Abstract:
This paper presents a novel solution for non-invasive real-time heart rate monitoring by processing of Near Infrared (NIR) generated streams, provided by a low-cost, easy-to-use sensor, such as Microsoft Kinect™. The standard method to monitor physiological information exploits photoplethysmographic images. In fact, the changes in blood volume can be determined from the spectra of radiation reflected from (or transmitted through) body tissues. Using a mathematical processing, the study shows how it is possible to real-time estimate the heart rate of people sitting for 1 minute in front of the sensor at distance 1 meter by analysing the NIR stream and without wearing any other sensors. In order to prove the correctness of the method proposed, 35 different subjects are involved in the test phase. During the tests, each subject wears also a pulse oximeter for comparing the values calculated by our method.
