A method for monitoring cardiac health of a user of a
mobile computing device includes activating an imaging device associated with the
mobile computing device in response to a trigger indicating a presence of the user within a
field of view of the imaging device. The method also includes obtaining, via the imaging device, video data of a face of the user for a time period. Further, the method includes determining, via a
machine-learned model programmed in a processor of the
mobile computing device, one or more cardiac
metrics based on, at least, the video data. The one or more cardiac
metrics includes, at least, a
heart rate of the user. Furthermore, the method includes determining one or more cardiac biomarkers based, at least in part, on the one or more cardiac
metrics. The one or more cardiac biomarkers includes, at least, a
resting heart rate of the user. In addition, the method includes causing a display of the mobile computing device to display, at least, the one or more cardiac biomarkers in response to a
user input.
