equipped with strategically placed cameras to show the instructor, a zoomed view of material chosen by the instructor, the board, and all students in the class. Enough cameras provide different views to closely observe all activities of interest in the classroom. The board itself may be electronic-a computer display as well as a tablet used for input to a computer. The combined syst... View full abstract»

    A bridge between ISLAN16-T and ATM networks, where all multimedia networking technical requirements can be addressed, lets multimedia applications run between users residing across local area and wide area connections. We discuss a bridging method for transmitting integrated audio, video, and data for multimedia applications spanning ISLAN16-T in the local area network and ATM in the wide area net...

  • Multimedia in the ODP-RM standard

    Publication Year: 1997, Page(s):68 - 73
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (80 KB)

    To coordinate the various standards, we need a framework or architecture that covers many aspects of distributed systems without specifying implementation details. The International Standardization Organization (ISO), realizing the growing importance of standardizing distributed systems, initiated the Open Distributed Processing (ODP) standardization activity in 1987. The ODP reference model (ODP-... View full abstract»

    As the technology matures, we face new lessons in frustration. One serious dilemma facing tool design is that, to be profitable, a tool must support the broadest possible diversity of users. This mindset has largely yielded dumb, monolithic, use-one-at-a-time tools. However, we are about to witness a profusion of complex tool systems wherein several autonomous tools simultaneously cooperate to ass... View full abstract»

    Recent advances in distributed systems and transportable software and increasing demand for better quality of service (QoS) control in multiservice networks are driving a reexamination of network software architectures. We established the Comet (Control, Management, and Telemedia) Group at Columbia University's Center for Telecommunications Research to provide comprehensive understanding of networ...

  • Image-based virtual world generation

    The methodologies introduced here generate photographically realistic 3D worlds from 2D photographic images instead of from 3D geometrical models. If we call conventional methods “algorithm intensive”, these methods are “data intensive”. Several prototype systems, including the Virtual Dome and Camera with GPS, serve as examples. Of course, both types have their advantages,... View full abstract»

  • A taxonomy for networked virtual environments

    We discuss virtual environments in the context of how to distribute network communications, views, data, and processes while emphasizing those aspects critical to scaling environments. Systems that demand strong data consistency, causality, and reliable communications while supporting real-time interaction are not likely to scale very well. Furthermore, geographically dispersed systems require hig... View full abstract»

    Virtual reality systems use digital models to provide interactive viewing. We present a 3D digital video system that attempts to provide the same capabilities for actual performances such as dancing. Recreating the original dynamic scene in 3D, the system allows photorealistic interactive playback from arbitrary viewpoints using video streams of a given scene from multiple perspectives View full abstract»

    A new visual medium, Virtualized Reality, immerses viewers in a virtual reconstruction of real-world events. The Virtualized Reality world model consists of real images and depth information computed from these images. Stereoscopic reconstructions provide a sense of complete immersion, and users can select their own viewpoints at view time, independent of the actual camera positions used to captur...
