【摘要】：本文主要探讨多目标搜索过程中目标搜索时间的规律和眼动行为特征。试验任务由计算机编程实现,并将字符呈现在1个24英寸的显示器上,任务要求受试者在呈现的字符中找出3个目标字符,同一组的3个目标字符之间具有较高的相似度,而不同组的目标字符和干扰字符之间具有不同的相似度。试验过程中记录了搜索时间数据和眼动数据。结果表明,目标字符与干扰字符相似度较高时注视点数量也较多;受试者在搜索过程中主要有三种眼动模式,即平行搜索模式、系列搜索模式和平行-系列搜索模式,且平行-系列搜索模式具有最好的搜索绩效,即使用平行-系列搜索模式的受试者所用的时间最短;目标呈现的顺序对于搜索绩效有明显影响;目标字符与干扰字符之间的相似度也会影响搜索绩效。
[Abstract]:This paper mainly discusses the rule of target search time and the characteristics of eye movement behavior in the process of multi-target search. The experiment task is realized by computer programming, and the characters are presented on a 24-inch display. The task required the subjects to find out three target characters in the rendered characters, and there was a high similarity between the three target characters in the same group. The search time data and eye movement data are recorded during the experiment. The results show that the number of fixation points is more when the similarity between target characters and interference characters is high. There are three kinds of eye movement patterns in the search process, namely parallel search mode, series search mode and parallel series search mode, and parallel series search mode has the best search performance. Even the subjects using parallel-series search mode take the shortest time; the order of target presentation has a significant impact on the search performance; the similarity between target characters and interference characters will also affect the search performance.
