Techniques for optimal parameter tuning for a wearable device

A wearable device, comprising:

• one or more light-emitting components configured to emit light into a tissue of a user;
• one or more photodetectors configured to receive the light emitted by the one or more light-emitting components;
• and
• one or more processors configured to control the one or more light-emitting components and the one or more photodetectors, wherein the one or more processors are individually or collectively configured to:
• acquire first photoplethysmogram (PPG) data from the user during a first measurement interval using an optical channel of the wearable device, the optical channel comprising a light-emitting component from the one or more light-emitting components and a photodetector from the one or more photodetectors, wherein the first PPG data is acquired in accordance with a first measurement profile;
• determine that a quality of the first PPG data acquired in accordance with the first measurement profile fails to satisfy a quality threshold;
• acquire second PPG data from the user during a second measurement interval using the optical channel of the wearable device, wherein the second PPG data is acquired in accordance with a second measurement profile based at least in part on the quality of the first PPG data failing to satisfy the quality threshold;
• and
• transmit the second PPG data to a user device to support determination of one or more health-related metrics associated with the user based at least in part on the second PPG data.

A wearable ring device, comprising:

• a housing that is configured to at least partially surround a finger of a user, the housing comprising an inner surface that is configured to contact the finger of the user;
• one or more light-emitting components disposed within or beneath the inner surface of the housing, the one or more light-emitting components configured to emit light into a tissue of the user;
• one or more photodetectors disposed within or beneath the inner surface of the housing, the one or more photodetectors configured to receive the light emitted by the one or more light-emitting components;
• and
• one or more processors configured to control the one or more light-emitting components and the one or more photodetectors, wherein the one or more processors are individually or collectively configured to:
• acquire first photoplethysmogram (PPG) data from the user during a first measurement interval using an optical channel of the wearable ring device, the optical channel comprising a light-emitting component from the one or more light-emitting components and a photodetector from the one or more photodetectors, wherein the first PPG data is acquired in accordance with a first measurement profile;
• acquire second PPG data from the user during a second measurement interval using the optical channel of the wearable ring device, the second measurement interval subsequent to the first measurement interval, wherein the second PPG data is acquired in accordance with a second measurement profile;
• select the first measurement profile or the second measurement profile based at least in part on a comparison of respective measurement quality metrics, respective power consumption metrics, or both, associated with the first measurement profile and the second measurement profile;
• acquire additional PPG data during a third measurement interval using the optical channel and in accordance with one of the first measurement profile or the second measurement profile based at least in part on the selecting;
• and
• transmit the additional PPG data to a user device to support determination of one or more health-related metrics associated with the user based at least in part on the additional PPG data.
