// 02 — CHALLENGE
WHY IT MATTERED

The core problem was not just recognizing movement or estimating location in isolation, but combining both into a monitoring system that could interpret context.

For an elderly-care setting, the valuable signal came from knowing what a person was doing, where they were, and whether that combination implied risk.

// 03 — APPROACH
HOW I BUILT IT

I built the HAR component around sequential accelerometer data, benchmarking ANN, CNN, LSTM, and CNN-LSTM models before selecting the strongest performer for real-time inference.

I paired that with an IPS pipeline based on BLE RSSI fingerprinting and supervised baselines, then integrated both outputs into one monitoring flow so location and activity could jointly drive caregiver-facing events.

KEY TAKEAWAYS
  • Benchmarked deep learning models for human activity recognition and classical supervised models for indoor positioning
  • Reached 98.95% HAR F1-score with CNN-LSTM and 84.12% IPS F1-score with Random Forest
  • Used ESP32 receivers and BLE RSSI fingerprinting to add spatial awareness to the monitoring stack
  • Combined activity and location signals into higher-level caregiver alerts for risky situations
// 05 — OUTCOMES
RESULTS AND LESSONS
  • Turned two separate research tracks into one end-to-end monitoring concept rather than leaving them as isolated models.
  • Showed that context-aware monitoring improves when activity inference and spatial inference are interpreted together.
  • Produced a stronger systems story by linking model quality, IoT data flow, dashboarding, and alert logic in one design.
