Study on EEG monitoring information based on visual stimulation

摘要

By analyzing the relationship between EEG and the human mental state and EEG detection method, the paper designs and analyzes corresponding circuit for EEG acquisition, focuses on the analysis of the EEG signal in human mental concentration data. By adjusting the attention, the tester can be brain - machine interactive operation with the concentration degree to change the color light by the EEG detection equipment. At the same time, this paper analyzes several feasible schemes associated with visual stimulus features in EEG signals, and ultimately choose and comprehensive utilize feature extraction of EEG signals in time domain and frequency domain characteristics.
