VENTURE / 부카루 · Bookaroo
An interactive storybook designed around hand-gesture rehabilitation activities and attention. I focused on comfortable participation for children and understandable results for caregivers.
Received one round of angel funding
01 / CONTEXT
This project was planned around rehabilitation exercises conducted by clinicians in hospitals. The primary users were children aged approximately 5–8 with brain lesions, participating through hand-gesture recognition rather than touch. The priorities were helping children attempt movements comfortably, attend to the activity and make their results understandable to caregivers.
02 / DESIGN DECISIONS
Actual feedback led me to prioritize small movements and repetition. I used that direction to shape hand movements into story missions and designed screens inviting children to participate.
I wanted the story to provide a reason to repeat small movements. This was a design direction informed by feedback, not a measured rehabilitation or attention outcome.
I designed story and play screens alongside a view of activity medals and progress.
The design addresses both children’s participation and caregivers’ need to understand the results. Medals represent activity progress.

Illustrated covers and colored tabs introduce the available activities.
Story scenes and voice missions show different ways to participate.

04 / OUTCOME & REFLECTION
I planned the service and hand-gesture activities for a hospital rehabilitation context and created story, play and progress screens and a prototype. I participated as co-founder for about six months. The venture received one round of angel funding and later concluded due to team operational circumstances. This case presents the design and prototype, without claiming measured rehabilitation or attention gains.
If I revisited the design, I would structure each activity as one story goal, a brief movement cue, an attempt, feedback, then a next activity or a break. I would distinguish between no attempt and a recognition failure, and check whether children can resume after resting.
