Patients Behaviour Monitoring Inside a Hospital Garden: Comparison Between RADAR and GPS Solutions

Monitoring the behaviors of inpatients with reduced cognitive abilities within an area of a hospital can provide important information on how patients live in that space and which part is of most interest. In this paper two different techniques are applied to perform this monitoring in an outdoor space; the former is based on the GPS positioning and timing, and the subjects must wear a suitable device, while the latter is based on a non-contact radar technology. Radar sensors are in fact nowadays very powerful even for medical applications and can be used to monitor patients within environments. In this work, the behaviors monitoring of the people inside the garden of a retirement house is considered. The two different techniques are used for tracking the subjects and the results are compared.
