The wearable systems presented include the Automatic Ingestion Monitor (AIM-2) for monitoring diet, nutrition, and ingestive behavior; the Screen Time Tracker (STT) for quantifying screen exposure in children aged 2–5 years; SmartStep, an insole-based sensor for monitoring physical activity and gait, and its successor, Smart LaceLock; the Personal Automatic Cigarette Tracker (PACT) for monitoring combustible cigarette consumption; and the Flexible Robust Instrumentation of Electronic Nicotine Delivery Systems (FRIENDS) for monitoring vaping behavior.
The tutorial will address sensor design considerations, embedded processing, data acquisition, and power management, as well as signal processing and ML/AI pipelines for behavior recognition and event detection. Lessons learned from real-world deployments will be discussed, with demonstrations of selected sensor systems.
