From 7c1351fd5d56e4657b638df65f29cc48b4467182 Mon Sep 17 00:00:00 2001 From: rUv Date: Thu, 12 Mar 2026 20:59:57 -0400 Subject: [PATCH] feat(demo): wire all 6 RuVector WASM attention mechanisms into pose fusion MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: dual-modal WASM browser pose estimation demo (ADR-058) Live webcam video + WiFi CSI fusion for real-time pose estimation. Two parallel CNN pipelines (ruvector-cnn-wasm) with attention-weighted fusion and dynamic confidence gating. Three modes: Dual, Video-only, CSI-only. Includes pre-built WASM package (~52KB) for browser deployment. - ADR-058: Dual-modal architecture design - ui/pose-fusion.html: Main demo page with dark theme UI - 7 JS modules: video-capture, csi-simulator, cnn-embedder, fusion-engine, pose-decoder, canvas-renderer, main orchestrator - Pre-built ruvector-cnn-wasm WASM package for browser - CSI heatmap, embedding space visualization, latency metrics - WebSocket support for live ESP32 CSI data - Navigation link added to main dashboard Co-Authored-By: claude-flow * fix: motion-responsive skeleton + through-wall CSI tracking - Pose decoder now uses per-cell motion grid to track actual arm/head positions — raising arms moves the skeleton's arms, head follows lateral movement - Motion grid (10x8 cells) tracks intensity per body zone: head, left/right arm upper/mid, legs - Through-wall mode: when person exits frame, CSI maintains presence with slow decay (~10s) and skeleton drifts in exit direction - CSI simulator persists sensing after video loss, ghost pose renders with decreasing confidence - Reduced temporal smoothing (0.45) for faster response to movement Co-Authored-By: claude-flow * fix: video fills available space + correct WASM path resolution - Remove fixed aspect-ratio and max-height from video panel so it fills the available viewport space without scrolling - Grid uses 1fr row for content area, overflow:hidden on main grid - Fix WASM path: resolve relative to JS module file using import.meta.url instead of hardcoded ./pkg/ which resolved incorrectly on gh-pages - Responsive: mobile still gets aspect-ratio constraint Co-Authored-By: claude-flow * feat: live ESP32 CSI pipeline + auto-connect WebSocket - Add auto-connect to local sensing server WebSocket (ws://localhost:8765) - Demo shows "Live ESP32" when connected to real CSI data - Add build_firmware.ps1 for native Windows ESP-IDF builds (no Docker) - Add read_serial.ps1 for ESP32 serial monitor Pipeline: ESP32 → UDP:5005 → sensing-server → WS:8765 → browser demo Co-Authored-By: claude-flow * docs: add ADR-059 live ESP32 CSI pipeline + update README with demo links - ADR-059: Documents end-to-end ESP32 → sensing server → browser pipeline - README: Add dual-modal pose fusion demo link, update ADR count to 49 - References issue #245 Co-Authored-By: claude-flow * feat: RSSI visualization, RuVector attention WASM, cache-bust fixes - Add animated RSSI Signal Strength panel with sparkline history - Fix RuVector WasmMultiHeadAttention retptr calling convention - Wire up RuVector Multi-Head + Flash Attention in CNN embedder - Add ambient temporal drift to CSI simulator for visible heatmap animation - Fix embedding space projection (sparse projection replaces cancelling sum) - Add auto-scaling to embedding space renderer - Add cache busters (?v=4) to all ES module imports to prevent stale caches - Add diagnostic logging for module version verification - Add RSSI tracking with quality labels and color-coded dBm display - Includes ruvector-attention-wasm v2.0.5 browser ESM wrapper Co-Authored-By: claude-flow * feat: 26-keypoint dexterous pose + full RuVector attention pipeline Pose Decoder (17 → 26 keypoints): - Add finger approximations: thumb, index, pinky per hand (6 new) - Add toe tips: left/right foot index (2 new) - Add neck keypoint (1 new) - Hand openness driven by arm motion intensity - Finger positions computed from wrist-elbow axis angles CNN Embedder (full RuVector WASM pipeline): - Stage 1: Multi-Head Attention (global spatial reasoning) - Stage 2: Hyperbolic Attention (hierarchical body-part tree) - Stage 3: MoE Attention (3 experts: upper/lower/extremities, top-2) - Blended 40/30/30 weighting → final embedding projection Canvas Renderer: - Magenta finger joints with distinct glow - Cyan toe tips - White neck keypoint - Thinner limb lines for hand/foot connections - Joint count shown in overlay label CSI Simulator: - Skip synthetic person state when live ESP32 connected - Only simulate CSI data in demo mode (was already correct) Embedding Space: - Fixed projection: sparse 8-dim projection replaces cancelling sum - Auto-scaling normalizes point spread to fill canvas Cache busters bumped to v=5 on all imports. Co-Authored-By: claude-flow * fix: centroid-based pose tracking for responsive limb movement Rewrites pose decoder from intensity-based to position-based tracking: - Arms now track toward motion centroid in each body zone - Elbow/wrist positions computed along shoulder→centroid vector - Legs track toward lower-body zone centroids - Smoothing reduced from 0.45 to 0.25 for responsiveness - Zone centroids blend 30% old / 70% new each frame 6 body zones with overlapping coverage: - Head (top 20%, center cols) - Left/Right Arm (rows 10-60%, outer cols) - Torso (rows 15-55%, center cols) - Left/Right Leg (rows 50-100%, half cols each) Hand openness now driven by arm spread distance + raise amount. Cache busters v=6. Co-Authored-By: claude-flow * fix: remove duplicate lAnkleX/rAnkleX declarations in pose-decoder Stale code block from old intensity-based tracking was left behind, re-declaring variables already defined by centroid-based tracking. Co-Authored-By: claude-flow * feat(demo): wire all 6 RuVector WASM attention mechanisms into pose fusion - Add WasmLinearAttention and WasmLocalGlobalAttention to browser ESM wrapper - Add 6 WASM utility functions (batch_normalize, pairwise_distances, etc.) - Extend CnnEmbedder to 6-stage pipeline: Flash → MHA → Hyperbolic → Linear → MoE → L+G - Use log-energy softmax blending across all 6 stages - Wire WASM cosine_similarity and normalize into FusionEngine - Add RuVector pipeline stats panel to UI (energy, refinement, pose impact) - Compute embedding-to-joint mapping stats without modifying joint positions - Center camera prompt with flexbox layout - Add cache busters v=12 Co-Authored-By: claude-flow --- README.md | 6 +- ...-058-ruvector-wasm-browser-pose-example.md | 392 +++++ docs/adr/ADR-059-live-esp32-csi-pipeline.md | 83 + firmware/esp32-csi-node/build_firmware.ps1 | 31 + firmware/esp32-csi-node/read_serial.ps1 | 14 + ui/index.html | 1 + ui/pose-fusion.html | 201 +++ ui/pose-fusion/build.sh | 30 + ui/pose-fusion/css/style.css | 535 +++++++ ui/pose-fusion/js/canvas-renderer.js | 307 ++++ ui/pose-fusion/js/cnn-embedder.js | 443 ++++++ ui/pose-fusion/js/csi-simulator.js | 357 +++++ ui/pose-fusion/js/fusion-engine.js | 183 +++ ui/pose-fusion/js/main.js | 472 ++++++ ui/pose-fusion/js/pose-decoder.js | 553 +++++++ ui/pose-fusion/js/video-capture.js | 235 +++ ui/pose-fusion/pkg/ruvector-attention/LICENSE | 21 + .../pkg/ruvector-attention/README.md | 220 +++ .../pkg/ruvector-attention/package.json | 28 + .../ruvector_attention_browser.js | 642 ++++++++ .../ruvector_attention_wasm.d.ts | 359 +++++ .../ruvector_attention_wasm.js | 1417 +++++++++++++++++ .../ruvector_attention_wasm_bg.wasm | Bin 0 -> 154533 bytes .../ruvector_attention_wasm_bg.wasm.d.ts | 71 + .../pkg/ruvector_cnn_wasm/package.json | 26 + .../ruvector_cnn_wasm/ruvector_cnn_wasm.js | 802 ++++++++++ .../ruvector_cnn_wasm_bg.wasm | Bin 0 -> 51748 bytes 27 files changed, 7428 insertions(+), 1 deletion(-) create mode 100644 docs/adr/ADR-058-ruvector-wasm-browser-pose-example.md create mode 100644 docs/adr/ADR-059-live-esp32-csi-pipeline.md create mode 100644 firmware/esp32-csi-node/build_firmware.ps1 create mode 100644 firmware/esp32-csi-node/read_serial.ps1 create mode 100644 ui/pose-fusion.html create mode 100644 ui/pose-fusion/build.sh create mode 100644 ui/pose-fusion/css/style.css create mode 100644 ui/pose-fusion/js/canvas-renderer.js create mode 100644 ui/pose-fusion/js/cnn-embedder.js create mode 100644 ui/pose-fusion/js/csi-simulator.js create mode 100644 ui/pose-fusion/js/fusion-engine.js create mode 100644 ui/pose-fusion/js/main.js create mode 100644 ui/pose-fusion/js/pose-decoder.js create mode 100644 ui/pose-fusion/js/video-capture.js create mode 100644 ui/pose-fusion/pkg/ruvector-attention/LICENSE create mode 100644 ui/pose-fusion/pkg/ruvector-attention/README.md create mode 100644 ui/pose-fusion/pkg/ruvector-attention/package.json create mode 100644 ui/pose-fusion/pkg/ruvector-attention/ruvector_attention_browser.js create mode 100644 ui/pose-fusion/pkg/ruvector-attention/ruvector_attention_wasm.d.ts create mode 100644 ui/pose-fusion/pkg/ruvector-attention/ruvector_attention_wasm.js create mode 100644 ui/pose-fusion/pkg/ruvector-attention/ruvector_attention_wasm_bg.wasm create mode 100644 ui/pose-fusion/pkg/ruvector-attention/ruvector_attention_wasm_bg.wasm.d.ts create mode 100644 ui/pose-fusion/pkg/ruvector_cnn_wasm/package.json create mode 100644 ui/pose-fusion/pkg/ruvector_cnn_wasm/ruvector_cnn_wasm.js create mode 100644 ui/pose-fusion/pkg/ruvector_cnn_wasm/ruvector_cnn_wasm_bg.wasm diff --git a/README.md b/README.md index 6f05b5c0..59d202a3 100644 --- a/README.md +++ b/README.md @@ -75,7 +75,7 @@ docker run -p 3000:3000 ruvnet/wifi-densepose:latest |----------|-------------| | [User Guide](docs/user-guide.md) | Step-by-step guide: installation, first run, API usage, hardware setup, training | | [Build Guide](docs/build-guide.md) | Building from source (Rust and Python) | -| [Architecture Decisions](docs/adr/README.md) | 48 ADRs — why each technical choice was made, organized by domain (hardware, signal processing, ML, platform, infrastructure) | +| [Architecture Decisions](docs/adr/README.md) | 49 ADRs — why each technical choice was made, organized by domain (hardware, signal processing, ML, platform, infrastructure) | | [Domain Models](docs/ddd/README.md) | 7 DDD models (RuvSense, Signal Processing, Training Pipeline, Hardware Platform, Sensing Server, WiFi-Mat, CHCI) — bounded contexts, aggregates, domain events, and ubiquitous language | | [Desktop App](rust-port/wifi-densepose-rs/crates/wifi-densepose-desktop/README.md) | **WIP** — Tauri v2 desktop app for node management, OTA updates, WASM deployment, and mesh visualization | @@ -89,8 +89,12 @@ docker run -p 3000:3000 ruvnet/wifi-densepose:latest Real-time pose skeleton from WiFi CSI signals — no cameras, no wearables
