Blood pressure measuring smartglasses
First Claim
1. A system configured to calculate blood pressure, comprising:
- an inward-facing head-mounted camera (HCAM1) configured to capture images of a first region of interest (IMROI1) that comprises a portion of exposed skin of the user'"'"'s face;
an outward-facing head-mounted camera (HCAM2) configured to capture images of a second region of interest (IMROI2) that comprises exposed skin on a hand of the user; and
a computer configured to calculate a blood pressure value for the user based on first and second photoplethysmographic signals (iPPG1, iPPG2) recognizable in IMROI1 and IMROI2, respectively.

Abstract
A system for detecting blood pressure based on imaging photoplethysmography (iPPG) includes an inward-facing head-mounted camera to capture images of a first region of interest (IMROI1) that comprises a portion of exposed skin of the user'"'"'s face, and an outward-facing head-mounted camera to capture images of a second region of interest (IMROI2) that comprises exposed skin on a hand of the user. The head-mounted cameras may be coupled to a frame of eyeglasses or smartglasses, and the system further includes a computer to calculate a blood pressure value for the user based on first and second photoplethysmographic signals recognizable in IMROI1 and IMROI2.
