The present disclosure pertains to the field of personal safety systems, and particularly to wearable electronic devices that detect distress through multi-modal sensing and autonomously initiate defensive, evidentiary, and emergency-communication actions. A personal safety device is disclosed that autonomously detects and responds to user distress. The device includes a deformable housing acting as an activation interface, a processing core executing a multi-modal threat-detection algorithm, and physiological, inertial, positional, and acoustic sensors. A location module, imaging and illumination units, and self-defence systems—including a controlled non-lethal electric-discharge unit and a forensic marking-fluid dispenser—are activated when a multi-condition threat rule is satisfied. The system computes a dynamic threat index from heart-rate variability, motion deviation, oxygen-saturation change, electrodermal activity, and distress-signature analysis, and transmits diagnostic and positional information to designated recipients. A cloud-based behavioural-learning platform updates user-specific thresholds to enhance detection accuracy without requiring deliberate user action.

There is described a method for identifying potential personal safety incidents of an individual (5), the method comprising the steps of receiving a sample data set comprising motion data and vital sign data from one or more sensors (14, 16, 18) associated with the individual, determining one or more motion features and one or more vital sign features, and determining whether the sample data set is indicative of a potential personal safety incident of the individual based on a model and at least one of the motion and vital sign features. The sensors can be provided by a fitness tracker and / or an activity tracker, such as a smartphone and / or a smart watch. The method can also include determining one or more responses such as alerting another party of the potential personal safety incident or triggering a deterrent mechanism.

In a linked notification system configured by communication-connecting at least one external device to a portable notification device, on receipt of a state signal indicating a state of the external device from the external device, the portable notification device refers to the notification control information in which a notification destination is associated with a notification condition defined by using a state of the external device, and determines whether the notification condition is satisfied or not on the basis of the state signal. When it is determined that the notification condition is satisfied, the portable notification device notifies the notification destination associated with the notification condition.
