Collaborative Virtual Environments (CVEs) are distributed virtual reality systems that allow multiple geographically distant users to communicate with each other and interact with virtual objects in a shared virtual world. Recently, there has been a growing interest in the development and use of CVEs. The design analysis of CVE systems reveals seve...

... Architecture. In this architecture, the data of the shared environment is stored at a central server ( Figure 5). The main advantage of this scheme is that it greatly simplifies the management of multiple nodes, because the central server coordinates all requests issued by multiple nodes. ...

... Lock Manager's response to requests for ownership is based on the lock status of the Object of interest and the lock policy. Ownership of an unlocked Object will be given in response to any request, while ownership request of a locked Object will be rejected (Figure 15). Figure 15: An example of ownership management in the CVE prototype system. ...

... of an unlocked Object will be given in response to any request, while ownership request of a locked Object will be rejected (Figure 15). Figure 15: An example of ownership management in the CVE prototype system. The Lock manager grants the ownership request from Node 1, while denies the request from Node 2, based on the lock policy. ...

... Also, at the application level, to maintain consistency, Local Lag and Time Warp algorithms (Khan, 2010) were adopted. In the research work (Mowafi and Caudell, 2004), spatial concurrency through token-sharing ownership management has been followed, though the virtual environment incorporates multiple interfaces including haptics, the use of tokens makes the framework applies only to a one-to-one or one-to-many architecture. ...
ASSESSMENT OF QOE AND LEARNING EFFECTIVENESS IN COLLABORATIVE
MIXED REALITY ENVIRONMENTS
This paper proposed a interface-based Virtual Tutor Agent (VTA) being able in interaction to multi users in a Problem base learning process in Collaborative virtual environments using MMOG Technology (Massively multiplayer online Game). Here it has been explained concerning two main points associated with conceptual and technology. In the conceptual problem it has been explained a concept associated with Problem based learning, where a learning process has been presented in an interface context in collaborative virtual environments, while in the technology, explained concerning MMOG Technology, among other things the use of multi agent technology, which is focused on the use of Virtual Tutor Agent (VTA) and the applications of AIML (Artificial Intelligence Markup Language), as well as Lua programming language. As for the approach used is by using a simulation method. While the contribution of this Paper is a design and implementation of Problem based learning in collaborative virtual environments in the educational process.
Project TOUCH (Telehealth Outreach for Unified Community Health) is a collaborative effort between University of New Mexico and University of Hawaii. The purpose of the project is to demonstrate the feasibility of using advanced technologies to overcome geographical barriers to delivery of medical education and to enhance the learning process within a group setting. This has led to the design and implementation of a new system that addresses the critical requirements for collaborative virtual environments: consistency, networking, scalability, and system integration. The objective of this study is to evaluate the performance of the collaborative system based on use patterns during Project TOUCH sessions.
