The stimulus setting data is made independently so that stimuli applied according to headache, brain fatigue, emotional state, or physical condition can be appropriately adjusted. The other function of the stimulus setting data is to allow perceptual stimulation to be applied. Cognitive stimulation refers to stimuli applied to inform the user that stimuli are being applied or to increase the effect of stimuli, and may be applied to other types of stimuli applied after a certain period of stimulation, other stimuli, Irregular stimulation or interruption of stimulation. If the same kind of stimulus is continuously applied to the defined area, the effect of stimulation may be reduced and the user may not be aware that the stimulus is being applied. In such a case, when the stimulus is applied to the other region, or when the stimulus of the different kind or the stimulus of the different magnitude is applied, the effect of the stimulation is improved, so that the user can recognize the state of stimulation. The cognitive stimulation can be made in a random manner and cognitive stimulation can be made in such a way that any time is selected from a number of pre-established stimulus types, stimulus sites, and stimulus sizes. And the thus generated cognitive stimulation generating method can be stored in the stimulus setting data and can be generated by the stimulation control unit 11 through at least one of the stimulation electrodes 151 to 15N or the cognition stimulation electrode arranged independently .

Therefore, depending on the contact state of the stimulating electrodes 151 to 15N, the manner in which the stimulation is induced needs to be determined. The contact state of the stimulating electrodes 151 to 15N with respect to the human body can be detected by a detection unit such as the contact detection unit 121, for example. And a contact table for the contact state of the stimulating electrodes 151 to 15N can be made by the contact table unit 12 in accordance with the detection information detected by the contact detection unit 121. [ Based on the contact table, the stimulation setting unit 13 can determine how the stimulation is applied to the stimulation electrodes 151 to 15N. For example, the stimulation electrodes 151 to 15N disposed at different positions can alternately apply a stimulus, and the magnitude of the stimulus can be set to change with time. The contact state can be periodically detected by the contact detection unit 121, and the contact table can be updated in accordance with the contact detection information. The contact table may include a contact state or a contact area of each stimulating electrode with respect to the human body, and the stimulating electrodes 151 to 15N may have an area contact electrode structure formed such that a plane of a certain size contacts the human body.
