Networked Virtual Environments for Collaborative Learning
In this invited talk, I examine how the technologies of networking and desktop virtual reality can be used to enhance the quality of student learning. I use the C–VISions (Collaborative Virtual Interactive Simulations) system, developed at the National University of Singapore, as an exemplar system to help the audience appreciate the unique advantages that the technology affords for student lea...
متن کاملDeskTOP, a System based on Virtual Spaces to Support and to Promote Collaborative Learning
provides a coordination mechanism to help to maintain an interaction order among the participants and to make it more efficient. The collaborative virtual environments have become a good alternative to construct collaborative learning systems. In this paper we present DeskTOP, a collaborative virtual environment implemented on the Web to support and to promote collaborative learning in universi...
متن کاملGlobal Virtual Teams and 3D Collaborative Virtual Environments
Collaborative virtual environments for desktop PCs. are inherently interesting to use and to develop, and provide motivating and challenging capstone projects for capable students to undertake. From an educational perspective, collaboration in virtual three-dimensional spaces using avatars also adds some interesting dimensions to student learning. This paper reports upon a series of development...
متن کاملCollaborative Design Studio : a sketch - based environment to support rich distant collaboration
An increasing number of large scale projects requires that distant teams collaborate together remotely. At the same time, the current CAD tools only offer minimal support for partial and asynchronous interactions. The application we propose enables full synchronous and remote sketch-based collaborative design. This setup is a combination of a virtual desktop (a remote meeting table), a standard...
متن کاملMobile Collaborative Virtual Environments: A Paradigm Shift from Desktop to Mobile Online Communities
(ABSTRACT) There are myriad examples of virtual communities and environments available for collaborative activities. However, most of these environments are confined to the desktop and thus preclude collaboration while users are on the move. Through a scenario-based design process, this article establishes the importance of mobile collaborative environments that are readily accessible for users...
