Designing Documentary Informatics

In this paper we describe a Research through Design inquiry about a speculative wedding documentation service, in the mode of the Quantified Self. We reflect on our design research, which included design ethnography, interviews, enactments of parts of the service, and the production of a concept brochure. In so doing, we explore the design of personal tracking as a documentary activity, one intended for longer-term self-expression and remembering -- rather than simply to monitor, regulate and motivate a data-driven life. Developing the Lived Informatics discourse, we use our design-led inquiry to propose \"Documentary Informatics\" as an alternative and longer-term design perspective on self-tracking tools.
