简单的来讲，就是通过计算机系统来创建和体验虚拟世界，而这个虚拟世界可以是现实世界的再现，亦可以是构想中的世界，用户可借助视觉、听觉及触觉等多种传感通道与虚拟世界进行自然的交互。它是以仿真的方式给用户创造一个实时反映实体对象变化与相互作用的三维虚拟世界,并通过头盔显示器（HMD）、数据手套等辅助传感设备，提供用户一个观测与该虚拟世界交互的三维界面，使用户可直接参与并探索仿真对象在所处环境中的作用与变化，产生沉浸感。

虚拟仿真具有沉浸性、交互性和构想性等特点，使人们能沉浸其中，超越其上，出入自然，形成具有交互效能多维化的信息环境。而正是由于虚拟仿真可以让使用者进行交互这一特点，可以将其作为增强教学培训和演练效果的有效手段，解决培训与演练中“三高”（高危险、高成本、高污染）与“四难“（难看到、难动作、难进入、难再现）问题。
因此，虚拟仿真目前主要应用于实践操作要求比较高的专业领域，行业下游主要是军事训练、工业设计、安全演练、技术培训等相关企业。

目前，国内比较著名的虚拟仿真企业有3Glasses、大朋DPVR、VIVE、Pico等企业，而部分高校也在开始相续建设虚拟仿真虚拟实验室供学生更好的学习，如杭州电子科技大学成立的物联网虚拟实验平台、北京化工大学成立的化工安全与装备中心都是较为著名的。

由此可见，虚拟仿真的潜力巨大，还有待我们进一步的挖掘、发展与应用。
Have you learned about virtual simulation?
In recent years, with the development of science and technology, virtual simulation technology has gradually entered people's field of vision, and this year's epidemic disaster has even more reflected the feasibility and importance of virtual simulation technology. So what is virtual simulation?
Simply put, it is to create and experience a virtual world through a computer system. This virtual world can be a reproduction of the real world or a world in imagination. Users can use various sensing channels such as vision, hearing and touch to interact with The virtual world interacts naturally. It creates a real-time three-dimensional virtual world that reflects the changes and interactions of physical objects in a simulation manner, and provides users with a three-dimensional observation of the interaction with the virtual world through auxiliary sensing devices such as head-mounted displays (HMD) and data gloves. The interface allows the user to directly participate in and explore the role and change of the simulated object in the environment in which it is located, creating a sense of immersion.
Virtual simulation has the characteristics of immersion, interactivity, and conception, which enables people to immerse in it, transcend it, and out of nature, forming a multidimensional information environment with interactive effectiveness. It is precisely because of the feature that virtual simulation allows users to interact, it can be used as an effective means to enhance the effects of teaching training and drills, and solve the "three highs" (high risk, high cost, high pollution) and high pollution in training and drills. "Four Difficulties" (hard to see, hard to move, hard to enter, hard to reproduce) problems.
Therefore, virtual simulation is currently mainly used in professional fields with relatively high practical operation requirements. The downstream industry is mainly related to military training, industrial design, safety exercises, technical training and other related en
At present, the more famous virtual simulation companies in China include 3Glasses, Dapeng DPVR, VIVE, Pico, etc., and some universities are also beginning to build virtual simulation virtual laboratories for students to learn better, such as the establishment of Hangzhou Dianzi University The Internet of Things virtual experiment platform and the Chemical Safety and Equipment Center established by Beijing University of Chemical Technology are all well-known.
It can be seen that the potential of virtual simulation is huge, and we still need to further explore, develop and apply.
