GUI 디자인의 구성요소가 사용자 만족에 미치는 영향 - 차량용 네비게이션 제품을 중심으로 -

Abstract

The purpose of this study is to analyze the relevance between components of GUI design for a vehicle navigation and user's satisfaction. In order to achieve this goal, layout, text, graphics and multimedia were assigned as the independent variables and user's visibility and understanding were assigned as dependent variables. The regression analysis was performed with those variables. The results are as follows. First, according to analysis on the relevance between components of GUI design of a vehicle navigation and 'user's visibility', it was found that layout, text, graphics and multimedia factors affected user's visibility. In addition, the most relative influence of components of GUI design on user's visibility was text. Graphics, layout and multimedia were followed in order. It was found that text and graphic factors affected components of GUI design relatively more than other factors. These results suggest that 'text' factor and 'graphic' factor should be considered with priority than other factors in order to increase user's visibility. Second, according to analysis on relevance between components of GUI design of a vehicle navigation and 'user's understanding', it was found that graphics, text, layout, and multimedia factors affected user's understanding. In addition, the most relative influence of components of GUI design on user's understanding was graphics. Text, layout and multimedia were followed in order. It was found that graphic and text factors affected components of GUI design relatively more than other factors. These results suggest that 'graphic' factor and 'text' factor should be considered with priority than other factors in order to increase user's understanding. The significance of this study is to identify the influential factors which can increase the user's visibility and understanding with consideration of approach factors of GUI design, and approach to the product design satisfying the characteristics of users. In addition, it is considered as the attempt to explore the components of GUI design which may affect user's implications and understanding by the integrated approach considering multiple factors at the same time rather than individual component of GUI design. Finally, the limitation of this study is the sample size. It is difficult to generalize these results by applying them to all navigation products due to a small number of samples. Thus, it is thought that the sample size should be increased and this study should be expanded to kinds of products to examine user's satisfaction factors in the future.
