Detecting stress based on thermal measurements of the face

A system configured to alert about stress, comprising:

• first and second inward-facing head-mounted thermal cameras (CAM1, CAM2) configured to be held at least 0.5 cm to the right and to the left of the vertical symmetry axis that divides a user's face, respectively;
• CAM1 and CAM2 are further configured to take thermal measurements of regions on the periorbital areas of the right and left eyes (THROI1 and THROI2, respectively) of the user;
• wherein the fields of view of CAM1 and CAM2 do not cover a region outside the user's face;
• 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.
