Portable EEG recording system for BCI application

Abstract

Before few decades disabled persons were not able to perform daily tasks such as turning the light on, making a phone call, and even controlling the TV. Disability was an obstacle therefore disabled individuals needed daily monitoring and service. With the evolution of computation power and the progress in neuronal studies, modern technology and science managed to overcome the human disability for example the ability to walk was restored with the help of fully automated prosthetic legs controlled by brain signals.This work aimed to aid the disabled people that are not able to simply grasp a TV remote control to switch the TV on or browse through the channels; therefore a brain machine interface must be implemented. Low cost portable ElectroEncephaloGraph (EEG) system is designed and tested that allow a person to control the TV through his eye blinks. An overall accuracy of 90% has been obtained in testing 5 TV control events. The total price of the prototype did not exceed the 60 USD.
