Virtual Reality-Based Disaster Communication System Using Redirected Walking Algorithms

Virtual Reality (VR) represents a significant advancement in human-computer interaction, offering diverse applications across various domains. One of its critical uses is in disaster response and rescue operations. During floods and other natural calamities, traditional communication methods often fail due to network disruptions and physical barriers. This paper proposes a VR-based system to facilitate communication between rescue teams and affected individuals when conventional methods are unavailable.The system incorporates Redirected Walking (RW) algorithms, which predict human motion to guide users within a virtual environment without exceeding physical boundaries. Unlike simple waypoint-based models, our approach provides a realistic representation of user behavior, improving navigation and interaction. The system is designed to work within various virtual and physical environments, allowing for real-time evaluation under dynamic conditions.A key feature of the proposed system is a projection-based communication mechanism, where rescue teams project messages from helicopters to designated ground locations. When individuals step into these specified zones, they receive crucial information, enabling effective communication and coordination during rescue missions. This innovative use of VR enhances disaster management efforts, ensuring better reach and responsiveness in crisis situations
