| Outline of Final Research Achievements |
We constructed methods for estimation of body sinking distance and postures on an air mattress using pressure distribution sensors. The body sinking distance is estimated based on investigated non-linear relationship between pressure values and sinking distances. The posture is estimated by using machine learning technique. The distance estimation method was evaluated based on the dataset that includes body sinking distance during head of bed elevation. We also prepared dataset about posture dataset on supine, right and left lateral position, 30-degree and maximum inclination of bed. The experiment demonstrated that our method had good performance.
