Evaluation Method of Subjective Sleep Satisfaction by Measurement of Body Movement

In this study, we proposed a method for estimating the “subjective sleep satisfaction” based on measuring body movement during sleep and evaluated its effectiveness. Concretely, Kinect conducted a proposal of a method for noncontact measurement of body movement during sleep and analyzed the relations between the measured body movement data and the survey results by the subjective feeling. As a result, the subjective sleep satisfaction became high during sleep when the frequency of occurrence of small body movements, wherein only a part of the body moves, and the possibility of evaluating subjective sleep satisfaction was revealed by the measurement of the movement of the upper limbs. Therefore, it was suggested that the proposed method could be used for estimating the subjective sleep satisfaction.
