为了验证数字化监控室操作员在监视过程中存在目标定位失误,并得到相关的目标定位失误率及反应时间,进行了眼动试验。试验设置了箭头、数字、图形及颜色4种目标信息,验证了目标定位延迟及目标定位失败两类目标定位失误的存在,并获得了被试对目标信息的首次进入时间及注视持续时间。通过对4种目标信息的目标定位眼动数据分析,发现不同的目标信息类型对目标信息区的眼动首次进入时间及注视持续时间的影响是显著的,对目标定位的总失误率影响也是显著的。通过SPSS软件分析发现,目标定位总失误率与首次进入时间及注视持续时间都存在线性相关关系。
In order to verify the existence of the target positioning error during the monitoring process of the digital control room operator and obtain the related target positioning error rate and reaction time, the eye movement test was carried out. The experimental results show that there are four types of target information, such as arrow, number, figure and color, which verify the existence of target localization delay and target localization failure. The first entry time and fixation duration of target information are obtained. Through the analysis of the target locating and eye tracking data of the four kinds of target information, it is found that the influence of different target information types on the first eye movement time and fixation duration in the target information area is significant, and the impact on the total error rate of the target location is also significant of. Through the analysis of SPSS software, we found that there is a linear correlation between the total error rate of target location and the time of first entry and the duration of fixation.
