Fujitsu Develops Real-Time Pulse Monitor Using Facial Imaging

March 26, 2013 Fujitsu Laboratories has announced that it has developed a technology to measure a person's pulse in real time using a built-in camera or webcam in a PC, smartphone, or tablet.

The technology detects a person's pulse by measuring variations in the brightness of the person's face thought to be caused by the flow of blood. The measurement process makes use of a characteristic of hemoglobin, 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. It also automatically chooses moments when the person's body and face are relatively still to minimize the effects of irrelevant data on measurements. The lab reports the new technology has a wide range of potential uses, including health monitoring and maintenance as well as security applications.
