In June 2009 we collaborated with the Centre for Food Policy in the School of Community and Health Sciences at City University to develop an online micro-module on sustainable development. The aim of the module was to introduce the subject of sustainability to all University students and staff members. We approached this design task by carrying out various user research activities, which led to a number of conceptual prototypes before the final design was chosen and implemented. Discussions with the stakeholders led us to focus on the undergraduate students as our main target audience early on in the process. This presentation lists the sustainability related interactive applications we came across during the research stage of the project.
