VRTMS: A 3D-Virtual Reality Training and Maintenance System as a Modular Cognitive Approach to a Prototype Infrared Computed Tomography Machine Assembly

Training tools based on virtual reality (VR) are an up-and-coming solution in high-risk environments where practical and cognitive skills are vitally important and, at the same time, significantly cost-intensive. Presently, VR allows the most advanced simulation and comprehensive performance tracking, thus effectively supporting the practical training of personnel in the most complex and sensitive operations. The present paper aims to design and develop a VR training tool for the assembly of a prototype infrared computed tomography (CT) machine by providing users with high-precision, modular, and interactive components in a controlled virtual environment. The project implementation involved the wide-ranging use of tools, including Unity (runtime development), Visual Studio (integrated development), Blender (3D models’ creation), Substance Painter (texturing), Meta SDK (VR interaction), and AutoCAD for reference models. The augmented use of these tools resulted in creating a VR Training and Maintenance System (VRTMS), delivering highly optimized performance and overcoming the drawbacks of traditional training systems by providing an adaptive and immersive user experience. The tool enables the creation of a rich and user-friendly experience, crucial for training the employees in the assembly and maintenance procedures to impart precise enhancement in the skill development programs.
