Apparatus, methods, and computer programs for controlling use of sensor data

A method comprising:

• receiving sensor data of a user from a photoplethysmography (PPG) sensor located in an ear-worn device;
• determining signal quality of the received sensor data;
• comparing the determined signal quality to a quality threshold;
• if it is determined that the determined signal quality is greater than the quality threshold, providing the received sensor data to a first processing pipeline configured to determine at least pulse related biometric information;
• and
• if it is determined that the determined signal quality is less than the quality threshold, providing the received sensor data to a second processing pipeline, different from the first processing pipeline and configured to determine at least one of:
• user posture and movement related biometric information.

A non-transitory computer readable medium storing a computer program comprising instructions that, when executed by a processor, cause the processor to perform steps comprising:

• receiving sensor data of a user from a photoplethysmography (PPG) sensor located in an ear-worn device;
• determining signal quality of the received sensor data;
• comparing the determined signal quality to a quality threshold;
• if it is determined that the determined signal quality is greater than the quality threshold, providing the received sensor data to a first processing pipeline configured to determine at least pulse related biometric information;
• and
• if it is determined that the determined signal quality is less than the quality threshold, providing the received sensor data to a second processing pipeline, different from the first processing pipeline and configured to determine at least one of:
• user posture and movement related biometric information.
