A virtual reality headset called the Oculus rift was produced by a company called Oculus VR. The Oculus Rift uses a 1080×1200 OLED panel for each eye. Headphones are also integrated to the device which makes the 3d effect more effective. The Rift has full 6 degree of freedom rotational and positional tracking. The tracking is carried out by Oculus’s Constellation tracking system which is very precise and submillimeter accurate. To control the Oculus Rift, a motion controller which is called the Oculus touch is available. It has joystick, buttons, and two triggers for grabbing or shooting.
