【摘要】：目的：研究主视眼与非主视眼的在文字阅读和图片搜索任务中的眼动过程的异同。方法：实验A：20人分别应用主视眼、非主视眼和双眼各阅读难度相同的3段文字,并且回答相应问题；实验B：20人分别应用主视眼、非主视眼和双眼完成难度相同的3组图片搜索任务,并且回答相应的问题。应用加拿大SR Research公司的SR Research EyeLink2000眼动仪记录研究过程中的研究眼的各项眼动指标。结果：文字阅读任务中问题回答正确率为94.7%,主视眼和非主视眼各项观察指标均无显著差异。图片搜索过程中问题回答正确率为95%,主视眼与非主视眼之间平均注视时间无统计学差异(P=0.210)；主视眼与非主视眼之间总注视时间无统计学差异(P=0.534)；主视眼与非主视眼之间总注视次数无统计学差异(P=0.880)；双眼注视瞳孔大小小于单眼搜索时的瞳孔大小,差异具有统计学差异(P0.001)。双眼平均注视时间和主视眼平均注视时间无统计学差异(P=0.082),但小于非主视眼搜索时间,差异有统计学意义(P=0.026)。双眼总注视时间小于单眼总注视时间,差异有统计学意义(P0.01)。双眼总注视次数小于单眼总注视次数,差异具有统计学意义(P0.05)。结论：近距离(91cm)工作中,无论是文字阅读还是图片搜索,主视眼与非主视眼的眼动过程均无明显差异。而视觉搜索时双眼视相对于单眼视有更高的工作效率。
[Abstract]:Aim: to study the similarities and differences of eye movement in text reading and image searching between primary and non-primary eyes. Methods: the subjects of experiment A: 20 were treated with 3 paragraphs with the same reading difficulty in primary eye, non-primary eye and both eyes, and the corresponding questions were answered, and the subjects of experiment B: 20 were treated with primary eye, respectively. Non-primary eyes and eyes completed the same difficulty of 3 groups of image search tasks and answered the corresponding questions. Using SR Research EyeLink2000 eye movement instrument of SR Research Company of Canada to record the eye movement indexes in the course of the study. Results: the correct rate of answering questions in the reading task was 94. 7%, and there was no significant difference between the main eye and non-primary eye. In the course of image search, the correct rate of answering questions was 95%. There was no statistical difference in the mean fixation time between the main eye and the non-main eye (P0. 210), but there was no statistical difference in the total fixation time between the main eye and the non main eye (P0. 534). There was no significant difference in the total fixation frequency between the primary eye and the non-primary eye (P0. 880), but the size of the binocular gaze pupil was smaller than that of the monocular search (P0.001). There was no significant difference in the mean fixation time between the two eyes (P0. 082), but the mean fixation time was less than that of non-primary eye search (P0. 026). The time of binocular total fixation was less than that of monocular fixation (P 0.01). The number of binocular total fixation was less than that of monocular total fixation, the difference was statistically significant (P0.05). Conclusion: there is no significant difference in eye movement between primary eye and non-main eye in close distance (91cm) work, whether in text reading or image searching. In visual search, binocular vision is more efficient than monocular vision.
