Abstract
In this study, a depth analysis technique was developed to monitor user’s breathing rate, sleep position, and body movement while sleeping without any physical contact. A cross-section method was proposed to detect user’s head and torso from the sequence of depth images. In the experiment, eight participants were asked to change the sleep positions (supine and side-lying) every fifteen breathing cycles on the bed. The results showed that the proposed method is promising to detect the head and torso with various sleeping postures and body shapes. In addition, a realistic over-night sleep monitoring experiment was conducted. The results demonstrated that this system is promising to monitor the sleep conditions in realistic sleep conditions and the measurement accuracy was better than the first experiment. This study is important for providing a non-contact technology to measure multiple sleep conditions and assist users in better understanding of his sleep quality.
