تاثیر عناصر بصری دیوارنگاره‌های ایستگاه متروی تئاتر شهر تهران بر مطلوبیت ادراکی- بصری از منظر شهروندان، متخصصان و هنرمندان

از آنجا که ایستگاه‌های مترو در زمره فضاهای همگانی شهرها قرار می‌گیرند، جداره آنها مشتمل بر آثار هنری همگانی به ویژه دیوارنگاره‌ها، بخشی از منظر شهری به حساب می‌آید. آثار هنری موجود در جداره می‌تواند با ایجاد سامانه ارتباطی میان اثر، هنرمند و مخاطب، زمینه‌ای برای تعامل بیشتر میان مردم و محیط فراهم آورد. بدین‌جهت، شناخت عوامل موثر بر ترجیحات بصری مخاطبان برای ایجاد مطلوبیت ادراکی _ بصری ضرورت دارد. هدف این پژوهش، شناخت چگونگی تاثیر عناصر بصری دیوارنگاره‌های ایستگاه متروی تئاتر شهر بر مطلوبیت ادراکی _ بصری با تاکید بر بعد بصری جداره ایستگاه است. این پژوهش به‌دنبال پاسخ به این پرسش است که عناصر بصری دیوارنگاره‌های ایستگاه متروی تئاتر شهر چگونه بر مقبولیت و مطلوبیت بصری جداره ایستگاه تاثیرگذارند؟ برای پاسخ به این پرسش، از روش آمیخته و برای گردآوری داده‌ها از روش‌های مشاهده، مصاحبه و تکنیک ترجیح بصری استفاده شده است. از بین شهرهای گوناگون، به لحاظ موقعیت الگوفرستی، شهر تهران و از میان ایستگاه‌های مترو در این شهر، ایستگاه متروی تئاتر شهر به دلیل موقعیت مکانی و نزدیکی به خیابان ولی‌عصر، تئاتر شهر و پارک دانشجو انتخاب شد. از میان دیوارنگاره‌های این ایستگاه، نُه دیوارنگاره‌ مورد آزمون قرار گرفت. نتایج حاکی از آن است که مطلوبیت ادراکی _ بصری در هر سه گروه ناظران تعلیم‌نیافته (شهروندان)، ناظران تعلیم‌یافته (متخصصان هنرهای تجسمی) و خالقان آثار (هنرمندان) وجود داشته و نظر شهروندان و هنرمندان به یکدیگر نزدیک‌تر بوده است. در ارزیابی به‌عمل آمده، شهروندان از به‌کارگیری طرح‌های دارای نوآوری، ریتم و تضادهای فرمی استقبال نموده و از نظر ایشان محل نصب دیوارنگاره‌ها به لحاظ میدان و زاویه دید و ارتباط با جداره‌ها مطلوب ولی نورپردازی آثار، نامطلوب ارزیابی شد. این موارد در نمونه‌های مورد مطالعه به عنوان عوامل اصلی مطلوبیت ادراکی _ بصری با تاکید بر بعد بصری دیوارنگاره‌های ایستگاه شناخته شد.

The effect of the visual elements of the murals of Tehran Theater Metro Station on the perceptual-visual desirability from the viewpoint of citizens, professionals and artists

Highlights:Artworks concerning frontages as media of communication among the artwork, the artist, and the public and frameworks for interaction with locationsCommon viewpoint held by untrained observers (citizens), trained observers (visual art specialists), and creators (artists) in the appraisal of the perceptualvisual desirability of muralsCloseness of the citizens’ and artists’ attitudes toward the appraisal of the perceptualvisual desirability of muralsCitizens’ greater appreciation of the use of creative designs with rhythms and formal contrasts in the appraisal of the perceptualvisual desirability of murals IntroductionAs subway stations are regarded as public spaces in cities, their frontages, involving public artworks, especially murals, are taken into account as part of the urban townscape. The artworks on frontages can provide a medium for interaction, functioning as a visual communication system among the artwork, the artist, and the public. Therefore, it is important to identifying the factors influencing the visual preferences of the audience. The aim of this paper is to investigate the effect of the visual elements of murals on the perceptualvisual desirability of frontages at the Tehran Theater subway station. It seeks to answer the question of how the visual elements of the murals at the station affect the perceptualvisual desirability of the station frontage.Theoretical FrameworkAmong the large number of visual components assumed by various theorists, the main common components taken into account is this research include color, shape, texture, line, tonality, and light  (Jansen, 1998: 69). This study investigates element quality, the quality of the relationship between elements, and that for figures and the ground (Pakzad, 2006) to achieve the degree of visual desirability in response to questions about the aesthetic component and the scape quality. The element quality is mural, and the relationship between the murals is considered for appraisal of the quality of the relationship between the elements. Moreover, the relationship between the mural and the wall is considered for appraisal of the quality of the relationship between the figure and the ground. The components related to the quality of the element include intensity, tension, and ingravibility, those pertaining to the quality of the relationship between the elements include balance, symmetry, proportion, dominance, clarity, and density. The components concerning the quality of the relationship between a particular element and others (figure and ground) include contrast, opposition, conformity, advantage, hindrance, emphasis, enclosure, narrowness, openness, sequence, and concentration (ibid.: 121136)MethodologyFor achievement of the research aim, a mixed method was adopted based on data collection through archives, observations, interviews, and visual preference techniques. Among different cities, Tehran was selected due to its position, and the Tehran Theater subway station was chosen among different stations because of its location in the proximity of Valiasr Street, Tehran Theater, and Daneshju Park. Then, nine murals were selected from among those available at the station. Given the nature of the data, the methods of regression analysis and correlation analysis were used along with SPSS techniques for analysis of the collected data.Result and DiscussionThe results indicated that perceptualvisual desirability existed in all the three groups: untrained observers (citizens), trained supervisors (visual art experts) and creators of artworks (artists). The findings also demonstrated that tonality (degree of darkness/brightness), shape (design), color, line, and texture exhibited the greatest impacts on perceptualvisual desirability, in that order. The elements of shape, color, tonality, line, and texture played the greatest roles, in order of priority, in the perceptualvisual utility of the station frontage for the citizens, the elements of tonality, shape, line, texture, and color for the specialists, and shape and tonality, color, and line and texture for the artists. The most important reasons for these differences follow. The main reason why tonality was selected as the first priority by the three information sources is the community’s need to observe color diversity at different levels of the society. Unfortunately, this field has been neglected for years. However, its negative effects, such as the increase in the number of patients with depression, are evident. The second priority involved the designs and patterns used in the murals, which demonstrated the significance of form and content and of the choice of subject and consideration of the aspects of visual beauty. In the studied cases, the messages and feelings that the artist tried to convey to the audience had a negative impact on citizens’ perception although understood to a large extent by the audience, as the predicted lighting was not considered properly, the mural lights were used only occasionally, and inappropriate accessions led to visual disturbance. ConclusionThe results indicated perceptualvisual desirability in all the three groups of untrained observers (citizens), trained observers (visual art specialists), and creators (artists). Furthermore, the citizens’ and artists’ opinions were close to each other. The citizens appreciated the use of creative designs with rhythms and formal contrasts, being satisfied both with the location of the murals in terms of visibility and viewshed and with their association with the frontages, but not with the lighting of the works. These were identified as the main perceptualvisual desirability factors in the studied samples.
