How It Works
- Your heartbeat causes micro color changes on your face. When your heart beats, a pulse of blood sent through your blood vessels. Blood absorbs light. When more blood flows through the vessels, less light hitting your face is being reflected. Our software uses camera and a software algorithm to detect these micro changes, with beat-to-beat accuracy. The algorithm is built based on reliable non-contact photoplethysmography concept.
- This is an on-going research being done in many research labs. To read on notable source regarding this research, pleaseGoogle it, or search on YouTube.
