The work aims to explore the impact of traditional cultural WeChat mini program interface design elements on users' learning interests. By analyzing interface design factors, it aims to reveal how interface design elements promote users' interest in learning traditional culture. The mini program interface scheme independently designed by the author was used as a research sample and combined with subjective questionnaires and eye tracking experiments, the impact of different interface design elements on users' learning interest during use was studied. Eye tracking data and questionnaire survey results both showed that in the interface design of traditional cultural WeChat mini programs, appropriate font styles and color combinations, engaging interactive design, and reasonable functional layout played a significant role in enhancing users' interest in learning. The findings of this study provide theoretical basis and practical guidance for improving users' experience and learning interest for the interface design of traditional cultural WeChat mini programs. These conclusions have important reference value for designers on how to stimulate and maintain users' learning interest through interface design when developing similar applications.
