Architecture for Virtual Reality Disaster Response Training System
with Six degrees of Freedom (6 DoF)
Scope:
This standard defines the reference architecture needed to implement a virtual reality training system that can simulate responses to possible disasters in large physical spaces. This reference architecture should include the physical-to-virtual component that transfers sensor data in the large space to the virtual world, the virtual-to-virtual component that conveys the data between virtual world objects, and the virtual-to-physical component that transfers the simulated responses in the virtual world to actuators in the physical world.
Need for the project:
So far, virtual reality-based training systems have had limitations in perfectly transferring real experiences into virtual reality. Significant national, economic and social losses from recent disasters have been caused by improper disaster response. In order to reproduce a disaster situation that is difficult to realize in reality, a “disaster response virtual training system in large space” is required. The digital twin in a disaster situation detects the physical amount of the user’s or object’s location, speed, and acceleration in the real world and tracks their movements and postures. The system then reflects and coordinates the movement and posture of the virtual world objects. It is also important to synchronize the sensorial effects in the virtual world (e.g., visual and auditory effects) and physical sensorial effects (e.g., tactile and olfactory effects) simultaneously. As there is no architecture standard for realizing such a disaster response virtual training system for large space, so the manufacturers rely on the proprietary system architectures and specifications provided by individual service providers. The reference architecture of the disaster response virtual training system for large spaces can lead to the development of industries related to the virtual training system, and is expected to contribute to disaster preparedness and public safety through effective disaster response training.
