PDA를 기반으로 한 GPS의 유저 인터페이스 개발에 관한 연구

User Interface is often designed and manufactured from a perspective of a developer because of the system's limited functions and extent despite the fact that it should be manufactured in a way that it can promote efficient communication from a user's perspective. To solve this problem, the developer and the interface designer should cooperate at the very initial stage of the system development and onwards, engendering the concurrent development of the functional system structure design desired by a user and of the components design necessary for communication with a computer. In particular, the functional structure design should take on the direction in which it can turn the functions a user may demand in the system into images and a user can easily understand and interpret the information that is displayed on the screen as the product of the system operation. In this study, the theories of UI were first analyzed, and the user's demands were turned into images based on the fundamental structure and functions specification of the GPS system. Then the navigation, the dialogue button and box, images, and displays were organized to produce an integrated screen layout, which was suggested.
