THE APPLE WATCH

The Apple Watch includes a feature to measure blood oxygen levels of the wearer. The watch employs optical sensors to capture health-related data --using light to detect blood flow through the skin.

The suit alleged algorithm training sets and calibration processes inadequately considered variations in skin tones, leading to inaccurate readings; particularly for individuals of certain racial backgrounds.

Apple's technical response involved a comprehensive review of the optical sensor calibration and algorithmic training processes. The company worked closely with experts in data science and health technology to refine the algorithms, ensuring they were more inclusive and provided accurate readings across a diverse user base; ultimately improving the overall prevision and reliability of the Apple Watch for its customers.

Apple’s case underscores the necessity for addressing potential sources of data bias (e.g. convenience samples) in the algorithm development cycles, especially when the algorithm will be used with diverse populations.
