General Concepts on Electroencephalography-Based Brain-Computer Interface Systems

Abstract

Brain-computer interface (BCI) technology primarily helps the physically challenged people get in touch with the outside world using the brain signals. Because of the simplicity of the electroencephalogram-based BCI methods, a number of researchers have shown interest and have done a lot of work in this field. However, for a common man, to understand the concept of BCI, the article presents a fundamental model with a brief summary of the various steps involved in the process of the whole system. Finally, some research work done to date has also been discussed. The whole article will help a person to understand the basic concepts of the electroencephalogram-based BCI system going through the model to the discussions.
