Emotional responses to a product can be critical in influencing how the product will be used. This study explores the emotions that arise from users' interaction with eco-feedback products, and investigates links between emotions and users' resource conservation behaviors. In-lab experiments were conducted with 68 participants of varying backgrounds. Each participant was shown sketches of four conceptual designs of eco-feedback products and reported how they would feel and behave in different scenarios using the products. Two styles of eco-feedback design, quantitative and figurative, were compared to each other and were compared to neutral designs, which had little or no feedback information. Results showed that taking resource conservation actions such as turning off lights was highly correlated with negative emotions toward wasting resources, such as guilt, upset, embarrassment, and annoyance. Users' evaluations of esthetics, usefulness, and overall quality of eco-feedback products, however, were highly correlated with positive emotions toward resource conservation, described as satisfied, proud, interested, and joyful. Figurative designs were observed to evoke much stronger emotions among younger participants than older ones. Ultimately, we hope our findings are useful to the designers of eco-feedback products.
