Abstract

It has been known that the particular brain waves are induced when a human concentrates. In our study, we aimed to analysis the brain waves related to human concentration using visual stimulus to induce the concentration. The visual stimulus tasks were presented to subjects for concentration. We measured EEG signals with several channels and analyzed the signals into several frequency bands. In the measured EEG signals, we analyzed to focus on theta waves, SMR waves and mid-beta waves. Therefore we presented the results to investigate characteristics of the EEG signals related to the human concentration.

인간은 집중할 때 유발되는 특정한 뇌파가 있는 것으로 알려져 있다. 본 논문에서는 인간의 집중과 관련된 뇌파를 분석하는 것을 목표로 하여, 집중을 유발할 수 있는 도구로 시각자극을 설정하였다. 즉 시각자극으로 구성된 과제를 제시하여 피험자가 집중할 수 있도록 하였다. 피험자로부터 유발되는 뇌파는 전극의 위치에 따른 채널별로 계측하였고, 계측한 뇌파는 주파수대역별로 나누어 분석하였다. 그 중에서도 특히 SMR, Mid-beta, Theta파에 해당되는 주파수대역의 파워 스펙트럼으로 분석하였고, 그 특성을 분석한 결과를 제시하였다.
