煤矿不同工作面场景的安全标志显著性研究

Study on significance of safety signs in different working face scenes in coal mine

为探究煤矿不同工作面场景下,光线程度与辅助文字对煤矿安全标志的显著性影响。选取6种常见的煤矿工作面场景,在不同光线程度对比下开展有、无辅助文字的安全标志眼动实验。借助Tobii眼动仪记录35名被试者的平均瞳孔直径、眨眼频率和平均注视时间3种眼动指标,并运用SPSS19.0软件进行实验分析。结果表明:光线程度与辅助文字对煤矿安全标志均存在显著性影响,在亮光线场景下,添加辅助文字有助于提高被试者对于安全标志的识别程度;煤矿不同工作面场景下被试者对安全标志的识别程度不存在显著性差异。

In order to explore the significant influence of light level and auxiliary text on coal mine safety signs under different working face scenes in coal mines,we selected 6 common coal mining face scenes,and carried out eye movement experiments of safety signs with and without auxiliary text under the contrast of different light levels.The Tobii eye tracker was used to record the average pupil diameter,blink frequency and average fixation time of 35 subjects,and the SPSS19.0 software was used for experimental analysis.The results show that both the light level and the auxiliary text have a significant impact on the safety signs of coal mines.In bright light scenes,adding auxiliary text helps to improve the participants’recognition of safety signs;there is no significant difference in the recognition degree of safety signs among the subjects under different working face scenarios.
