Key result
An EEG/GSR machine learning pipeline classifies mental stress in refugees with ~87% accuracy.
Why the study?
An influx of refugees prompted the development and evaluation of software utilizing mobile EEG and GSR sensors to recognize and alleviate acute stress.
Can a machine learning pipeline utilizing mobile EEG and GSR sensors accurately classify mental stress levels in refugees undergoing Virtual Reality stress-reduction sessions?
Observational (n=55)
Can a machine learning pipeline utilizing mobile EEG and GSR sensors accurately classify mental stress levels in refugees undergoing Virtual Reality stress-reduction sessions?
A machine learning pipeline using mobile EEG and GSR sensors can accurately classify stress levels in refugees, offering a potential support tool for mental health professionals.
May support objective stress monitoring in refugees; hypothesis-generating and requires prospective validation before clinical use.
This paper introduces a study on stress recognition utilizing mobile EEG and GSR sensors. The research involved collecting samples from a group of 55 refugees who participated in Virtual Reality stress-reduction sessions. The timing of the study coincided with an influx of refugees, prompting the development of software specifically designed to alleviate acute stress among them. The paper focuses on presenting an EEG/GSR signals pipeline for classifying stress levels, emphasizing selecting the most informative features. The classification process employed popular machine learning methods, yielding results of 86.7% for two-stress-level classification and 82.3% and 67.7% for the three- and five-level classifications, respectively. Most importantly, the positive impact of the system has been proven by subjective assessment in alignment with objective features analysis. Such a system has not yet reached the level of autonomy, but it can be a valuable support tool for mental health professionals.
