BCI Alpha Wave Typing System

The system allows paralyzed patients to type, chat and use the Linux operating system

Introduction

This repository include the core algorithm.

Folder	Description
data	raw brain wave signal data acquired by record_data.py
psd_data	Power spectral density data generated from Generate_PSD_data.py
ffmpeg_stimulus_generator	a simple method to generate stable SSVEP stimulus
signal_exp	unimportant, just try signal processing API or something else

File	Description
Generate_PSD_data.py	generate Power spectral density data from data folder, then save PSD data to psd_data folder
Online_Alpha_Detector.py	Used to detect alpha brain wave in real time, if detected, then send message to Unity GUI Program via Socket
Online_MI_Detector.py	similar to Online_Alpha_Detector.py and MI stands for motor imagery
Online_SSVEP_Detector.py	similar to Online_Alpha_Detector.py and SSVEP stands for steady state visually evoked potentials
Train_Alpha_Detector.py	train neural network model for detecting alpha brain wave
Train_MI_Detector.py	train neural network model for detecting motor imagery
Train_SSVEP_Detector.py	train neural network model for detecting steady state visually evoked potentials
*.keras	the Tensorflow Keras model file, can be used to classify EEG signal at real time
read_data_and filter signal.py	Visualize the signal processing flow.
record_data.py	acquire raw EEG signal and save to data folder.
socket_server.py	unimportant, just try the Socket API.
test.py	unimportant, do something temporarily.
utils.py	Encapsulate the signal processing function, make code cleaner.
