Safety GPS Watch
This project introduces a wearable GPS safety watch paired with a mobile interface. Instead of relying only on a phone screen, the system provides real-time feedback about the safety level of a location through both digital and physical signals.
The target users are individuals who move through urban spaces at night, particularly those living near or traveling through potentially unsafe areas.
Recent incidents involving students walking alone at night raised an important question: how can we make safety awareness more immediate and intuitive?
This project responds to that concern by combining GPS tracking with real-time risk visualization. The system allows users to see the safety level of their surroundings and react accordingly. If the GPS signal is interrupted or the user remains stationary, the app holds the last known position to avoid sudden data jumps.
An integrated emergency button provides an additional layer of protection, allowing users to quickly reach help when necessary.
