Abstract
Physical activity trackers rely on fixed daily step goals, treating
the day as the primary unit for planning and evaluating activity.
However, these goals often misalign with everyday life: schedules
fluctuate, opportunities for movement vary, and long-term targets
can be difficult to sustain, leading to frustration and disengagement.
Despite growing evidence that short bouts of movement can meaningfully improve health, current systems provide limited support for
acting on these brief, situated opportunities. This paper investigates
micro-goals (i.e., brief, situated goals) as an alternative framing for
supporting physical activity. We developed Mikro, a smartwatch
app enabling on-the-go micro-goal setting, and deployed it in a
27-day field study with 16 participants. Our findings show that
micro-goals encouraged frequent tailoring, supported immediate
action, and helped participants capitalize on small opportunities
for movement. We argue that micro-goals can complement daily
step targets by scaffolding more flexible, adaptive, and engaging
ways of staying active.
