DETECTING PHYSIOLOGICAL RESPONSES USING THERMAL AND VISIBLE-LIGHT HEAD-MOUNTED CAMERAS

摘要

Some aspects of this disclosure involve head-mounted systems that are utilized to take thermal measurements of a user's face to detect various physiological responses, such as an allergic reaction, stress, a headache, a stroke, to name a few. Typically, these systems involve one or more head-mounted thermal cameras that may be physically coupled to a frame worn on the user's head and are utilized to take thermal measurements of one or more regions of interest (ROIs). Some of the systems described in this disclosure are intended for "real world", uncontrolled day-to-day use, in which detection of the physiological response may be hampered by "confounding factors". A confounding factor can be a cause of warming and/or cooling of certain ROIs the face, which is unrelated to a physiological response being detected, and as such, can reduce the accuracy of the detection of the physiological response.
