Software Module for Processing EEG Signals in a Biofeedback Based System

Abstract

This paper presents the implementation of a software module applied to the field of psychophysiology that examines the causal link between the physiological parameters and the psychological state of a person. The implemented module provides the ability to process and display EEG signals in realtime and is part of a larger software system based on the biofeedback method. Signals can be displayed either in the time or frequency domain and can be subjected to a variety of processing functions. The aim of this module is to provide a reliable tool for processing and displaying brain waves in arbitrary frequency bands and to offer a platform for biofeedback training implementations that can enhance the degree of attention, concentration, relaxation and learning ability in the person participating in the training.
