This survey was completed in the summer of 2009. Here is a transcript of the survey.
The survey helped us develop a stage-based model of personal informatics systems. The model is a series of five stages (Preparation, Collection, Integration, Reflection, and Action) with four properties: problems in earlier stages cascade to later stages; stages are iterative; they are user-driven and/or system-driven; and they are uni-faceted and/or multi-faceted. From these properties, we suggest that personal informatics systems should 1) be designed in a holistic manner across the stages; 2) support iteration between stages; 3) apply an appropriate balance of automated technology and user control within each stage to facilitate the user experience; and 4) provide support for associating multiple facets of people's lives to enrich the value of systems.
