【摘要】：为研究塔台管制员在不同工作负荷下注视转移模式的差异,构建了模拟塔台管制的眼动试验平台,根据航班流量密度设计简单和困难2组试验。利用NASA-TLX量表评价被试者在2组试验中的工作负荷,应用离散时间马尔科夫链(discrete time Markov chain,DTMC)计算被试者在兴趣区间的注视一步转移概率,利用SPSS软件分析2组试验中被试在各兴趣区组的注视一步转移概率差异性。结果发现:被试者的工作负荷随航班流量密度增大而增大。航班流量密度增大后,被试者在场面监视雷达区内的注视转移显著增加,由场面监视雷达区向空域监视雷达区和指令栏区的注视转移显著减少,在进程单区内的注视转移显著增加。管制员的注意力更容易向能获取更多信息的区域发生转移。
[Abstract]:In order to study the differences of gaze transfer modes of tower controllers under different workloads, an eye movement test platform was constructed to simulate tower control. According to the flight flow density, two groups of simple and difficult tests were designed. NASA-TLX scale was used to evaluate the workload of the subjects in the two groups, and the discrete time Markov chain (discrete time Markov chain,DTMC) was used to calculate the fixation one-step transition probability of the subjects in the region of interest. SPSS software was used to analyze the difference of one step fixation transition probability between the two groups. The results showed that the workload of the subjects increased with the increase of flight traffic density. With the increase of flight traffic density, the fixation transfer in the scene surveillance radar area increased significantly, and the gaze shift from the scene surveillance radar area to the airspace surveillance radar area and the command bar area decreased significantly. Fixation transfer increased significantly in the single zone of the process. Controllers are more likely to shift their attention to areas where more information is available.
