This project develops a transformative AR/MR system that equips first responders with immersive, hands free interfaces for real time data integration during emergencies. Building on critical capability needs outlined in the DHS Project Responder 6 report, our research investigates how AR/MR technologies can be used with decentralized networking methods (e.g., isolated cellular and mesh networks) to create dynamic digital twins of disaster environments, enabling rapid decision-making. Rigorous simulation tools and iterative field feedback will be used to refine its functionalities. The anticipated outcome is a scalable, field deployable solution that improves response times and operational effectiveness, transforming emergency response and establishing a foundation for future innovations in human-machine interface design and resilient communications.
