AbstractConstruction accidents are more frequent and serious than accidents in other industries. To prevent safety events from occurring, construction workers must be able to recognize construction hazards. In light of this, the goal of this study was to conduct feasibility study on the use of biometric responses to assess the hazard recognition of construction workers in an immersive virtual reality (IVR) environment. Eye-tracking and electroencephalogram (EEG) data were gathered from 30 construction workers in total in an IVR environment for the fall of the double scaffolding. The absolute difference between the means of two groups—(i) fixation group, which included participants who were staring at a dangerous area (i.e., the area of interest; AOI) and (ii) non-fixation group, which included participants who were not—was calculated using the Wilcoxon signed rank test. There were significant differences between groups in two measures of biometric responses, namely pupil diameter and fatigue. In other words, in the fixation group, pupil diameter and fatigue level increased. From a practical standpoint, it is expected to create a safer work environment by employing biometric response to objectively assess the hazard recognition of construction workers and to provide personalized protective equipment depending on their skills.
