This research examines collective contexts where data tracking and sensemaking practices may be socially motivated, collaboratively conducted, or otherwise extend beyond the single-user assumptions of typical personal informatics tools. Given graphical metaphors can be more familiar, relatable, and therefore meaningful to users as well as provide privacy-sensitive abstraction of data, we are also designing media representations for personal devices and public displays to explore questions around flexible interpretation, social connectedness, and data ephemerality.
