Virtual Art From Illusion to Immersion phần 6 ppsx

work, dislocating the central position of the author, and enhancing the work through harnessing the imagination of the participating spectators. The development of cybernetic control processes since the mid– twentieth century was the innovation that provided the basis for inter- action with computers and made possible works that the author did not define exclusively any longer. Like her predecessors Popper, Davis, Good- man, and Sakane,34 the art historian So ¨ ke Dinkla locates the origins of the idea of interaction in the classic period of the avant-garde, specifically Futurism and Dada, with Marinetti’s Variety Theatre Manifest and Max Ernst’s exhortations to participate of the 1920s. Further lines of this de- velopment continue in happenings, cyborgart, 1960s reactive environ- ments, and closed circuit technology.35 Any concept of a work that seeks to give an idea an existential form for adefinite period of time in space diverges categorically from the onto- logical appearance of a work of virtual reality. These ephemeral image spaces, which change within fractions of a second, achieve the effect of existing only through a series of computations in real time, 15 to 30 per second. The image is constituted as a spatial effect, via the interposing program and HMD, only on reaching the cerebral cortex;36 thus it leaves its medium in a twofold sense. Recently developed laser scanners can project virtual reality images directly onto the retina; in this case, the category ‘‘image’’ does not disappear altogether—if the retina will suffice as a medium—but this must surely constitute the most private form of image currently imaginable: an image that is seen only by the observer, who triggers or retrieves it through actions or movements. Moreover, these virtual images will be seen only once by one person before they disappear forever—something that is entirely new in the history of the image. There are certain parallels with the cathode ray tube, still an essential component in the majority of existing television and monitor screens, for there, also, a complete picture never exists. A ray of light scans the lines, causing luminescent bodies to emit light for a fraction of a second. It is the sluggishness of the human eye, the so-called retinal afterimage (inves- tigated by Goethe in his Farbenlehre)37 that produces the effect of a com- plete picture on the screen. In this serial image production, which is invisible to the naked eye, images continually appear and disappear for good in fractions of seconds. To construct a work using photons is de facto the immaterialization of the work, although the equipment used to create Chapter 5 206 it is far from immaterial. It is this immateriality that represents the pre- requisite for the highest degree of variability possible and the basis for interaction. Materiality—if one wishes to call it that—is limited to the individual pixel. The ontological character of a work of art as defined by Heidegger38 and others no longer obtains in the aesthetics of computer- aided virtual reality. For this reason, such works are defined increasingly in terms of their processual nature, which stresses their unfinished or open quality and locates art within a framework of communicative social relations. Material works of all epochs have served as points where memories and recollections are crystallized, whether gravestones, medals, paintings, or other artifacts—even film. Memories change over time and according to the given state of knowledge, society or social class, whether dominant or dominated. The strength of material works of art, both past and present, lies principally in their function as illuminating and vibrant testimonies of the social memory of humankind. For only fixed artworks are able to pre- serve ideas and concepts enduringly and conserve the statements of indi- viduals or an epoch. An open work, which is dependent on interaction with a contemporary audience, or its advanced variant that follows game theory—the work is postulated as a game and the observers, according to the ‘‘degrees of freedom,’’ as players—effectively means that images lose their capability to be historical memory and testimony. In its stead, there is a durable technical system as framework and transient, arbitrary, non- reproducible, and infinitely manipulable images. The work of art as a dis- crete object disappears. Computers may be the best repository of all time for information—as long as the operating system or storage medium is not out of date—but they are unable to record or reproduce the sensual pres- ence of a material work of art. Unlike the qualities of material works of art, games and arbitrary interaction do not qualify the computer as a medium for memories and recollections.

Osmose uses the following hardware configuration: SGI Onyx Infinite Reality Engine2 with R4400 150 Mhz Prozessor, 2 RM6’s, plus 128 MB RAM, DAT drive, 2GB Hard Disk, CD-ROM drive. A Macintosh computer, receiving com- mands from an SGI computer, controls various MIDI applications, sound synthe- sizers, and processors. Image and sound, as well as position sensors, are contained in an HMD with a Polhemus tracker and a motion-tracking vest. There is also a data-beamer and a digital stereo amp with speakers. 4.

The Natural Interface 211 9 6 Spaces of Knowledge Knowbotic Research (KR+cF): Dialogue with the Knowbotic South Since their formation in 1991, the Austro-German artist group Knowbotic Research (Yvonne Wilhelm,1 Christian Hu¨ bler,2 and Alexander Tucha- cek3) have developed hybrid models for digital representations of knowl- edge. Knowbotic Research have received many awards for their work,4 and in 1998, all members of the group were given a professorship at the Uni- versity for Art and Design in Zurich. Their virtual installation Dialogue with the Knowbotic South (DWTKS) (1994–1997), which has been exhib- ited at several exhibitions,5 processes scientific data from research stations’ networked data bases to create a changing abstract representation of An- tarctica. It visualizes and maps this deserted, yet scientifically well- documented, continent in a virtual scenario, but does so in a totally nonmimetic way.6 In DWTKS, the data from the networks is visualized as changing starbursts of pixels on large projection screens in a dark room. The data is collected and activated by software agents, the knowledge robots or ‘‘knowbots.’’ The image space consists of complex dynamic fields where exchange and interaction take place between the human visitors and the knowbots and poetic software machines. The data, arranged in the virtual space like constellations of stars, are pulled together, as if attracted by a magnet, and then burst apart again, like supernovas. The installation also presents the physical topology of several research and monitoring sta- tions in the Antarctic on a plastic film on the floor. The artificial space can be experienced both virtually and abstractly; the user navigates by moving a touchwand, an interface reminiscent of the joystick. Wearing a headset with a mini-monitor, the ‘‘private eye,’’ in front of one eye, the visitor explores the glowing, rotating data fields and correlated metallic sounds, which produces an extraordinary feeling of space. Currents of conditioned cold air, the temperature of which derives from data recorded by meteoro- logical stations on the sixth continent, is blown into the installation space. It is a polysensory environment that the visitor encounters in DWTKS. This combination of physical and virtual components that represent the multiple layers of the real was created years before hybrid artworks of this kind appeared in the discussion as ‘‘mixed realities.’’ It took two years to develop DWTKS; the group received some sup- port from the hardware producers who lent their machines, and invested 50,000 U.S. dollars of their own money in the project. For young gradu- ates, this was a considerable sum and also the limit of what they could Spaces of Knowledge 213 raise. Although Knowbotic Research were expert in the most important programs, such as C + and Java, for DWTKS they also had to rely on the help of professional programmers for exceptional software solutions. When artists employ professionals, who work for much less than they would get in the commercial sector, they have to mobilize considerable skills of per- suasion for art’s sake. In the hypothetical space of DWTKS, the knowbots are the units that structure, visualize, and establish contact with the artificial space. The users enter into contact with these virtual software agents and use them to access the data live from the electronic networks of the Antarctic research stations. Theoretically, this happens in real time; practically, the data is updated every three hours. The knowbots condense the information dy- namically and allow the users to access it. Using a wand—an interface that is neither ‘‘intuitive’’ or ‘‘natural’’—the users can log in via knowbot to the swirling data fields and intervene. The knowbots function as non- representational interfaces between programs and active users; they are visualized, abstract representations of knowledge that is undergoing per- manent change. However, communication with these early forms of agents is confined to moving through the data fields and activating correlated sounds. The knowbots appear to the user in the form of local swirls of data, and, when activated, they visualize keywords of the given collabo- rating research project (for example, diving robots), and the user can also activate with his or her gaze accompanying fragments of sounds. In the image space, these are combined faster by a knowbot the closer the user’s gaze is to the agent. When Alexander von Humboldt returned from his field trip to South America, he proposed the construction of a panoramic space of images depicting a highly complex and foreign reality for visitors. This is not the aim of Knowbotic Research: They invite the user to explore and inter- rogate interactively an abstract, self-organizing system. The visitor is not offered immersion in an illusionistic artificial Antarctic landscape but a plunge into an image space filled with abstract scientific data, a space of constant metamorphosis: This is the intention of the artists. Following Giambattista Vico, who asserted that we can only under- stand what we have created ourselves, DWTKS enables scientific data, that is, columns of figures, from Antarctic research stations to be translated into three-dimensional audiovisual representations and temperature-controlled Chapter 6 214 air streams. This multiperspectival perception, which is communicated on various levels, including the mini-monitor and panoramic view on large projection screens (fig. 6.1), raises questions about traditional mimetic concepts of computer art. Although Knowbotic Research operate within the context of the virtual reality discourse, also working with the total effect produced by sounds and images, they choose to represent complex, chaotic, and abstract systems in a form diametrically opposed to that of the mimetic approach. DWTKS allows the user to witness actively how science models and simulates Antarctica, a continent not fully explored, with ex- treme natural and climatic conditions and scant history of civilization: computer-aided nature.7 Their visualization of scientific data does not cre- ate an artificial space of illusion but, instead, an abstract dynamic knowl- edge space that is capable of representing changes over time, for example, the constant movements of icebergs. The artists’ computer-aided approach, however, does not conform to the view of some scientists that the com- puter can construct and represent anything and everything.
