How do wearable devices track user health metrics?
Wearable devices track user health metrics through embedded sensors that monitor various physiological indicators. Common sensors include accelerometers for tracking movement, heart rate monitors for measuring cardiac activity, and gyroscopes to assess orientation and balance. Data collected through these sensors is processed and analyzed, often using machine learning algorithms, to provide insights into health conditions like activity levels, sleep patterns, and overall fitness. Many wearables also connect to smartphones, allowing users to visualize their health data in real-time and share it with healthcare providers for better health management.
