A Light That Teaches

Bulby was born during a 2-week innovation challenge organized by Adeo, where multidisciplinary student teams were invited to imagine the smart home of tomorrow. I joined a diverse group composed of developers from 42, business & marketing students from HEC, and 3D designers from Condé. My role: design the UX and UI of the product experience, from first interaction to final feedback.

Together, we built Bulby — a connected light that helps kids learn daily routines and soft skills through positive feedback. More than just a device, Bulby is a small presence in the home that reacts, encourages, and teaches — without screens.

Define Problems

Design Solutions

We designed Bulby around voice, light, and presence. The device glows subtly to reflect emotions (calm, proud, tired), speaks with a friendly tone, and reacts to actions like brushing teeth or completing a task — all tracked via a simple parent app. Parents can define rules, monitor progress, and personalize messages.

Instead of relying on gamification, we focused on emotional design: soft praise, ambient feedback, and gentle encouragement. I worked on the user flows, UI components, and created high-fidelity prototypes tested with real families.

Learnings

Bulby taught me that emotion is a design tool — and trust isn’t built through flashy features, but through consistency and tone. Working with people from different backgrounds also reminded me of the power of co-creation: business constraints, tech limits, and creative ideas all met in the same room.

Most importantly, I learned that even the simplest objects can become magical when designed with care, purpose, and empathy.
