The present invention relates to a visual stimulation-based brain-computer interface apparatus and an information processing method thereof. The information processing method performed by a visual stimulation-based brain-computer interface comprises: (a) a step of extracting a gazing point of a user based on reference distance information between a display module provided with a visual stimulation and the user and calculating an overall view area based on the gazing point; (b) a step of setting a first range based on the gazing pint in the overall view area as a center view area and setting a second range excluding the first range as a peripheral view area; (c) a step of presenting a first view stimulation to the center view area based on previously measured visual fatigue and presenting a second view stimulation to the peripheral view area; (d) a step of measuring a brainwave of the user by the first or the second view stimulation and extracting brain signal feature information for a frequency band or a time band from the measured brainwave; and (e) a step of using the brain signal feature information to detect a user intention stimulation gazed by the user and outputting the detected user intention stimulation by the display module.
