Under the effects of fatigue, a worker becomes more vulnerable to environmental and occupational hazards, compromising safety of the operations. Advancements in wearable technology now allow for the quantitative detection and measurement of the brain’s electrical activity and with predictive capacities can provide real-time feedback to users on their fatigue level. However, few field studies have assessed the workplace implementation of such devices. Therefore, the purpose of this study was to address these gaps by evaluating a real-time live feedback wearable EEG fatigue detection system in the field. Presented by Emily Tetzlaff.
