Abstract
A brain-computer interface (BCI) systems permit encephalic activity to solely control computers or external devices. Accordingly, people suffering from neuromuscular diseases can highly benefit from these technologies, since a computer could allow them to perform multiple tasks, such as accessing computer-based entertainment (videos, games, books, music, movies, etc.), communication (Internet, VoIP, e-mails, text processors, speech synthesis, etc.) and means of research (computational capacity, programming languages, simulation applications, etc.). Moreover, nowadays a computer can control various electronic devices, from TVs, DVD and CD players to electric wheel chairs, elevators, doors and lights. The purpose of this chapter is to discuss the concept of brain computer interface (BCI) along with presenting its definition, description, and classification of BCI systems. Also, provides insights on the Neuroimaging modalities for BCI systems such as Electroencephalography (EEG), Electrocorticography (ECoG), and Magnetoencephalography (MEG) approaches. Moreover, this chapter addresses EEG signal processing for BCI from the different perspectives of preprocessing techniques that deal with EOG/EMG artifacts, feature extraction approaches for BCI designs, classification methods and Post-processing. Furthermore, the chapter gives a brief survey of classifiers used in BCI research along with classification performance metrics utilized for BCI systems. Finally, the chapter concludes with outlining ongoing research directions for Brain–computer interface (BCI) systems.
Quiet people have the loudest minds.
