Abstract: A way of information presentation is proposed for the problem of searching efficiency in man-machine interface. Experiment-Builder is used to present stimulus which is composed of “T” and after rotated “T”. Eye-link2000 is used to get the amount of saccades in each trail. The assessment method of within-group is referenced to process data, and the results show that separating all information into two parts to display can improve efficiency of search, but the improved degree is different in different conditions.

摘要： 针对人机界面信息搜索效率的问题，引入了一种分次呈现所有信息的方法。利用Eye-link2000自带软件Experiment-Builder编制实验程序分次呈现由字母“T”及其旋转后组成的刺激，获取被试搜索靶子过程中的扫视次数。借鉴之前文献中的评估方法对数据进行处理，结果证实了分次呈现所有信息能够有效提高信息的搜索效率，但在不同条件下，搜索绩效提高的程度不一致。
