Virtual Reality Design Features That Impact the Efficiency and Accuracy of Electrical Workforce Training Scenarios

Workplace safety, particularly electrical hazards, is crucial in the construction industry, with electrical issues among the top causes of construction fatalities. Energy storage systems (ESS) and microgrids pose significant risks to workers lacking proper knowledge of large-scale batteries. Virtual reality (VR) has proven to be effective in improving specific knowledge and skills in various domains and has demonstrated potential for effective training, especially when access to ESS facilities is limited. To achieve educational effectiveness comparable to hands-on training, VR modules must consider specific design features. This study assessed an immersive VR module for training electrical workers in battery assembly and connection. Participants completed identical tasks twice: once in VR and once with physical components. Researchers recorded and analyzed participants' behavior, comparing the efficiency of VR and physical training through video coding analysis to identify crucial VR design features impacting educational effectiveness. While physical training currently demonstrates greater accuracy and efficiency, there is potential for VR training to improve through focused design enhancements. Addressing challenges and implementing design improvements will enhance VR training's value across diverse fields.
