Abstract
A control method and a sense organ testing method based on steady state brain evoked response include the steps of: generating one or multiple stimulus signal(s) varying in various frequencies that can be sensed by sense organs of human subject; detecting the brain electrical signal of stimulated human subject; analyzing the detected brain electrical signal to extract the characteristic physical quantity corresponding to the frequency of a stimulus signal; and, according to the characteristic physical quantity, controlling a specific device corresponding to the stimulus signal to perform a preprogrammed operation or objectively evaluating the condition of the sense organ of the subject.
