Abstract
A sleep state management device includes a sensor that detects movement in bedding where a measurement subject is sleeping, and a control unit that calculates a peak value difference, which is a difference between adjacent peak values in a detection signal outputted from the sensor, determines that a period in which a number of times the peak value difference exceeds a threshold is greater than a predetermined value is a period in which the measurement subject has moved, and manages the sleep state of the measurement based on a result of the determination.
Claims9
A sleep state management device comprising:
- a sensor unit that detects movement in bedding where a measurement subject is sleeping;
- a peak value difference calculation unit that calculates a peak value difference that is a difference between adjacent peak values in a detection signal outputted from the sensor unit;
- a first body movement determination unit that determines that a period in which a number of times the peak value difference exceeds a first threshold is greater than a predetermined value is a period in which the sensor unit has detected movement;
- and
- a sleep state management unit that manages a sleep state of the measurement subject using a result of the determination performed by the first body movement determination unit.
A sleep state management method comprising:
- a peak value difference calculation step of calculating a peak value difference that is a difference between adjacent peak values in a detection signal outputted from a sensor unit that detects vibration in bedding in which a measurement subject is sleeping;
- a body movement determination step of determining that a period in which a number of times the peak value difference exceeds a threshold is greater than a predetermined value is a period in which the sensor unit has detected vibration;
- and
- a sleep state management step of managing the sleep state of the measurement subject using a result of the determination made in the body movement determination step.
