Fujitsu pulse app for PC, smartphone cameras
Fujitsu’s R&D division Fujitsu Laboratories has created a new technology that can read your pulse with the camera or webcam of a PC, tablet or smartphone.
Specifically, the technology monitors pulse rate by noting the difference in the brightness of your face that is caused by blood flow, leveraging on haemoglobin’s tendency to absorb green light.
Using a webcam or camera attached to a computer or smartphone, the technology can count a person’s pulse in merely five seconds. However, you need to remain stationary for it to obtain precise results, as the software will only start if you stop moving.
This technology will be demonstrated at this year’s General Conference of the Institute of Electronics, Information and Communication Engineers at Gifu in Japan, which kicks off on 19 March. This breakthrough offers many potential uses such as security applications as well as health monitoring and maintenance.
In particular, health practitioners will find it easier to monitor a patient’s pulse as it does away with specialised equipment that needs to be constantly worn by the patient. It can also continuously read your pulse even if you’re busy at work. Whether you are writing emails, teleconferencing or sitting in front of a PC, it can gauge your pulse during brief intervals.
Furthermore, this technology can also be used for security. It can be installed in airport cameras to detect unusually high pulse rates, which could be an indication that someone is planning to do something bad. Aside from that, it can also be used as a lie detector.
