Human-machine interface via EMG signals derived from EEG measurement device

Abstract

This paper presents application of electroencephalography (EEG) measurement device for recording EMG signals from the arm muscles in order to generate motor shaft movements. System used for this experiment consists of electrodes primarily intended for use in electroencephalography, which are placed on person’s skin and connected to the simple EEG device. Recorded signals are forwarded to the PC in purpose of filtration using BrainBay software and later sent to the development board. Firmware in the microcontroller on this board regulates rotation of the stepper motor, whether clockwise or counterclockwise. This implementation enables real-time response to muscle contractions, thus moving the stepper motor.
