Fujitsu software will detect your heart rate in your face

Fujitsu has developed software that measures the user's heart rate based on facial color data, Engadget reports .
The measurement process takes only 5 seconds, but during this time the test subject should be motionless.
The principle of action is to determine changes in the shade of a person's face. Hemoglobin in the blood is known to absorb green light.
There is currently no detailed information about the technology, and most importantly, how accurate it is.
