| Outline of Final Research Achievements |
Recently, a childcare environment is changing because of a growth in nuclear families. As a result, many young mothers would become nervous on childcare. Especially, a baby's night cry often causes mother's stress in early childcare. Furthermore, a baby's night cry is caused by baby's irregular sleep-wake rhythm. Therefore, we focus on a baby's sleep rhythm to decrease mother's stress. However, baby's sleep rhythm measurement is difficult to use to restraint type sensors of electroencephalograph etc. by a psychological factor of mother's. We propose estimation method of baby's sleep rhythm and sleep state by non-restraint sensor. In this study, we propose visualization of baby's sleep state by non-restraint sensor mat. We performed the sleep measurement of the baby using a sensor mat and a video camera, and visualized sleep states of active and quiet sleep by baby's vibration sound data from the sensor mat.
