Despite the potential of mobile electroencephalogram (EEG) devices in managing construction workers' safety, health, and productivity, deploying mobile EEG at sites is hindered by significant motion artifacts introduced by worker movements. To address this issue, the authors propose a paired electrode-and constraint independent component analysis-based denoising that adaptively suppresses EEG motion artifacts via leveraging simultaneously collected motion artifact references. The proposed denoising was compared with an advanced benchmark on an EEG dataset collected under real human motions. Results show the proposed technique's denoising performance is statistically higher than the existing advanced benchmark. The finding of this study can improve the applicability of mobile EEG to construction sites, thereby significantly contributing to management of workers' safety, health, and productivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
