Fujitsu software will detect your pulse in the face

Fujitsu has developed software that measures the user's pulse based on the color of a person’s face, Engadget reports.
The measurement process takes only 5 seconds, but during this time the subject must be stationary.
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.
No detailed information about the technology, and most importantly - how accurate it is, is not currently available.
