摘　　要：【目的】优化用户体验,提高用户对导航系统的持续使用性。【方法】采用用户实验和基于情感词典的情感分析方法,使用程度副词系数量、中文情感词汇本体、极性短语的强度计算公式等对情感短语进行量化,分析影响情感的因素及其变化规律。【结果】用户在步行导航过程中的情感变化主要受到系统因素和环境因素的影响,系统更新的不及时、定位不准、环境恶劣均会对用户的情感造成影响。【局限】情感是一个复杂而且涵盖广泛的概念,仅通过文本分析可能存在不足。【结论】通过改进系统本身和增添人性化的设置提高用户对导航系统的持续使用性,为系统未来的升级提供有效参考。[Objective] This paper aims to optimize user experience and keep them using the pedestrian navigation system. [Methods] First, we collected data from an experiment with 30 participants. Then we conducted analysis with the help of sentiment dictionaries. Finally, we obtained influencing factors and their changing patterns with the number of degree adverbs, Chinese sentiment vocabulary Ontology and degree-calculating formula of polar phrases. [Results] We found that users＇ sentiment changed due to the systematic and environmental factors. Untimely system updates, inaccurate locations and tough environment all posed negative effects to the user＇s sentiments. [Limitations] Text analysis could not study the sentiments comprehensively. [Conclusions] We could optimize user experience by improving system design and adding user-friendly features, which provides direction for future developments.
