摘要：
Disclosed herein are systems and methods for detecting a physiological response using different types of photoplethysmography sensors. Examples of physiological responses that may be detected include an allergic reaction, a stroke, a migraine, stress, certain emotional responses, manifestation of pain, and blood pressure. In one embodiment, a head-mounted contact photoplethysmography device measures a signal indicative of photoplethysmogram signal at a first region that includes exposed skin on a user's head (PPG signal). A camera, located more than 10 mm away from the user's head, captures images of a second region that includes exposed skin on the user's head. A computer detects the physiological response based on: (i) imaging photoplethysmogram signals (iPPG signals) recognizable in the images, and (ii) correlations between the PPG signal and the iPPG signals.
