Tracking physical activity through biometric wearable technology has increased in popularity among both researchers and the lay public. The validity, accuracy, and reliability of many of these devices have been tested, but the results are frequently difficult to compare due to employment of different methodologies. Physical activity protocols and data validation techniques should be standardized in order to compare results across studies. This tutorial lecture will provide an overview of current biometrics, review industry standards in evaluating biometric devices, and best practices for working with devices, selecting participants, protocols, and test settings. The Consumer Technology Association (CTA) has recently published standards that outline protocols and validation criteria intended for evaluation of devices. This presentation from the SEACSM meeting in February, provides information necessary to unify the evaluation of devices for optimal decision-making and dissemination of data on consumer-based wearable devices, especially for typical metrics such as steps and heart rate. Additionally, this session discusses statistical analyses and provides an understanding of intrinsic complications during the research process with biometric wearable devices
