What I Learned
What I Learned
Designing Lumi showed me how emotions translate into interactions design. Quick feedback sessions revealed that users felt more connected through Shima’s playful reactions than through long chat-like exchanges. The insight was clear: simplicity is not about cutting features, but about removing friction so gestures feel effortless. I also learned that accessibility isn’t optional - people of different ages and tech levels need clarity and intuitive flows to feel included

Next Steps
Next Steps
The next phase is to prototype animations that amplify Shima’s emotional responses and to add subtle button feedback for warmth. Accessibility wil be extended with full screen reader support. Finally, I plan cross-platform testing on iOS and Android, followed by structured usability sessions to validate whether Lumi consistently delivers it’s emotional goal.

Closing thoughts
Closing thoughts
Lumi became more than a prototype - it turned into a daily ritual of closeness. Testing confirmed that even minimal gestures, when designed with empathy, can make distance feel smaller. For me, this project was both a UX lesson in clarity and a personal reflection on staying connected to loved ones.
