  The Virtual Reality is basically made up of hardware and software components. Hardware components includes computer or VR engine and I/O devices whereas software components include application software and database. ·        Virtual Reality System Hardware   The major components of the hardware are the VR engine or computer system, input devices and output devices        I.             Input Devices   The input devices are the means by which th e user interacts with the virtual world. They send signals to the system about the action of the user, so as to provide appropriate reactions back to the user through the output devices in real time. They can be classified into tracking device, point input device, bio-controllers and voice device.
