摘要：A waking degree maintaining apparatus of this invention estimates a waking degree of a person on the basis of a correlation between brain waves and the reaction time or between the blinking frequency and the reaction time, and discriminates a drop in waking degree on the basis of the obtained waking degree. A stimulus according to the waking degree is presented to maintain the person in a waking state of a predetermined level. The waking degree of a person is recovered to a normal state, not only in a low waking degree state, but also in an over-stained state.
