Sanat sergileri için diyagram tabanlı ve kullanıcı etkileşimli görselleştirme arayüzü tasarımı

In today's conditions, with the increasing data production, technology has undertaken a significant role in refining and transforming data to information and later in the transmission of data to users. Various data visualisation techniques have being developed in various fields such as economy, statistics, medical sciences, architecture and media in such a way that the data shall be transmitted to the user properly and the user can easily produce information out of it. Data visualisation represents a series of processes ranging from obtainig raw data to the consolidation of data in the memory of the user. Since they take the responsibility to educate the various social groups, museums have developed different informal methods and interactive learning models for transforming the data to information. Especially in the museums of history, nature, space and zoology, the data is presented to the visitors after it is reorganized by museum specialists. With this design, data is presented in an interactive way to be explored by the visitor. In this way, visitors may gain an active role throughout the exhibition. On the other hand, visitors in art museums are generally passive observers of an art object that is exposed directly to the visitors' eye with verbal or written informative explanations (information about the theme and label etc.), audio guides and QR codes. For this reason, in order to make the visitors more active during and after the exhibiton, this study has aimed to design a diagram based visualisation and user interface, which arranges the visible and invisible data about the exhibition. The user interface has been designed in a way to create visual representations depending on user's own interests and demands by converting the tangible data (exhibition, works of art, themes, attitude of the museum towards opening exhibitions and cataloguing the data) to abstract diagrams. The interactive interface enables the user to identify the relationship patterns between visual informations and thus aquire new information. The design stages include raw data collection, data transformation, visual structures and images. The user interface has been implemented in the periodic and combined fort he exhibition "Artists in Their Time" hosted by Istanbul Modern Art Museum in 2015 in order to acquire organized data about the exhibition, transfrom and later bring it into the experience of visitors. The raw data of the exhibition were retrieved from the written sources (theme panels, label etc.) of the works in the exhibition area, the catalogues prepared by the museum and the Internet. The main categories of the classification system developed by CDWA (Categories for the Description of Works of Art) was used in the organisation of raw data that is the first step of design process of the visualisation interface. The data collected from 183 different works of art, were separated as textual and numerical data. In addition, certain parts of the textual data were transformed into numerical data in order to prevent data stack and make it easier for the computer to visualize the data. The converted complex data set were represented with 2D visuals to make it easily understandable by the visitors. Some visual structures were built using the basic design elements like points, lines, planes and colours by linking the converted data with each other. In order to create diagrams that describe the visual structures, a coding environment called "Processing" was used for sketching/visualising the link between different kinds of data. Processing environment enables to create visuals by using the organized data by the computer environment. Therefore, we have used it in this study to make it possible for the visitors to use the interface interactively with the help of mouse and keyboard. Within the scope of this study, a three-phase method was developed in order to test the diagram based user interface whether it consists with the design principles decribed in the beginning of the study and serves to the purpose of study. In the first step of experience based inquiries, a survey was conducted to collect the visitors' idea about the exhibition before introducing the user interface and the exhibiton starts. In the second step, the user interface was represented to the visitors. Then, the experiences of visitors while using the interface were observed and the information was recorded through the obtained visual data. In the third step, a second survey was conducted to inquire the similarities and differences between the exhibition and interface observed by the visitors. In conclusion, a user interface was developed by taking the visitor feedbacks into account, which is focused on user interaction, dynamic design and encouraging the information production. Since the CDWA provides universal standards and the selected exhibition offers an extensive combined display of different art works, the designed visualisation interface can also be used for the future art exhibitions. In this way, this study claims to be a flexible and improvable work which can be integrated to various other exhibitions instead of being a fixed and unchangable study which is developed only for a certain application.
