    Abstract: Systems, methods, and computer programs for eye tracking involving a camera that is operated according to eyelid position. In one embodiment, an inward-facing head-mounted camera captures images of an eye. A head-mounted device emits electromagnetic waves towards the eye and measures reflections of these waves from the eye. The average rate of reflection measurements is at least ten times the average rate of image capture. A computer detects the position of at least one of the eyelids covering the eye based on the reflection measurements. And the camera operation is adjusted according to the eyelid position in a manner that decreases, in the captured images, areas depicting the eyelids, and optionally increases areas depicting the iris.

    Abstract: Detecting a respiratory tract infection (RTI) based on changes in coughing sounds, which can provide an early warning of infection with a disease like COVID-19, as well as indications of its progression and severity. In one embodiment, the system includes smartglasses, with sensors mounted thereto, which include an acoustic sensor mounted at a fixed position relative to a user's head, and a movement sensor. A computer receives current measurements of the user, taken with the sensors, while there were head movements that characterize coughing, and also earlier measurements of the user, taken with the sensors, while the user had a known extent of the RTI and while there were head movements that characterize coughing. The computer detects a change relative to the known extent of the RTI based on a difference between the current measurements and the earlier measurements.

    Abstract: Described herein are embodiments of systems and a method to identify orthostatic hypotension and postural-orthostatic tachycardia syndrome. One system includes a head-mounted device configured to measure photoplethysmographic signal (PPG signal) at a region on a user's head, and a head-mounted camera configured to capture images indicative of the user's posture. Additionally, the system includes a computer that calculates systolic and diastolic blood pressure values based on the PPG signal, and identifies orthostatic hypotension based on a drop of systolic blood pressure below a first threshold, and/or a drop of diastolic blood pressure below a second threshold, within a predetermined duration from a transition in the posture from supine to sitting posture, or from sitting to standing posture.

    Abstract: This disclosure describes various systems for collecting thermal measurements of regions of a user's face. Each of the systems includes a frame configured to be worn on the user's head, and one or more lightweight thermal cameras that are coupled to the frame and configured to take thermal measurements of a region of interest on the user's face. Due to their coupling to the frame, the thermal cameras remain pointed at their respective regions of interest even when the user's head performs angular movements. The thermal measurements collected by some embodiments of the systems described herein may be utilized for a variety of applications that involve detecting different types of physiological responses or medical disorders.

    Abstract: Wearable devices for taking symmetric thermal measurements. One device includes first and second thermal cameras physically coupled to a frame worn on a user's head. The first thermal camera takes thermal measurements of a first region of interest that covers at least a portion of the right side of the user's forehead. The second thermal camera takes thermal measurements of a second ROI that covers at least a portion of the left side of the user's forehead. Wherein the first and second thermal cameras are not in physical contact with their corresponding ROIs, and as a result of being coupled to the frame, the thermal cameras remain pointed at their corresponding ROIs when the user's head makes angular movements.

    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.
