| 目的 扫一扫(Scan QR Code)既是许多手机应用软件采用的功能界面，又是其他更多拓展功能的入口。研究影响扫一扫界面可用性设计的因素，可为扫一扫的界面设计提供理论支持与设计指引。方法 归纳分析现有扫一扫界面，将其界面组成划分为扫描框、模式切换图标、功能辅助图标三类组件。以组件布局关系、图标背景隔离作为研究自变量，设计不同自变量水平下的被试者内图标搜索实验，以眼动追踪记录搜索过程中的数据。通过重复测量方差分析反应时间、注视点个数、眼跳次数三种眼动数据，比较研究自变量对扫一扫界面可用性的影响。结果 实验数据表明，组件布局关系在这三种数据上都存在显著性差异，且邻近的组件布局关系的眼动数据优于远离型。图标背景隔离在反应时间、注视点个数上存在显著差异，且图标背景隔离的眼动数据优于图标背景不隔离的。结论 邻近型组件布局关系与图标背景隔离都对扫一扫界面可用性具有正向影响。 |

| Scan is not only the common functional interface of many mobile applications, but also the entrance of more expanded functions. The work aims to study the factors affecting the usability of scan interface and provide theoretical support and design guidance for design of scan interface. The existing scan interfaces were summarized and analyzed. The interface composition was summarized into three kinds of component:scan box, mode switching icon, and functional auxiliary icon. With layout relation between components and isolation of icons and background as independent variables, an icon search experiment under different levels of independent variables was designed, and the data in the search process were recorded by eye tracking. The effects of independent variables on the usability of scanning interface were studied by comparing three kinds of eye movement data, namely response time, number of fixation points and saccadic times, through repeated measurement of ANOVA. The experimental data showed that there were significant differences among the three kinds of data in terms of component layout relation, and the eye movement data of the adjacent component layout relation was superior to that of the distance type. There were significant differences in response time and number of fixation points in isolated icons and background, and the eye movement data of icon background isolation is superior to that of non-isolated icons and background. Adjacent component layout and isolated icons and background have a positive impact on the usability of the scan interface. |
