American comic book hero Superman, his "X-ray eyes" everyone can see through eyes, bones, muscles, heartbeat list no doubt. We can not Superman, to see through the bones, muscles rely on the hospital's X-ray machine, but through the cameras and software, it touches everyone can learn to see the face of the super powers recognize heartbeat Oh!
Principle is very simple, when the blood toward the heart beat up the head when the head pulse will fluctuate, sometimes after exercise, heart rate is very severe, you will feel the head even with the heartbeat vibration. The vibration level is small, so we usually difficult to directly see it with your eyes, but as long as the face image shot down, with computer analysis, we can know heartbeat.
Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Laboratory (Computer Science and Artificial Intelligence Laboratory) on the use of this principle, wrote a face tracking and calculating the displacement of the software, tracking face 500 to 1000 points displacements , we can measure the heartbeat.
Research team recruited 18 people to do the test, the results test out the results are almost as accurate with the electrocardiogram.
There are many other techniques previously can also be measured by photographing the heart, including Microsoft Xbox One of Kinect 2, the principle is to use the blood most marked when the head, face, vasodilation, the red color, the resulting color, but the color judgment accuracy as displacement, on the other hand, the use of displacement techniques have the advantage that even if the other wearing a mask can also measure the heartbeat ─ ─ X-ray eyes the way it is not? ─ ─ because the mask will follow head with the move, with the component technology can be no solution.
Perhaps Microsoft should hurry with MIT for advice, the displacement technology into Kinect 2 on top, so that later you can play the game wearing a mask measuring heart rate,but the question is who is wearing a mask to play the game ah?
