<P>PROBLEM TO BE SOLVED: To easily generate wakeful state data. <P>SOLUTION: This wakeful state data generating device includes a first computing section, a first estimating section, a second computing section, a second estimating section, and a generating section. The first computing section computes a variation value of heartbeat interval from heartbeat signals of a subject. The first estimating section estimates maximum spectral density in the wakeful state of the subject from the variation value computed by the first computing section based on the correlation between a prerecorded variation value and maximum spectral density in the wakeful state. The second estimating section estimates a maximum frequency in the wakeful state of the subject from a heart rate computed by the second computing section based on the correlation between a prerecorded heart rate and a maximum frequency in the wakeful state. The generating section generates the wakeful state data including the maximum spectral density in the wakeful state estimated by the first estimating section, and the maximum frequency in the wakeful state estimated by the second estimating section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
