Eyeglasses having inward-facing and outward-facing thermal cameras
First Claim
1. A system configured to detect a physiological response, comprising:
- an inward-facing head-mounted thermal camera (CAMin) configured to take thermal measurements of a region of interest (THROI) on a user'"'"'s face;
wherein CAMin does not occlude the region of interest (ROI) and is located less than 15 cm from the user'"'"'s face;
an outward-facing head-mounted thermal camera (CAMout) configured to take thermal measurements of the environment (THENV), and is located less than 15 cm from the face; and
a computer configured to detect the physiological response from feature values generated based on THROI and THENV.

Abstract
Described herein are systems and methods for detecting a physiological response based on thermal measurements while accounting for effects of the environment. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAMin) that takes thermal measurements of a region of interest (THROI) on a user'"'"'s face, and an outward-facing head-mounted thermal camera (CAMout) that takes thermal measurements of the environment (THENV). CAMin does not occlude the region of interest, and the system further includes a computer that detects the physiological response based on THROI and THENV. Optionally, the computer generates feature values based on sets of THROI and THENV, and utilizes a machine learning-based model to detect, based on the feature values, the physiological response.

19. A method for detecting a physiological response, comprising:
-
taking thermal measurements of a region of interest (THROI) on a user'"'"'s face utilizing an inward-facing head-mounted thermal camera (CAMin); taking thermal measurements of the environment (THENV) utilizing an outward-facing head-mounted thermal camera (CAMout) worn by the user; generating feature values based on THROI and THENV; and utilizing a machine learning-based model to detect the physiological response based on the feature values;
wherein one or more of the feature values are generated based on THENV and are utilized to account for at least some heat transferred from the environment to the region of interest. - View Dependent Claims (20, 21)
