　　vr技術(shù)特點(diǎn)

　　VR art is a new and independent art category that comes with the advent of "virtual reality". In the article "Virtual Reality Art: Genesis Ultimate Re-creation", VR art has the following 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 manifestation 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 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 art, its biggest advantage lies in the construction of works and participants in the dialogue, through the dialogue to reveal the meaning of the process of generating.

　　Artists through the VR, AR and other technology applications, you can use a more natural means of human-computer interaction to control the form of works to create a more immersive art environment and reality can not achieve the dream, and to create the process to New meaning. 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 artist can use the software and hardware to promote the smooth cooperation between the participants and the work of communication and feedback, to create a good participation And can be manipulated; can also be captured through the video interface to capture, store the behavior of the visitor fragment to keep the participants in the sense of enhancements based on the synchrotron to enhance the effect and re-shape, processed images; by enhancing the reality, Reality and other forms, the digital world and the real world together, the audience can control the projection through their own text, such as data gloves can provide force feedback, mobile scenes, 360-degree rotation of the sphere space not only enhanced the immersion of the work And can make the audience into the interior of the work, manipulate it, observe its process, and even give the audience the opportunity to participate in 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)存訪問者的行為片段，以保持參與者的意識(shí)增強(qiáng)性為基礎(chǔ)，同步放映增強(qiáng)效果和重新塑造、處理過(guò)的影像;通過(guò)增強(qiáng)現(xiàn)實(shí)、混合現(xiàn)實(shí)等形式，將數(shù)字世界和真實(shí)世界結(jié)合在一起，觀眾可以通過(guò)自身動(dòng)作控制投影的文本，如數(shù)據(jù)手套可以提供力的反饋，可移動(dòng)的場(chǎng)景、360度旋轉(zhuǎn)的球體空間不僅增強(qiáng)了作品的沉浸感，而且可以使觀眾進(jìn)入作品的內(nèi)部，操縱它、觀察它的過(guò)程，甚至賦予觀眾參與再創(chuàng)造的機(jī)會(huì)。”

　　vr關(guān)鍵技術(shù)

　　Virtual reality is a combination of a variety of technologies, including real-time three-dimensional computer graphics 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 graphics

　　By 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, but the key here is real time. For example, in the flight simulation 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.

　　Show

　　When people look around the world, because of the different positions of the two eyes, the image is slightly different, 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 comparison.

　　In the VR system, binocular stereoscopic vision played a significant role. The two images seen by the user's 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 other 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 user sees the scene by the user's 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 user's visual system and motion-aware system are separate, and use the head tracking to change the image The perspective of the user's 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 through 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, 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 data gloves and data clothing.

　　Sound

　　People 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 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 the sound and the user's head has nothing to do with the movement.

　　Feel feedback

　　In 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 impossible. A common device for solving this problem is to install some vibrable contacts on the inner layer of the glove to simulate tactile sensation.

　　Voice

　　In the VR system, the voice input and output is also very important. This requires that the virtual environment be able to understand the human language and interact with people in real time. It is quite difficult for a computer to recognize a person's 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 same 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 two 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 one's 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)，就形成了一個(gè)關(guān)于周圍世界的整體景象，這個(gè)景象中包括了距離遠(yuǎn)近的信息。當(dāng)然，距離信息也可以通過(guò)其他方法獲得，例如眼睛焦距的遠(yuǎn)近、物體大小的比較等。

　　在VR系統(tǒng)中，雙目立體視覺起了很大作用。用戶的兩只眼睛看到的不同圖像是分別產(chǎn)生的，顯示在不同的顯示器上。有的系統(tǒng)采用單個(gè)顯示器，但用戶帶上特殊的眼鏡后，一只眼睛只能看到奇數(shù)幀圖像，另一只眼睛只能看到偶數(shù)幀圖像，奇、偶幀之間的不同也就是視差就產(chǎn)生了立體感。

　　用戶(頭、眼)的跟蹤：在人造環(huán)境中，每個(gè)物體相對(duì)于系統(tǒng)的坐標(biāo)系都有一個(gè)位置與姿態(tài)，而用戶也是如此。用戶看到的景象是由用戶的位置和頭(眼)的方向來(lái)確定的。

　　跟蹤頭部運(yùn)動(dòng)的虛擬現(xiàn)實(shí)頭套：在傳統(tǒng)的計(jì)算機(jī)圖形技術(shù)中，視場(chǎng)的改變是通過(guò)鼠標(biāo)或鍵盤來(lái)實(shí)現(xiàn)的，用戶的視覺系統(tǒng)和運(yùn)動(dòng)感知系統(tǒng)是分離的，而利用頭部跟蹤來(lái)改變圖像的視角，用戶的視覺系統(tǒng)和運(yùn)動(dòng)感知系統(tǒng)之間就可以聯(lián)系起來(lái)，感覺更逼真。另一個(gè)優(yōu)點(diǎn)是，用戶不僅可以通過(guò)雙目立體視覺去認(rèn)識(shí)環(huán)境，而且可以通過(guò)頭部的運(yùn)動(dòng)去觀察環(huán)境。

　　在用戶與計(jì)算機(jī)的交互中，鍵盤和鼠標(biāo)是目前最常用的工具，但對(duì)于三維空間來(lái)說(shuō)，它們都不太適合。在三維空間中因?yàn)橛辛鶄€(gè)自由度，我們很難找出比較直觀的辦法把鼠標(biāo)的平面運(yùn)動(dòng)映射成三維空間的任意運(yùn)動(dòng)?，F(xiàn)在，已經(jīng)有一些設(shè)備可以提供六個(gè)自由度，如3Space數(shù)字化儀和SpaceBall空間球等。另外一些性能比較優(yōu)異的設(shè)備是數(shù)據(jù)手套和數(shù)據(jù)衣。

　　聲音

　　人能夠很好地判定聲源的方向。在水平方向上，我們靠聲音的相位差及強(qiáng)度的差別來(lái)確定聲音的方向，因?yàn)槁曇舻竭_(dá)兩只耳朵的時(shí)間或距離有所不同。常見的立體聲效果就是靠左右耳聽到在不同位置錄制的不同聲音來(lái)實(shí)現(xiàn)的，所以會(huì)有一種方向感?，F(xiàn)實(shí)生活里，當(dāng)頭部轉(zhuǎn)動(dòng)時(shí)，聽到的聲音的方向就會(huì)改變。但目前在VR系統(tǒng)中，聲音的方向與用戶頭部的運(yùn)動(dòng)無(wú)關(guān)。

　　感覺反饋

　　在一個(gè)VR系統(tǒng)中，用戶可以看到一個(gè)虛擬的杯子。你可以設(shè)法去抓住它，但是你的手沒有真正接觸杯子的感覺，并有可能穿過(guò)虛擬杯子的“表面”，而這在現(xiàn)實(shí)生活中是不可能的。解決這一問題的常用裝置是在手套內(nèi)層安裝一些可以振動(dòng)的觸點(diǎn)來(lái)模擬觸覺。

　　語(yǔ)音

　　在VR系統(tǒng)中，語(yǔ)音的輸入輸出也很重要。這就要求虛擬環(huán)境能聽懂人的語(yǔ)言，并能與人實(shí)時(shí)交互。而讓計(jì)算機(jī)識(shí)別人的語(yǔ)音是相當(dāng)困難的，因?yàn)檎Z(yǔ)音信號(hào)和自然語(yǔ)言信號(hào)有其“多邊性”和復(fù)雜性。例如，連續(xù)語(yǔ)音中詞與詞之間沒有明顯的停頓，同一詞、同一字的發(fā)音受前后詞、字的影響，不僅不同人說(shuō)同一詞會(huì)有所不同，就是同一人發(fā)音也會(huì)受到心理、生理和環(huán)境的影響而有所不同。

　　使用人的自然語(yǔ)言作為計(jì)算機(jī)輸入目前有兩個(gè)問題，首先是效率問題，為便于計(jì)算機(jī)理解，輸入的語(yǔ)音可能會(huì)相當(dāng)啰嗦。其次是正確性問題，計(jì)算機(jī)理解語(yǔ)音的方法是對(duì)比匹配，而沒有人的智能。
