Webcam measures heartbeat and breathing

Philips Healthcare developed a technology, called Vital Signs, that utilizes a simple webcam to measure bodily functions like heartbeat and breathing. The only thing one has to do is to position him or herself for 10 to 30 seconds in front of the camera. Philips claims that the measurements are as accurate as traditional ways of measuring the same functions using sensors attached to the body.
This application is also available for the iPad using the built in camera.
