材料设计与神秘肉导航问题 (Material Design and the Mystery Meat Navigation Problem)

In March 2016, Google updated Material Design to add bottom navigation bars to its UI library. This new bar is positioned at the bottom of an app, and contains 3 to 5 icons that allow users to navigate between top-level views in an app.

2016年3月，Google 更新了 Material Design，以在其UI库中添加底部导航栏。 这个新栏位于应用程序的底部，并包含3到5个图标，允许用户在应用程序的顶级视图之间导航。

Sound familiar? That’s because bottom navigation bars have been a part of iOS’s UI library for years (they’re called tab bars in iOS).

听起来有点熟？ 这是因为底部导航栏多年来一直是iOS UI库的一部分(在iOS中称为标签栏)。

Bottom navigation bars are a better alternative to the hamburger menu, so their addition into Material Design should be good news. But Google’s version of bottom navigation bars has a serious problem: mystery meat navigation.

底部导航栏是汉堡菜单的更好选择 ，因此将其添加到Material Design中应该是个好消息。 但是Google的底部导航栏版本存在一个严重的问题： 神秘的肉食导航 。

Whether you’re an Android user, designer, or developer, this should trouble you.

无论您是Android用户，设计师还是开发人员，这都将困扰您。

什么是神秘的肉类导航，为什么这么糟糕？ (What’s mystery meat navigation, and why’s it so bad?)

Mystery meat navigation is a term coined in 1998 by Vincent Flanders of the famous website Web Pages That Suck. It refers to buttons or links that don’t explain to you what they do. Instead, you have to click on them to find out.

神秘肉类导航是1998年由著名网站Web Pages Suck的 Vincent Flanders创造的一个术语。 它指的是没有向您解释其功能的按钮或链接。 相反，您必须单击它们才能找到。

(The term “mystery meat” originates from the meat served in American public school cafeterias that were so processed that the type of animal they came from is no longer discernible.)

(“神秘肉”一词起源于美国公立学校食堂提供的肉，这种食肉经过加工以至于无法辨别它们来自的动物类型。)

Mystery meat navigation is the hallmark of designs that prioritize form over function. It’s bad UX design, because it emphasizes aesthetics at the cost of user experience. It adds cognitive load to navigational tasks, since users have to guess what the button does. And if your users need to guess, you’re doing it wrong.

神秘的肉食导航是将形式优先于功能的设计的标志。 这是糟糕的UX设计，因为它以用户体验为代价强调美感。 由于用户不得不猜测按钮的作用，因此它增加了导航任务的认知负担。 而且，如果您的用户需要猜测，那就错了。
