Virtual Reality

Definition:Virtual Reality is the technology that provides almost real and/or believable experiences in a synthetic or virtual way.

To achieve this goal, virtual reality uses the entire spectrum of current multimedia technologies such as image, video, sound and text, as well as newer and upcoming media such as e-touch, e-taste, and e-smell. To define the characteristics of VR, Heim [1] used the three ‘I’s, immersion, interactivity and information intensity.

• Immersion comes from devices that isolate the senses sufficiently to make a person feel transported to another place.

• Interactivity comes from the computer’s lighting ability to change the scene’s point of view as fast as the human organism can alter his or her physical position and perspective.

• Information intensity is the notion that a virtual world can offer special quality such as telepresence and artificial entities that show a certain degree of intelligent behavior.
