Classification: CPC A  G | IPC A  G

Claim 0:
1. A wearable device, comprising:
one or more sensors providing sensor output data comprising information about a user's physiological activity when the wearable device is worn by the user;
a display device; and
one or more processors configured to:
(a) operate the one or more sensors to provide the sensor output data when the wearable device is worn by the user;
(b) determine that a first portion of the sensor output data includes data indicative of the user being engaged in a first exercise activity;
(c) determine that a signal power of the first portion of the sensor output data is lower than a threshold;
(d) select, based on determining that the signal power is lower than the threshold, a first measure of a first periodic component of the first portion of the sensor output;
(e) update, responsive to the determination of (d), a physiological metric using information obtained from a frequency domain analysis of the first portion of the sensor output data;
(f) determine that a second portion of the sensor output data includes data indicative of the user being engaged in a second exercise activity;
(g) determine that a signal power of the second portion of the sensor output data is greater than a threshold;
(h) select, based on determining that the signal power of the second portion is greater than the threshold, a second measure of a second periodic component of the second portion of the sensor output;
(i) update the physiological metric using information obtained from a time domain analysis of the second portion of the sensor output data; and
(j) cause the display device to display the physiological metric.
