I partnered with colleagues in departments of Kinesiology and Health Education and Communication Studies at the University of Texas to explore wearable fitness devices from a communication perspective. Although studies have investigated how the technical features of wearable fitness trackers promote physical activity, we understand less about how communication surrounding such devices may contribute to their success. Our findings, which you can read here, show how and with whom people communicate fitness tracker messages and explains the effects of sociomaterial practice on interactions between wearable fitness device users.
