Accessibility in infographics and data visualizations ensures that all users, including those with disabilities, can access and understand the information presented. This is not just a matter of compliance with accessibility standards like the Web Content Accessibility Guidelines (WCAG), but also an intrinsic element of inclusive design.

With that said, to truly make data-driven content accessible to all users, including those with visual impairments, following accessibility guidelines and design techniques is essential. In this short guide, we’ll examine proven techniques for creating accessible infographics and data visualizations that are inclusive and understandable to a wide audience.

Forms are commonly used to provide user interaction on websites and in web applications. For example, login, registering, commenting, and purchasing. This tutorial shows you how to create accessible forms. The same concepts apply to all forms, whether they are processed client or server-side.

Aside from technical considerations, users usually prefer simple and short forms. Only ask users to enter what is required to complete the transaction or process; if irrelevant or excessive data is requested, users are more likely to abandon the form.

Forms can be visually and cognitively complex and challenging to use. Accessible forms are easier to use for everyone, including people with disabilities.

  • People with cognitive disabilities can better understand the form and how to complete it, as making forms accessible improves the layout structure, instructions, and feedback.
  • People using speech input can use the labels via voice commands to activate controls and move the focus to the fields that they have to complete.
  • People with limited dexterity benefit from large clickable areas that include the labels, especially for smaller controls, such as radio buttons and checkboxes.
  • People using screen readers can identify and understand form controls more easily because they are associated with labels, field sets, and other structural elements.

When developing or redesigning a website or web application, evaluate accessibility early and throughout the development process to identify accessibility problems early, when it is easier to address them.

There are evaluation tools that help with evaluation. However, no tool alone can determine if a site meets accessibility standards. Knowledgeable human evaluation is required to determine if a site is accessible.

Most carousels come along with usability and accessibility issues. To avoid these issues, this article addresses step-by-step design considerations as well as semantic requirements for carousels to be accessible. It is intended to create an in-depth understanding of the implementation and its impact on users.

As widely used as they are, carousel widgets have a bad reputation among UX professionals. They are ignored by users (Nielsen Norman Group), only 1% interact with a carousel at all, and 89% of them only with the first slide (Eric Runyon). Jared Smith even responds to the question “Should I use A Carousel?” by saying, “Seriously, you really shouldn’t.” Others state that there isn’t one answer. You have to consider various factors, such as function, design, platform (desktop or mobile) and, most importantly, context. For whatever reason you include a carousel on a website, make sure it is user-friendly and accessible.
