Personal informatics has become a widespread practice, yet even expert users still face challenges in synthesizing and making sense of data. We suggest that these challenges are related to the complexities introduced once personal context is taken seriously. Through ethnographic research in the Quantified Self community, and an iterative software design process for a project called Data Sense, we offer early indications of what those challenges are, and describe how we approached solving them. We found that users had an easier time of working with data when they could use their own files, when temporal recurrences were surfaced and reminded them of other patterns, and when they could "grab" data directly from visualizations. However, the system did require more user learning than we anticipated.

La presente invention concerne des appareils, procedes et systemes pour une plateforme de fourniture de contenu gere par code comportant une interface de service de code graphique et un serveur d'informations declenche par un code ("GCSI/CTIS"). Le GCSI/CTIS connecte les symbologies d'encodage d'informations a des elements d'interface graphique, etendant ainsi le contenu d'informations utiles et l'interactivite d'affichages graphiques, des publicites, publications, diffusions et/ou autres. Les composants GCSI/CTIS facilitent une large gamme de fonctionnalites, y compris la formation de symbologies d'encodage robustes, la correction d'erreur, l'echantillonnage et l'achat de support, le reseautage social et les programmes de promotion des ventes.
