Abstract: Systems, methods, and computer programs for eye tracking. In one embodiment, an eye tracking system includes a head-mounted device that takes measurements indicative of a position of the eye of a user. A head-mounted camera captures an image of the eye. A computer calculates the position of the eye based on the measurements, utilizes the position of the eye to crop the image around the pupil, and provides a cropped image to a video-based eye tracker. Optionally, the size of the cropped image is less than a third of the size of its respective uncropped image. Optionally, the head-mounted device includes one or more of the following: a photosensor-oculography device (PSOG), an electrooculography device (EOG), an electromyography device (EMG), an optical flow sensor, and a range sensor. Optionally, the image-based eye tracker calculates, based on the cropped image, at least one of pupil diameter and pupillary response.

Abstract: Embodiments disclosed herein involve a wearable-based system that can help determine in a privacy-preserving mariner whether a user is healthy (and thus poses low risk of contagiousness), and use determinations of this nature to grant passage through a doorway. In one embodiment, a wearable device takes measurements of a user comprising a photoplethysmogram signal (PPG signal) and a temperature measurement. A computer calculates a health score based on a difference between baseline measurements of the user, measured one or more days earlier, and more current measurements of the user. Additionally, the computer calculates an extent of similarity between characteristics of the PPG signal in the current measurements and characteristics of the PPG signal in the baseline measurements. The computer authorizes the user's passage through the doorway responsive to the health score reaching a first threshold and the extent of the similarity reaching a second threshold.

Abstract: Often the physiological and emotional state of a person can be associated with certain cortical activity that can cause certain thermal patterns on the person's forehead. Thus, thermal measurements of the forehead may be used to differentiate between user states. In one embodiment, a system includes at least one inward-facing head-mounted thermal camera (CAM) that takes thermal measurements of at least first and second regions on the right side of a user's forehead (THR1 and THR2, respectively), and thermal measurements of at least third and fourth regions on the left side of the forehead (THL1 and THL2, respectively). The middles of the first and third regions are at least 1 cm above the middles of the second and fourth regions, respectively. The system also includes a computer that determines, based on THR1, THR2, THL1, and THL2, whether the user is in a normal state or an abnormal state.

Abstract: Disclosed herein are systems and methods for tracking facial expressions efficiently. In one embodiment, a system includes a non-contact head-mounted electro-optical sensor (e.g., an inward-facing head-mounted camera), which measures reflections from a region on a user's head, which are indicative of facial expressions of the user. The system also includes a computer that detects, based on the reflections, a type of facial expression expressed by the user, which belongs to a group comprising neutral facial expressions and non-neutral facial expressions. The computer uses this detection to determine how to proceed to read the electro-optical sensor: the computer reads the electro-optical sensor at a first average bitrate (b1) when the user expresses a facial expression from among the neutral facial expressions, and reads the electro-optical sensor at a second average bitrate (b2) when the user expresses a facial expression from among the non-neutral facial expressions, where b2>b1.

Abstract: The three-dimensional (3D) shape of the exhale stream from a user's nostrils is often correlated with the user's state (e.g., an emotional state and/or a certain health condition). Thus, identifying the shape of a user's exhale stream can help determine the user's state. In one embodiment, a system that selects a state of a user includes at least one inward-facing head-mounted thermal camera that takes thermal measurements of at least three regions below the nostrils (THS). THS are indicative of shape of the exhale stream (SHAPE). The system also includes a computer that generates feature values based on THS, which are indicative of the SHAPE, and utilizes a model to select the state of the user, from among potential states of the user, based on the feature values. Optionally, the system includes a user interface that present the user's selected state.

Abstract: Described herein are systems and methods for detecting a physiological response based on facial skin color changes (FSCC) recognizable in images taken with an inward-facing head-mounted visible-light camera (VCAMin). Some examples of physiological responses whose manifestation involves FSCC include emotional responses (which at times may be hidden to the naked eye), and physiological signals such as a heart rate, heart rate variability, and/or a breathing rate. In one embodiment, a system that detects a physiological response based on FSCC includes VCAMin that takes images of a region of interest (IMROI) on a user's face, which is illuminated by ambient light, and a computer that detects the physiological response based on FSCC recognizable in IMROI. Optionally, the system includes an outward-facing head-mounted visible-light camera (VCAMout) that takes images of the environment (IMENV), and the computer detects the physiological response also based on IMENV.
