Fujitsu Real-Time Monitoring System Measures Your Heart Rate by Looking at Your Face

Wednesday, March 20th 2013. | Mobile Phones

Do you know that freaky lies detector which uses some wired sensors attached to the suspect’s body? Usually, it’s paired with a monitor that displays how the suspect’s hear rate is going as he speaks. That machine actually works based on the fact that a person’s hear rate is almost impossible to be manipulated. It changes, either slightly or significantly, as the person faces doubt, fear, happiness, and other situations.

While that machine is fine, its effectiveness will go down to nearly zero if there are many suspects whose heart rate must be monitored at the same time. World needs a faster system and Fujitsu’s latest invention fits the bill. The real-time monitoring system developed by the company makes use of the front-facing camera of a mobile device to read different brightness on the suspects face. From there, it can tell whether their heart rate slows down or spikes up. Mind you, it only needs as little as 5 seconds to measure a person’s hear rate; no wires, no special device.

Although most of us don’t notice it, the brightness of our face differs each time we run into different situations. This is because the blood flow on our face changes in intensity as our hear rate shifts. The capability of hemoglobin contained within the blood to absorb green light will also be affected. It is the footprint of such green light that is read by Fujitsu’s system.

Fujitsu expects that its real-time monitoring system can be used in many public places to detect anyone who is about to make harm of the others. Its application is not only limited for security purpose, though, because the company says that its future mobile devices will sport it as well. So later in the future, when Japanese girls suspect that their boyfriend is cheating, they just need to interrogate him using their smartphone. Scary, huh?
