Brain-Computer Interface Artifact Removal

Abstract

The purpose of a brain-computer interface, also known as a BCI, is to create a communication channel that converts human intention into a control signal for an output device using a brain signal, such as an electroencephalogram (EEG). In addition, artefacts are undesired potentials that helps to process the signals (EEG), with the majority of originate outside signal of the cerebral cortex. Regrettably, they have the ability to alter the form of neurological phenomena that is used to operate a BCI device. They also carry the risk of inadvertently and it can lead to the device which is being controlled in a manner that was not intended. As a result, it is necessary to steer clear of, disregard, or get rid of artefacts in the recordings of brain signals. The origin of artefacts can be traced back to both physiological and non-physiological processes. The different signals are monitored and compared for the better conclusion.
