The Avanti Technology Review
Japanese company Fujitsu announced recently that it is close to finish developing a technology that measures a personís pulse in real time using a built-in camera or webcam in a PC, smartphone or tablet. The technology allows the user to check the pulse only by pointing a camera at his or her face. It is a simple procedure and the results can be achieved in only five seconds, the companyís officials say.
The personís pulse is detected by measuring variations in the brightness of the personís face thought to be caused by the flow of blood. The technology is based on the characteristic of hemoglobin in blood, which absorbs green light, so when blood is flowing faster than normal our skin becomes redder. It automatically chooses moments when the personís body and face are relatively still to minimize the effects of irrelevant data on measurements, Fujitsu stated in a press release.
As most of its functions are automatic, the smartphone knows when the userís face is pressed against its screen during the call and it can continue to monitor the personís pulse even when he or she is moving, according to the local press.
Pulse detectors built into gates at event sites or control points at airports could also be used a possible security application by detecting people in ill health and people acting suspiciously, Fujitsuís officials think.
The technology will be put into use starting with this year.
