Flexible Photorealistic VR Training System for Electrical Operators

Virtual reality can be a very effective tool for professional training, especially when training performed in reality would pose a high risk for the trainees. However, efficient use of VR in practical industrial training requires high-quality VR training environments - 3D scenes and interactive scenarios. Because creating such a VR environment is a complex and time-consuming task, existing VR training systems generally do not offer the flexibility that would allow trainers to adjust the environments to changing training contexts and requirements. In many cases, in industrial training, however, one can benefit from the componentization and repeatability of the training content to provide such flexibility. In this paper, we propose a method of creating photorealistic virtual reality training scenes with the use of a library of training objects. Designing training objects is a relatively complex process, but once a library of objects is available, a designer can assemble new training scenes from the objects available in the library. Training scenarios can be added using an easy-to-use graphical tool.
