Title:
SLEEP CARE SYSTEM USING FRAGRANCES
Document Type and Number:
WIPO Patent Application WO/2021/210740
Kind Code:
A1
Abstract:
This sleep care system using fragrances comprises: a fragrance diffusion device to which first to n-th fragrance capsules are mounted; a servomotor that rotates by a reference angle each time a reference time passes; a first lidar; a second lidar; and a sleep evaluation module. The first lidar and the second lidar are mounted to the servomotor so as to be oriented in different directions, measure distances to different body parts of a sleeping user each time the servomotor rotates by the reference angle, and generate first distance data and second distance data. The sleep evaluation module determines a sleep score on the basis of the first distance data and the second distance data. The fragrance diffusion device individually controls the emission intensity of fragrance materials of each of the first to n-th fragrance capsules on the basis of the sleep score.
