Virtual Reality

Essentially, virtual reality systems consist of the computer and software—known as the reality engine—input sensors, and output sensors. The input sensors are the equipment to computer enthusiasts, and include the keyboard, mouse, knobs, and joysticks. Output devices include the printer and the video display monitor. In addition, virtual reality input and output devices include the head- and ear-mounted equipment mentioned above, and gloves for controlling the virtual world. Finally, the fourth sensory component is the user, who both directs and reacts to the chosen environment.
