Virtual reality (VR) is a technology that creates a simulated environment, allowing users to experience and interact with a 3D space as if they were physically present. This is typically achieved through the use of a VR headset, which covers the eyes and often includes headphones for immersive audio. Users can look around and move within the virtual world, enhancing the sense of presence. VR is used in various fields, including gaming, education, and training. For example, medical professionals can practice surgeries in a risk-free environment, while gamers can explore fantastical worlds. This technology continues to evolve, offering new possibilities for entertainment and learning.
