Abstract Navigation and situation awareness in 3D environments are often required by emergency responses such as firefighters, police, and military soldiers. This paper investigates a collaborative, cross-platform immersive system to improve the team navigation through effective real-time communication. We explore a set of essential building navigation, visualization, and interaction methods to support joint tasks in the physical building environments by leveraging on device sensors and image markers. Our platform also supports efficient exchange of useful visual information to improve the coordination and situation awareness for multiple users performing real-time operations in smart buildings. We have performed a user study to evaluate different devices used in coordination tasks. Our results demonstrate the effects of immersive visualization for improving 3D navigation and coordination for on-site collaboration in real physical environment.Graphical abstract
