为了研究不同工龄煤矿作业人员对警示语标识的视觉注意特征,将以字体颜色和形状为自变量的警示语标识图片作为视觉刺激材料,利用EyeLink Ⅱ型眼动仪记录了24名有煤矿工作经验的本科生观看这些图片时的注视点数和首次注视时间等眼动数据,用SPSS16.0分析了首次注视时间和注视点数。基于视觉注意理论进行统计分析,结果表明:1)煤矿作业人员的工龄越长,对警示语标识的注意程度越大;2)煤矿作业人员的工龄越大,对警示语标识的识别越容易;3)红底白字隶书的警示语标识的最佳组合不是国家标准中采用的组合。
The purpose of this study is to identify and define the characteristic effects of the warning signs in different shapes and colored fonts on the miners of different service age groups in hoping to promote the introduction of the eye-tracking technology to the field of warning signs design. For the said purpose, we have taken the drawings for the font shape and color of warning signs as the visual stimulus testing samples while choosing 24 subjects in a service age groups ranging from 20 to 38 years (average service age of 27.2) in the simulation-testing experiment. In the testing process, we have made careful recordings of the eye movement parameters, such as the fixation count and the first fixation dura- tion via an Eyelink Ⅱ eye tracker, whieh in a position of giving response of a person to the visual attention and its conversion. What is more, we have also adopted the single factor variance analysis (ANOVA) to analyze the data coming from the various kinds of parameters of the eye movement. In addition, we have also adopted the visual attention theory to our study so that it is possible to identify and visualize the degree of the attention of the subjects in all the parameters. The results of our experimental test reveal the characteristic features from the point of view of the viewers : ( 1 ) The longer the service age of the miners, the stron- ger or sharper the degree of attention to the warning signs; (2) The longer service period the miners experience, the more prompt for them to identify the warning signs; (3) The warning signs of the national standards do not seem to be the best or idealistic, excerpt for the Lishu bold-faced signs in the red color as a back- ground. The said testing results have been achieved by us because we have obtained enough eye movement parameters from the simulation experiment of the subjects, for they are objective and quantitative in nature, which can be said more credible and influential than the previous ones as a kind of objective evidence.
