User interviews
Through Mi-Fi prototype verification, I validated usability, gathered feedback on key interactions, and identified whether the design aligned with users’ needs, expectations, and behaviors.
Card sorting
I used card sorting to understand how users naturally categorize information and what cognitive model they apply when using the app.
The insights helped shape the app’s information architecture and navigation structure to better match users’ mental models and improve discoverability.
