Write a composition about the advantages and disadvantages of a virtual university. 什么是虚拟现实技术呢？简单地说，就是人们利用计算机生成一个逼真的三维虚拟环境，通过自然技能使用传感设备与之相互作用的新技术。它与传统的模拟技术完全不同，是将模拟环境、视景系统和仿真系统合三为一，并利用头盔显示器、图形眼镜、数据服、立体声耳机、数据手套及脚踏板等传感装置, 把操作者与计算机生成的三维虚拟环境连结在一起。操作者通过传感器装置与虚 拟环境交互作用，可获得视觉、听觉、触觉等多种感知，并按照自己的意愿去改变“不随心”的虚拟环境。 比如，计算机虚拟的环境是一座楼房，内有各种设 备、物品，操作者会如同身临其境一样，可以通过各种传感装置在屋内行走查 看、开门关门、搬动物品；对房屋设计上的不满意之处，还可随意改动。
Characteristics of Immersive VR The unique characteristics of immersive virtual reality can be summarized as follows:
Head-referenced viewing provides a natural interface for the navigation in three-dimensional space and allows for look-around, walk-around, and fly-through capabilities in virtual environments.
The virtual world is presented in full scale and relates properly to the human size.
Realistic interactions with virtual objects via data glove and similar devices allow for manipulation, operation, and control of virtual worlds.
Stereoscopic viewing enhances the perception of depth and the sense of space.The convincing illusion of being fully immersed in an artificial world can be enhanced by auditory, haptic, and other non-visual technologies.
Networked applications allow for shared virtual environments .
