HomeTree: an art inspired mobile eco-feedback visualization. In International Conference on Advances in Computer Entertainment Technology (pp. 545-548). Springer, Berlin, Heidelberg.

The system is implemented on a tablet PC and relies on a non intrusive energy-monitoring infrastructure to access consumption and power event information. Our prototype addresses an important problem in eco feedback, which is the fact that users loose interest about their energy consump tion after a period of several weeks. To accomplish this HomeTree implements a dual visualization strategy. Initially HomeTree presents users with a screensa ver that shows energy consumption mapped in a dynamic illustration of the lo cal forest. Through this strategy we leverage the emotional connection between the short-term energy consumption and the long-term effects on nature through the local depicted landscape. In a second mode of operation users can interact with HomeTree directly by checking the historical records of their consumption data, and check which days or weeks they have reduced or increased consump tion. Furthermore a comparison with a more objective baseline, such as the city of Funchal energy consumption is provided, in order to give users a sense of the level of their consumption in a wider context.engAffective computingSustainabilityAestheticsArt driven eco-feedbackUser interfacesPrototyping.Faculdade de Ciências Exatas e da EngenhariaFaculdade de Ciências da VidaEscola Superior de Tecnologias e Gestãoconference object10.1007/978-3-642-34292-9-55
