The focus groups were guided by semi-structured interviews, whereas participants interacted with 4 common consumer activity tracking devices (Fitbit Inspire 3, Apple Watch SE, Polar Watch, Oura Ring Heritage). Audio recordings were analyzed using the Rapid Identification of Themes from Audio Recordings method. Participants ranked each device based on comfort, convenience, and features (eg, tracked outcomes of activity, distance\/GPS, and respiratory rate).
