How It Works

What if the simple act of looking into your smartphone camera reveals your vital physiology, through the use of innovative AI technology?


Revealing An Individual’s
Physiology, Without Contact

For its contactless health parameter extraction, SignalADoc VSm uses remote photoplethysmographic imaging (rPPG). rPPG is a camera-based solution for contactless cardiovascular monitoring, proven to be as accurate as traditional PPG devices. Our technology measures the changes in red, green, and blue light reflected from the skin and quantifies the contrast between specular reflection and diffused reflection.
