program visualizer的用法和樣例：
例句
- Perhaps sensing my ineptitude, the program generated a second shooter who appeared on my display as a flickering soldier.
也許感應到我的笨拙，於是程式送來了另一名射擊手，我的顯示器上出現了一名忽隱忽現的士兵。 - Rather than the one-way cycle of information from the keyboard to the program to the video display, the user directly interacts with the objects on the display.
用戶直接和顯示器上的對象交互，而不僅僅是從鍵盤到程序再到視頻顯示器的單一方向的信息循環。
