1、分析虚拟数控技术在教学中的重要性1虚拟现实技术简述1 virtual reality technology briefly虚拟现实技术，简单地说，就是借助于计算机技术及硬件设 备，实现一种人们可以通过视、听、触、嗅等手段所感受到 的虚拟幻境。虚拟现实作为一项尖端科技，它集成了计算机 图形技术、计算机仿真技术、人工智能、传感技术、显示技 术、网络并行处理等技术的最新发展成果，由计算机图形构 成三维数字模型，并编制到计算机中去生成一个以视觉感受 为主，也包括听觉、触觉的综合可感知的人工环境，提供给 人们通过计算机对复杂数据进行可视化操作与交互的一种 全新方式。虚拟现实的最大特点是用户可以用自然方式
2、与虚 拟环境进行交互操作，改变了过去人类除了亲身经历，就只 能间接了解环境的模式，从而有效地扩展了人们的认知手段 和领域。Virtual reality technology, in a nutshell, is with the aid of computer technology and the hardware equipment, realize a kind of people can see, hear, touch, smell, feel the virtual dreamland. Virtual reality as a cutting-edge technology,wh

4、tes a mainly visual perception,alsoincludeshearing, touchintegratedperceived artificial environment, provide to people through the computer to manipulate complex data visualization and interaction of an entirely new way. The biggest characteristic of virtual reality is the user can use the natural w
5、ay to interact with virtual environment operation, changed the human in addition to the experience in the past, can only indirectly understand environment model, which effectively expanded the peoples cognitive approach and field.2虚拟现实系统的基本类型Two basic types of virtual reality system根据用户参与虚拟现实的不同形式，可
6、把虚拟现实系统划分成四类:According to different forms of user participation in virtual reality, virtual reality system is divided into four categories:3.1桌面式虚拟现实系统3.1 desktop virtual reality system桌面式虚拟现实系统也称为简易型虚拟现实系统，它是利用 个人计算机和低级工作站进行仿真，将计算机的屏幕作为用 户观察虚拟境界的一个窗口，使用者通过键盘、鼠标便可与 虚拟环境进行交互。这种系统的特点是结构简单、价格低廉，因此应用比较广
7、泛，是一套经济实用的系统。但桌面式虚拟 现实系统会受到周围现实环境的干扰，参与者缺少完全的沉 浸，缺乏真实的现实体验。Desktop virtual reality system, also known as simple typevirtual reality system, it is the use of personal computer simulation and low-level workstation, computer screen as the user to observe the virtual realm of a window, the user through
8、the keyboard and mouse can interact with the virtual environment. The characteristics of this system is of simple structure, low cost, so the application is more widely, is a set of economical and practical system. But desktop virtual reality system will be affected by the surrounding reality enviro
9、nment interference, participants lack of fully immersed, the lack of a real practical experience.3.2 沉浸式虚拟现实系统3.3 immersive virtual reality system沉浸式虚拟现实系统是一种高级的虚拟现实系统，它提供一 个完全沉浸的体验，使用户有一种置身于虚拟境界之中的感 觉。它利用头盔式显示器或其它设备，把参与者的视觉、听 觉和其它感觉封闭起来，并提供一个新的、虚拟的感觉空间，并利用位置跟踪器、数据手套、其它手控输入设备、声音等 使得参与者产生一种身临其境、全心投入和
10、沉浸其中的感 觉。沉浸式虚拟系统是一套比较复杂的系统，它的优点是用 户全身心地沉浸到虚拟世界中去，缺点是系统设备价格昂 贵，难以普及推广。Immersive virtual reality system is a kind of advanced virtual reality system, it provides a complete immersion experience, users have a sense of place oneself in the virtual realm of. It USES the low monitors or other equipment, t
11、he participants of the visual, auditory and other sensory closed up, and provide the feeling of a new, virtual space, and use the location tracking, data glove and other manual input devices, such as sound enables the participants to produce a immersive, commitment, and the feeling of immersion. Imm
12、ersive virtual system is a complex system, it has the advantage that the user fully immersed in the virtual world, the disadvantage is that the system equipment is expensive, difficult to popularized.3.4 增强式虚拟现实系统3.5 enhance type virtual reality system增强式虚拟现实系统是把真实环境和虚拟环境组合在一起 的一种系统，它既允许用户看到真实世界，同时也
13、可以看到 叠加在真实世界的虚拟对象，这种系统既可减少对构成复杂 真实环境的计算，又可对实际物体进行操作，真正达到亦真 亦幻的境界。Reinforcement virtual reality system is the real and virtual environment together in a system, it allows the user to see the real world, also can see the stack in the real world of the virtual object, the system can not only reduce the
14、 calculation for complex real environment, but also to the actual object, really reach the state is also true.3.6 分布式虚拟现实系统3.7 distributed virtual reality system分布式虚拟现实系统是利用远程网络，将异地的不同用户联 结起来，多个用户通过网络同时参加一个虚拟空间，共同体 验虚拟经历，对同一虚拟世界进行观察和操作，达到协同工 作的目的，从而将虚拟现实的应用提升到了一个更高的境 界。Distributed virtual reality sy

16、ch will increase the application of virtual reality to a higher level.3.虚拟现实技术的基本特征3 . The basic characteristics of virtual reality technology虚拟现实技术具有以下四个基本特征：Virtual reality technology has the following four basic characteristics:沉浸性一一指用户感到作为主角存在于模拟环境中的真实 程度。虚拟现实技术是根据人类的视觉，听觉的生理心理特 点，由计算机产生逼真的三维立体图
17、像，使用者戴上头盔显 示器和数据手套等交互设备，便可将自己置身于虚拟环境 中，使用者与虚拟环境中的各种对象的相互作用，就如同在 现实世界中的一样。Indulge sex - refers to the user feel as a leading role in simulating the real environment. Virtual reality technologyis based on human visual and auditory physiological and psychological characteristics, lifelike three-dimensi
18、onal image generated by the computer, users wear a helmet mounted display and data interactive equipment such as gloves, it can be yourself in a virtual environment, the user interaction with various objects in the virtual environment, like in the real world.交互性一一指用户对模拟环境内物体的可操作程度和从环 境得到反馈的自然程度。虚拟现实
19、系统中的人机交互是一种 近乎自然的交互，使用者不仅可以利用电脑键盘，鼠标进行 交互，而且能够通过特殊头盔，数据手套等传感设备进行交 互。Interactivity - refers to the user objects operational level within the simulation environment and get feedback from the environments natural degree. Human-computer interaction in virtual reality system is a kind of close to natural
20、 interaction, the user not only can use the computer keyboard, the mouse to interact, but also through the special helmet, sensing equipment such as data glove to interact. 多感知性一一是指除了一般计算机技术所具有的视觉感知 之外，还有听觉感知、力觉感知、触觉感知、运动感知，甚 至包括味觉感知、嗅觉感知等。由于虚拟现实系统中装有视、 听、触、动觉的传感及反应装置，因此，使用者在虚拟环境 中可获得视觉、听觉、触觉等多种感知，从
21、而达到身临其境 的感。Perceptual - refers to in addition to the visual perception of computer technology, force sensing and auditory perception, perception, tactile perception, motion perception, and even taste and olfactory perception, perception. Due to see, hear, touch, are installed in the virtual reality
22、system, kinesthetic sensing and reaction device, therefore, the user in a virtual environment for visual, auditory, tactile and other sensory, thus to achieve the immersive feeling.构想性一一是指虚拟现实技术具有广阔的可想像空间，可拓 宽人类的认知范围，复合土工膜不仅可再现真实存在的环 境，也可以随意构想客观不存在的甚至是不可能发生的环 境，它不仅可实现实物虚化，还可实现虚物实化等处理。Idea sex - refe
23、rs to the virtual reality technology has a broad space to imagine, to broaden the range of human cognition, not only can represent the real environment, also can freely idea even that does not exist objectively environment may not happen, it not only can realize real blur, can realize the real and v
