Spatial sharing in survey meter training utilizing mixed and augmented reality

Recent developments in immersive tools for radiation-related training have been notable. However, these training programmes have primarily been developed from a first-person perspective, often limiting the sharing of the training experience. This study developed a tool that facilitates real-time spatial sharing of training using mixed reality (MR) and augmented reality (AR). Our MR system, which wirelessly connected HoloLens 2 with a survey meter mock-up, enabled the visualisation of radiation and simulated a detector's response. It also shared training information every second via a WebSocket server. Concurrently, the AR system allowed observers, equipped with an AR tablet, to view the MR operator's status in real time based on this shared data. Post-training, the shared data were saved as text, enabling reflective learning through visualisation. We anticipate that this tool would significantly enhance the efficiency of survey meter training without radiation exposure.
