Fall detection on the road

While for an automatic and autonomous indoor fall detection an enormous amount of different sensors is conceivable, for an outdoor fall detection only wearable sensors are applicable. For practical uses cases, it would be very beneficial if after a detected fall a medical alert is initiated. In indoor environments, a base station connected to a telephone line can handle these calls. On the road, this can be achieved by mobile phones or smartphones. In this paper we first estimate the suitability of several systems for an outdoor fall detection. Then, we propose a system for a mobile and stationary fall detection and alerting system. We implemented and evaluated this system, which is consisting of a smartphone and a wireless sensor node.
