Abstract

In our daily life, quality of sleeping is closely related to happiness index. Whether or not people perceive sleep disturbance as a chronic disease, people complain of many difficulties, and in their daily life, they often experience difficulty breathing during sleep. It is very important to automatically recognize breathing-related disorders during a sleep, but it is very difficult in reality. To solve this problem, this paper proposes a mobile-based non-contact sleeping monitoring for health management at home. Respiratory signals during the sleep are collected by using the sound sensor of the smartphone, the characteristics of the signals are extracted, and the frequency, amplitude, respiration rate, and pattern of respiration are analyzed. Although mobile health does not solve all problems, it aims at early detection and continuous management of individual health conditions, and shows the possibility of monitoring physiological data such as respiration during the sleep without additional sensors with a smartphone in the bedroom of an ordinary home.

우리의 일상생활에서 양질의 수면은 행복 지수와 밀접한 관계가 있다. 사람들은 수면 장애를 만성 질환으로 인식하든 아니든 많은 어려움을 호소하고 있으며 일상생활에서 수면 중에 호흡 곤란을 경험하는 경우가 종종 발생한다. 수면 중에 호흡 관련 장애를 자동으로 인식하는 것은 매우 중요하나 현실적으로 매우 어렵다. 본 논문은 이러한 문제를 해결하기 위해 가정에서 건강관리를 위해 모바일 기반의 비접촉 수면 모니터링을 제안한다. 수면 중 호흡 신호는 스마트 폰의 소리 센서를 이용하여 호흡 신호를 수집하고, 신호의 특징을 추출, 호흡의 주파수, 진폭, 호흡의 주기, 호흡의 패턴을 분석한다. 모바일 건강이 모든 문제를 해결하지는 못하나 개인의 건강 상태의 조기 발견과 지속적인 관리를 목적으로 하고, 일반 가정의 침실에서 스마트 폰으로 추가 센서 없이 수면 중에 호흡과 같은 생리학적 데이터 모니터링의 가능성을 보여준다.
