Title:
状態推定装置及び状態推定方法
Document Type and Number:
Japanese Patent JP7070512
Kind Code:
B2
Abstract:
A condition estimation device calculates different types of index values using biological information of the user, and estimates the relax level of the user using relax levels set according to change tendencies of the index values. As the index values, at least two of a heart rate of the user, an α wave time content ratio indicating a ratio of a time period during which an α wave of the user is generated to a unit time period, and an integrated value of high frequency components of the heart rate of the user by performing a frequency analysis to a change in the heart rate of the user are calculated. The relax level of the user is estimated using the relax levels set according to the change tendencies of the calculated index values.
