BinCam



BinCam is a social persuasive system to motivate reflection and behavioural change in the food waste and recycling habits of young adults. The system replaces an existing kitchen bin and automatically logs disposed of items through images captured by a smart phone installed on the underside of the bin lid. Captured images are uploaded to a BinCam application on Facebook where they can be explored by all users of the BinCam system.

BinCam was deployed in three user studies that each were spanning over a period of 4-6 weeks and involved a total of 93 students who were living in 16 shared households. A number of changes were made to the BinCam system and its evaluation following the first study to foreground, in the second study, the use of gamification elements in the design, improve the waste logging accuracy, and align the evaluation criteria more closely to established models and theories of behavioural change; and, in the third study, to explore potential inter-cultural differences in recycling and food waste behaviours as well as barriers.




Engagement with BinCam was designed to fit into the existing structure of users’ everyday life, with the intention that reflection on waste and recycling becomes a playful and shared group activity. Results of our studies revealed increases in both users’ awareness of, and reflection about, their waste management as well as their motivation to improve their waste-related skills. With BinCam, we also explored informational and normative social influences as a source of change (e.g., socially evoked feelings of ‘guilt’ for non-recycling or food disposal).
