A Distributed Whiteboard for Network Conferencing
نویسنده
چکیده
Advances in network technology and research in real-time packet-switched networks have prompted the emergence of internet conferencing. While audio and video conferencing tools are readily available, shared workspaces and drawing tools have been slower to emerge. We present a design for a network conferencing whiteboard that differs in notable respects from other shared workspace prototypes. We describe its transport layer, based on IP multicasting and application level framing, and its object oriented imaging model, based on persistent PostScript graphics operations. We then propose a user interface, and finally, describe a C++ implementation based on the InterViews structured graphics library.

Design of a shared whiteboard component for multimedia conferencing
This paper reports on the development of a framework for multimedia applications in the domain of tele-education. The paper focuses on the protocol design of a specific component of the framework, namely a shared whiteboard application. The relationship of this component with other components of the framework is also discussed. A salient feature of the framework is that it uses an advanced ATM-...
متن کاملStudying video-based collaboration in context: From small workgroups to large organizations
Over the past few years, our group has developed and studied a variety of video-based prototypes to support remote collaboration. We started with a basic desktop video conferencing system with a shared whiteboard and found that it was effective in supporting a distributed group’s conversations, but that many of their attempts to contact each other were unsuccessful. We went on to build another ...
متن کاملA Mixed Reality 3D Conferencing Application
We describe a Mixed Reality conferencing application which uses the overlay of virtual images on the real world to support three dimensional remote computer supported collaborative work. Remote collaborators are represented on Virtual Monitors which can be freely positioned about a user in space. Users can collaboratively view and interact with virtual objects using a shared virtual whiteboard....

Aetive technology is emerging as one of the most promising fields in networking and distributed computing. It permits customized and more flexible control over the underlying networks. End users can systematically and strategically study and change the network behaviors by programming individual nodes of the network. The functionality of an adive network goes beyond the traditional data transmi...
متن کاملUsing symmetric distributed processing for peer-to-peer VoIP conferencing in auditory virtual environments
We present a P2P VoIP conferencing network with a symmetric distributed processing topology that we believe to be well suited for use in auditory virtual environments because it allows for multi-group communication and individual volumes per user. The network provides adaptive quality based on virtual locality while requiring significantly less bandwidth than a full-mesh topology. We also prese...
