Assessing Construction Workers' Vigilance Level Through Wearable Electroencephalography System

Construction industry requires constant caution on construction labors when they expose to hazardous environments. Although received fundamental safety training, construction workers tend to insensitive to hazards because of their long time exposures to risks. Many construction workers take unsafe behavior when they wrongly estimated the potential risks. Therefore, the discrepancy between the environment risks and workers' perceived risks is the major cause of unsafe behaviors. However, current assessing approaches are subjective and post-hoc. In this paper, we proposed a wearable Electroencephalography (EEG) system to quantitatively and objectively assess the construction workersÕ vigilance level for perceived risks. With such data acquisition approach, the construction workers' risk perception can be further understood and guide the safety training programs in future.
