Safety Bell Connecting residents with help in an emergency
Safety Bell helps people who live or work alone in Gyeonggi Province, South Korea, alert authorities in an emergency. It provides an additional way to report incidents for residents and shop owners who may be vulnerable to crime or accidents.
Working with Gyeonggi Province, I designed the service flow and interfaces across a connected device, a mobile app, and a desktop reporting console.
From a button press to an emergency alert
Working with the police and Gyeonggi Province, we designed a reporting flow for rapid response. Pressing the device’s button sends a signal to the registered phone, which forwards the user’s saved reporting details to the police and provincial control center.
Confirm a report or cancel an accidental alert
After the button is pressed, a push notification lets the user check the report’s status in the app. If it was pressed by accident, they can quickly cancel the alert to avoid an unnecessary response.
Keep the device connected and up to date
The device communicates with the app over Bluetooth Low Energy. Users can register their device, set up its network connection, and install firmware updates from the app.
Give responders a live view of incoming reports
Both the police and the provincial control center receive emergency reports. The monitoring interface shows each report’s location and details in real time to support a prompt response.
Turn service data into a useful overview
The admin dashboard brings service usage and reporting data into one view. I chose visualizations suited to each dataset to help operators identify patterns and opportunities to improve the service.
Support day-to-day user management
Operators can search, review, update, delete, and export registered user records from the admin interface, helping them handle inquiries and routine service operations.
Designing with public-sector stakeholders
The project required working within defined functional requirements while addressing GS certification and web accessibility requirements.
I coordinated stakeholders with different priorities, balancing their needs with the project’s business constraints. The experience strengthened my ability to manage the project and work through issues across organizations.
