Hi, I am Paul Chin, the inventor of Webcam Biofeedback. I created this technology way back in 2008 - 2010 and built the world's first webcam biofeedback that could be used to help people relax, reduce high blood pressure and release stress. My system uses the webcam to detect breathing and play relaxation games that uses the breath. I continued to work on it intermittently throughout the years. On 2021 February 15,  I have fully revived the project by re-acquiring this domain, i.e. webcambiofeedback.com which was originally mine. And this is the website you are now viewing. You can contact me via my youtube channel:
