摘　　要：为了更好实现网络虚拟校园系统建设中人机交互功能控制,减少网络带宽以及客户端异构性的限制,虚拟校园系统中的3D图形文件应尽可能小并具有跨平台的特性,首先介绍了X3D这一新的互联网三维图形规范,通过分析和比较X3D中进行人机交互功能实现的3种技术(传感器节点技术、Script节点技术、EAI技术)的原理和方法,根据虚拟校园系统建设的需求,给出了X3D中进行人机交互的应用实例。In order to better achieve human-computer interaction in virtual campus system construction and reduce the limits in network bandwidth and heterogeneity in client,3D graphics file in virtual campus should be as small as possible and have cross-platform features.X3D,a new internet three-dimensional graphics standard,is introduced.Through an analysis and comparison of the principles and methods of the three techniques,which are sensor node technology,script node technology and EAI technology that complete human-computer interaction in X3D,and aiming at meeting the demand for virtual campus system construction,an application example of human-computer interaction in X3D is given.
