A low-cost distributed iot-based augmented reality interactive simulator for team training

The performance over cost ratio of last generation off the shelf devices enables the design of heterogeneous distributed computing systems capable of supporting the implementation of an immersive Virtual Reality, Internet of Things based training support architecture. In this paper we present our work in progress on a low cost distributed immersive simulation system for the training of teams by means of Virtual Reality and off the shelf mobile and prototyping devices. In this case, performance prediction is crucial, because the generation of the scenario have to be performed in real time and synchronization problems may disrupt the result. The approach is demonstrated by a prototypical case study, that consists in a distributed simulator for the interactive training of groups of people that have to coordinate to face a fire emergency, and features advanced immersivity thanks to CGI-enabled stereoscopic 360 degree 3D Virtual Reality and ad-hoc devised interaction interfaces. In particular, we focus on the subsystem that is related to a single trainee, providing a reference implementation and a performance evaluation oriented model to support the design of the complete system.
