1. A system configured to calculate blood pressure, comprising:
a first inward-facing head-mounted camera (HCAM1) configured to capture images of a first region of interest (ROI1) located on the face below the eyes and above the lips (IMROI1) of a user;
a second inward-facing head-mounted camera (HCAM2) configured to capture images of a second region of interest (ROI2) comprising a portion of a temple and/or forehead (IMROI2) of the user; and
a computer configured to calculate a blood pressure value for the user based on first and second imaging photoplethysmographic signals (iPPG1, iPPG2) recognizable in IMROI1 and IMROI2, respectively.
