I feel my wrist buzz. Smartbody and performative sensibility in Fitbit devices

Abstract This paper discusses the concepts of performative sensibility and smartbody. The central thesis is that performative sensibility highlights the instrumental nature of sensations in which objects act on the world. We show how the prescriptions of this new sensibility associated with wearables affect the body and subjectivity that we propose to call a smartbody. There were one hundred testimonials analyzed from the oldest thread with the greatest number of comments in the Fitbit user community forum. Quantitative tools and actor-network theory were used as a guide to assemble and analyze the corpus. The preliminary findings show that Fitbit users demonstrate particular changings in body care. Extreme behaviors, physical limits defined by system goals and quantification habits without utilizing the device are some of the examples found. These findings appear to indicate that the performative sensibility of wearables mobilizes new body performatic patterns and practices oriented by data.
