Smart bracelets: Towards automating personal safety using wearable smart jewelry

Ensuring personal safety and detecting physical assaults are critically important issues. During an assault, victims often have no time to call for help using their mobile phones. Most panic button type emergency call devices also require actively pressing a button to contact emergency services. The requirement of active intervention by the victim (through dialing 911 or pressing a button) reduces the effectiveness of the service for ensuring personal safety. To resolve this problem, we use the notion of a smart wearable device, in the form of a smart jewelry bracelet, to automatically sense, detect, and identify physical assault. The smart bracelet uses a multitude of sensors and machine learning to detect an assault as it takes place and then proceeds to contact emergency services and take a series of protective actions. In this demo, we will demonstrate the smart jewelry bracelet and show its usability and effectiveness in providing a low-cost, practical, and usable tool for preventing physical assault and attacks, as well as helping elderly users.
