Eco-Garden: Fostering Sustainable Practices Through a Data Sculpture to Reduce Household Consumption
摘要
As sustainability becomes an urgent global priority, systems that support consumption reduction in households are essential. We present the design and development of Eco-Garden, a data sculpture and a companion mobile app, that visualises household consumption for electricity, gas, and food waste. Eco-Garden was developed through a four-phase, human-centered design process, incorporating insights from participants including goal-setting, peripheral interaction, aesthetics, and child-friendly features. While the sculpture delivers intuitive feedback, fostering awareness through subtle visual cues without demanding constant attention, the mobile app allows for detailed tracking and goal-setting. Positioned in shared spaces in households, the sculpture encourages sustainable practices as a whole-household effort. We report findings from a three-week field study with 15 households that suggest that the constant physical presence and feedback of Eco-Garden supported an ongoing awareness of consumption and motivated shifting practices through clear and achievable goals. This study contributes to eco-feedback research by demonstrating the impact of physical feedback in households.
