Virtual reality (VR) has emerged as a disruptive technology with great potential to transform various fields, including industrial training. In the water packaging industry, where accuracy and safety are critical, VR provides a unique opportunity to optimize efficiency and quality in worker training. This study set out to evaluate the effectiveness of a VR-based training system compared to traditional methods, with a focus on the acquisition of knowledge and skills in the bottled water packaging process. The study demonstrated that VR is a highly effective tool for training in industrial settings. Comparing VR training with conventional methods in a water bottling process, an experimental group was formed using VR, while a control group received traditional training. The results revealed that participants in the experimental group achieved significantly higher performance on a post-test of knowledge (94% vs. 61% of the control group). In addition, the VR system usability evaluation showed high user acceptance, with an average score of 72.85 on the SUS (System Usability Scale). These findings suggest that VR has the potential to revolutionize job training, offering more immersive and effective learning experiences.
