Spatial sharing in survey meter training utilizing mixed and augmented reality

Area of Science:

• Medical Physics
• Virtual Reality in Education
• Radiation Safety Training

Background:

• Immersive tools for radiation training exist but often lack shared experiences due to first-person perspectives.
• Current radiation training methods may have limitations in collaborative learning and real-time feedback.
• Sharing training experiences is crucial for effective skill development in radiation safety.

Purpose of the Study:

• To develop and evaluate a mixed reality (MR) and augmented reality (AR) tool for real-time spatial sharing of radiation survey meter training.
• To enable collaborative learning and reflective practice in radiation safety training.
• To enhance the efficiency and accessibility of survey meter training.

Main Methods:

• Developed an MR system using HoloLens 2 connected to a survey meter mock-up for radiation visualization and detector response simulation.
• Implemented real-time data sharing via a WebSocket server every second.
• Created an AR system for observers using tablets to view the MR operator's status and training data.

Main Results:

• The MR system successfully visualized radiation and simulated detector responses.
• Real-time spatial data sharing between MR and AR systems was achieved.
• Saved training data facilitated post-training reflective learning through visualization.

Conclusions:

• The developed MR/AR tool facilitates real-time spatial sharing of radiation survey meter training.
• This technology enhances collaborative learning and reflective practice in radiation safety.
• The tool offers a promising, efficient, and radiation-free approach to survey meter training.
