Try it live Description
A child can know the rule and still find the next transition difficult. I KNOW offers a small 3D classroom where they can rehearse what happens next, one concrete cue at a time. It is a world as a gift for the child who needs a way through the next change.
As an absorbing classroom activity ends, the visitor explores a familiar place, watches an articulated child demonstrate hands here, step back and take a breathing break, and confirms each action before moving on. Replay and sound controls make it easy to repeat the cues. The experience ends with three actions practiced and a way to start again.
The classroom furniture was generated ahead of time with Tripo from reference photographs. React Three Fiber, Drei and Three.js provide the room, the child, the camera and the animation, and ElevenLabs provides the spoken cues.
Before the event, I KNOW existed as a film-led prototype with a known-rule and observed-behavior context, a reasoning flow, a prepared Tripo companion and a Three.js presentation. The Tripothon version adds the focused classroom transition rehearsal: photo-derived Tripo furniture, an explorable classroom and model reveal, the articulated hands, step-back and break movements, spoken cues, replay and sound controls, confirmation for each action, and an earned three-action completion with restart.
This is a focused hackathon prototype, not a claim of clinical effectiveness. The 62-second walkthrough is edited from actual screen captures of the app, with waiting time removed and an extended hold on the genuine completion screen.
How Tripo was used
Tripo makes the real classroom furniture familiar in 3D.
- Classroom furniture: Tripo H3.1, used through Krea, turned classroom reference photographs into textured GLB furniture: a break corner and a shared desk with chairs.
- In the experience: the break corner is explored in the model reveal and reused inside the rehearsal. All assets were generated before playback; the visitor flow does not present loading as live generation.
