PulseFeedback is a browser based tool that detects your heart rate using your device's camera. It analyzes subtle color changes in your skin caused by blood flow, a technique known as photoplethysmography (PPG). The entire process happens in real time, with no wearable hardware required. The tool displays your pulse as a visual or numerical feedback, creating an "extra sensory experience" as described on the site.
