GPS(Global Position System) is the most advanced satellite position system which provide the automatic, continuous, global coverage, all-weather, high precision position, so it has enormous advantage and potential in navigate. With GPS wide application and human-computer interaction technology development, human-computer interface is the important composition of navigation system. The interface design decides user satisfaction and the work efficiency. Firstly, the paper presents the history and actuality of GPS navigation technology, and the composition, position principium, characteristic of GPS; secondly introduce human-computer interaction technology development course, and the concept, design principium, method of graph user interface; Thirdly, presents the interface collectivity design in our system, and the analysis method of facing object; lately presents the realization of the system design and the key technology. The paper include the following kernel work: 1、Analysis and Design of GPS navigation interface system. For user, interface design is more reasonable, simple, visual; and for developer, according to the function analysis, system modeling, prototype handling and combining the function character of navigation system, analyze deeply and design navigation interface with Object Orient principle. 2、Human-computer interface design. Discuss the way of the GPS navigation interface system. and in VC++6.0 realize these function modules: main_interface, line_edit, line_view, navigation_show. 3、Key technology. Introduce the Multithread technique based on MFC; discuss the method of repairing mistake in the human-computer interface; particularly illuminate the arithmetic to actualize the navigation information showing.
