Accessibility in UX design is the practice of creating digital products and services for people with a wide range of abilities and disabilities. Accessibility solutions are critical to ensure all users can access and interact with digital content and applications regardless of their physical, cognitive, or sensory capabilities.
When you design for accessibility, you meet legal and ethical obligations, expand your potential customer base, and create more inclusive and engaging user experiences. This article explores guidelines and key best practices for designing accessible UX. These actionable insights will help you ensure everyone can easily access your digital products and services.
Accessibility in Design
Accessibility in design ensures individuals with visual, auditory, motor, or cognitive impairments can use your company’s websites, apps, and other digital offerings. Accessible designs benefit digital product users and providers in several ways, such as:
- They expand the potential user base.
- A cleaner, more intuitive interface improves the usability and experience for all users, not just those with disabilities.
- They demonstrate a company’s commitment to inclusivity and social responsibility, which can enhance both brand reputation and customer loyalty.
- They help organizations comply with legal requirements and accessibility standards to avoid potential lawsuits or fines.
Accessibility solutions in design also aim to accommodate a variety of disabilities, both permanent and temporary. For instance:
1. Visual Impairments
Blindness, low vision, color blindness, and other visual limitations hinder interaction with digital content. Accessibility features for visual impairments may include screen readers, high-contrast modes, and support for screen magnification.
2. Auditory Impairments
Users who are deaf or hard of hearing may struggle with audio-based content, such as videos or podcasts. Accessibility solutions for auditory impairments might provide captions, transcripts, or sign language interpreters.
3. Motor/Physical Impairments
Limitations in mobility, dexterity, or muscle control can make it hard for users to navigate and interact with digital interfaces. Accessibility for motor impairments may include support for keyboard-only navigation, voice controls, and adaptive input devices.
4. Cognitive Impairments
Certain conditions, such as dyslexia, ADHD, dementia, and other cognitive disabilities, can affect how users process and interact with digital information. Accessibility features for cognitive impairments may involve simplified language, straightforward navigation, and minimized distractions.
Understanding Accessibility Standards
The Web Content Accessibility Guidelines (WCAG) are the internationally recognized technical standards for making digital content and experiences accessible to people with disabilities. While it’s not a law, it includes vital criteria for developers and designers to remove barriers to access for digital users with disabilities.
There are different levels of accessibility requirements in terms of regulations and compliance. Your industry, business, and customer base will determine the appropriate level.
WCAG outlines four key principles that accessibility design solutions should adhere to:
- Perceivable: Information and user interface components must be presentable to users in ways they can perceive, whether through sight, hearing, or touch.
- Operable: User interface components and navigation must be operable. Users can interact with them through various input methods, such as a keyboard, mouse, or voice controls.
- Understandable: The content and operation of the user interface must be easy to understand for users of varying cognitive abilities.
- Robust: Content must be robust enough that it can be reliably interpreted by various user agents, including assistive technologies.
Best Practices for Accessible Design
Although not a conclusive list, here are some actionable guidelines for designing accessible user experiences:
- Ensure text content is easy to read and understand. Use clear language, proper formatting, and appropriate font sizes.
- Provide alternative text descriptions for all images, videos, and other non-text content.
- Ensure all interactive elements, such as buttons and links, are keyboard-accessible and have clear focus indicators.
- Provide captions and transcripts for all audio and video content.
- Provide ample time for users to complete form entries. You can remove time limits entirely or allow users to extend the time limit.
- Maintain consistent elements across all web pages, such as navigation, headers, footers, and sidebars. This helps users easily locate these elements on any page.
- Ensure your content has a well-organized, hierarchical structure that’s easy for screen reader users to navigate.
- Use proper contrast ratios between text and background colors to accommodate users with vision-related disabilities.
- Avoid design elements that could trigger seizures. Specifically, no website element should flash more than three times per second.
Tools and Resources for Testing Accessibility
WAVE and Lighthouse are two of many popular web accessibility testing tools. WAVE’s software identifies WCAG errors and evaluates web content with a suite of accessibility solutions. To start testing, you can enter a web page URL directly into the WAVE browser or use an extension on Chrome, Firefox, or Microsoft Edge.
On the other hand, Lighthouse is an open-source accessibility testing tool that automates testing in Google Chrome. It’s readily available in the Chrome Developer Tools, so it doesn’t require additional setup or extensions. Lighthouse can also be run as a Node module. This lets users integrate it into their continuous integration systems.
Lighthouse performs various WCAG requirement audits, such as missing alt text, low color contrast, and inconsistent header structures. After each audit, it scores your web accessibility and provides suggestions for improvement.
Another solution to enhance web accessibility are tools like the AccessiBe Access Widget—an AI-powered tool that automatically adjusts website elements like text size, contrast, navigation, and keyboard accessibility to meet WCAG 2.1 guidelines. Users can customize their browsing experience through an intuitive interface, making websites more accessible for individuals with visual impairments, motor disabilities, cognitive challenges, and more. By integrating the Access Widget, businesses can improve inclusivity, ensure compliance with accessibility standards, and provide a seamless experience for all users.
While automated accessibility testing tools are invaluable, they have limitations and shouldn’t be the sole way you evaluate accessibility. User testing with people with disabilities is essential to identify real-world accessibility issues automated tools may miss.
Best Practices for Accessibility Testing
Use the following best practices to test your accessibility solutions:
- Incorporate accessibility testing throughout the design and development lifecycle, not just at the end.
- Use automated tools and manual testing with users with diverse disabilities and assistive technology needs.
- Recruit a representative sample of users with visual, auditory, motor, and cognitive impairments to participate in usability testing and get their feedback on accessibility, usability, and overall experience.
- Address accessibility issues promptly and iterate on the design accordingly.
- Establish an ongoing accessibility testing program to monitor regressions and ensure continued compliance.
- Collaborate with experts who can help with audits, reviews, and accessibility solutions.
