Heart rate correction
First Claim
1. A computing device, comprising:
- a hardware sensor interface configured to receive a machine-readable heart rate signal and a machine-readable wearer activity signal describing one or more aspects of a current activity of a wearer of the computing device; and
a heart rate reporting machine configured to;
estimate a first candidate heart rate of the wearer based on the machine-readable heart rate signal using a first heart rate estimation approach;
estimate a second candidate heart rate of the wearer based on a frequency domain transformation of the machine-readable heart rate signal using a second heart rate estimation approach different than the first heart rate estimation approach; and
output the first candidate heart rate when the first candidate heart rate is more consistent with the machine-readable wearer activity signal than the second candidate heart rate;
oroutput the second candidate heart rate when the second candidate heart rate is more consistent with the wearer activity signal than the first candidate heart rate.

Abstract
A wearable heart rate monitoring device includes an optical sensor configured to translate test light reflected from a wearer of the wearable heart rate monitoring device into a machine-readable heart rate signal. The wearable heart rate monitoring device also includes a motion sensor configured to translate motion of the wearable heart rate monitoring device into a machine-readable motion signal. The wearable heart rate monitoring device also includes a heart rate reporting machine, configured to determine a type of activity currently being performed by the wearer of the wearable heart rate monitoring device based at least in part on the machine-readable motion signal, and output an estimated heart rate based on at least the machine-readable heart rate signal and the type of activity.
