Classification: CPC A | IPC A

Claim 7:
8. A non-transitory computer-readable medium having stored thereon instructions executable by at least one processor to perform operations comprising:
receiving, from a wearable device using a communication interface, an indication of a motion-compensated cardiovascular signal generated by the wearable device by (i) detecting, using a photoplethysmographic sensor of the wearable device, a photoplethysmographic signal related to cardiovascular activity of a user, (ii) detecting, using a motion sensor of the wearable device, a motion signal related to motion of the user, and (iii) using the motion signal to generate the motion-compensated cardiovascular signal based on the photoplethysmographic signal;
receiving, from the wearable device using the communication interface, an indication of the motion signal;
generating a corrected heart rate that has been generated, based on the received indication of the motion-compensated cardiovascular signal and the received indication of the motion signal, by the one or more processors using an algorithm informed by at least one statistical prior for pulse rate transitions between activity states to generate one or more probable pulse paths and using the one or more probable pulse paths to generate the corrected heart rate; and
transmitting, using the communication interface, an indication of the corrected heart rate to the wearable device.
