Detecting physiological responses while accounting for touching the face
First Claim
1. A system configured to detect a physiological response, comprising:
- an inward-facing head-mounted thermal camera (CAM) configured to take thermal measurements of a region of interest (THROI) on a user'"'"'s face;
a sensor configured to provide measurements (M) indicative of times at which the user touches the region of interest (ROI);
whereby touching the ROI affects THROI; and
a computer configured to detect the physiological response based on THROI and M.

Abstract
Described herein are systems and methods for detecting a physiological response based on thermal measurements while accounting for touching the face. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) that takes thermal measurements of a region of interest (THROI) on a user'"'"'s face, and a sensor that provides measurements (M) indicative of times at which the user touches the region of interest (ROI). The system also includes a computer that detects the physiological response based on THROI and M. Optionally, the computer generates feature values based on THROI and M, and utilizes a model to detect, based on the feature values, the physiological response. Optionally, the model was trained based on samples, each including: (i) feature values generated based on previous THROI taken while M indicated touching the ROI, and (ii) a corresponding label indicative of an extent of the physiological response.

17. A method for detecting a physiological response, comprising:
-
taking, using an inward-facing head-mounted thermal camera (CAM), thermal measurements of a region of interest (THROI) on a user'"'"'s face; taking measurements (M) indicative of times at which the user touches the region of interest (ROI); and detecting the physiological response based on THROI and M;
wherein, on average, detections of the physiological response based on THROI and M are more accurate compared to detections of the physiological response based on THROI without M. - View Dependent Claims (18, 19, 20)
