Abstract：
This article, from the perspective of structural features, focuses on in-car user interface icons and explores the impact of different icon structural features on visual search efficiency. Initially, we categorised the icons into four groups based on structural features: individual structure icons (ISI), enclosed structure icons (ESI), horizontal structure icons (HSI) and vertical structure icons (VSI). Subsequently, we conducted a visual search experiment with structure as the sole variable, recording participants\' behaviours and eye-tracking data. Finally, data analysis was conducted using methods including analysis of variance and logistic regression. The results indicate that differences in icon structural features significantly affect visual search efficiency, showcasing significant intergroup differences. HSI exhibit the highest visual search efficiency, while ESI show the lowest efficiency. ISI have shorter response times but the lowest matching accuracy. VSI only perform better than ESI. These findings hold significant implications for optimising icon design and enhancing visual search efficiency.
Visual search efficiency of icons is crucial for human-computer interaction. We investigated how the structural features of icons influence visual search efficiency. Horizontal icons are most effective, enclosed icons the least. Individual icons are quick but less accurate. Vertical icons outperform enclosed ones. Structural features should be considered in design.

摘要：
这篇文章,从结构特征的角度来看，重点介绍车载用户界面图标，探讨不同图标结构特征对视觉搜索效率的影响。最初，我们根据结构特征将图标分为四组：个体结构图标(ISI)，封闭结构图标(ESI)，水平结构图标(HSI)和垂直结构图标(VSI)。随后，我们以结构为唯一变量进行了视觉搜索实验，记录参与者的行为和眼动追踪数据。最后,数据分析采用方差分析和逻辑回归分析.结果表明，图标结构特征的差异显著影响视觉搜索效率，显示显著的组间差异。恒生指数表现出最高的视觉搜索效率，而ESI显示效率最低。ISI的响应时间较短，但匹配精度最低。VSI的性能仅优于ESI。这些发现对优化图标设计和提高视觉搜索效率具有重要意义。
图标的视觉搜索效率对于人机交互至关重要。我们研究了图标的结构特征如何影响视觉搜索效率。水平图标是最有效的，封闭的图标最少。单个图标是快速的，但不太准确。垂直图标优于封闭的图标。在设计中应考虑结构特征。
