What This Is
A health monitoring platform that connects HealthyPi hardware (HealthyPi 6 Pi HAT and HealthyPi Move wearable) to an analysis engine, virtual patient simulator, and agentic intelligence layer. It processes ECG, PPG, EDA, IMU, and EEG signals for HRV analysis, stress scoring, and sleep quality assessment — with a virtual patient simulator for hardware-free development.
Key Features
- Multimodal Biometric Processing: ECG/PPG heart rate and HRV (SDNN, RMSSD, LF/HF), EDA stress scoring, IMU activity classification, EEG meditation scoring
- Analysis Engine: HRV time-domain and frequency-domain calculations, stress level scoring (EDA + HRV fusion), sleep quality scoring, baseline learning with deviation detection
- Virtual Patient Simulator: Synthetic waveform generation via NeuroKit2 with scriptable scenarios (resting, stress response, deep sleep) — mock interface indistinguishable from real hardware at the NATS level
- Agentic Integration: Registered with the multi-agent orchestrator for autonomous health queries, capability-based authorization with Ed25519 tokens
- Desktop & Mobile Interfaces: macOS menu bar app with real-time health status, iOS/WatchOS prototype with HealthKit sync
