Body-worn fall detection systems typically make use of on-board inertial sensors such as tri-axial accelerometers, gyroscopes, and suchlike. A combination of features derived from these signals is used to detect whether a fall has occurred at any given moment. Optionally, other sensors such as a pressure sensor can be employed to detect height changes.

Ambient-based approaches to fall detection typically employ a number of sensors placed throughout a coverage area of relevance such as the subject’s premises or the clinical environment such as a hospital. These sensors include, but are not limited to video cameras and passive infrared (PIR) sensors.

Further, simple leash-based devices are known which are arranged as breakaway detection devices and may detect undesired removals from a defined location or range which triggers an alert. However, these devices are often experienced as considerably uncomfortable, error-prone and also somewhat motion restricting. Further, a breakaway-based fall detection device is basically not capable of discriminating a (horizontal) moving-away event from a (vertical) fall event.
