Research On Collaborative Awareness In Virtual Space Teleconferencing

Computer Supported Cooperative Work (CSCW) refers to, by means of computer and network technology, a geographically distributed group work together to accomplish a task. The technology of Cooperative work has been widely applied in various fields such as military, industry, electronic commerce, tele-medical education and collaborative scientific research. Virtual Space Teleconferencing (VST) system is an important branch of CSCW, which is often called the ultimate form of meeting. In VST system, all the participants and their stand-in will be synthesized into the virtual conference space and natural interaction and collaboration among all the participants will be achieved with strong sense of realism and immersion. Collaborative Awareness technology is one of the key technologies in VST. Collaborative sensing is to create real-world environment liked transformation mode for environment and information perception in computer supported virtual cooperative work environment so that the virtual world will be more real and the collaborative process will be more natural and efficient.In this paper, VST system is studied based on collaborative sensing and control technology. First of all, two typical perceptual models are introduced and their characteristics and shortcomings are analyzed. A task-role based collaborative sensing model for VST system is proposed and the basic structure, composition elements, level division and perception strength calculation function of this model are described. Then, based on the task-role based perceptual model, a corresponding task-role based collaborative control model is introduced. The demand of cooperative work environment is analyzed. The basic structure of the model is described. Also the tasks, roles, decomposition and scheduling algorithms are designed. Finally, the overall design of VST is discussed. The operation framework and technology roadmap of VST are introduced. According to the technology roadmap, every single module is designed, including the constitution of VST, scene generation and the process of module-driven and collaborative interaction. Moreover, the application of collaborative sensing in VST is discussed.The research in this paper is based on the project 'New Digital Funeral and Sacrifice System' which aims to solve the problems that encountered in China's Funeral Reform and provide an important direction for the second Funeral Reform. Therefore, in this paper, technology of VST and new digital funeral and sacrifice system are combined and the characteristics and structure of new digital funeral and sacrifice system are introduced. Based on the technology of VST, three-dimensional roaming module of the new digital funeral and sacrifice system is designed, which provides an important direction for its research and development.
