基于 SEM 的交互式公共导识系统体验设计研究

为改善用户对交互式导识系统的满意度并帮助设计人员精准获取用户需求，引入 结构方程模型(SEM)于交互式导识系统中，将交互式公共导识系统的用户体验(UX)要素分成   4个潜变量，然后通过专家访谈的形式分析每个潜变量影响UX满意度的可观测变量并设立SEM 调查问卷，最终通过问卷调查与数据分析，建立交互式公共导识系统用户满意度的 SEM 并得 出 4 个潜变量及其可观测变量的影响权重大小。以校园交互式公共导识系统为例，通过用户满 意度 SEM 对其功能、造型和用户界面进行改良设计来提升 UX，并结合 PSSUQ 与现有交互式 公共导识系统进行比较，以验证设计方案的可行性，为交互式公共导识系统体验设计研究提供 理论参考。

Research on experience design of interactive public guidance system based on SEM

In order to increase user’s satisfaction with the interactive guidance system and help designers to accurately obtain users’ needs, the structural equation model (SEM) is introduced into the interactive guidance system, and the elements of user experience of the interactive public guidance system are divided into four latent variables. Then, through expert interview, the observable variables affecting the user experience (UE) satisfaction of each of the four latent variables are analyzed and the SEM questionnaire is established. Next, through questionnaire survey and data analysis, the SEM of the user satisfaction of the interactive public guidance system is established. And the impact weights of the four latent variables and their observable variables are obtained. Finally, taking the campus interactive public guidance system as an example, the function, shape and user interface are improved to improve the UE based on the above user satisfaction SEM. This method is compared, with the assistance of PSSUQ, with the existing interactive public guidance system to verify the feasibility of the design and then provide theoretical implications for further research on the experience design of the interactive public guidance system.
