Abstract:This thesis covers the design of a smartphone application which supports its users in making sustainable decisions while preparing their grocery lists. The Persuasive System Design model (PSD) by Oinas-Kukkonen & Harjumaa (2009) is used as a framework to analyze 25 behavior change systems from the domains of sustainable food consumption, food consumption and eco-feedback applications for energy & water consumption. It was found that the effects of Normative Influence and Personal Goal-Setting were not studied very much in the context of sustainable food consumption. A smartphone application was designed around these two novel system features, along with several other popular system features. The system was prototyped and a field study was conducted with 11 participants. The participants answered two questionnaires, one before the field study and one afterwards; while a subset of 8 participants were interviewed regarding their experiences with the application. A thematic analysis was conducted on the interview transcripts, while a statistical analysis was conducted on the questionnaire responses. Due to the low number of participants, the findings from the thematic analysis form the main findings of this work. Three main themes of motivation, effort and community emerged from the thematic analysis.
