Method And Apparatus For Determining Sleep State Using Biometric Information And Motion Information
A sleep state determination method using biometric and motion information includes acquiring motion information of a user using a motion sensor; determining a primary sleep state of the user based on the acquired motion information; acquiring biometric information of the user using a biometric sensor when the primary sleep state is determined; and determining a final sleep state of the user by combining the acquired biometric information and the primary sleep state.

- 1. A sleep state determination method using biometric and motion information, the sleep state determination method comprising:
acquiring motion information of a user using a motion sensor; determining a primary sleep state of the user based on the acquired motion information; acquiring biometric information of the user using a biometric sensor when the primary sleep state is determined; and determining a final sleep state of the user by combining the acquired biometric information and the primary sleep state.
- 10. A sleep state determination apparatus using biometric and motion information, the apparatus comprising at least one processor and a memory storing at least one instruction executed by the at least one processor, wherein the at least one instruction is configured to:
acquire motion information of a user using a motion sensor; determine a primary sleep state of the user based on the acquired motion information; acquire biometric information of the user using a biometric sensor when the primary sleep state is determined; and determine a final sleep state of the user by combining the acquired biometric information and the primary sleep state.
- 19. A sleep state determination method using biometric information, the sleep state determination method comprising:
acquiring biometric information of a user using a biometric sensor; calculating a heart rate variability by analyzing a photoplethysmography (PPG) signal included in the biometric information; comparing the calculated heart rate variability with a predetermined normal heart rate variance; and determining a sleep state of the user based on a result of the comparison.
