<p>PURPOSE:To allow a device to function so as to maintain a person in an optimal awakening state by providing a means for providing a prescribed stimulation, when it is decided to be the reduction in awakening. CONSTITUTION:A brain wave detecting part 51 is constituted of the part for detecting a brain wave by an electrode 2 installed in a head part from a driver 1 being a testee, and also, amplifying the brain wave by an ampoule. Also, a brain wave working part 52 works a brain wave signal from the brain wave detecting part 51 to the physical quantity required for evaluating the degree of awakening. An awakening degree estimating part 53 calculates an estimate having a deep relation to awakening, based on an awakening degree estimation parameter and brain wave band data. Moreover, an awakening degree deciding part 54 decides to what degree stimulation is provided, from the degree of awakening estimated by the awakening degree estimating part 53. A stimulation prodding part 50 provides a suitable stimulation to the driver or stops it by an instruction from the awakening degree deciding part 54. That is, an optimal stimulation quantity of its individual is clarified, and in accordance with its stimulation quantity, an effective stimulation corresponding to a physiological state is adjusted and given.</p> |
