| 摘 要： | 以不同字数、不同间距、不同方向的文字序列为刺激物,以眼动仪为主要试验仪器对驾驶员视认交通标志文字信息的眼动特征进行了分析,并得到了全局关注和特定信息搜索2种视认方式下不同字数文字信息的注视时间,采用响应面法回归了不同条件下的眼跳速度方程,对比了注视时间和眼跳时间的比例关系,发现眼跳时间大约为注视时间的1/5.

| Abstract: | With the help of eye-tracker,the eye movement features on the text message from traffic sign are analyzed based on the word list search task,in which words with different length were arranged in eight orientations and six spacing respectively.The fixation duration under different recognition mode is calculated by using statistical analysis.The saccade speed of different orientations and spacing is identified with the help of response surface method.The comparison is made between the average fixation duration and the average saccade time and the results show that the average saccade time is just the one-fifth of average fixation duration. |

| Keywords: | eye movement fixation point fixation duration saccade speed |
