因为这是一套不同的技能。成为网页设计师所需要的技能与成为程序员所需要的技能是不一样的。是的，很少有技能可能是重叠的，比如HTML, CSS, Javascript，但本质上程序员不知道是什么让一个网页设计成为一个好的网页设计，反之亦然。

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.

没有人建议过，但对你有很大帮助的是参加人因工程学课程(通常是研究生水平)。如果你不想选这门课，至少去找课本读一遍。

为什么UI设计对某些开发者来说如此困难?

这有点像问为什么篮球对足球运动员来说很难。

“好的UI设计”其实是两个问题:

获得正确的设计 正确的设计

两者都是难题。以我的经验来看，这两件事应该并行进行，这样才能避免在项目后期出现糟糕的惊喜(“为什么我们在IE8中拖放的速度非常慢??”你说它无法修复是什么意思??”)

为了得到正确的设计，你必须探索各种可能性。书籍可以引导你尝试对你的情况最有意义的事情-经验当然更好。此外，你绝对需要来自真实用户的反馈——否则你怎么才能发现设计已经是正确的呢?)你当然看不出来。继续阅读!)

“使设计正确”是下一个问题，因为这意味着必须执行你认为合适的设计。

那些“用户体验/图形用户界面”的事情是如此困难，因为找到正确的答案包括理解人类想要什么——他们不能客观地告诉你，而你也不能从“外部”找到。这意味着(经验)引导的试错方法是唯一可行的方法。

为了更清楚地回答你的问题:

为什么优秀的UI设计对某些人来说如此困难 重击

对于硬核开发人员来说，一个大问题是，他们对软件如何工作的理解与用户认为它如何工作的理解是非常不同的(例如，URL“www.stackoverflow.com”应该写成“com.stackoverflow.com”，如果你知道DNS如何工作的话。但试着销售一个浏览器，它期望url:))。

作为旁注:我建议你着眼于“体验设计”而不是“用户界面设计”，但这是另一个故事。

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。
