中文摘要:

      目的 改善村寨导视系统的用户体验，探寻用户评价导视系统满意度的标准体系，提供客观、以用户为导向的设计流程。方法 使用文本挖掘技术对用户评价原始数据进行采集，使用探索性因子分析法对结果进行降维分析，通过主成分分析法提取5个成分，将其设置为潜在变量，并将相关指标作为观测变量，再使用结构方程模型构建潜在变量与观测变量之间的层次结构，并对其结果进行拟合度分析，最后将结果用于导视系统设计实践。结果 根据结构模型结果，分析潜在变量和观测变量的影响权重，得出并验证了“明确的指向性”是影响用户满意度最重要的指标，其次分别为“民族造型美感”“文化功能性”“场景交互合理”，并通过具体的观测变量因子载荷数值排序来指导设计实践。结论 导视系统在实现指向性功能的情况下，还应提升民族文化附加值，通过文化符号来扩大民族影响力，传承民族文化，促进民族村寨的发展。

英文摘要:

      The work aims toimprove the user experience of village guide systems, explore the system standards for user satisfaction evaluations, and provide a design process based on objectivity and user orientation. The text mining techniques were used to collect raw data from user reviews, perform exploratory factor analysis to reduce dimensionality, extract 5 components as latent variables through principal component analysis, and treat relevant indicators as observed variables. Next, the Structural Equation Modeling (SEM) was applied to construct a hierarchical structure between latent and observed variables, followed by a goodness-of-fit analysis of the results. Finally, the findings were used to guide the design practice of the guide system. Through the analysis of the structural model results, the influence weights of latent variables and observed variables were examined, confirming that "clear directional guidance" is the most critical indicator affecting user satisfaction, followed by "ethnic aesthetic appeal", "cultural functionality", and "reasonable scene interaction". Specific observed variable factor loadings were used to guide the design practice. In addition to fulfilling directional functionality, guide systems should enhance the added value of ethnic culture, expand ethnic influence through ethnic cultural symbols, and preserve ethnic culture while promoting the development of ethnic villages.
