Fujitsu Labs announces the development of their new technology that allows detection and analysis of a person's pulse rate by only using the image of that person's face taken by a web camera.
It's been just a short while since Fujitsu Laboratories Ltd. has unveiled their new high-speed data transfer technology, but now, they have yet another novel technology concept on an entirely different field. This time, they have developed a new detection analysis system, which is claimed to be able to observe and accurately measure human pulse rates using only the information found in an image produced by a web camera.
The working principle of their new technology is based on the observation that the human skin shows very slight difference in color tones or variations in brightness depending on the flow of blood in that certain area. The phenomenon is explained as a common characteristic of hemoglobin, in which it absorbs light in the green part of the spectrum, and then causes the visual change in color.
Fujitsu's technology first takes a shot of a person's face using a web camera for about five seconds, then by looking at the subtle changes in color as time passes, the analyzing software can then produce a measure of that person's pulse rate. Accuracy is achieved by the technology using a cross-referencing method to its surroundings. For example, it would not take irrelevant data such as a significant change in the face's subsequent positions.
What is quite astonishing about this new technology is that it does not actually require the use of specific hardware. It only needs the analysis software, and any sufficiently good web camera for their system to work as devised.
According to Fujitsu, the most important potential use for this kind of technology would be on health and security monitoring systems, or on any application or field that would require easy access to vital body information, without the need for the people to strap on and use complex equipment.
