Fujitsu - Real-Time Pulse Monitor Using Facial Imaging

Using built-in cameras in PCs or smartphones, a new technology to be presented this week by Fujitsu Laboratories can measure pulse in as little as five seconds using built-in cameras in PCs or smartphones. It works by measuring variations in the brightness of the person's face thought to be caused by the flow of blood. It is based on the characteristic of hemoglobin in blood, which absorbs green light. It requires no special hardware and can measure pulse rate simply by pointing a camera at a person's face for as little as five seconds.
