Audio-visual Emotion Regulation System Based on TGAM Module / 中国医疗器械杂志

OBJECTIVE@#Based on the TGAM PCB module, a system of emotion control using audio-visual feedback is designed.@*METHODS@#TGAM collects EEG information through the electrode in contact with the forehead skin. The system analyzes the user's emotion through the STM32F103ZET6 of the main control chip, and finally controls the control end of the system to regulate the user's emotion.@*RESULTS@#It can be seen from the test results that the system can precisely recognize the user's emotions, and at the same time effectively adjust the user's emotions from both audio-visual aspects.@*CONCLUSIONS@#The system has high recognition accuracy and good adjustment effect.

A Processing Method of EEG Signals Based on Second Generation Wavelet Transform and Blind Signal Separation / 航天医学与医学工程

Objective To study a processing method for EEG signals mixed with EOG and ECG signals disturbance.Methods First,the EEG was denoised by the hard threshold method,the soft threshold method,the compromise threshold method and the ? law threshold method in the second generation wavelet,and then the denoised EEG which still contained EOG and ECG was separated by fast independent component analysis( FastICA) algorithm.Results The ? law threshold method of the second generation wavelet had better denoising effect and FastICA algorithm had more ideal separate performance.Conclusion It is an effective preprocessing method for EEG in denoising with the ? law threshold method of the second generation wavelet and then in separating disturbance of independent source with FastICA algorithm.
