A Gamified Dashboard for Sustainable Healthy Food: Design of Group Behavior Incentives and Social Collaboration

摘要

With growing attention to sustainability and public health, helping people adopt healthier, eco-friendly diets in daily life remains challenging. Most digital health tools focus on individual tracking and lack long-term incentives and social interaction, leading to low engagement and limited behavior change. This study proposes “GreenEat Family,” a gamified dashboard that integrates group-based incentives and social collaboration to help families and communities improve dietary health and sustainability together. We built a dual-index food database (Health & Nutrition Index; Environmental Impact Index) and designed an incentive system using virtual rewards (“GreenLeaves”) and achievement badges. Social features—including family challenges, community leaderboards, and experience sharing—enhance belonging and collective motivation. In an 8-week study (N=92), compared with a traditional tracking app, the experimental group showed higher sustainable diet knowledge (p<0.01), improved diet health index (+18.5%, p<0.05), and reduced negative environmental impact (−22.3%, p<0.05), with significantly greater usage frequency and duration, indicating strong potential for sustained behavior change.
