Challenges

Technical challenges overcome

Building Lumo required solving complex technical problems to ensure reliable, real-time performance.

Maintaining Stable Sampling Rate

While integrating the two biosensors on the wearable device, I observed that the intended 50Hz sampling rate was inconsistent, with sporadic delays that led to dropped sensor readings.

Solution:

  • Revised approach from polling-based loop to hardware interrupts
  • Configured data-ready pins on each sensor
  • Implemented FreeRTOS task scheduling
  • Optimized timer management for consistent sampling

Rapid Anomaly Detection

Processing incoming sensor data in real time on the Raspberry Pi-powered hub device was challenging: the data needed to be quickly filtered, normalized, and analyzed in order to trigger immediate and timely alerts.

Solution:

  • Implemented multi-threaded processing within the hub device
  • Separated local data processing, voice interaction, and BLE data reception tasks
  • Optimized data pipeline with asynchronous I/O using libevent
  • Significantly reduced latency between anomaly detection and alert generation
