1. A processing system for physiological sensing in a wearable device, the system comprising a processor in communication with one or more types of memory, the processor configured to:
generate a multi-faceted feedback for a user, wherein generating the multi-faceted feedback comprises:
generating a baseline physiological sampling schedule for a user;
generating a quality-aware feedback of the user;
generating a user-state-aware feedback of the user;
polling a source external to the wearable device for contextual data associated with the user, the contextual data comprising at least one of calendar data and email data; and
generating a context-aware feedback of the user, the context-aware feedback indicating a historically stressful context for the user based in part on a current location of the user and the polled contextual data;
generate an adjusted physiological sampling schedule for the user based at least in part upon the multi-faceted feedback, the adjusted physiological sampling schedule comprising at least a first period of time during which sampling is suspended due to the quality-aware feedback indicating that a level of movement of the user is sufficiently high to cause interference in the physiological sensing and a second period of time during which sampling is increased due to the polled contextual data indicative of the historically stressful context for the user; and
adjust a sampling frequency of a physiological sensor of the wearable device based on the adjusted physiological sampling schedule.
