Danger Detection Using Existing Sensors Without Dedicated Hardware

Instead of warning the disadvantaged person directly through a portable terminal they carry, the system inverts the approach by detecting the person's approach to dangerous locations using sensors and then notifying guardians or caregivers through their terminals. This reversal ensures the warning reaches someone who can act on it, even if the disadvantaged person cannot recognize or respond to the warning themselves.

The system introduces an intermediary mechanism where sensors detect the disadvantaged person's location and the system acts as a mediator to transmit danger warnings to guardians. This intermediary approach bypasses the need for the disadvantaged person to directly receive or understand the warning, solving the reliability issue when they cannot recognize alerts.

The system uses existing multi-functional devices (smartphones, tablets, or computers with cameras and sensors) that can serve multiple purposes including danger detection, rather than requiring dedicated single-function sensors. This universal approach reduces device complexity and eliminates the need for separate dedicated sensor installations on verandas or other dangerous locations.

The system leverages the self-service capability of existing sensor-incorporating apparatuses (devices with built-in sensors like cameras, accelerometers, and GPS) to detect danger. These devices already possess the necessary sensing capabilities for their primary functions, and the system repurposes them for danger detection without requiring additional dedicated sensors or installations.
