SmartBox – From Lost Items to Daily Habits
People often forget to return daily essentials, like wallets, phones, or jewelry. Not because they lose them but because they never build the habit. Most existing solutions focus on tracking lost items, not preventing the loss.
I reframed the problem as a behavior gap, not a location gap. SmartBox uses timely reminders, visual feedback, and physical cues to help users form daily return habits.

Finding the real problem is harder
Early on, I assumed the challenge was “how to help people find lost items.”
But through behavioral analysis and 5 Whys, I realized the real issue was why people forget to put things away in the first place.
Solving the right problem made the entire product more focused, meaningful, and user-centered.

Theory guides, but testing proves
Understanding concepts like habit formation, timing, and cognitive load helped me shape the foundation of the product.
But what truly brought the design to life was testing it, watching users interact with the wireframes revealed what worked, what didn’t, and how to make behavior feel intuitive.
This project taught me that translating theory into effective design doesn’t happen on paper, it happens in front of users.
