Le Petit Care: A Child-Attuned Design for Personalized ADHD Symptom Management Through AI-powered Extended Reality

Key Visuals

Background / Problem

Le Petit Care addresses limitations of medication-only intervention by supporting ADHD symptom management through immersive and personalized care. The project focuses on reducing stigma and negative self-identity during diagnosis and treatment, while improving accessibility and engagement for children.

My Role

I contributed to HCI/UX research and service design strategy, including interview insight synthesis, child-centered interaction design, and narrative-based therapeutic flow planning for the XR experience.

Process / Method

The team used a mixed-method process: expert interviews (child studies, psychiatry, digital healthcare), interdisciplinary literature review, and iterative prototyping in Unity+C#. We designed a storytelling framework inspired by The Little Prince, where children complete immersive missions while the system captures multimodal signals (voice, head/hand/eye movement). Based on DSM-5 aligned criteria and ADHD-RS-informed features, AI screening supports tailored behavioral training across attention, working memory, executive function, impulse control, behavioral regulation, and emotional regulation.

Result / Outcome

Selected as ACM CHI 2025 Student Design Competition Finalist (CHI EA '25, Yokohama). Preliminary user study validated immersion potential and revealed clear UX improvements for dialogue length, mission clarity, and interaction affordances.
