The technology that allows users to track physical activity using wearable devices includes accelerometers, gyroscopes, and heart rate monitors. These sensors gather data about movements, exertion levels, and other physiological signals. Wearable devices like fitness trackers and smartwatches utilize this data to provide insights into users’ health and activity levels, allowing them to set goals, monitor progress, and receive feedback on their fitness activities. This technology fosters healthier lifestyles and promotes well-being.
