Brainwaves and electroencephalography (EEG)
Please read this disclaimer first.
This project is an attempt to create an interface between human and a machine (computer). It is well known, that with biofeedback devices (e.g. Brainmaster) it is possible to distinguish some brain states like agitation or calmness.
I believe that has a great potential and wish to contribute in this field.
First I built a simple 2-channel electroencephalograph that can measure brain waves.
The device is based on open source project ModularEEG.
Then I started my own software development named BioEra to analyze EEG and other biofeedbacks.
See pictures.
