Low-fidelity prototypes
User feedback
The concept was evaluated through scenario-based interviews with hikers aged 20–30, focusing on safety, usability, and design preferences.
Participants valued check-ins, simple alerts, GPS, and comfortable, customizable design. They preferred alerts to reach trusted contacts, not authorities and remove the tag.
Design Iteration
Combined sender/receiver into one bracelet, simplified alerts, replaced screen with SMS GPS, and added a warning mode for better usability.
