ANTES DEL SAQUE

+

+ La mesa completa. +
+ La pelota visible. +

+
    +
  1. + Coloca el teléfono horizontal y fijo en un soporte, elevado + a un costado. +
    2. +
  2. + Marca las esquinas en este orden: cercana izquierda, cercana + derecha, lejana derecha y lejana izquierda. +
    3. +
  3. + Comprueba que la pelota deje una trayectoria. Ajusta color, + sensibilidad y tamaño si es necesario. +
    4. +
  4. + Reanuda y juega. Confirma puntos dudosos o corrige el último + con un toque. +
    5. +
+

+ El modo automático es experimental: solo suma posibles dobles + botes tras un intercambio observado. No arbitra saques, red ni + bordes. En asistido, todos los puntos se confirman. +

+

+ La cámara se procesa aquí, sin subir video. Mantén la página + abierta; al bloquear el teléfono, el partido se pausa. +

+

+ Para instalar: usa «Añadir a pantalla de inicio» en el menú + del navegador. Necesitas conexión para abrir o recargar la + aplicación. El partido abierto sigue funcionando si se corta + la red. +

Experimental automatic mode can accept those proposals, with an explicit accuracy caveat. +- Undo, correct previous point, repeat/let, pause, interrupted matches, rematches and results sharing. +- IndexedDB history, validated JSON import/export, speech announcements, optional Wake Lock and scoped installable PWA with offline fallback page. + +## Camera setup + +Use a fixed, elevated, diagonal side view, enough light, one visible ball, and no moving camera. Select the four corners in order: near-left, near-right, far-right, far-left. Set the player at the near end during match setup. The overlay marks the estimated halfway line; it is a planar guide, not a reconstruction of the physical net or airborne ball. + +After calibration, check the trail and press Reanudar. If the detector follows clothing or reflections, adjust color, sensitivity and expected size. Try better placement before increasing sensitivity. Keep the page visible. The app pauses when hidden; it cannot see play while the screen is locked. + +## Vision implementation and limits + +The implementation uses original, lightweight TypeScript computer vision rather than distributing unverified pretrained weights: two temporal differences, white/orange pixel gating, connected components, projective ROI filtering, motion prediction and candidate ambiguity rejection. A projected plane and image trajectory reversals generate bounce candidates. A broad scene change invalidates calibration; long frame gaps invalidate the track. + +A bright ball against a pale background, rapid blur, occlusion or moving white clothing can defeat this detector. Image reversals do not prove a 3D bounce. Only two compatible reversals on the same side after observed crossings can yield a possible double-bounce winner; the automatic mode is explicitly experimental. Losing the ball alone never determines a winner. A detected rally disappearing can request human confirmation. Legal serve, net lets, edges, unseen hits and all possible outcomes are not fully adjudicated. + +No measured real-game precision or coverage is claimed. The original plan's 98% precision / 80% coverage target is **not validated or achieved by the available tests**. Completing robust, general automatic scoring remains dependent on labelled real footage and device evaluation, potentially a licensed temporal model. This release is a usable scorer with real local visual tracking and limited experimental automation, not a validated autonomous referee. + +Research reference: [TTNet](https://arxiv.org/abs/2004.09927). It describes specialized temporal vision with 120-fps data and desktop GPU timing; those results are not this app's results. No TTNet, BlurBall or OpenTTR code or weights are incorporated. + +## Development + +Use the root website toolchain, Bun 1.3.14+ and compatible Node (CI 22.18.0). `bun install --frozen-lockfile` then `bun run dev`. Build the standalone worker with `bun run build:vision`; `dev` and `build` do this automatically. The worker's generated JS is ignored by lint/format. + +Checks: + +```sh +bun run format:check +bun run lint +bun run typecheck +bun run test +bun run build +bunx playwright install chromium +bun run test:e2e +``` + +Playwright runs desktop and mobile-size Chromium against a production build. For a deployed build, set `PINGPONG_TEST_URL` to the deployment origin. Synthetic camera streams exercise capture, calibration and worker transport; they do not validate physical game accuracy. Unit tests use Node's existing test runner to avoid a second testing framework. + +## PWA and privacy + +`public/pingpong/sw.js` has scope `/pingpong`, permitted by a narrowly scoped response header. It never caches portfolio pages, RSC navigation responses or worker JS. New installations cache only the manifest, icons and fallback page; an offline reload intentionally displays a reconnect message rather than relying on a stale Next build. An already-open match continues without network access. IndexedDB stays local and can be unavailable/evicted in private or restricted browsers; users can export results. + +Heavy camera modules are dynamically loaded only on camera matches. No OpenCV/ONNX binary or model is loaded. Existing portfolio dependencies and deployment are retained. The route declares its own metadata and manifest; Navbar hides itself only under `/pingpong`. + +## Deploy / rollback + +Changes to the production branch use the existing Vercel Git integration. Verify CI and the Vercel deployment status, then verify `/pingpong`, worker MIME, manifest, icons and `Service-Worker-Allowed`. Revert the integration commit and redeploy for rollback. `vercel.json` explicitly builds the vision worker before Next. Changing the PWA shell requires bumping its cache version and avoiding immediate activation in an active match. diff --git a/docs/pingpong/validation-report.md b/docs/pingpong/validation-report.md new file mode 100644 index 0000000..4d4f8c1 --- /dev/null +++ b/docs/pingpong/validation-report.md @@ -0,0 +1,30 @@ +# Validation report — 2026-10-10 + +## Status + +Local production validation passed: + +- Formatting and ESLint: passed. +- TypeScript and production build: passed. +- Node tests: 18 passed (16 PingPong + 2 existing portfolio tests). +- Playwright: 14 passed across desktop and mobile-size Chromium, including real worker transport and synthetic automatic proposal/correction. +- Visual inspection: desktop landing and mobile landing/scoreboard screenshots; no horizontal overflow in viewport checks. + +Deployment SHA and production status are recorded in the GitHub PR/deployment history.
