Building Accessible UIs for Users with Cognitive Disabilities using Replay AI

TL;DR: Replay empowers developers to build more accessible UIs for users with cognitive disabilities by automatically generating code that reflects real-world user interactions observed in video recordings.

The Accessibility Gap in Modern UI Development#

Creating accessible user interfaces (UI) is not just a best practice; it's a necessity. However, designing for users with cognitive disabilities often falls through the cracks. Traditional accessibility audits primarily focus on visual and motor impairments, leaving a significant gap in addressing the needs of users with conditions like ADHD, dyslexia, or autism. These users may struggle with complex navigation, overwhelming visual stimuli, or inconsistent interactions. The key is understanding how they interact with your interface, not just what they see.

This is where a behavior-driven approach to UI development becomes crucial. Instead of relying solely on static design guidelines, we need to observe and adapt to real user behaviors. Replay offers a powerful solution to bridge this gap.

Behavior-Driven Reconstruction: Video as the Source of Truth#

Replay leverages the power of video analysis and AI to reconstruct working UIs directly from screen recordings of user interactions. This "behavior-driven reconstruction" approach allows developers to understand exactly how users navigate and interact with an interface, uncovering accessibility issues that might be missed by traditional methods.

Unlike screenshot-to-code tools that merely replicate visual elements, Replay analyzes the intent behind user actions. It understands the sequence of clicks, scrolls, and form entries, providing a holistic view of the user experience. This is particularly valuable for identifying usability barriers for users with cognitive disabilities.

How Replay Works:#

1. •Record User Interactions: Capture video recordings of users interacting with your existing UI or a prototype.
2. •Analyze with Replay: Upload the video to Replay's AI engine.
3. •Generate Code: Replay analyzes the video and generates clean, functional code, reflecting the observed user behavior.
4. •Iterate and Refine: Use the generated code as a starting point to build a more accessible and user-friendly UI.

Key Features for Accessibility-Focused Development#

Replay offers several key features that make it an invaluable tool for building accessible UIs for users with cognitive disabilities:

• •Multi-Page Generation: Replay can reconstruct multi-page flows, capturing the complete user journey and identifying potential points of confusion or frustration.
• •Supabase Integration: Seamlessly integrate Replay-generated code with your existing Supabase backend, streamlining the development process.
• •Style Injection: Apply consistent styling and branding across your UI, ensuring a cohesive and predictable user experience.
• •Product Flow Maps: Visualize the user's journey through your application, highlighting potential bottlenecks and areas for improvement.

Practical Implementation: Building an Accessible E-commerce Checkout Flow#

Let's consider a practical example: building an accessible e-commerce checkout flow. Users with ADHD might struggle with long, complex forms, while users with dyslexia may have difficulty reading small text or deciphering complicated layouts.

Step 1: Recording User Interactions#

Record video of several users with cognitive disabilities attempting to complete the checkout process on your existing website. Focus on capturing their struggles, hesitations, and any points where they get stuck or confused.

Step 2: Analyzing with Replay#

Upload the recorded videos to Replay. The AI engine will analyze the user interactions and identify patterns in their behavior.

Step 3: Generating Accessible Code#

Replay will generate code that reflects the observed user behavior. This code might include:

• •Simplified form layouts with clear labels and instructions.
• •Larger font sizes and increased spacing for improved readability.
• •Progress indicators to help users track their progress through the checkout process.
• •Clear error messages and helpful suggestions.

Here's a simplified example of code generated by Replay, focusing on form simplification:

typescript
// Replay-generated code - Simplified Checkout Form
const CheckoutForm = () => {
  return (
    <form>
      <div>
        <label htmlFor="name">Full Name:</label>
        <input type="text" id="name" name="name" placeholder="Your Full Name" />
      </div>
      <div>
        <label htmlFor="address">Shipping Address:</label>
        <textarea id="address" name="address" placeholder="Your Shipping Address"></textarea>
      </div>
      <div>
        <label htmlFor="payment">Payment Method:</label>
        <select id="payment" name="payment">
          <option value="creditCard">Credit Card</option>
          <option value="paypal">PayPal</option>
        </select>
      </div>
      <button type="submit">Complete Order</button>
    </form>
  );
};

export default CheckoutForm;

💡 Pro Tip: Pay close attention to the order of form fields. Group related fields together and prioritize the most important information.

Step 4: Implementing Accessibility Enhancements#

Review the generated code and identify areas where you can further enhance accessibility. Consider implementing the following:

• •ARIA Attributes: Add ARIA attributes to provide semantic information to assistive technologies.
• •Keyboard Navigation: Ensure that all elements can be accessed and interacted with using the keyboard.
• •Color Contrast: Use sufficient color contrast between text and background to improve readability.

Here's an example of adding ARIA attributes to the form:

typescript
// Replay-generated code with ARIA attributes
const CheckoutForm = () => {
  return (
    <form aria-label="Checkout Form">
      <div>
        <label htmlFor="name">Full Name:</label>
        <input type="text" id="name" name="name" placeholder="Your Full Name" aria-required="true" />
      </div>
      <div>
        <label htmlFor="address">Shipping Address:</label>
        <textarea id="address" name="address" placeholder="Your Shipping Address" aria-required="true"></textarea>
      </div>
      <div>
        <label htmlFor="payment">Payment Method:</label>
        <select id="payment" name="payment" aria-label="Payment Options">
          <option value="creditCard">Credit Card</option>
          <option value="paypal">PayPal</option>
        </select>
      </div>
      <button type="submit">Complete Order</button>
    </form>
  );
};

export default CheckoutForm;

📝 Note: This is a simplified example. A real-world checkout flow would likely involve more complex logic and validation.
