How to Create Accessible Interactive Prototypes

Did you know over 1 billion people live with disabilities? Designing accessible prototypes ensures your digital products work for everyone.

Here’s a quick guide to creating accessible interactive prototypes:

  • Follow WCAG Guidelines: Ensure designs are perceivable, operable, understandable, and robust.
  • Use Accessibility Tools: Platforms like UXPin, Figma, and Sketch offer built-in accessibility features.
  • Address Common Issues: Fix low contrast, add alt text, enable keyboard navigation, and enlarge touch targets.
  • Test Accessibility: Use tools like WAVE and Lighthouse, and gather feedback from real users with disabilities.

WCAG for beginners – What are the Web Content Accessibility Guidelines?

Accessibility Standards and Guidelines

When creating interactive prototypes, it’s crucial to follow established standards like the Web Content Accessibility Guidelines (WCAG). These guidelines help ensure your prototypes are usable for people with different needs and abilities.

WCAG Guidelines for Prototypes

WCAG is based on four core principles, often referred to as POUR:

  • Perceivable: Make content visible and provide alternatives like text descriptions and sufficient contrast.
  • Operable: Ensure all features can be used with a keyboard and that interactive elements are straightforward to navigate.
  • Understandable: Design clear navigation and minimize user errors with predictable layouts.
  • Robust: Make sure your content works seamlessly with assistive tools like screen readers.

Common Accessibility Issues

Here are some frequent problems and how to address them:

Problem Solution
Low Color Contrast: Text may be hard to read for users with visual impairments Use tools like WebAIM‘s contrast checker to meet the 4.5:1 ratio
Lack of Keyboard Navigation: Excludes users who rely on keyboards Ensure logical navigation with the Tab key
Missing Alt Text: Screen readers can’t interpret images Add descriptive alt text for all visuals
Small Touch Targets: Hard for users with motor difficulties to interact Design buttons and elements at least 24×24 pixels in size

"Keyboard accessibility is one of the most important principles of Web accessibility, because no matter how radically different those devices are in appearance from standard keyboards."

To avoid these issues, start accessibility testing early in your design process. Tools like WAVE and AChecker can identify potential barriers before they become ingrained in your prototype. Testing with real users who depend on assistive technologies also provides valuable insights for improving accessibility.

Tools and Setup for Accessible Prototypes

Modern prototyping platforms make it easier to design with accessibility in mind, thanks to their built-in features.

Choosing the Best Tools

When picking a prototyping tool, look for ones that prioritize accessibility. For example, UXPin includes a Contrast Analyzer and Color Blindness Simulator, allowing designers to focus on inclusivity right from the start.

Here’s a quick comparison of popular prototyping tools and their accessibility-focused features:

Tool Key Accessibility Features Best For
UXPin Contrast Analyzer, Color Blindness Simulator, WCAG checker High-fidelity interactive prototypes
Figma Auto-layout, Component libraries, Smart Animate Collaborative design workflows
Sketch Vector editing, Symbols library, Accessibility plugins MacOS users, Design system creation

Setting Up Your Tools

1. Turn On Accessibility Features
In UXPin, activate the Contrast Analyzer to ensure text contrast aligns with WCAG standards (4.5:1 for normal text, 3:1 for large text).

2. Use Pre-Built Components
Leverage accessible components from libraries. UXPin’s React libraries, like MUI, Tailwind UI, and Ant Design, include ARIA support and built-in accessibility.

3. Install Testing Plugins
For Figma users, adding the "A11y – Color Contrast Checker" plugin helps validate color combinations throughout the design process.

With your tools ready, focus on building a design system that promotes accessibility and consistency across all prototypes.

Building an Accessible Design System

Following WCAG’s Perceivable and Understandable principles, start by defining these key elements:

Color Palette Setup

  • Ensure your color system meets WCAG contrast ratios (at least 4.5:1 for text).
  • Provide alternative palettes to accommodate users with color blindness.

Typography Standards

  • Set a minimum font size of 16px for body text and establish clear heading hierarchies.
  • Define line heights and letter spacing to improve readability.

"Just because there’s a bare minimum doesn’t mean we should strive for that. Designing accessibly serves all users better."

Building Accessible Interactive Elements

Interactive elements are a key part of prototypes, and making them accessible ensures that your designs work for everyone. Here’s a closer look at three key interaction methods: keyboard navigation, screen reader support, and touch interfaces.

Keyboard Controls

Keyboard navigation is essential for users who rely on keyboards, such as those with motor impairments or those who simply prefer it.

  • Focus Indicators: Make sure interactive elements have visible focus indicators, like a 2px outline. In UXPin, you can adjust these to meet WCAG guidelines.
  • Navigation Flow: Ensure the tab order mirrors the visual layout and allows users to exit components smoothly using the keyboard.
Key Command Function
Tab/Shift+Tab Navigate between interactive elements
Arrow Keys Move within composite controls
Enter/Space Activate buttons and links
Esc Exit modals or expanded menus

Keyboard navigation ensures users can interact with content, but screen reader compatibility is just as important for accessibility.

Screen Reader Compatibility

Screen readers depend on proper semantic structure and clear descriptions to interpret your prototype effectively.

  • ARIA Labels: Add ARIA labels to clarify interactive elements. For example: <button aria-label="Submit form">Continue</button>.
  • Content Structure: Use semantic HTML and logical heading levels (H1-H6) to help screen readers guide users through the content.

Touch interfaces, another critical area, require thoughtful design to accommodate different user needs.

Touch and Visual Elements

For touch interactions, follow WCAG’s minimum touch target size of 24x24px, though 44x44px is often better for usability.

  • Visual Feedback: Provide clear feedback for interactions, like hover states with a 3:1 contrast ratio or touch animations under 400ms.

"A clear visual indication of keyboard focus is an important usability aid for all keyboard users, especially those with low vision".

"If focus is moved to a component of the page via the keyboard, then that focus should be able to exit that component also using the keyboard".

Testing Accessibility Features

Testing ensures your prototype works well for everyone, meeting both technical standards and user needs. This involves using automated tools, manual checks, and direct feedback from users to identify and fix accessibility problems.

Running Accessibility Tests

Automated tools like WAVE and Lighthouse are great for spotting issues such as missing ARIA labels or poor keyboard navigation. They provide valuable insights into how well your prototype aligns with accessibility guidelines.

Testing Tool Purpose Key Features Checked
WAVE Analyzes structure ARIA labels, semantic HTML
Lighthouse Checks performance Color contrast, keyboard navigation
Screen readers Tests content usability Text alternatives, heading structure

While these tools are helpful, combining them with real user testing ensures your prototype accommodates a wide range of needs.

Testing with Target Users

Invite users with different accessibility requirements to test your prototype. This helps uncover barriers in navigation and interaction:

  • Screen reader users can evaluate content hierarchy and interactive elements.
  • Keyboard-only users help identify navigation challenges.
  • Users with visual impairments (e.g., color blindness or those using screen magnifiers) can assess visual accessibility.

"A clear visual indication of keyboard focus is an important usability aid for all keyboard users, especially those with low vision".

The feedback from these sessions is invaluable for addressing gaps and improving accessibility.

Making Improvements

Address the most pressing issues highlighted during testing:

  • Adjust keyboard navigation paths based on user input.
  • Improve ARIA labels and ensure a clear structure for screen readers.
  • Use tools like UXPin to validate changes and ensure progress.

Accessibility testing is not a one-time task. Regular checks throughout the design process make it easier to catch and fix issues early.

Conclusion

Why Accessible Design Matters

Accessible design ensures digital interfaces work for everyone, not just individuals with disabilities. By focusing on accessibility during the design process, teams create solutions that are more user-friendly for all.

Prototyping tools play a key role here. They allow designers to address accessibility issues early, especially for complex interactive elements that require multiple input methods.

"WCAG is the floor, not the ceiling"

Steps to Get Started

Heuristic Evaluation – 5 Usability Principles to Help Guide Your Work

5 user experience principles to help guide your work

Heuristic evaluation is the review of a user interface based on a set of usability principles.

It helps surface usability problems throughout the design process and can save countless hours of development time by fixing usability issues before they go live.

A formal heuristic evaluation consists of 3–5 usability experts examining an interface to highlight potential issues based on their guidelines.

This article was written by Andrew Coyle from NextUX. NextUX can accommodate your workflow in UXPin by enabling anyone on your team to quickly capture a screenshot and add markup directly on top of it.

Jakob Nielsen and Rolf Molich pioneered heuristic evaluation in the 90s, and their usability heuristics for user interface design still serve as a guide today. I highly recommend memorizing their 10 heuristics and learning more about how to conduct a heuristic evaluation.

Throughout my experience as a designer, I’ve defined and refined the heuristics I use to review web projects. Although I weigh countless variables and best practices when evaluating a UI, these 5 principles best encompass how I assess designs.

Apply knowledge in practice. Use UXPin to design advanced prototypes that look and feel like an end-product. With UXPin, it’s so easy to transform a vague idea into a functional prototype that can be sharable with other team members. Try UXPin for free.

Users should know where they are

The user should always know where they are in an interface and understand how to navigate where they need to go. Establish straightforward navigation and sign markers throughout your app or website. Also, make your design interactive to thoroughly check what may cause troubles in the final product. 

Example: Add an indication of progress and state in stepped flows and provide a descriptive header to communicate where they are and what’s next.

Rule exception: If the user derives entertainment or value from discovering where they are or what’s next, like in a game.

sign-up form better version

Make user interfaces consistent and aesthetically pleasing

Elements and flows in a user interface should be consistent with each other.

Example: A design using a sentence case for some buttons and a title case for others is most likely violating this principle unless there is an overriding stylistic reason for the inconsistency.

I believe the value placed on different aesthetic styles is in the beholder’s eye, but the overall aesthetic appeal is not. How a creator uses balance, symmetry, hierarchy, and other visual principles can make universally pleasing designs.

Example: An interface with a lot of visual noise caused by unnecessary borders and drop shadows reduces aesthetic appeal and, in turn, usability.

consistent interface in design

Reduce the need to read, wait or memorize

“If you make me read, I leave.”

“If you make me wait, I leave.”

“If you make me think, I leave.”The user

Unfortunately, people have extremely low attention spans when it comes to the digital world. Never rely on a user to read, wait, or memorize anything. Always omit unnecessary text and design for scannability.

Automate as much as possible, so the user doesn’t need to rely on their short-term memory. 

Example: If your app has a long load time for specific processes or interactions, consider adding a fun loading animation with an indication of time left to ease the burden of waiting.

Example: If your app has a complicated setup process, don’t assume the user will read instructions or memorize requirements. Instead, break up a long setup process into short steps with concise and contextual information.

Solution to complicated setup process

Prevent errors and make actions reversible

Reduce the potential for errors by creating safeguards and clear communication in your application.

Example:

  1. Make deleting important data a more dexterous interaction to reduce inadvertent deletions.
  2. Add extra steps to the deletion process and make sure the user knows the outcome of their action.
  3. Add the ability to undo critical actions.

Enable experienced users and accommodate new users 

Don’t overwhelm new users with complexity and choices. Provide a great first-time use experience that gets a user up to speed as fast as possible.

In making a powerful application easy to use, don’t limit the ability of experienced users. Provide optionality and customization for frequent users to achieve their goals and solve their needs as quickly as possible.

Example: Add keyboard shortcuts to actions presented in a user interface. New users don’t need to know the keyboard shortcuts to interact, but experienced users can interact faster with the shortcuts.

Use these usability principles to improve product design

I hope these 5 principles help you evaluate designs. Together we can build a better user experience! If you’re looking for an end-to-end design tool, use UXPin. Design, iterate, and deliver a prototype 10x faster. Try UXPin for free.
