VRML is a file format which allows user to access, navigate, Explore and interact with environmental data in

Wow systems are also known as desktop virtual reality, and they use monitors to display the virtual world. The screen is a window to the world, and designers try to make it as realistic as possible. Users may use specially designed input devices to interact with the virtual world that the computer monitor displays.
In this type an image of the user will be displayed into the computer program as a 2D computer character using cameras. As a result, the user will be fully immersed in the artificial world with real feelings of reality. However, one disadvantage is that the user will face some difficulty to interact with surrounding users.
Vidoe Mapping
Immersive V R
In this type the user will be completely & fully immersed in the virtual 3D environment. The user will be able to control & manipulate his virtual world by a realistic interaction with virtual objects using head mounted display, data gloves or other devices. The interacted user can look, touch, walk around or fly through capabilities & enhance his/her virtual experience by other non-visual technologies such as auditory. As a result, users will not be able to differentiate between the real world & their imaginary world.
