Make labels short, plainly worded, and quick to read. (This includes menu items, buttons, links, and anything else identified by text.) They'll be scanned and guessed about; write them so that a user's first guess about meaning is correct. If he guesses wrong several times, he'll be frustrated and you're both off to a bad start.
为扫描而不是阅读。精简文字。 -
Use the layout of the interface to communicate meaning.
用布局排版来传递信息。 -
Make it easy to move around the interface, especially for going back to where a wrong choice might have been made hastily.
提供良好的导航系统。 -
Keep in mind that a complicated interface imposes a large cognitive cost on new users. Visual complexity will often tempt nonexperts to satisfice: they look for the first thing that may work.
一定要记住复杂的界面强迫新用户花费大量学习成本。 - Don't accost the user with too many upfront choices in the first place.
首先不要在一开始就引诱用户做过多的选项。 -
On the forms that he does have to use, clearly mark the required fields, and don't make too many of them required. Let him move on without answering the optional ones.
表单里必填项要标出。(这里可以参考LukeW的ppt 《Best Practices for Form Design》) -
Sometimes you can separate the few important questions or options from others that are less important. Present the short list; hide the long list.
有时应该将少数的重点问题和次要的区分开来。显示短列表，隐藏长列表。 -
Use Good Defaults wherever possible, to give users some reasonable default answers to start with. But keep in mind that prefilled answers still require the user to look at them, just in case they need to be changed. They have a small cost, too.
选择合适的默认值（在《Designing the Obvious: A Common Sense Approach to Web Application Design )》同时提到。Nielsen博士也提到该点。） -
Make it possible for users to return to the deferred fields later, and make them accessible in obvious places. Some dialog boxes show the user a short statement such as "You can always change this later by clicking the Edit Project button." Some web sites store a user's half-finished form entries or other persistent data, like shopping carts with unpurchased items.
为用户返回他上次未完成内容的地方提供可能。并且把它摆放在明显的位置。 -
If registration is required at a web site that provides useful services, users may be far more likely to register if they're first allowed to experience the web site drawn in and engaged and then asked later about who they are. In fact, TurboTax 2005 allows a user to work through an entire tax form before creating a username.
如果一个提供有用服务的网站需要注册，用户也许会很喜欢先体验一把再注册的方案。
下内容节选自《Designing Interfaces》
1. safe exploration 安全地浏览
"Let me explore without getting lost or getting into trouble."
“别让我在浏览的时候迷路也别让我有困难。”
2. instant gratification 即时满足
"I want to accomplish something now, not later."
“我想现在就完成些事情，而不是以后。”
People like to see immediate results from the actions they take. it's human nature. If someone starts using an application and gets a "success experience" within the first few seconds, that's gratifying! He'll be more likely to keep using it, even if it gets harder later. He will feel more confident in the application, and more confident in himself, than if it had taken a while to figure things out.
人们喜欢在操作之后立马看到结果。这是人性。如果某人开始使用一个程序并且在头几秒内体验到了一个“成功”，那真是可喜的！ 即使使用这个程序会越来越难，但是他也很可能会继续。比起如果这程序需要一定时间才能理出头绪来，他会对程序对自己都更有信心。
3. satisficing 满意原则/够用就好（最佳设计100细则貌似提到过）
"This is good enough. I don't want to spend more time learning to do it better."
“这样就足够好了。我不想花再多的时间去学习它以便更好得使用它。”
This means several things for designers:
4. changes in midstream 中途改变
"I changed my mind about what I was doing."
“我曾经对我现在所做的事情改变想法。”
Occasionally, people change what they're doing in the middle of doing it. Someone may walk into a room with the intent of finding a key she had left there, but while she's there, she finds a newspaper and starts reading it. Or she may visit Amazon to read product reviews, but ends up buying a book instead. Maybe she's just sidetracked; maybe the change is deliberate. Either way, the user's goal changes while she's using the interface you designed.
用户偶尔改变一件正在做的事。
5. deferred choices 以后再说
"I don't want to answer that now; just let me finish!"
“我现在不想回答那些；以后再说！”
This follows from people's desire for instant gratification. If you ask a user several seemingly unnecessary questions while he's trying to get something done, he'd often rather skip the questions and come back to them later.
这是第二点即时满足的衍生。
For example, some web-based bulletin boards have long and complicated procedures for registering users. Screen names, email addresses, privacy preferences, avatars, self-descriptions…the list goes on and on. "But I just wanted to post one little thing," says the user plaintively. Why not skip most of the questions, answer the bare minimum, and come back later (if ever) to fill in the rest? Otherwise he might be there for half an hour answering essay questions and finding the perfect avatar image.
