Accessible Tech: A Practical Guide for Everyone

Here’s a challenge for every professional: how can we ensure that the technology we use and create is truly accessible to everyone? From websites to software, accessibility isn’t just a nice-to-have; it’s a necessity. But how do we move beyond the buzzwords and implement concrete strategies that make a real difference?

Understanding the Principles of Accessible Design

Accessible design starts with understanding the core principles. It’s about creating experiences that are perceivable, operable, understandable, and robust (POUR). Perceivable means that information and user interface components must be presentable to users in ways they can perceive. Operable means that user interface components and navigation must be operable. Understandable means that information and the operation of the user interface must be understandable. Robust means that content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.

These principles, outlined in the Web Content Accessibility Guidelines (WCAG) developed by the World Wide Web Consortium (W3C), offer a framework for building accessible websites and applications. WCAG isn’t just a set of guidelines; it’s a living document that evolves with technology. The current version, WCAG 2.2, provides specific success criteria that define what it means for content to be accessible.

  • Provide text alternatives for non-text content: Images, videos, and audio files should have alternative text that describes their content.
  • Provide captions and other alternatives for multimedia: Captions are essential for people who are deaf or hard of hearing. Transcripts can also be helpful.
  • Make content adaptable: Ensure that content can be presented in different ways without losing information or structure. This includes using responsive design to adapt to different screen sizes.
  • Make it easier for users to see and hear content: This includes providing sufficient contrast between text and background, and allowing users to control the volume of audio content.
  • Make all functionality available from a keyboard: Many people with disabilities rely on keyboard navigation.
  • Provide users enough time to read and use content: Don’t impose arbitrary time limits on tasks.
  • Help users navigate, find content, and determine where they are: Provide clear and consistent navigation.
  • Make text content readable and understandable: Use plain language and avoid jargon.
  • Make content appear and operate in predictable ways: Avoid unexpected changes to the user interface.
  • Help users avoid and correct mistakes: Provide clear error messages and allow users to undo actions.

Based on my experience consulting with numerous organizations, the most common accessibility issues stem from a lack of understanding of these core principles. Many developers and designers are unaware of the specific requirements of WCAG and how to implement them in practice.

Implementing Accessible Web Design

Moving from theory to practice, how do we implement accessible web design? One crucial step is to use semantic HTML. Semantic HTML elements, such as `
