Virtual reality (VR) influences training and simulation by providing immersive experiences that replicate real-world scenarios. In sectors like healthcare, military, and education, VR allows users to practice skills in a safe environment, enabling them to make mistakes and learn without real-world consequences. This method enhances engagement and retention of knowledge, as learners can visualize and interact with the material. VR simulations can also be tailored to specific training goals, offering personalized feedback that can lead to better outcomes and preparedness in high-stakes situations.
