A Posture Detection System using Consumer Wearable Sensors

Having the correct postures in many situations, such as standing, sitting, playing a sport, and working, makes our bodies function properly and keeps us healthy. The advancement of sensor technology allows us to quickly measure our posture in every scene using consumer-grade devices such as a wrist-worn type tracking sensors, smartphones, and shoes embedded with several kinds of sensors. It is not difficult to detect correct postures of athletes who can train at fully equipped facilities. However, for ordinary users, it is necessary to use a combination of such consumer portable devices for checking proper postures during daily exercise. In this study, we present a posture detection system using sensors embedded in consumer portable devices, for the purpose of posture checking. Experiments are performed to illustrate the feasibility of our system by the use of some exercise motions.
