EVALUATING USER INTERFACE REQUIREMENTS FOR BEIDOU-BASED CONSUMER MAP NAVIGATION APPLICATIONS IN CHINA

Abstract

BeiDou-based consumer map navigation applications are increasingly important for daily mobility in China, supporting route planning, real-time location services, and travel decision-making in both urban and rural environments. Although existing studies have widely examined the technical performance, positioning accuracy, and service development of the BeiDou Navigation Satellite System (BDS), comparatively less attention has been given to the user interface requirements that shape user experience, usability, trust, and adoption. To address this gap, this paper presents a conceptual framework for evaluating user interface requirements in BeiDou-based consumer map navigation applications. The study organizes UI requirements into four major categories: functional, visual, interaction, and adaptive requirements. These categories cover essential interface elements such as destination search, route guidance, map clarity, icon visibility, menu organization, alert notifications, personalization, and context-aware adaptation. The proposed framework integrates requirement identification, user-centered assessment, expert feedback, statistical analysis, and multi-criteria prioritization methods, including AHP, ANP, and Fuzzy ANP. It also introduces simulation-based and graphical representations to demonstrate how interface requirements can be analyzed, ranked, and refined in future empirical studies. By linking BeiDou-enabled navigation services with human-computer interaction and mobile usability principles, this study provides a structured foundation for improving navigation interface design. The framework can support researchers, designers, and developers in identifying critical UI elements and producing more usable, efficient, and context-aware navigation applications. Future work will involve empirical validation through user surveys, expert evaluation, and requirement prioritization to generate practical design guidelines for diverse consumer users in China.
