Abstract

A distributed virtual environment (DVE) enables geographically distributed clients to interact with each other in a simulated environment. Due to the distributed architecture of DVEs, it is generally not easy to evaluate the performance of DVEs. In this paper, we propose a consistency model based on a metric called time-space inconsistency. The model relates a human participant's perception to the characteristic parameters of a DVE. Based on the model, the performance of a DVE can be easily evaluated without the actual execution of the DVE application, which is especially useful in the designing stage of a DVE. A ping-pong game is developed to verify the proposed model. Experiment results show that the model is effective in evaluating the performance of the game.

用于评估分布式虚拟环境的一致性模型

分布式虚拟环境(distributed virtual environment, DVE)使地理上分布的客户端能够在模拟的环境中进行交互。由于分布式交换机的分布式架构，通常不容易对分布式交换机的性能进行评估。在本文中，我们提出了一个基于时间-空间不一致性度量的一致性模型。该模型将人类参与者的感知与DVE的特征参数联系起来。基于该模型，可以在不实际执行DVE应用程序的情况下轻松评估DVE的性能，这在DVE的设计阶段特别有用。开发了一个乒乓球游戏来验证所提出的模型。实验结果表明，该模型能够有效地评价游戏的性能。
