Researchers at the Worcester Polytechnic Institute (WPI) in the United States have created a new application that turns smartphones into cutting-edge diagnostic tool that can measure the heart beats and the respiration rate through the in-built camera.
Lead researcher Professor Ki Chon said that the medical professionals can check the vital signs of a patient simply by putting his finger on the camera of a smartphone or a tablet.
AdvertisementChon added that the app works by analyzing the video clips that are recorded when the patient presses his finger on the camera.
"Imagine a technician in a nursing home who is able to go into a patient's room, place the patient's finger on the camera of a tablet, and in that one step capture all their vital signs. This gives a patient the ability to carry an accurate physiological monitor anywhere, without additional hardware beyond what's already included in many consumer mobile phones", Chon said.
