Definition of Virtual Reality (VR)


   Virtual reality is a realistic simulation of an environment, including three- dimensional graphics, by a computer system using interactive software and hardware. The user wears a headset that contains two screens-one in front of each eye. The brain combines the screen images to create a three-dimensional (3D) scene. The headset plays stereo sounds-one into each ear-which the brain combines for a surround-sound effect. In addition, many systems make use of gloves, shoes and even whole suits with sensors to detect the user’s movement. It is mainly used in entertainment arts, business, communication, design, education, engineering, medicine and many other fields.
