Here's an overview of how Habitone measures your autonomic nervous system to help you monitor your stress and wellness. Habitone analyzes the HRV by measuring the rhythm of your heartbeat through your smartphone camera.
First, place your fingertip on the camera lens. The camera sensor detects changes in blood flow in your fingertip, accurately measuring your heart rate.
This method, called photoplethysmography, is the same technology used in LED-based heart rate monitors found in wearables like the Apple Watch. Habitone achieves comparable accuracy in heart rate measurement.
From the one-minute heart rhythm data, Habitone analyzes heart rate variability to quantify the state of your autonomic nervous system. The autonomic nervous system controls various organs and is closely related to changes in physical condition and stress. It's medically proven that heart rate variability can indicate the state of the autonomic nervous system, and the methods for calculating these indicators are well-established[1]. Habitone leverages this scientific knowledge.
