直接操纵

Direct Manipulation

Direct manipulation means that people feel they are controlling something tangible, not abstract. The benefit of following the principle of direct manipulation is that users more readily understand the results of their actions when they can directly manipulate the objects involved.

直接操纵意味着人们觉得他们都在控制切实的而不是抽象的东西。遵循直接操纵的原则的好处是，用户更容易了解他们的操作对于操纵对象所产生的结果。

iPhone OS users enjoy a heightened sense of direct manipulation because of the Multi-Touch interface. Using gestures, people feel a greater affinity for, and sense of control over, the objects they see on screen, because they do not use any intermediate device (such as a mouse) to manipulate them.

因为其多点触摸界面，iPhone 操作系统的用户享受着高度的直接操纵的愉悦感受。使用手势操作让用户对他们在屏幕上看到的对象，感觉上更具亲和力，和控制感，因为他们不必使用任何中间设备（如鼠标）操纵它们。

To enhance the sense of direct manipulation in your iPhone application, make sure that:

为了提高你的 iPhone 应用程序中的直接操纵感，请确保：

• Objects on the screen remain visible while the user performs actions on them

当用户对在屏幕上的对象执行操作时，要保持他们可见

• The result of the user’s action is immediately apparent

用户的操作结果是立即地显而易见
