The Department of Electronics and Communication Engineering of TJS Engineering College, Chennai, India has a new paper on Women Safety System using iBeacon Technology.
It describes a system that uses iBeacon to provide tracking of women when out alone. As it uses iBeacon, it is presumably for use where GPS doesn’t work. Also, while not mentioned, it might equally be used for all vulnerable people including lone workers, young, old and disabled.
The system consists of a wearable belt that tracks location and sends alerts via cellular connection. It uses heartbeat, sound and pressure sensors to detect abnormal situations.
