We are members of a social-science laboratory in Sydney, Australia, and collectively we research how social factors, such as gender or education, affect health and how people integrate digital technologies into their everyday lives. We have studied topics including smartphone use, women’s health and fitness practices and how people use smartwatches to track self-improvement metrics. Observing people in their everyday environments was an important part of our work. Being physically present helped us to understand people’s routines and relationships, and the social world around them.
