基于眼动追踪的指挥控制系统人机交互效能评估方法

Evaluation Method of Human-Computer Interaction Effectiveness of Command and Control System Based on Eye Tracking

指挥控制系统是信息化作战体系的核心支撑,其操作使用的便捷性、准确性等人机交互效能直接影响着作战指挥控制效率。为持续优化指挥控制系统人机交互效能,需要建立科学合理的评估方法。本文引入眼动追踪技术,使用瞳孔直径、眼跳次数、注视点数量等眼动数据,构建指挥控制系统人机交互搜索效率、操作效率、认知负荷、设计复杂性和吸引性等指标的量化评估模型,利用熵权-变异系数法对各眼动数据组合赋权,形成指挥控制系统人机交互效能的综合评估结果。基于该方法对指挥控制系统和指挥信息系统进行对比实验,并利用SUS系统可用性量表和NASA-TLX认知负荷量表的调查结果进行对照分析,结果验证了评估方法的有效性和准确性。

The command and control system is the core support of the information warfare system.The convenience and accuracy of its operation and use directly affect the efficiency of combat command and control.In order to continuously optimize the human-computer interaction effectiveness of the command and control system,it is necessary to establish a scientific and reasonable evaluation method.This paper introduces eye movement tracking technology,uses eye movement data such as pupil diameter,number of saccades,number of fixation points,etc.,to build a quantitative evaluation model of human-computer interaction search efficiency,operation efficiency,cognitive load,design complexity and attractiveness of command and control system,and uses entropy weight-variance coefficient method to weight each eye movement data to form a comprehensive evaluation result of human-computer interaction effectiveness of command and control system.Based on this method,a comparative experiment is carried out on the command and control system and the command information system,and the results of the SUS system availability scale and NASA-TLX cognitive load scale are compared and analyzed.The results verify the effectiveness and accuracy of the evaluation method.
