Artifacts' roaming beats recognition for estimating care activities in a nursing home

摘要

This paper describes an approach to estimate the activity being performed by caregivers in a nursing home. The approach is based on information gathered from a workplace study conducted in a nursing home, in which 400 hours of detailed observation caregivers' activities were recorded. Automatic identification of objects based in composite correlation filters was implemented in order to generate a descriptive behavior of objects. When the behavior of the artifacts related with the activities is validated, the estimation of an activity is found. The activities estimated with a 92.72% of accuracy (on average) include hygiene, feeding and taking vital signs.
