Abstract:
In the present project, a new Electroencephalogram (EEG) Brain Computer Interface (BCI) has been implemented, the BCI is Steady State Visual Evoked Potential (SSVEP) based, namely, when the user stares to an objective that is blinking at a defined frequency, this same frequency should appear on the spectrum of the EEG when measuring on the occipital lobe. The circuit has been designed and made using Sallen-Key Filters, Amplifiers and the Arduino MKR1010 microcontroller. It has also been tested an implemented a self-new algorithm for the detection of the correct SSVEP frequency.
