Abstract

PURPOSE: To exactly decide a sleeping state irrespective of individual difference of a user by deciding that the person is sleeping, when one of a first pattern in which the number of breaths decreases gradually or a second pattern in which the number of breaths decreases suddenly and temporarily, and thereafter, increases and becomes stable is detected.
CONSTITUTION: As for the number of breaths, there are a first pattern in which it decreases gradually until a sleep becomes deep to some extent, and thereafter, takes a roughly constant value, and a second pattern in which it decreases extremely and temporarily immediately before sleeping, and thereafter, increases again and shows a stable value. By an arithmetic circuit 43, the number of breaths is calculated, its variation is monitored, and in the case a first or a second pattern is detected, it is decided to be sleeping. In such a way, since not only a first pattern but also a second pattern are taken into consideration, there is no individual difference at the time of deciding a sleep, and a sleep can be decided with high reliability.
