An environment can be created by the use of technology, which appears to be real and can touch objects but cannot be able to feel it. Three primary categories of virtual reality are non-immersive, semi-immersive, and fully-immersive simulations. The equipment used to create virtual reality is head-mounted displays (HDMs), immersive rooms, datagloves, and wands. They help in improving knowledge retention, improve attentiveness and reduce training time, increase reaction time and decision-making skills, and develop soft skills.
