为预测飞行员视觉注意力分配,在SEEV(Salient Effort Expectancy Value)模型和多因素模型的基础上引入注意控制空间和资源分配空间的概念.前者描述了影响注意力分配因素,而后者则反应了兴趣区域所获得的注意资源.并通过空间映射建立注意力分配的预测模型,应用模糊层次分析的方法对模型进行结算.为验证预测模型效度,采用16名被试在飞行模拟器上开展基于异常信息恢复的工效学实验,通过眼动追踪装置记录注视点分布作为注意力分配指标.被试需要根据实验条件对主飞行显示器仿真界面中的目标信息状态进行监视,并通过驾驶杆的指定操作对异常信息进行响应.实验结果表明,注意力分配预测模型的理论结果与工效实验中注视点分布的实验结果显著相关且吻合较好,验证了预测模型的可用性.
In order to predict the pilot’s visual attention distribution, the notion of control space and resource allocation space is introduced based on the SEEV (Salient Effort Expectancy Value) model and the multi-factor model, the former describes the factors that affect the distribution of attention and the latter reflects the interest Region by the attention of the resources.At the same time, through the spatial mapping to establish the prediction model of attention distribution, the method of fuzzy analytic hierarchy process is used to settle the model.In order to verify the validity of the prediction model, 16 subjects are used to carry out anomaly based on the flight simulator Ergonomics experiment of information restoration, through the eye tracking device to record the distribution of fixation points as the attention distribution indicators.The subjects need to monitor the state of the target information in the main flight display simulation interface according to the experimental conditions, and through the designated operation of the steering column Anomaly information.The experimental results show that the theoretical results of the attention distribution prediction model are significantly correlated with the experimental results of the fixation point distribution in the ergonomic experiment and the agreement is good, which verifies the availability of the prediction model.
