This article describes a technique for Large Scale Virtual Environments (LSVEs) partitioning in hexagon cells and using portal in the cell interfaces to reduce the number of messages on the network and the complexity of ...

The development of large-scale distributed virtual environments deals with restrictions imposed by the infrastructure of communication systems. The scalability in those systems is an important issue to consider on designing ...

In this work, we propose a solution to solve the scalability problem found in collaborative, virtual and mixed reality environments of large scale, that use the hierarchical client-server model. Basically, we use a hierarchy ...

The use of graphical objects three-dimensional (3D) multimedia applications is gaining more space in the media. Networks with high transmission rates, computers with large processing and graphics boost and popularize such ...

Navigating is a complex cognitive task that places high demands on spatial abilities, particularly in the absence of sight. Significant advances have been made in identifying the neural correlates associated with various ...

Grid computing has been defined as an infrastructure integrator of distributed resources. Although it is already used on a large scale in many areas, this type of computational infrastructure is still an area of active ...

Computer based video games are receiving great interest as a means to learn and acquire new skills. As a novel approach to teaching navigation skills in the blind, we have developed Audio-based Environment Simulator (AbES); ...

Pesquisas utilizando virtualização de hardware vêm sendo feitas em diversas áreas dentro da Ciência da Computação. A criação de ambientes virtuais com essa tecnologia pode ser implementada utilizando-se poucos recursos ...
