React probe clips

Every clip here is an animation of the published test set — the same poses, held hand, context frame and calibration you download from test_sets/probes_v1. Rendered from that package, not from a second sampling run, so a clip cannot drift from the data it illustrates. Static overlays and the method are on the test set page.

Each tile shows the first frame; tap or click to load and play. 72 videos preloading at once is what a phone chokes on.

The background is frozen on purpose. The camera image at step k is unknown — that is the whole point of a probe — so animating anything but the sensors would be inventing pixels. What moves is the only thing known: where the sensor would be. The dimmed hand is the one that must stay still; the circles are the 0.12 m exclusion zones.

Start frames come from held-out intervals of splits.json, never training frames. Eligible: 2026-05-10, 2026-05-11, 2026-05-19; this draw selected 2026-05-10, 2026-05-11 (2026-05-19 was not sampled this time — chance, not a judgement).
