VST Virtual Space Teleconferencing System Development and Application

Eyes, the doctor side of the robot's eyes can be described by three-dimensional image, while the robot's hand surgery. The field of emergency units, the virtual space conference system can instantly summon a number of experts, common injuries and to discuss treatment options and surgical implementation. 34 Virtual Space Distance Education System will be used in distance education, by constructing collaborative virtual classroom-based teaching environment, teachers and students in the same place as the same, enabling teachers and students to the teaching of natural environment in a virtual face to face exchange, to create a real, natural atmosphere of teaching,[link widoczny dla zalogowanych], teachers can prompt students to grasp the situation based on the content and depth of teaching timely adjustments, and can use virtual reality technology-related experiments, for some abstract concept to visual form students to demonstrate and elaborate, such as molecular structure, space curves; students to each other can be grouped under the coordination of teachers to discuss and carry out virtual experiments and so on. Construction of Virtual Space Teleconferencing System through multi-purpose virtual learning environment, not only to overcome the deficiencies of existing distance education system, in addition to the actual teaching environment even can not have the advantages, such as information retrieval and visualization performance, virtual model and simulation support - 44, and thus distance education is likely to become the first virtual space conference system has been widely used in the field. 4 Conclusion Virtual Space Teleconferencing System research is now just in its infancy, as a new area of research, methods and implementation techniques in the theory and other aspects need to be in-depth study. Design and implementation of a run on the computer, LAN prototype system VST. The system in accordance with the application design and system operation to achieve separation of the design structure of the system which has three operating framework, the system provides a set of standardized service interface to support different types of conferencing applications, support a variety of meeting and conference control application mode . Terminal in the virtual meeting, through a multi-screen space projection technique, half way immersion has a sense of space was constructed, realistic virtual meeting applications. All participants via video synthesis to the same way a substitute for a virtual venue, to achieve, such as body language between the participants, the natural methods of gaze perception interaction. For collaborative work, the system enables users to different roles involved in virtual conferencing application that allows groups to assist the dynamic between the participants. Participants to manipulate the input devices through a variety of three-dimensional virtual entity object, the group collaboration. But these efforts are preliminary,[link widoczny dla zalogowanych], pending further study.
