Case 02 of 18 · The Crash-Test Family
Bolas range test
How far can the skeleton move, and can a filmed person be measured the same way?
54 motions that push one skeleton to the end of every joint's range, scored like a fitness assessment, plus a Video → Bolas tool that turns a clip of any person into the same skeleton and the same report.
How it was made
- Write one motion per joint limit, grouped A to E by body region.
- Score each motion the way a physiotherapist scores a range-of-motion test.
- Run MoveNet on a video, map its keypoints onto the Bolas skeleton, and print the same report.
What this case teaches
- Know the limits of the body before asking it to act. An acted scene that breaks a joint limit reads as wrong even when nobody can say why.
- One report for a drawn figure and a filmed person makes the two directly comparable.
- Video becomes a source of motion data, which the hybrid cases later depend on.
How it differs. The pencil test checked a beat against a text. This case checks a body against its own limits.
