System and method for detecting a fall of a person

Abstract

The invention relates to a system for detecting a fall of a person. The system comprises a stationary sensor located at a fixed position relative to the person and a wearable sensor worn by the person that both may report a fall of the person independently of one another other. Furthermore, the system comprises a line-of-sight detection unit that is configured to determine whether the wearable sensor is in line-of-sight of the stationary sensor. For detecting a fall of the person, the system's fall detection unit takes into account a report of a fall as provided by one or both of the stationary sensor and the wearable sensor. In addition, for detecting a fall, the fall detection unit takes into account an absence or presence of a line-of-sight between the wearable sensor and the stationary sensor. Thereby, it is possible to increase the reliability of detecting a fall, in particular, if only one of the wearable sensor and the stationary sensor reports a fall.
