  A Checklist for Designing Mobile Input Fields (archive)

</h1>
<section>
  <article>
    <h3><a href="http://www.nngroup.com/articles/mobile-input-checklist/">Source originale du contenu</a></h3>
    <p>Whether you're designing web pages, web-based applications (e.g., SaaS), or native mobile apps, one of the basic building blocks is the humble text-input field: a box where the user can enter some text. Uses of this widget are plenty and not the topic of this article. We should point out that there are many issues in application design relating to workflow and other big-picture questions that are important for good application user experience. (These topics are discussed in our full-day <a href="/courses/application-ux/">Application Design course</a>.)</p>

<p>In this article, we focus on the nitty-gritty of input fields. Each of these issues may seem minor, but we repeatedly see these usability guidelines violated — particularly in mobile user interfaces, where <a href="/articles/does-user-annoyance-matter/">even the smallest annoyance grows</a> from a molehill into a mountain in terms of its ability to delay users and prevent them completing tasks with your design.</p>

<p>Here's how an input field should look:</p>

<p><img alt="" height="87" src="//s3.amazonaws.com/media.nngroup.com/media/editor/2015/05/14/inputfield.png" width="200"/></p>

<p>Go through your design and complete the checklist for every single input field. Yes, this is work, but better you suffer than the users suffer.</p>

<p>Ideally, you'll have 100% checklist compliance for 100% of the input fields in your site or app. Anything less, and you do have a substandard user experience.</p>

<p>Pragmatically, you may not have resources to deliver 100% on these UX requirements. In that case, prioritize the fields so that the ones that are used the most or are the most critical for task completion get the highest scores.</p>

      Bonjour/Hi!
      Je suis <a href="/david/" title="Profil public">David&nbsp;Larlet</a>, je vis actuellement à Montréal et j’alimente cet espace depuis 15 ans. <br>
      Si tu as apprécié cette lecture, n’hésite pas à poursuivre ton exploration. Par exemple via les <a href="/david/blog/" title="Expériences bienveillantes">réflexions bimestrielles</a>, la <a href="/david/stream/2019/" title="Pensées (dés)articulées">veille hebdomadaire</a> ou en t’abonnant au <a href="/david/log/" title="S’abonner aux publications via RSS">flux RSS</a> (<a href="/david/blog/2019/flux-rss/" title="Tiens c’est quoi un flux RSS ?">so 2005</a>).

    <p>
      Je m’intéresse à la place que je peux avoir dans ce monde. En tant qu’humain, en tant que membre d’une famille et en tant qu’associé d’une coopérative. De temps en temps, je fais aussi des <a href="https://github.com/davidbgk" title="Principalement sur Github mais aussi ailleurs">trucs techniques</a>. Et encore plus rarement, <a href="/david/talks/" title="En ce moment je laisse plutôt la place aux autres">j’en parle</a>.
