<p><P>PROBLEM TO BE SOLVED: To provide a drunk state detector that detects precisely whether a person is drunk or not. <P>SOLUTION: A subject's heart rate is obtained (S10), his or her heart rate fluctuations are obtained based on the heartbeat conditions (S14) and his or her drunk state is detected from the relative relation between the high and low frequency components of fluctuations of his or her heart rate (S18). The subject is decided to be drunk when increase and decrease of the high and low frequency components of heart rate fluctuations are synchronous. Therefore, it is allowed to detect the subject having drunk a small amount of alcohol, and to precisely detect whether the subject have drunk alcohol or not. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
