Collaboration in Virtual Environment (VE) is more often considered on an intra world mode i.e. users collaborate in the same single world. However, collaboration may also be considered on a inter worlds basis i.e. users collaborate from several possibly different worlds Thus, the interoperability between heterogeneous distributed virtual environments is one of the main problem Virtual Reality w...

The need for collaboration and cooperation across a distance is becoming equal to that between a co-located team. This means that cooperative working must be supported by systems that allow natural social human communication and interaction. A goal of telecollaboration is to reproduce the effectiveness of co-located teamwork across a distributed team. Although many of today’s systems support co...

A virtual environment is an interactive, head-referenced computer display that gives a user the illusion of presence in a virtual world. Two most significant differences between a virtual environment and a more traditional interactive 3D computer graphics system are the extent of the user's sense of presence and the level of user participation that can be obtained in the virtual environment. Ov...

This paper explores whether motoric skills acquired within a virtual training environment can be successfully transferred to the real world by comparing a virtual environment with a traditional learning environment. Specifically, a system for learning juggling with virtual balls was designed with a focus on approximating natural interaction. We propose a method of evaluating the acquisition and...

Adapting virtualization concepts to satisfy network telecommunication challenges receives more and more attention. The virtual network environment is formed by the amount of bounded virtual resources provided by physical network equipments. Deploying virtual network infrastructure has recently caught more research interests due to its flexibility and manageability. However, virtual network depl...
