Urban planning decisions shape cities for decades, yet citizen engagement remains PDFs, public hearings, and comment forms — processes that reach only the most motivated, most vocal residents. The majority never engage, not because they don’t care, but because the mechanism doesn’t meet them where they are. XR changes the proposition entirely: instead of asking residents to imagine a proposal from a floor plan, you place it at full scale in the actual location through their phone. Feedback becomes spatial, immediate, and accessible to anyone who happens to walk past — not just those who attend a council meeting.​

​

Which planning proposal types benefit most from spatial XR presentation, and what fidelity level is actually needed to support meaningful feedback? How should a planner without 3D or development skills publish a proposal, anchor it to a location, and manage the feedback it generates? What feedback mechanisms work in XR — open text, spatial annotation, structured rating — and how are outputs structured for practical planning team use? ​

​

We are looking to develop a functional web AR demo covering both the planner publishing flow and the citizen feedback experience, demonstrated on at least one real or realistic planning scenario.​
