移动用户体验提万博官网manbetx下载高可用性指导原则

通过 雅各布·尼尔森November 7,二千零一十一

总结:移动和桌面设计有许多类似的指导方针,manbetx官方网站手机版但他们的手机翻译更为无情。


我最近的专栏移动内容:如果有疑问,Leave It Out建议网站所有者在为移动用户写作时删除辅助材料。Many tweets,blog postings,以及其他关于这篇文章的评论都是围绕这个主题展开的:对,do cut the fluff from mobile content,but在为桌面网站写作时,也要减少次要内容。

一方面,我只能同意。Since 1997,简洁性是一个重要的指导方针when writing for the web.人don't read a lot on the weband几秒钟后离开if a site doesn't communicate its value clearly.这些发现导致了更详细的指导方针,如强调前两个词纳米含量(例如,标题和搜索引擎链接)。

所以,是的,cut the blah-blah从您的桌面站点。

手机比台式机更不宽容

然而,there's still a difference between writing for the web and writing for mobile:

  • 桌面文案必须简洁。
  • 移动文案必须甚至更多简洁的。

The high-level guideline is the same: reduce secondary info.Thedifference is one of degree— certain information that might be acceptable on a desktop site应该从移动网站或应用程序。

Our original人们如何在移动设备上阅读的研究使用了向用户发送带有特殊优惠的优惠券的示例。In the study,the best manbetx官方网站手机版design presented fairly limited information on the first screen.要阅读“关于这笔交易的更多信息”,用户必须点击一个链接。

在桌面设计中,manbetx官方网站手机版最好是在第一个屏幕上显示所有信息,并保存用户点击。Why this difference?

  • 手机screens are much smaller: reading through a peephole increases cognitive load and makes it abouttwice as hard to understand texton a mobile device as on a desktop.Short-term memory is weak,so the more users have to remember after it scrolls off the screen the worse they'll do.
  • Mobile users are更为匆忙than desktop users because of the mobile setting.

Both differences support the same recommendation:更加严厉当为手机而不是桌面剪切文本时。

类似的发现也适用于功能的选择:功能集应该小得多for a mobile site than for a desktop site.For sure,desktop sites should offeras few features as possible.For every feature that's removed,the UI has one less thing to confuse users and thus makes the remaining features easier to use.

但是移动网站应该更少的功能than the desktop site.(Thus the guideline to offer a link from the mobile site to the full site for users who need features that only the desktop site supplies.) The mobile site should have only those features that make sense for the mobile use case.For example,a company's full site typically includes公关信息and投资者关系科,but this info should be eliminated from the mobile site.

Your desktopinformation architecture (IA)应始终具有一个简单的导航空间,以避免层次过深。But for mobile,the limited space makes it even more important to prevent user disorientation;you should thus limit the navigation options,因为你不能在每个屏幕上显示完整的上下文信息。(分配给典型桌面站点导航的总屏幕空间为more比典型智能手机的整个屏幕,没有空间放内容。)也就是说,您导航结构应该更浅in a mobile IA.

Tablets form an intermediate casesomewhere between phones and desktops.Tablets' mid-sized screens allow for more context in both writing and navigation than what fits on mobile screens and also supports richer features.On the other hand,空间越大,手势就越复杂,which leads to its own usability problems,在我们的research with iPad users.

可用性准则很少有两分法。

人们希望我给出严格而快速的规则:不要表现得超过X菜单项;don't write more thanYwords per page;nothing should be more thanZ点击主页。悲哀地,UI设manbetx官方网站手机版计不是这样工作的。可用性问题很少只有一个答案。Rather,they are qualitative issues thatspecify the direction and nature of inevitable manbetx官方网站手机版design tradeoffs.

每次你的网页响应时间增加0.1秒,你会失去百分之几的访客。但这不是真的每个人将等待10秒nobody将等待11秒。

作为另一个例子,take the guideline about concise writing.最简洁的副本是一两个字,但这通常会导致网页不令人满意。事实上,sometimes longer manbetx官网手机登陆articles can be better(though even in-depth manbetx官网手机登陆articles should cut the fluff and be written at an appropriate理解水平for their target audience).

简单的一点是:在为网络写作时最好压缩文本Web内容准则)If writing for mobile,simply squeeze that orange even more.When considering which secondary content to defer to secondary pages,当面向移动用户时,您需要在主要用户和次要用户之间移动截止点。The principle remains the same,但你对手机的判断力应该更高。

在用户体验的所有领域-功能集,IAwriting,图像,and more — mobile usability requires stricter and more scaled-back manbetx官方网站手机版design than desktop usability.这就是为什么你需要separate mobile manbetx官方网站手机版design.Simply using responsive web manbetx官方网站手机版design to make the full site accessible on mobile devices results in a substandard mobile 万博官网manbetx下载UX.(这实际上是对新媒体重复的一个老教训:可访问性≠可用性.)
