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:
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。
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.
