See what I mean? A voice-controlled system may have no windows but neither do telephone voice-response systems ("press 6 if you hate voice mail," and so on), and they have hellishly bad interfaces. Just because it isn't a Mac or doesn't have Windows does not mean it has no "interface." The way you accomplish tasks with a product, what you do and how it responds - that's the interface. (查看原文)
In current desktop-based systems, you must always navigate to the task. This is the same as the worst case for an interface that always returns you to what you were last doing, because in the case of wishing to return to the task from which you left off, you have to do no work at all. (查看原文)

This can be achieved only on the rare occasions when the original interface has some major flaw that is remedied by a minor fix. (Parts of this section are based on Raskin 1994.) (查看原文)
An interface, as far as is possible, should be self-teaching. This does not mean that an interface is, or can be, intuitive but that a user can readily find comprehensible explanations or instructions when she needs them.

Many computer owners find themselves also purchasing sex-changing adapters because adapters are smaller and less expensive than cables. For example, say you own only male-to-female cables but you need to connect two devices that both have female connectors. (查看原文)
