PolicyCraft: Supporting Collaborative and Participatory Policy Design through Case-Grounded Deliberation

A collaborative policy design system enabling participatory policymaking by anchoring discussions in concrete cases rather than abstract principles, using discussion and voting mechanisms. Field studies across two university courses demonstrated that students using PolicyCraft reached greater consensus and developed better-supported policies compared to control groups without case-based scaffolding. The research highlights how human-computer interaction design can bridge theoretical policy frameworks and real-world scenarios. Presented at CHI 2025.
