Automated Online Process Training in a Virtual Environment

In this paper, we present the framework for an online virtual reality based learning environment for automated process training. The system has a lecture component that uses text-to-speech narrated lectures that are synchronized with interactive 2D and 3D graphics to introduce students to the concepts they will train on. The system also has a virtual environment (VE) that students navigate, in first person, where the practical training takes place. The VE contains accurate graphical models of the equipment on which training is sought, and is programmed with the logic of how the equipment is operated, and how it behaves. The system was used in various applications including training in the operation of Computer Numeric Control (CNC) milling and turning machines, welding machines, and industrial centrifugal pumps. In a pedagogical study that was done on the system, it was found that the virtual reality enhanced interactive online training produced similar student outcomes as compared to the traditional classroom lecture/lab approach.
