The headset tracks the movement of your head and changes the images shown on the display according to the movement. This process creates the sensation that users are located within the virtual environment. Users of these gadgets are able to interact with the virtual environments. Various input methods, from the traditional game controllers and keyboards to the futuristic hand gestures and voice commands, are available or under development.
