What is virtual reality, or VR?
什么是虛擬現實？
If something is virtual, then it is created by computer technology and appears as if it were real.

When you put on the headset, you look at two tiny television screens.
當你戴上這個頭戴式語音影像裝置，就會看見兩個小電視屏幕。
They are so close to your eyes that your mind will see the image as one picture, and you will believe that you have entered a different world.
它們離你的眼睛非常近，結果呈現在你腦海里的圖像在一個畫面上，從而使你覺得已經進入了另一個世界。
In many systems, you also wear a special data glove.
在很多系統內，你還要戴上特殊的數據手套。
With this glove you can reach out and touch things in the artificial world.
戴著這種手套，你就可以伸手去觸摸虛擬世界中的事物。
The first VR games, already sold round the world, enable you to drive a sports car, fly a plane, or fight an enemy.
