我认为我们不能设计ui的原因是因为我们是完美主义者，不能决定什么时候足够好才是足够好。我知道我个人无法忍受UI设计，因为我总是怀疑自己，说:“不，那还不够好。”

让我直接说:

改善这一点并不是从指导方针开始的。首先要重新定义对软件的看法。

大多数硬核开发人员对他们软件的用户几乎没有同情心。他们不知道用户如何思考，用户如何建立他们使用的软件模型，以及他们通常如何使用计算机。

当专家和外行发生冲突时，这是一个典型的问题:一个正常人怎么会如此愚蠢，不明白专家10年前的理解?

首先要承认的一个事实是，几乎所有有经验的开发者都难以掌握:

正常人对软件的概念和你有很大的不同。他们完全不懂编程。一个也没有。零。他们根本不在乎。他们甚至不认为他们需要关心。如果你强迫他们，他们会删除你的程序。

这对开发者来说是难以置信的残酷。他为自己生产的软件感到自豪。他喜欢每一个特征。他可以告诉你它背后的代码是如何工作的。也许他甚至发明了一种令人难以置信的聪明算法，使它比以前快了50%。

用户并不关心。

真是个白痴。

许多开发人员无法忍受与普通用户一起工作。他们因为缺乏技术知识而感到沮丧。这就是为什么大多数开发人员回避，认为用户一定是白痴。

事实并非如此。

如果一个软件开发人员买了一辆车，他希望它能平稳运行。他通常不关心轮胎压力，机械微调是重要的，使它运行那样。在这方面他不是专家。如果他买了一辆没有微调功能的车，他就会把它退回去，再买一辆他想要的。

Many software developers like movies. Well-done movies that spark their imagination. But they are not experts in producing movies, in producing visual effects or in writing good movie scripts. Most nerds are very, very, very bad at acting because it is all about displaying complex emotions and little about analytics. If a developer watches a bad film, he just notices that it is bad as a whole. Nerds have even built up IMDB to collect information about good and bad movies so they know which ones to watch and which to avoid. But they are not experts in creating movies. If a movie is bad, they'll not go to the movies (or not download it from BitTorrent ;)

所以归结起来就是:把普通用户当成专家来回避是一种无知。因为在那些他们不是专家的领域(有这么多)，他们希望其他领域的专家已经考虑过使用他们产品或服务的普通人。

What can you do to remedy it? The more hardcore you are as a programmer, the less open you will be to normal user thinking. It will be alien and clueless to you. You will think: I can't imagine how people could ever use a computer with this lack of knowledge. But they can. For every UI element, think about: Is it necessary? Does it fit to the concept a user has of my tool? How can I make him understand? Please read up on usability for this, there are many good books. It's a whole area of science, too.

啊，在你说出来之前，是的，我是苹果粉;)

我认为这是因为一个好的UI是不符合逻辑的。好的UI是直观的。

软件开发人员通常在“直观”方面表现不佳

我相信所有CS程序员都有能力做出好的可用性设计，因为可用性设计要求开发人员按照特定的路径和规则进行思考。然而，对于一些程序员来说，开发一个好的“有吸引力的”设计几乎是不可能的。这并不意味着两者是不可避免地联系在一起的。这就像莫扎特能写出美妙的音乐，却不擅长足球。

我们是否可以做些什么来重新训练我们的大脑，使其更有效地设计出令人愉悦和有用的演示层?

是的。观察那些试图使用你的软件的用户，不要帮助他们。也被称为可用性测试。

The basic idea of usability testing is that you take someone with a similar background to your target audience, who hasn’t seen your software before and ask them to perform a typical series of tasks. Ideally they should try to speak out loud what they are thinking to give you more insight into their thought processes. You then watch what they do. Critically, you do not assist them, no matter how irresistible the urge. The results can be quite surprising and highly revealing. Usability testing can be very fancy with one way mirrors, video cameras etc, but that really isn’t necessary to get most of the benefits. There is a good description of how to carry out usability tests in Krug’s excellent book Don’t make me think: a common sense guide to web usability. Most of his advice is equally applicable to testing desktop applications.

一个有用的框架是积极地考虑你在设计一个沟通过程时所做的事情。在非常真实的意义上，你的界面是一种语言，用户必须使用它来告诉计算机该做什么。这导致我们考虑以下几点:

Does the user already speak this language? Using a highly idiosyncratic interface is like communicating in a language you've never spoken before. So if your interface must be idiosyncratic at all, it had best introduce itself with the simplest of terms and few distractions. On the other hand, if your interface uses idioms that the user is accustomed to, they'll gain confidence from the start. The enemy of communication is noise. Auditory noise interferes with spoken communication; visual noise interferes with visual communication. The more noise you can cut out of your interface, the easier communicating with it will be. As in human conversation, it's often not what you say, it's how you say it. The way most software communicates is rude to a degree that would get it punched in the face if it were a person. How would you feel if you asked someone a question and they sat there and stared at you for several minutes, refusing to respond in any other way, before answering? Many interface elements, like progress bars and automatic focus selection, have the fundamental function of politeness. Ask yourself how you can make the user's day a little more pleasant.

实际上，很难确定程序员认为界面交互是什么，除了交流过程之外，但问题可能是它根本没有被认为是任何东西。
