Facilitating communication and computer use with EEG devices for non-vocal quadriplegics

This paper tackled the problem of establishing a computer brain interface using an Electroencephalography device for the purposes of interfacing with a computer using software developed in house for non-vocal quadriplegics. The hardware used was an Emotiv EEG that was used with a novel interface in order to establish some form of voice communications. The Emotiv headset was then tested using some basic tests to observe any electromyographic artifacts that could be extracted using Independent Component Analysis based techniques. Software was then designed to address the problems that non-vocal quadriplegics face when it comes to communications with others. The software that was developed achieved good success, allowing for a total of two mouse click actions and total mouse control, providing a way to use a computer normally and communicate effectively. The work is significant in the way that a quadriplegic, a person who can´t do much with a computer, can now use this suite to regain a bit of normality to their lives.
