Systems for collecting thermal measurements of the face

A method for detecting a physiological response, comprising:

• receiving, by a processor, thermal measurements from a system configured to be worn on a user's head;
• wherein the system comprises first, second, third, and fourth thermal cameras;
• the first and third thermal cameras are located to the right of the vertical symmetry axis that divides the face;
• the second and fourth thermal cameras are located to the left of the vertical symmetry axis;
• and the third and fourth thermal cameras are located at least 1 cm below the first and second thermal cameras, respectively;
• the first thermal camera is configured to take thermal measurements of a first region of interest (THROI1), wherein ROI1 covers a portion of the right side of the user's forehead;
• the second thermal camera is configured to take thermal measurements of a second ROI (THROI2), wherein ROI2 covers a portion of the left side of the forehead;
• the third thermal camera is configured to take thermal measurements of a third ROI (THROI3), wherein ROI3 covers a portion of the right side of the user's upper lip;
• the fourth thermal camera is configured to take thermal measurements of a fourth ROI (THROI4), wherein ROI4 covers a portion of the left side of the user's upper lip;
• generating feature values based on THROI1, THROI2, THROI3, and THROI4;
• and
• utilizing, by the processor, a machine learning-based model for calculating, based on the feature values, a value indicative of whether the user had the physiological response.

• comparing, by the processor, one or more values derived from THROI1, THROI2, THROI3, and THROI4 to a threshold;
• and
• responsive to the one or more values reaching the threshold, indicating that the user had the physiological response.
