Brain-Computer-Interface

Aim:

Brain-computer interface (BCI) is a technology that allows communication between a human brain and an external technology. The main aim is to analyse and accurately classify the Electroencephalography (EEG) signals which are used to record electrical activity of the brain. The objective of this project is to design and implement a system for monitoring EEG signals and to classify them with the help of different classifiers. BCI systems build a communication bridge between human brain and the external world eliminating the need for typical information delivery methods.
