为解决数字图形界面态势感知（S A ）难以被客观评测的问题，根据界面作业所需完成的操作任务，提出新的实验流程和范式，采用行为实验和脑电实验相结合的新技术路线，以脑电反馈负波、反应时和正确率三个评价指标分别来衡量SA的“感知性、理解性和可判断性”，为SA的客观评价方法研究提供了新思路和新方法。以战机界面为例，通过22名被试者对空空对战任务进行实例验证。结果表明：通过分析脑电反馈负波呈现实验的客观数据，可实现对SA感知性的评价；通过对界面任务反应时和正确率的对比分析，能实现对SA可理解性和可判断性的评测，从而实现对数字图形界面SA的客观综合评价。

To evaluate Situational Awareness (SA) objectively ,a novel experimental procedure and paradigm were proposed according to the required operation tasks to be finished while the new technology route combining behavior experiment with Event Related Potential (ERP) experiment was used . Three evaluating indicators of feedback negativity ,reaction time and accuracy were used to reflecte the perceptual ,understanding and judgment of SA of digital Graphical User Inter-faces (GUI) ,which provided a new thinking and new method for the quantitative evaluation of SA .Finally ,an application example of the objective evaluation to fighter UI by 22 subjects was giv-en to validate the feasibility and effectiveness of the method .Experiment results show that the electrical feedback negative wave presents the experimental results of objective data which can be used to compare the subjective perceptual quality of users on different interface ,and the contrastive analysis of reaction time and accuracy can reflect understanding and judgment of UI to evaluate the SA of UI .
