For example, in the first-person shooter genre of games (see below), players usually employ the mouse to control the direction in which the virtual player's "head" faces: moving the mouse up will cause the player to look up, revealing the view above the player's head.
例如，在第一人称射击类游戏（见下文）中，玩家通常会使用鼠标来控制虚拟角色的“头部”所朝向的方向：向上移动鼠标会让角色抬起头，露出角色头部上方的视角。
