Abstract: A method for recognizing blink and eye movement based on electroencephalogram (EEG) and a system thereof are disclosed. The method includes measuring a subject's EEG-based electrooculogram (EOG) signal (hereinafter referred to as “EOG signal”) using three electrodes connected to an EEG head cap. The method further includes performing potential blink detection and zero crossing detection using the EOG signal, and generating a plurality of parameters used for blink and eye movement classification using the EOG signal depending on presence or absence of the potential blink and the zero crossing. In addition, the method further includes classifying the blink and up/down/left/right eye movements of using the plurality of parameters.

Abstract: Disclosed is an apparatus for a motor imagery training, which includes a measuring unit that measures a brain signal while a user performs a motor imagery training, a preprocessing unit that performs preprocessing with respect to the brain signal, a feature extraction unit that selects a time period including information related to a motor imagery from the preprocessed brain signal and calculates feature data corresponding to the brain signal of the selected time period, and a classification unit that classifies the brain signal into one of a plurality of classes based on the feature data, and the motor imagery training is any one of a first training in which the user imagines moving a body part and a second training in which the user imagines feeling a somatosensory stimuli of a tangible object using the body part.
