工人脑力负荷对识别安全标志的视觉注意影响
The Impact of Workers'Cognitive Load on Visual Attention to Safety Signs
摘要
Abstract
In order to investigate the impact of cognitive load on workers'visual attention in recognizing safety signs,an eye tracking experimental approach was employed based on the theory of visual information processing,taking into account differences in various types of safety signs.Thirty-two participants taking the construction engineering courses were selected and divided into two groups based on their work duration.The TobbiX3-120 eye tracker was used to record participants'eye movement data,including their initial fixation time and duration of first fixation,when they were exposed to typical construction site scenarios and safety signs as stimuli.The results indicate that participants under high cognitive load exhibited weaker visual attention toward safety signs,slower information processing speed,and lower accuracy in extracting critical information.Conversely,participants under low cognitive load demonstrated stronger visual attention toward safety signs,faster information processing speed,and higher accuracy in extracting critical information.Furthermore,the type of safety sign was found to impact participants'level of visual attention,with instructional signs being more difficult to notice.关键词
