Abstract
The present invention relates to a Steady-State Visual Evoked Potential (SSVEP)-based stimulus detection device and a method thereof. The SSVEP-based stimulus detection device may include a sensor that acquires a multichannel ElectroEncephaloGram (EEG) signal, a storage that stores a plurality of reference signals having different stimulation frequencies, and a controller that periodically determines correlation coefficients between the plurality of reference signals and the multichannel EEG signal for a reference time, normalizes the determined plurality of correlation coefficients for stimuli, determines slopes of regression lines for stimuli by performing analysis of covariance on the normalized plurality of correlation coefficients for stimuli, and detects a stimulus intended by a user according to the determined slopes of the regression lines for stimuli.
