目的 探讨移动应用界面中视觉设计干扰子对搜索效率的影响机制，为提高视觉界面搜索效率提供搜索界面设计策略和方法。方法 通过文献研究，梳理视觉搜索理论及行为模型，并在此基础上探究视觉信息搜索思维逻辑。并基于某大学图书馆研修室预约系统，设计制作7组界面视觉干扰子实验样本，通过动态界面交互眼动实验研究，探明界面视觉设计干扰子对搜索效率的影响机制。结果 在界面结构、功能布局、交互方式、信息表现、信息层级、色彩搭配与UI动效7组不同界面视觉设计干扰子样本中，用户目标任务的搜索效率都有显著差异。结论 搜索类型界面设计应使界面结构清晰，主次功能分布合理，尝试灵活多样的交互方式，尽量减少信息层级以及进行适当的信息可视化，给用户舒适的色彩对比度以及恰当的UI动效引导。

Influence Mechanism of Interface Visual Design Distractors on Search Efficiency

The work aims to explore the influence mechanism of visual design distractors on search efficiency in mobile application interface, and propose design strategies and methods to improve the search efficiency of visual interface. Literature research, visual search theories and behavioral models were sorted out. And on this basis, visual information search thinking logic was explored. Based on the study room reservation system of a university library, 7 sets of experimental samples of interface visual distractors were designed. Through dynamic interface interaction experimental research on eye movement, the mechanism of influence of interface visual design distractors on search efficiency was ascertained. Among the 7 sets of different interface visual design distractors in interface structure, functional layout, interaction mode, information presentation, information hierarchy, color matching and UI animation guide, the search efficiency of user target tasks was significantly different. Search type interface design should make the interface structure clear and the distribution of primary and secondary functions reasonable. It is required to be more flexible in interaction, minimize information hierarchy and visualize information appropriately, and give users comfortable color contrast and appropriate UI motion guidance.
