We introduce DayClo, an interactive clock visualizing schedule data for supporting users to reflect and self-track themselves in their daily lives. DayClo is designed by applying the form and time representation method of analog clocks. It shows the user's upcoming schedules through the sequential movement of two clock hands with hidden LEDs and a display. We deployed DayClo in eight participants' working spaces for a month to explore how the design and its interaction could support their reflections on their scheduling practices. The findings revealed that DayClo supported users' casual access to the schedule data and motivated self-tracking of their plans. Moreover, the moving clock hands revealed the empty time of their schedules and helped to draw new plans for their implicit goal. Our findings suggest new opportunities for designing everyday objects as a medium of delivering and fostering spontaneous interaction with personal data for self-reflection.
