Virtual and augmented reality (VR and AR) revolutionize training and simulation by creating immersive, realistic environments for skill development and practice. In VR, users experience fully virtual scenarios, ideal for high-risk professions like aviation or surgery, where trainees can safely practice procedures. AR overlays digital information onto the real world, enhancing on-the-job training by providing real-time guidance and feedback. Both technologies improve learning retention, reduce training costs, and allow for scalable, customizable training solutions across various industries, ensuring a highly effective and engaging training experience.
