What Is UI: The Definition of User Interface in 200 Words or Less

为了简化UI是什么，我们将从隐喻开始。

Let’s say you go to a fancy new Italian restaurant and order a pasta dish. When it comes, you’re amazed with the presentation: the pasta is clustered in the center, with a light pink cream sauce drizzled over the top in a zigzag formation. There are two small green basil leaves in the center, and a few dots of pesto in the left corner.

In metaphor-world, the beautiful presentation of your meal is the responsibility of the UI designer, including the alignment of the elements (the pesto in the left, for instance), and interactivity as it relates to the user-experience (the light drizzling of the sauce so each bite is equally satisfying).

The UX designer, on the other hand, is responsible for everything as it relates to the larger business and your experience as their customer, including the smells and ambiance of the restaurant, the chef and waitstaff’s processes for cooking and delivering food, and the menu options.

While this is obviously a simplification, it corresponds well to the definition of UI. A UI designer is essentially in charge of how everything aligns on a page in relation to each other. She decides the hierarchy of the elements (“Should the logo be at the top or the bottom?”），以及整个产品的互动性（“Should the navigation be organized in scroll-down menus, or clickable buttons?”).

UI设计人员通常使用软件程序，网站和手机应用程序，但他们可能还将其bob电竞官方下载技能用于视频游戏或电视接口。

除非UI无效，否则您可能不会注意到UI。例如，如果您认为该网站看起来令人困惑，或者也许您嘲笑2002年PlayStation上的旧导航，也许您会避开网站。这些用户会感到不满意，并影响您与企业的互动。

相反，有效的UI在迫使您定期与企业互动方面大有帮助。例如，许多用户对约会应用程序有偏爱，例如Bumble与Hinge或乘车共享应用程序，例如Uber和Lyft。Those apps have different business models and services, so there are plenty of reasons you’d choose one over another -- but if you didn’t know anything about either, and I showed you two apps side-by-side, I’m guessing you’d intuitively gravitate towards one. Likely, an impressive UI design would cause that initial gravitation.
