The CHANGE project was a collaboration between Goldsmiths, Nottingham University, Sussex University and The Open University. We investigated how technologies can provide insights into, and potentially change, patterns of human behaviour, especially those that have an impact on the environment. It was funded by an EPSRC grant that ran from November 2009 to July 2011.

We focused on situated decision-making and explored ways of providing people with information that would nudge their behaviour. We employed two techniques: first, making relevant information salient; and second, showing participants how their behaviour compared to other people in their social group.

In the Tidy Street project we combined web technologies with a large scale display sprayed on the road to make people more aware of their electricity usage and how it compared to other households in Brighton, UK.

The video below gives an overview of the Lambent Shopping Trolley Handle, a novel display technology that we developed to make product information more salient to supermarket shoppers and also show them how the contents of their trolley compared to other shoppers (for example, if the average food miles of the items of the items they had selected was higher or lower than the norm).

More information about the Lambent Shopping Trolley Handle and the Tidy Street project can be found on the projects page and papers downloaded from the publications page. You can also download the slides from a 2011 talk that gives an overview of both projects and the nudge techniques used.
