The allocation of knowledge should be decided depending on mutual superiorities of user (head) and product (world). 操作系统所需要具备的知识（能力），由用户和产品共同承担。知识的分配， 应该由产品和用户相互的优势而定。 Property 属性 Knowledge in the World 现实知识 Knowledge in the Head 大脑认识 Retrievability　可恢复性 Possible to search anytime if it is visual and oral. 有声有色的东西，总是很容易找到。 Hard to search. Should depend on the memory to search. 记忆中的东西不那么容易寻找。 Learning　可学习性 Needless to learn, just need to interpret the status of product. Depend on how to use the user mental model and limits. 无须学习，只需修改产品的参数。取决于如何利用用户的智力。 Much learning needed. If the learning is meaningful and well agree with user mental model, learning could be easier. 需要学习，如果学习是有意义的，并且与用户的智力模型相适应，学习将变得容易。 Efficiency of use　使用的效能 A bit slow because it is needed to understand and interpret the product information 有点慢，因为他需要理解并依照产品规则。 Effective, because it is needed to remember just once. 有效的，因为他只需要一次就能记住 Ease of use at first encounter 首次使用的易用性 Effective because beginners rely on the product information about the control. 非常有效的，因为初学者可以参照产品关于控制的说明。 Ineffective because beginners can’t remember the control information easily. 低效的，因为初学者不能轻松地记住所有的操作说明。 Aesthetics　美学的 Could be complex to indicate all the control information on the product itself. 产品本身可以通过复杂的设计显示所有的操作信息。 Use
