目的 探究数字化单兵作战终端态势感知与人机交互设计方法及应用。方法 通过项目实践，分析现有单兵作战信息化装备使用方式与使用效率，提出单兵作战态势信息可视化的设计原则与设计方法，提高信息终端人机交互使用效能，增强作战情境意识和支持作战任务管理，达到简化作战信息复杂程度，契合作战用户群体需求的任务。在此基础上，展开某型号单兵作战平板的交互式人机界面设计实践，并进行可用性测试验证设计方案的可行性。结论 数字化单兵信息显示终端是基于视觉认知理论，对信息显示系统中的人机要素、布局要素、交互要素及视觉显示要素开展整体分析与设计，从视觉认知规律出发，践行以目标为导向的设计流程，在单兵作战态势平板上显示的多模态信息作出明确的层级区分，减轻复杂信息造成的记忆负担，显著提升作战信息传递和任务执行的效率，可以有效提升系统的可用性、易用性和操作满意度。

This paper aims to explore the design method and principals for interactive individual combat information visualization system. The operation and efficiency of existing individual combat information system are analyzed, an improved one which provides combat mission management, differentiated display according to the importance of information is proposed, users' awareness of combat situations is enhanced, their memory burden is reduced, and they are allowed to interact with terminals more efficiently to better meet their needs. This system is based on visual cognitive theory, and is designed from the perspectives of human-machine interaction, layout, and vision. The useability of the proposed system is verified by experiments. The results reveal that the proposed system significantly improves the efficiency of information transmission, and allows users to perform their mission more effectively, thus improving users' satisfaction.
