- HomeTree: an art inspired mobile eco-feedback visualizationPublication . Quintal, Filipe; Nisi, Valentina; Nunes, Nuno; Barreto, Mary; Pereira, LucasThis paper presents HomeTree a prototype of an art-inspired mobile eco feedback system. 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.
- SINAIS from Fanal: design and evaluation of an art-inspired eco-feedback systemPublication . Nisi, Valentina; Nunes, Nuno Jardim; Quintal, Filipe; Barreto, MaryIn this paper we present the challenges exposed during the designing, implementing and assessment of a novel eco feedback system resulting from the intersection of human computer interaction (HCI), and Digital Art. We explore how a digital art mode of inquiry can contribute to expose existing challenges in eco-feedback technology. Our new art inspired eco-feedback visualization, maps electricity consumption to effects on natural elements of the local natural landscape. The feedback was piloted with eight local families for four weeks. Reactions of the users were assessed through interviews and quantitative measures. Our findings showed that users found the mapping of the eco feedback to artistic representations of elements of the natural environment somehow compelling, despite lacking of clear quantitative information. In conclusion, the conducted study provide useful findings and insights into future deployment of eco-feedback using artistic visualizations, information visualization and motivating behavior change.
