The output state of a pulse wave optimum to the user and applied to the head of the user is automatically set while improving the wearability of the electrodes, and different output states of pulse waves can be simultaneously applied to a large number of users. A pulse wave of predetermined pattern is given to the skin near an ear of the user and/or of the back of a hand of the user to directly stimulate and activate the brain. This stimulation is significantly effective especially for colorblindness. By systematizing such a revolutionary therapy, pulse waves of different patterns can be applied to a large number of patients (users), enabling a quick, effective therapy.
