With simple tactile inputs and small e-paper visualizations, I/O Bits are dedicated physical devices that allow individuals to track and visualize different kinds of personal activities in-situ. This is in contrast to most self-tracking systems, which automate data collection, centralize information displays, or integrate into multi-purpose devices like smartwatches or mobile phones. We report findings from an e-paper visualization workshop and a prototype deployment where participants constructed their own I/O Bits and used them to track a range of personal data. Based on these experiences, we contribute insights and opportunities for situated and user-driven personal informatics.eng©ACM, 2021https://creativecommons.org/licenses/by/4.0Personal Data/TrackingVisualizationAmbient DevicesInternet of Thingsconference paperRGPIN2016-04564https://doi.org/10.1145/3461778.3462138
