Fujitsu, a Japanese electronics maker, has recently discovered a biometric technology that can tell the heartbeat by looking at your face. This is made possible by the company’s specialized camera software.

As oxygen enters and leaves the skin cells, their color changes slightly. Although we do not understand it with the naked eye, it is possible to determine its rate on smartphones, tablets or computers using Fujitsu’s new technology.

Although the whole digital strategy is quite subtle and complex, its principles are very simple. The results are based on the rate of skin discoloration between blood transfusions and the average time required. Since blood flow is directly linked to the heartbeat, the idea of ​​determining the pulse rate by analyzing the color variation of the cell has come up.

The Fujitsur project can calculate your pulse rate in just five seconds. In this case, only the color (greenish) absorbed by the hemoglobin in the blood is used to show the correct result.

With the advent of this new technology comes a simple and important tool for monitoring and caring for health. The heart-determining technology is expected to hit the market in the current financial year. Since the Fujitsu camera currently displays results in five seconds, efforts are being made to upgrade it to “real time” as soon as possible.

However, this is not the first application to calculate the pulse on a smart device. For example, Apple has already released such software for iOS. Let’s see if Fujitsu can offer something better.
