発明の名称 (英語) SLEEPINESS ASSESSMENT DEVICE
発明の概要(英語) Provided is a sleepiness assessment device that: sets an average heart rate (HR) as a sleepiness determination value (P1) (S130); sets the standard deviation (.sigma.) of a respiration interval (RespI) over the period of one minute as a sleepiness determination value (P2) (S150); sets a value obtained by dividing the summation of the squares of average heartbeat intervals (RRIavg), when a heartbeat interval (RRI) becomes shorter (i.e., when the RRI count value (Xi) is 1), with the period of one minute as a sleepiness determination value (P3) (S190); sets a value obtained by averaging the volatility, when the respiration interval (RespI) becomes longer (i.e., when the RespI count value (Yi) is 1), as a sleepiness determination value (P4) (S210); sets a value obtained by the summation of the products of the sleepiness determination values (P1 to P4) and the respective weight coefficients (a to d), as a sleepiness determination value (P) (S220); determines that a subject is highly alert when the sleepiness determination value (P) is less than 0 (S240); and determines that a subject is less alert when the sleepiness determination value (P) is 0 or more (S250).
