Data-driven Personal Cartographic Perspectives — An Overview of Applied, Artistic, and Academic Visualization Projects for Egocentric Retrospective Analysis of Personal Spatia-Temporal Behavior

With the continuing diffusion of Global-Positioning-System (GPS)-enabled technologies, the accumulation of spatio-temporal information is growing to unprecedented extends. Many use cases are centered around commercial data-driven services for citizens, companies, and government institutions, as well as academic research. Aside from these domains, a number of applications try to enable citizens to explore their own data, instead of merely using their data to drive a certain third-party service. This article investigates research projects and applications that explore such reflective practices on personal user-generated spatio-temporal data. The exemplars discussed in this paper all share the overall goal to provide users with new insights into their own spatia-temporal behavior.
