Detecting stress based on thermal measurements of the face
First Claim
1. A system configured to detect a stress level, comprising:
- an inward-facing head-mounted thermal camera (CAM) located less than 10 cm from a user'"'"'s head and configured to take thermal measurements of a region on a periorbital area (THROI1) of the user; and
a computer configured to generate feature values based on THROI1, and to utilize a model to detect the stress level based on the feature values;
wherein the model was trained based on;
previous THROI1 taken while the user was under elevated stress, and other previous THROI1 taken while the user was not under elevated stress.

Abstract
Described herein are systems and methods for detecting a stress level of a user. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) and a computer. CAM takes thermal measurements of a region on a periorbital area (THROI1) of the user. The computer generates feature values based on THROI1, and utilizes a model to detect the stress level based on the feature values. The model was trained based on: previous THROI1 taken while the user was under elevated stress, and other previous THROI1 taken while the user was not under elevated stress. Some embodiments may utilize additional thermal cameras that take thermal measurements of other regions on the face, which may be utilized to detect the stress level.

17. A system configured to alert about stress, comprising:
-
first and second inward-facing head-mounted thermal cameras (CAM1, CAM2) located at least 0.5 cm to the right and to the left of the vertical symmetry axis that divides the user'"'"'s face, respectively; CAM1 and CAM2 are configured to take thermal measurements of regions on the periorbital areas of the right and left eyes (THROI1 and THROI2, respectively) of the user; and a user interface configured to provide an alert about a stress level reaching a threshold;
wherein the stress level is determined based on THROI1 and THROI2. - View Dependent Claims (18)
