Computer network is an important subject to students major in science and engineering. In this paper, we provide a Web-based Computer Network Learning Platform, which is built based on network technology, multimedia technology and virtual reality technology.
In view of the shortage of numerical control(NC) teaching resources and some problems such as high cost and high risk of equipment in current NC training area, with the rapid development of virtual reality, computer network and human-computer interaction technology, a feasible programme of virtual NC simulation system based on browser/server(B/S) was brought forward. Firstly, the development platforms...
According to customer individuation demand for automobile product, with the rapid development of computer network and virtual reality technology, an automobile order method based on Browser/Server and Eon Studio was presented in this paper. The framework and development environment of order system was expounded firstly. The automobile modeling and optimization, router mechanism of interaction events...
Recently, virtual reality (VR) technology has developed quickly, together with research conducted on various elemental and related technologies and research in various fields of its application. We experimented about the delay. The haptic media is very sensitive to the network delay and its jitter and packet loss. The AHP is one of methods to evaluate physical phenomena as correctness of the human...
A term virtual capacity layer concerns multilayered model of the network. That kind of models refer to networks compounded of different layers of resources where different topologies in each layer are possible. Virtual capacity (VC) layer describes a network topology which is situated directly above transport layer. This paper focuses on topology of VC layer and its influence on the dimensioning issue...
In this paper, we introduce a new idea of revision tree which can provide a flexible mechanism to store the current collaborative virtual environments (CVE) space, replay the past recorded CVE space and replace the current CVE by other past CVE space. Revision tree with hierarchical 3D structure is visualized in space and operated by users to refer the past space information using replay, revert,...
SoftMan, the virtual robot in network environment, is a kind of software Artificial Life living in computer networks. It has a humanoid structure, and simulating human, its perception system should be able to recognize perceptive objects. Enlightened by human's perception system and the "disassemble-integration" method in analyzing large systems, a cooperative classification model in SoftMan's...

We present an approach to collision detection that is appropriate for satisfying the requirements of interest management schemes used in distributed virtual environments. Such environments are characterized by their distributed deployment over a number of nodes connected via a computer network. The aim of an interest management scheme is to identify when objects that populate a simulation supported...
We present a new video browsing method for multiple videos that are taken at large-scale space for live 3D events such as soccer games. By our method, multiple viewers over a computer network can browse a live 3D event from any viewpoint and each viewer can move his/her viewpoint freely. Our algorithm consists of five steps. Our system first captures videos from multiple cameras, then extracts texture...
