멀티미디어 디자인에서 정보시각화 방안에 관한 연구

Abstract

The early information expression was made by visualizing information with simple diagrams such as form, color and letter, but such an information expression in the age of digital has been varied and ability to communicate information has been developed not to be compared to the past one owing to rapid increase of information use. In particular, how to express information has been complicated with technical development of multimedia and it has been faced with difficulties in utilizing limited space due to limitation of canvas to express information compared to the amount of information. Various information visualization techniques to solve these problems have been proposed. Information visualization methods are to cope with rapidly increasing information and to make users understand complex and more information more easily. Information visualization in multimedia design is a visualization method to make users understand a large amount of information more easily and shows information necessary for users in limited screen space visually. In addition, it can refer to situation of a large capacity according to the stream of time, visualize a lot of hierarchy structures more easily and retrieve detailed information effectively. This study is to discover features and problems of visualization through analysis of information visualization cases in order to present how to retrieve a large amount of information effectively in information visualization of multimedia design area, arrange visualization embodiment factors through cases and propose effective methods for web bookmark visualization based on it. First, it analyzes features and problems of each visualization through visualization cases by information structure types in multimedia design like linear structure, hierarchy structure, network structure and vector scatter structure and then systematizes expression methods of information visualization based on these. Second, it arranges embodiment factors including binding, layout, clustering, overview, details-on-demand and filtering for visualization based on case studies of information visualization and provides basic data necessary for building information visualization in multimedia design. Third, it examines bookmark demands by users, applies characteristics and embodiment factors of information visualization obtained from case studies to this case and presents and embodies effective guideline of web bookmark visualization. Fourth, it conducts and verifies use convenience evaluation of web bookmark information retrieval visualization suggested. This paper suggests web bookmark visualization as a part of information visualization methods in multimedia design. Visualization of this research is presented with limited simulation embodiment, but it is considered that it will be very helpful in designing more effective web bookmark based on guideline of web bookmark visualization and in developing a new visualization interface development through feature analysis and expression methods of information visualization suggested in this research. Further expression of information visualization will be applied to all areas related to interface as well as information visualization in multimedia design with utilization of multi-dimensional space, combination with virtual reality and a new visualization method and be able to get more information efficiently.
