Method and apparatus for evaluating human stress using photoplethysmography |
摘要 |
A method of evaluating human stress using photoplethysmography (PPG) includes defining at least one PPG parameter, radiating light having at least one wavelength, which reacts to a blood component to be measured, at a measuring target and measuring a PPG signal from the measuring target during a predetermined period of time, and evaluating a level of human stress using a plurality of stress indexes obtained from the PPG parameter.
