A compact gesture recorder turns the latest pointer path into a simplified directional command, measuring distance, corners and confidence in real time.
- Product moments
- Spatial storytelling
- Interactive identity systems
- Distance-based simplification produces clean connected joints
- Direction, corner count and confidence derive from the same path
- No pointer capture is required for the preview to remain usable
- A component-specific renderer and control contract—not a palette swap of another release
- Compact and full previews share one visibility-aware production renderer
Adaptive sampling, capped DPR and visibility-based suspension keep the renderer predictable. Test density on low-power mobile hardware before increasing it.
Pointer and touch coordinates are container-scoped; offscreen renderers stop work and pixel ratio is capped.
The visual canvas is decorative by default. Pair it with a semantic heading or description, and reduced motion holds a stable rendered frame.
BEHAVIOR
Built to move without taking over.
