Activity classification — IMU (motion) + mic (context) → walking / running / stairs / cycling.
Gesture + voice control — APDS-9960 + mic → "swipe + 'next'" multimodal commands.
Indoor air-quality alert — temp + humidity + pressure → trend anomaly.
Fall detection — IMU + mic (impact) → fewer false positives than IMU alone.
