>虚拟现实技术是一种可以创建和体验虚拟世界的计算机仿真系统，具有强烈的沉浸感、交互性等特点。在多媒体展示领域，虚拟现实技术拓展了数字展示的表现方式，可以协助参观者与所展示内容之间的互动，让展示内容得到良好的传播效果。
>virtual reality (vr) is an interactive computer-generated experience taking place within a simulated environment, that incorporates mainly auditory and visual, but also other types of sensory feedback like haptic. this immersive environment can be similar to the real world or it can be fantastical, creating an experience that is not possible in ordinary physical reality.
>增强现实是一种将真实世界信息和虚拟世界信息“无缝”集成的新技术，是把原本在现实世界的一定时间空间范围内很难体验到的实体信息(视觉信息,声音,味道,触觉等),通过电脑等科学技术，模拟仿真后再叠加，将虚拟的信息应用到真实世界，被人类感官所感知，达到超越现实的感官体验。
>augmented reality is an interactive experience of a real-world environment whereby the objects that reside in the real-world are "augmented" by computer-generated perceptual information.the overlaid sensory information can be constructive or destructive and is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment.
