- **Not a "pose estimation" demo**: This module honestly cannot do what the project name implies
|

- **Lower credibility ceiling**: RSSI sensing is well-known; less impressive than CSI
|

### Implementation Status
|
||||
|
||||
The full commodity sensing pipeline is implemented in `v1/src/sensing/`:
|
||||
|
||||
| Module | File | Description |
|
||||
|--------|------|-------------|
|
||||
| RSSI Collector | `rssi_collector.py` | `LinuxWifiCollector` (live hardware) + `SimulatedCollector` (deterministic testing) with ring buffer |
|
||||
| Feature Extractor | `feature_extractor.py` | `RssiFeatureExtractor` with Hann-windowed FFT, band power (breathing 0.1-0.5 Hz, motion 0.5-3 Hz), CUSUM change-point detection |
|
||||
| Classifier | `classifier.py` | `PresenceClassifier` with ABSENT/PRESENT_STILL/ACTIVE levels, confidence scoring |
|
||||
| Backend | `backend.py` | `CommodityBackend` wiring collector → extractor → classifier, reports PRESENCE + MOTION capabilities |
|
||||
|
||||
**Test coverage**: 36 tests in `v1/tests/unit/test_sensing.py` — all passing:
|
||||
- `TestRingBuffer` (4), `TestSimulatedCollector` (5), `TestFeatureExtractor` (8), `TestCusum` (4), `TestPresenceClassifier` (7), `TestCommodityBackend` (6), `TestBandPower` (2)
|
||||
|
||||
**Dependencies**: `numpy`, `scipy` (for FFT and spectral analysis)
|
||||
|
||||
**Note**: `LinuxWifiCollector` requires a connected Linux WiFi interface (`/proc/net/wireless` or `iw`). On Windows or disconnected interfaces, use `SimulatedCollector` for development and testing.

# ADR-019: Sensing-Only UI Mode with Gaussian Splat Visualization
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Status** | Accepted |
|
||||
| **Date** | 2026-02-28 |
|
||||
| **Deciders** | ruv |
|
||||
| **Relates to** | ADR-013 (Feature-Level Sensing), ADR-018 (ESP32 Dev Implementation) |
|
||||
|
||||
## Context
|
||||
|
||||
The WiFi-DensePose UI was originally built to require the full FastAPI DensePose backend (`localhost:8000`) for all functionality. This backend depends on heavy Python packages (PyTorch ~2GB, torchvision, OpenCV, SQLAlchemy, Redis) making it impractical for lightweight sensing-only deployments where the user simply wants to visualize live WiFi signal data from ESP32 CSI or Windows RSSI collectors.
|
||||
|
||||
A Rust port exists (`rust-port/wifi-densepose-rs`) using Axum with lighter runtime footprint (~10MB binary, ~5MB RAM), but it still requires libtorch C++ bindings and OpenBLAS for compilation—a non-trivial build.
|
||||
|
||||
Users need a way to run the UI with **only the sensing pipeline** active, without installing the full DensePose backend stack.
|
||||
|
||||
## Decision
|
||||
|
||||
Implement a **sensing-only UI mode** that:
|
||||
|
||||
1. **Decouples the sensing pipeline** from the DensePose API backend. The sensing WebSocket server (`ws_server.py` on port 8765) operates independently of the FastAPI backend (port 8000).
|
||||
|
||||
2. **Auto-detects sensing-only mode** at startup. When the DensePose backend is unreachable, the UI sets `backendDetector.sensingOnlyMode = true` and:
|
||||
- Suppresses all API requests to `localhost:8000` at the `ApiService.request()` level
|
||||
- Skips initialization of DensePose-dependent tabs (Dashboard, Hardware, Live Demo)
|
||||
- Shows a green "Sensing mode" status toast instead of error banners
|
||||
- Silences health monitoring polls
|
||||
|
||||
3. **Adds a new "Sensing" tab** with Three.js Gaussian splat visualization:
|
||||
- Custom GLSL `ShaderMaterial` rendering point-cloud splats on a 20×20 floor grid
|
||||
- Signal field splats colored by intensity (blue → green → red)
|
||||
- Body disruption blob at estimated motion position
|
||||
- Breathing ring modulation when breathing-band power detected
|
||||
- Side panel with RSSI sparkline, feature meters, and classification badge
|
||||
|
||||
4. **Python WebSocket bridge** (`v1/src/sensing/ws_server.py`) that:
|
||||
- Auto-detects ESP32 UDP CSI stream on port 5005 (ADR-018 binary frames)
|
||||
- Falls back to `WindowsWifiCollector` → `SimulatedCollector`
|
||||
- Runs `RssiFeatureExtractor` → `PresenceClassifier` pipeline
|
||||
- Broadcasts JSON sensing updates every 500ms on `ws://localhost:8765`
|
||||
|
||||
5. **Client-side fallback**: `sensing.service.js` generates simulated data when the WebSocket server is unreachable, so the visualization always works.
|
||||

||||

## Files
|
||||
|
||||
### Created
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `v1/src/sensing/ws_server.py` | Python asyncio WebSocket server with auto-detect collectors |
|
||||
| `ui/components/SensingTab.js` | Sensing tab UI with Three.js integration |
|
||||
| `ui/components/gaussian-splats.js` | Custom GLSL Gaussian splat renderer |
|
||||
| `ui/services/sensing.service.js` | WebSocket client with reconnect + simulation fallback |
|
||||
|
||||
### Modified
|
||||
| File | Change |
|
||||
|------|--------|
|
||||
| `ui/index.html` | Added Sensing nav tab button and content section |
|
||||
| `ui/app.js` | Sensing-only mode detection, conditional tab init |
|
||||
| `ui/style.css` | Sensing tab layout and component styles |
|
||||
| `ui/config/api.config.js` | `AUTO_DETECT: false` (sensing uses own WS) |
|
||||
| `ui/services/api.service.js` | Short-circuit requests in sensing-only mode |
|
||||
| `ui/services/health.service.js` | Skip polling when backend unreachable |
|
||||
| `ui/components/DashboardTab.js` | Graceful failure in sensing-only mode |
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
- UI works with zero heavy dependencies—only `pip install websockets` (+ numpy/scipy already installed)
|
||||
- ESP32 CSI data flows end-to-end without PyTorch, OpenCV, or database
|
||||
- Existing DensePose tabs still work when the full backend is running
|
||||
- Clean console output—no `ERR_CONNECTION_REFUSED` spam in sensing-only mode
|
||||
|
||||
### Negative
|
||||
- Two separate WebSocket endpoints: `:8765` (sensing) and `:8000/api/v1/stream/pose` (DensePose)
|
||||
- Pose estimation, zone occupancy, and historical data features unavailable in sensing-only mode
|
||||
- Client-side simulation fallback may mislead users if they don't notice the "Simulated" badge
|
||||
|
||||
### Neutral
|
||||
- Rust Axum backend remains a future option for a unified lightweight server
|
||||
- The sensing pipeline reuses the existing `RssiFeatureExtractor` and `PresenceClassifier` classes unchanged
|
||||
|
||||
## Alternatives Considered
|
||||
|
||||
1. **Install minimal FastAPI** (`pip install fastapi uvicorn pydantic`): Starts the server but pose endpoints return errors without PyTorch.
|
||||
2. **Build Rust backend**: Single binary, but requires libtorch + OpenBLAS build toolchain.
|
||||
3. **Merge sensing into FastAPI**: Would require FastAPI installed even for sensing-only use.
|
||||
|
||||
Option 1 was rejected because it still shows broken tabs. The chosen approach cleanly separates concerns.

# ADR-020: Migrate AI/Model Inference to Rust with RuVector and ONNX Runtime
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Status** | Accepted |
|
||||
| **Date** | 2026-02-28 |
|
||||
| **Deciders** | ruv |
|
||||
| **Relates to** | ADR-016 (RuVector Integration), ADR-017 (RuVector-Signal-MAT), ADR-019 (Sensing-Only UI) |
|
||||
|
||||
## Context
|
||||
|
||||
The current Python DensePose backend requires ~2GB+ of dependencies:
|
||||
|
||||
| Python Dependency | Size | Purpose |
|
||||
|-------------------|------|---------|
|
||||
| PyTorch | ~2.0 GB | Neural network inference |
|
||||
| torchvision | ~500 MB | Model loading, transforms |
|
||||
| OpenCV | ~100 MB | Image processing |
|
||||
| SQLAlchemy + asyncpg | ~20 MB | Database |
|
||||
| scikit-learn | ~50 MB | Classification |
|
||||
| **Total** | **~2.7 GB** | |
|
||||
|
||||
This makes the DensePose backend impractical for edge deployments, CI pipelines, and developer laptops where users only need WiFi sensing + pose estimation.
|
||||
|
||||
Meanwhile, the Rust port at `rust-port/wifi-densepose-rs/` already has:
|
||||
|
||||
- **12 workspace crates** covering core, signal, nn, api, db, config, hardware, wasm, cli, mat, train
|
||||
- **5 RuVector crates** (v2.0.4, published on crates.io) integrated into signal, mat, and train crates
|
||||
- **3 NN backends**: ONNX Runtime (default), tch (PyTorch C++), Candle (pure Rust)
|
||||
- **Axum web framework** with WebSocket support in the MAT crate
|
||||
- **Signal processing pipeline**: CSI processor, BVP, Fresnel geometry, spectrogram, subcarrier selection, motion detection, Hampel filter, phase sanitizer
|
||||
|
||||
## Decision
|
||||
|
||||
Adopt the Rust workspace as the **primary backend** for AI/model inference and signal processing, replacing the Python FastAPI stack for production deployments.
|
||||
|
||||
### Phase 1: ONNX Runtime Default (No libtorch)
|
||||
|
||||
Use the `wifi-densepose-nn` crate with `default-features = ["onnx"]` only. This avoids the libtorch C++ dependency entirely.
|
||||
|
||||
| Component | Rust Crate | Replaces Python |
|
||||
|-----------|-----------|-----------------|
|
||||
| CSI processing | `wifi-densepose-signal::csi_processor` | `v1/src/sensing/feature_extractor.py` |
|
||||
| Motion detection | `wifi-densepose-signal::motion` | `v1/src/sensing/classifier.py` |
|
||||
| BVP extraction | `wifi-densepose-signal::bvp` | N/A (new capability) |
|
||||
| Fresnel geometry | `wifi-densepose-signal::fresnel` | N/A (new capability) |
|
||||
| Subcarrier selection | `wifi-densepose-signal::subcarrier_selection` | N/A (new capability) |
|
||||
| Spectrogram | `wifi-densepose-signal::spectrogram` | N/A (new capability) |
|
||||
| Pose inference | `wifi-densepose-nn::onnx` | PyTorch + torchvision |
|
||||
| DensePose mapping | `wifi-densepose-nn::densepose` | Python DensePose |
|
||||
| REST API | `wifi-densepose-mat::api` (Axum) | FastAPI |
|
||||
| WebSocket stream | `wifi-densepose-mat::api::websocket` | `ws_server.py` |
|
||||
| Survivor detection | `wifi-densepose-mat::detection` | N/A (new capability) |
|
||||
| Vital signs | `wifi-densepose-mat::ml` | N/A (new capability) |
|
||||
|
||||
### Phase 2: RuVector Signal Intelligence
|
||||
|
||||
The 5 RuVector crates provide subpolynomial algorithms already wired into the Rust signal pipeline:
|
||||
|
||||
| Crate | Algorithm | Use in Pipeline |
|
||||
|-------|-----------|-----------------|
|
||||
| `ruvector-mincut` | Subpolynomial min-cut | Dynamic subcarrier partitioning (sensitive vs insensitive) |
|
||||
| `ruvector-attn-mincut` | Attention-gated min-cut | Noise-suppressed spectrogram generation |
|
||||
| `ruvector-attention` | Sensitivity-weighted attention | Body velocity profile extraction |
|
||||
| `ruvector-solver` | Sparse Fresnel solver | TX-body-RX distance estimation |
|
||||
| `ruvector-temporal-tensor` | Compressed temporal buffers | Breathing + heartbeat spectrogram storage |
|
||||
|
||||
These replace the Python `RssiFeatureExtractor` with hardware-aware, subcarrier-level feature extraction.
|
||||
|
||||
### Phase 3: Unified Axum Server
|
||||
|
||||
Replace both the Python FastAPI backend (port 8000) and the Python sensing WebSocket (port 8765) with a single Rust Axum server:
|
||||
|
||||
```
|
||||
ESP32 (UDP :5005) ──▶ Rust Axum server (:8000) ──▶ UI (browser)
|
||||
├── /health/* (health checks)
|
||||
├── /api/v1/pose/* (pose estimation)
|
||||
├── /api/v1/stream/* (WebSocket pose stream)
|
||||
├── /ws/sensing (sensing WebSocket — replaces :8765)
|
||||
└── /ws/mat/stream (MAT domain events)
|
||||
```
|
||||
|
||||
### Build Configuration
|
||||
|
||||
```toml
|
||||
# Lightweight build — no libtorch, no OpenBLAS
|
||||
cargo build --release -p wifi-densepose-mat --no-default-features --features "std,api,onnx"
|
||||
|
||||
# Full build with all backends
|
||||
cargo build --release --features "all-backends"
|
||||
```
|
||||
|
||||
### Dependency Comparison
|
||||
|
||||
| | Python Backend | Rust Backend (ONNX only) |
|
||||
|---|---|---|
|
||||
| Install size | ~2.7 GB | ~50 MB binary |
|
||||
| Runtime memory | ~500 MB | ~20 MB |
|
||||
| Startup time | 3-5s | <100ms |
|
||||
| Dependencies | 30+ pip packages | Single static binary |
|
||||
| GPU support | CUDA via PyTorch | CUDA via ONNX Runtime |
|
||||
| Model format | .pt/.pth (PyTorch) | .onnx (portable) |
|
||||
| Cross-compile | Difficult | `cargo build --target` |
|
||||
| WASM target | No | Yes (`wifi-densepose-wasm`) |
|
||||
|
||||
### Model Conversion
|
||||
|
||||
Export existing PyTorch models to ONNX for the Rust backend:
|
||||
|
||||
```python
|
||||
# One-time conversion (Python)
|
||||
import torch
|
||||
model = torch.load("model.pth")
|
||||
torch.onnx.export(model, dummy_input, "model.onnx", opset_version=17)
|
||||
```
|
||||
|
||||
The `wifi-densepose-nn::onnx` module loads `.onnx` files directly.
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
- Single ~50MB static binary replaces ~2.7GB Python environment
|
||||
- ~20MB runtime memory vs ~500MB
|
||||
- Sub-100ms startup vs 3-5 seconds
|
||||
- Single port serves all endpoints (API, WebSocket sensing, WebSocket pose)
|
||||
- RuVector subpolynomial algorithms run natively (no FFI overhead)
|
||||
- WASM build target enables browser-side inference
|
||||
- Cross-compilation for ARM (Raspberry Pi), ESP32-S3, etc.
|
||||
|
||||
### Negative
|
||||
- ONNX model conversion required (one-time step per model)
|
||||
- Developers need Rust toolchain for backend changes
|
||||
- Python sensing pipeline (`ws_server.py`) remains useful for rapid prototyping
|
||||
- `ndarray-linalg` requires OpenBLAS or system LAPACK for some signal crates
|
||||
|
||||
### Migration Path
|
||||
1. Keep Python `ws_server.py` as fallback for development/prototyping
|
||||
2. Build Rust binary with `cargo build --release -p wifi-densepose-mat`
|
||||
3. UI detects which backend is running and adapts (existing `sensingOnlyMode` logic)
|
||||
4. Deprecate Python backend once Rust API reaches feature parity
|
||||
|
||||
## Verification
|
||||
|
||||
```bash
|
||||
# Build the Rust workspace (ONNX-only, no libtorch)
|
||||
cd rust-port/wifi-densepose-rs
|
||||
cargo check --workspace 2>&1
|
||||
|
||||
# Build release binary
|
||||
cargo build --release -p wifi-densepose-mat --no-default-features --features "std,api"
|
||||
|
||||
# Run tests
|
||||
cargo test --workspace
|
||||
|
||||
# Binary size
|
||||
ls -lh target/release/wifi-densepose-mat
