Virtual Reality

Virtual reality (VR) refers to computer-generated environments or realities that are designed to simulate a person’s physical presence in a specific environment that is designed to feel real. The purpose of VR is to allow a person to experience and manipulate the environment as if it were the real world. The best virtual realities are able to immerse the user completely. Virtual reality should not be confused with simple 3-D environments like those found in computer games, where you get to experience and manipulate the environment through an avatar, rather than personally becoming part of the virtual world (Source: www.techopedia.com)
