In the article Virtual Reality Art: Genesis Ultimate Re-creation, VR art has the fol

7、lowing definition: Virtual reality (VR), enhanced reality (AR) and other artificial intelligence technology as a means of media to use the art form, we call it virtual reality art, referred to as VR art.The main feature of the art form is hypertext and interactivity. VR as a comprehensive manifestat

8、ion of modern technology, VR art is through the man-machine interface for visualization of complex data operations and interaction of a new form of art language, it attracts artists is important, is the art of thinking and technology tools closely And the deep penetration of the two generated by the

9、 new cognitive experience.Compared with the traditional window under the operation of the new media art, interactive and extended man-machine dialogue, VR art presents its unique advantages of the key from the overall sense Say, VR art is a new man-machine dialogue based on the interactive form of a

If the interactive device system with VR nature can set the viewer through the multi-sensory interactive channel and the process of crossing the device, the

15、re-creation. VR 藝術(shù)是伴隨著 “虛擬現(xiàn)實(shí)時(shí)代 ”的來(lái)臨應(yīng)運(yùn)而生的一種新興而獨(dú)立的藝術(shù)門類，在虛擬現(xiàn)實(shí)藝術(shù)： 形而上的終極再創(chuàng)造一文中，關(guān)于 VR 藝術(shù)有如下的定義： “以虛擬現(xiàn)實(shí) (VR)、增強(qiáng)現(xiàn)實(shí) (AR) 等人工智能技術(shù)作為媒介手段加以運(yùn)用的藝術(shù)形式，我們稱之為虛擬現(xiàn)實(shí)藝術(shù)，簡(jiǎn)稱 VR 藝術(shù)。該藝術(shù)形式的主要特點(diǎn)是超文本性和交互性。 ”“作為現(xiàn)代科技前沿的綜合體現(xiàn)， VR 藝術(shù)是通過(guò)人機(jī)界面對(duì)復(fù)雜數(shù)據(jù)進(jìn)行可視化操作與交互的一種新的藝術(shù)語(yǔ)言形式，它吸引藝術(shù)家的重要之處，在于藝術(shù)思維與科技工具的密切交融和二者深層滲透所產(chǎn)生的全新的認(rèn)知體驗(yàn)。與傳統(tǒng)視窗操作下的新媒體藝術(shù)相比，交互

16、性和擴(kuò)展的人機(jī)對(duì)話，是 VR 藝術(shù)呈現(xiàn)其獨(dú)特優(yōu)勢(shì)的關(guān)鍵所在。從整體意義上說(shuō)， VR 藝術(shù)是以新型人機(jī)對(duì)話為基礎(chǔ)的交互性的藝術(shù)形式，其最大優(yōu)勢(shì)在于建構(gòu)作品與參與者的對(duì)話，通過(guò)對(duì)話揭示意義生成的過(guò)程。藝術(shù)家通過(guò)對(duì) VR 、AR 等技術(shù)的應(yīng)用，可以采用更為自然的人機(jī)交互手段控制作品的形式，塑造出更具沉浸感的藝術(shù)環(huán)境和現(xiàn)實(shí)情況下不能實(shí)現(xiàn)的夢(mèng)想，并賦予創(chuàng)造的過(guò)程以新的含義。如具有 VR 性質(zhì)的交互裝置系統(tǒng)可以設(shè)置觀眾穿越多重感官的交互通道以及穿越裝置的過(guò)程，藝術(shù)家可以借助軟件和硬件的順暢配合來(lái)促進(jìn)參與者與作品之間的溝通與反饋，創(chuàng)造良好的參與性和可操控性 ;也可以通過(guò)視頻界面進(jìn)行動(dòng)作捕捉，儲(chǔ)存訪問(wèn)者的行為

18、ics technology, wide-angle (wide field) stereoscopic display technology, the observer head, eye and hand tracking technology, and tactile / force feedback, stereo, network transmission, voice Input and output technology. These techniques are described below.Real-time three-dimensional computer graph

19、icsBy contrast, it is not too difficult to use a computer model to produce a graphic image. If there is enough accurate model, and there is enough time, we can generate accurate images of various objects under different lighting conditions, butthe key here is real time. For example, in the flight si

20、mulation system, the image refresh is very important, while the image quality requirements are high, coupled with a very complex virtual environment, the problem becomes very difficult.ShowWhen people look around the world, because of the different positions of the two eyes, the image is slightly di

21、fferent, these images in the minds of integration, it formed a whole world around the world, this scene includes distance information The Of course, the distance information can also be obtained by other methods, such as the distance between the eyes of the distance, the size of the object compariso

22、n.In the VR system, binocular stereoscopic vision played a significant role. The two images seen by the users eyes are generated separately and displayed on different displays. Some systems use a single display, but the user to bring a special glasses, one eye can only see the odd frame image, the o

23、ther eye can only see even frame images, odd, even between the different frames is parallax It produced a three-dimensional sense.User (head, eye) tracking: In the artificial environment, each object relative to the system coordinate system has a position and attitude, and the user is also true. The

24、 user sees the scene by the users position and the direction of the head (eye) to determine.A virtual reality headset that tracks the head movement: In traditional computer graphics technology, the field of view changes through a mouse or keyboard, the users visual system and motion-aware system are

25、 separate, and use the head tracking to change the image The perspective of the users visual system and motion perception system can be linked between, feel more realistic. Another advantage is that users can not only through binocular stereoscopic vision to understand the environment, but also thro

26、ugh the head of the movement to observe the environment.In the interaction between the user and the computer, the keyboard and mouse are the most commonly used tools, but for the three-dimensional space, they are not suitable. In the three-dimensional space because there are six degrees of freedom,

27、it is difficult to find a more intuitive way to map the plane movement of the mouse into three-dimensional space of any movement. Now, there are already some devices that can provide six degrees of freedom, such as 3Space digitizer and SpaceBall space ball. Some of the more well-behaved devices are

28、data gloves and data clothing.SoundPeople can well determine the direction of the sound source. In the horizontal direction, we determine the direction of the sound by the difference in the phase difference and the intensity of the sound, since the time or distance at which the sound reaches the two

29、 ears is different. Common stereo effect is to listen to the left and right ears in different locations to record the different sounds to achieve, so there will be a sense of direction. In real life, when the head turns, the direction of the sound will change. But in the VR system, the direction of

30、the sound and the users head has nothing to do with the movement.Feel feedbackIn a VR system, the user can see a virtual cup. You can try to catch it, but your hand does not really touch the feeling of the cup, and it is possible to pass through the virtual cup surface, which in real life is impossi

31、ble. A common device for solving this problem is to install some vibrable contacts on the inner layer of the glove to simulate tactile sensation.VoiceIn the VR system, the voice input and output is also very important. This requires that the virtual environment be able to understand the human langua

32、ge and interact with people in real time. It is quite difficult for a computer to recognize a persons voice because the speech signal and the natural language signal have their multilaterality and complexity. For example, there is no obvious pause between words and words in continuous voice, the sam

33、e word, the same word by the words before and after the word, not only different people say that the same word will be different, that is, the same person will be subject to psychological, Physiological and environmental effects vary.The use of human natural language as a computer input There are tw

34、o problems, the first is the efficiency of the problem, in order to facilitate the computer to understand, enter the voice may be quite long-winded. Second is the correctness of the problem, the computer understands the voice of the method is to match the match, and no ones intelligence.虛擬現(xiàn)實(shí)是多種技術(shù)的綜合，包括實(shí)時(shí)三維計(jì)算機(jī)圖形技術(shù)，廣角(寬視野 )立體顯示技術(shù)，對(duì)觀察者頭、眼和手的跟蹤技術(shù)，以及觸覺/力覺反饋、立體聲、網(wǎng)絡(luò)傳輸、語(yǔ)音輸入輸出技術(shù)等。下面對(duì)這些技術(shù)分別加以說(shuō)明。實(shí)時(shí)三維計(jì)算機(jī)圖形相比較而言，利用計(jì)算機(jī)模型產(chǎn)生圖形圖像并不是太難的事情。如果有足夠準(zhǔn)確的模型，又有足夠的時(shí)間，我們就可以生成不同光照條件下各種物體的精確圖像，但是這里的關(guān)鍵是實(shí)時(shí)。例如在飛行模擬系統(tǒng)中，圖像的刷新相當(dāng)重要，同時(shí)對(duì)圖像質(zhì)量的要求也很高，再加上非常復(fù)雜的虛擬環(huán)境，問(wèn)題就變得相當(dāng)困難。顯示人看周圍的世界時(shí)，由于兩只眼睛的位置不同，得到的圖像略有不同，這些圖像在腦子里融合起來(lái)，就形成了一
