  • 3. Overview Goal First explore the role of self-shaping in the minds of expert users Identify how they use self-shaping Provide a framework for explaining different kinds of self- shaping !

  • 9. Three formative studies Study 1: Self-tracking to behavior change ! Study 2: User-generated self-shaping designs ! Study 3: Features that support self-shaping !
  • 10. > Study 1: Self-tracking to behavior change Goal identify how expert users see the role of self-shaping in the tools they use ! Web-based survey participant 18 Quantified Self interest group, 5 비전문가 (30.5세, 여성 13명) ! 행동 변화에 툴(e.g. food diaries, pedometers)을 사용함으로 self-discipline의 요구가 높 아졌는지 낮아졌는지 질문 ! 7점 likert scale(1: no self-discipline) Self-discipline required to implement a desired behavior: 4.4 (SD=0.8) With the right tool, 3.4 (SD=0.9) ! Self-discipline is required regardless of tool use
  • 11. > Study 2: User-generated self-shaping designs 41 experts posted 65 self-shaping designs on website. ! Self-shaping ability/paths force myself to, make it easier to, make it harder to, so I can’t, Self-shaping triggers remind, attention, tells me to Self-shaping motivation force myself to, guilt me, motivate me, look forward
  • 12. > Study 2: User-generated self-shaping designs ! Result 1. The practice of self-shaping is a function of the individual, not the tool or technology ! Result 2. The clearer the intention of a future concrete behavior is, the more personalized the self-shaping design was. ! Result 3. Salience of self-shaping features differs greatly between tools (computer printer / alarm clock) ! Result 4. Tools vary widely in how flexible their self-shaping use is (online calendar / pedometer)
  • 13. > Study 3: Features that support self-shaping Reviewed 67 tools ! Flexible Appliances Flexible Self-shapers Fixed-use Appliances Fixed-use Self-shapers
