Pattern Activities Identification in the Framework of Medical Nursing Home Using Infrared Sensors (original) (raw)

This work propose a remote healthcare monitoring system designed to derive elderly’s activities of daily living and distress situation in Nursing Home environments through a set of pyroelectric infrared sensor placed in the rooms. We aim to infer from the nursing home environment information as the exits and entries in the room, presence of caregivers and activities as night rounds, sleeping, eating, care-giver intervention. Thank to the sensors emplacement in the present case is possible to extract patterns regarding paths performed inside the room. Based on these patterns, we propose in a first step, a finite state model that represents the behavior of only one person moving inside the room. Through accomplishing of this model, we can derive some information as resident tracking, presence of care-givers, entries and exits. In previous work we have used the Dempster-Shafer theory (DST) based on static and dynamic model called Evidential Networks [11] in order to take into account t...
