Abstract: In one embodiment, a method includes accessing, from a first sensor of a wearable device, motion data representing motion of a user and determining, from the motion data, an activity level of the user. The method includes selecting, based on the activity level, an activity-based technique for estimating the breathing rate of the user, which is used to determine a breathing rate of the user. The method further includes determining a quality associated with the breathing rate and comparing the determined quality with a threshold. If the determined quality is not less than the threshold, then the method includes using the determined breathing rate as a final breathing-rate determination for the user. If the determined quality is less than the threshold, then the method includes activating a second sensor of the wearable device and determining, based on data from the second sensor, a breathing rate for the user.

Abstract: A method includes receiving multimodal data collected using at least one wearable device during an assessment window. The method also includes extracting biomarker features from the multimodal data, based on changes in the extracted biomarker features. The method also includes detecting that a stress event occurred during the assessment window. The method also includes accessing a plurality of templates of patterns in biomarker features, wherein a first subset of the templates is associated with unhealthy response to stress and a second subset of the templates is associated with healthy response to stress. The method also includes determining whether the stress event corresponds to a healthy response or an unhealthy response based on similarities between a pattern in the extracted biomarker features and the plurality of templates. The method also includes responsive to the stress event corresponding to an unhealthy response, providing a stress management recommendation.

Abstract: Energy-efficient monitoring and detection of atrial fibrillation using an electronic device can include scheduling, by the electronic device, monitoring periods during which the electronic device intermittently monitors a user of the electronic device for atrial fibrillation. The scheduling can be based on determining an AF risk specific to the user. Time intervals between successive AF monitoring periods can be modulated by the electronic device in response to detecting a change in the AF risk.

Abstract: Limb motion tracking using a single sensor can include capturing acceleration data. The acceleration data can be captured in real time by an IMU sensor of a wearable device worn on a limb of a user. Orientation data can be captured in real time by the IMU sensor concurrently with the acceleration data. Estimated positions of joints of the limb can be determined based on the acceleration data and the orientation data, the joints positions estimated using a machine learning model and relative to a coordinate system. Motion of the limb can be tracked based on the estimated positions determined at different times as the user moves the limb.

Abstract: A method includes receiving, by an electronic device, sensor data during a spirometry test of a user, the sensor data comprising audio data of the user and distance data of a distance from a face of the user to the electronic device. The method also includes obtaining, by the electronic device, an amount of air volume exchange and at least one pulmonary health parameter that are determined based on the audio data and the distance data. The method also includes presenting an indicator on a display of the electronic device for use by the user or a medical provider, the indicator representing the amount of air volume exchange.

Abstract: In one embodiment, a method includes accessing a window of motion data collected by a motion sensor of a device worn by a user and selecting motion data in the window about or more particular axes of the motion sensor. The method further includes determining a ballistocardiogram (BCG) signal in the selected motion data and determining whether the BCG signal in the selected motion data satisfies a signal-quality metric. If the BCG signal in the selected motion data satisfies the signal-quality metric, then the method includes (1) determining one or more heart-beat metrics of the user from the selected motion data; and (2) estimating, based on the one or more determined heart-beat metrics, a stress condition of the user at a time coincident with the window of motion data.

Abstract: In one embodiment, a method includes accessing a video of a user's face. The method further includes accessing, for each image frame in the video, (1) one or more facial landmarks determined by a facial landmark detection (FLD) model and (2) a corresponding determined position in the image for each facial landmark. The method further includes determining, based on the one or more facial landmarks and corresponding positions, a motion of the user's face in the captured video; extracting, from the determined motion of the user's face, a corrected motion signal of the user's face; adjusting, based on the extracted corrected motion signal of the user's face, the positions of one or more facial landmarks in the image frames; and determining, based at least in part on the adjusted positions of the facial landmarks in the sequential images of the video, one or more vital signs of the user.
