However, while some users derive value from their trackers for a long time, others find barriers to incorporating this technology into their routines. Using an online survey focused on both ex-users and current users of activity trackers, this study investigated factors of discouragement and reasons that could contribute to long-term adoption. Subsequent interviews with a sample of ten participants were conducted to approaches, the findings of this study suggest that long-term use is derived from the positive difference between the sense of usefulness and the effort necessary to maintain the continuous use of the devices. Acknowledgments I wish to express my sincere gratitude to Dr. Vicki Hanson, committee chair, Distinguished Professor, for guidance and for all the opportunities to introduce me in the research field. I also thank Dr. Hugo Nicolau, committee member, for orientation and openness to share, and for being my inspiration to work on research. My sincere gratitude to Dr. Matt Huenerfauth, committee member, Associate Professor, for all detailed comments and time dedicated to support me during my graduate program. I also thank Jill Pearson, Graduate Academic Advisor, for all support during my stay in this institution. And finally, I would like to thank CAPES/CNPq for funding my master program under the Brazilian Scientific Mobility Program (Ciencia sem Fronteiras), process number 88888.076031/2013-00.
