METHOD AND APPARATUS FOR DETERMINING A FREQUENCY BAND AND ILLUMINANCE ACCORDING TO THE SLEEPING STATE, AND PROVIDING MUSIC ACCORDING TO THE DETERMINED FREQUENCY BAND AND LIGHTING ACCORDING TO THE ILLUMINANCE

摘要

Disclosed are a method and apparatus for determining a frequency band and illuminance according to a sleeping state, and providing music according to the determined frequency band and lighting according to the illuminance. An apparatus for determining a frequency band and illuminance according to a sleep state and providing music according to the determined frequency band and illumination according to the illuminance, at least one processor; and a memory for storing instructions for the at least one processor to perform at least one operation. The at least one operation may include: acquiring biometric information of a user measured using a wearable device, and acquiring image information of the user photographed using a camera; determining a first sleep state by inputting the image information into a convolutional neural network (CNN); determining a second sleep state based on a motion signal included in the biometric information; determining a third sleep state based on a photo-plethysmograph (PPG) signal included in the biometric information; converting the first sleep state, the second sleep state, and the third sleep state into first to third sleep state vectors with reference to a first predefined matching table, respectively; inputting the converted first to third sleep state vectors into a pre-supervised learning recurrent neural network (RNN)-based artificial neural network; obtaining a final sleep state vector indicating the final sleep state of the user as an output of the artificial neural network; and selecting lighting and music corresponding to the final sleep state vector, wherein the selecting comprises selecting music having a lower main band of frequency as the determined final sleep state is closer to REM sleep, and the final sleep state As the sleep state is closer to the awakening state, music with a higher main frequency band is selected.
