Abstract：Currently , little attention is paid on the details of the research on visual search .Security screening is a special visual search process , and understanding this process is the premise of improvement . It is necessary to learn the visual search details in security screening .To test the rationality of the current security principle ( from difficult to easy , from complex to simple ) and the difference between the two groups, two groups (screener's group and student's group) are selected to conduct a screening simulation experiment.Based on statistical analysis , by combining with the characteristics of the two groups , a non-parametric test is applied to analyze the differences on some parameters .Expert grading method is used to analyze the searching process .Results reveal that there are significant differences on fixation time percent , saccade distance , and judgment accuracy between the two groups .The screener's correct rate is 28.7%higher than student's, while screener's fixation duration is shorter .There are more than 75%of the fixation points lasting for less than 200 ms, while student's is about 17%.The screener's group tends to do system-ic searching under the principle of screening , while the student's group prefers random searching .
