In this paper,four class motor imagery and hand movements classification has been done for brain computer interface.In this project, we proposed an automated computer platform for the purpose of classifying Electroencephalography (EEG) signals associated with left and right hand movements using a ENOBIO DEVICE.EEG signals were acquired on the Enobio device, with all 8 channels (F3, F4, FZ, P3, P4, CZ, C3 and C4) in alpha and beta rhythm in order to establish the active networks. Six volunteers were participated, the volunteers were instructed to perform motor imagery tasks and movements using both hands, and both legs. It is that EEG represents the brain activity by the electrical voltage fluctuations along the scalp using 8 Electrodes system. It uses advanced feature extraction techniques and machine learning algorithms. In this work, we aspired to find the best feature extraction method that enables the differentiation between left and right executed hand and leg movements through SVM classification algorithm. The EEG dataset used in this research was created and data was preprocessed using the MATLAB toolbox. An important part of a brain-computer interface is an algorithm for classifying different commands that the user may want to execute. The goal of this is to implement an algorithm that would be able to classify two different hand and leg movement tasks. The features such as Mean, Variance ,Standard Deviation,Discrete wavelet transform have been extracted and finally classification is done using SVM classifier and the greatest accuracy is obtained.
