Introduction to JAWS and Web Accessibility

Shawn Sandy (Ally.Cafe) ~ June 17, 2024

JAWS (Job Access With Speech) is one of the most widely used screen readers, developed by Freedom Scientific. It enables visually impaired users to read the content on their computer screens via text-to-speech or braille display. Ensuring that web content is accessible to JAWS is a critical aspect of web accessibility.

Why JAWS Accessibility Matters

User Independence: JAWS provides visually impaired users with the independence to navigate the web, read documents, and interact with digital content.
Compliance: Adhering to web accessibility standards ensures compliance with laws such as the Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act.
Enhanced User Experience: Accessible websites offer a better experience for all users, including those who rely on assistive technologies like JAWS.

WCAG 2.2 Guidelines for JAWS Accessibility

Adhering to WCAG 2.2 guidelines ensures that web content is accessible to JAWS users. These guidelines are divided into three levels of conformance: A, AA, and AAA.

Level A

1.1.1 Non-text Content: Provide text alternatives for all non-text content.

Example:
```
<img src="example.jpg" alt="Description of image">
```
2.1.1 Keyboard: Ensure all functionality is operable through a keyboard interface.

Example:
```
<button>Submit</button>
```

Level AA

1.4.3 Contrast (Minimum): Ensure a contrast ratio of at least 4.5:1 for text and images of text.

Example:
```
body {
  color: #333;
  background-color: #fff;
}
```
2.4.7 Focus Visible: Ensure that the keyboard focus indicator is visible.

Example:
```
button:focus {
  outline: 2px solid #00f;
}
```

Level AAA

1.4.6 Contrast (Enhanced): Ensure a contrast ratio of at least 7:1 for text and images of text.

Example:
```
body {
  color: #000;
  background-color: #fff;
}
```
2.4.9 Link Purpose (Link Only): Ensure the purpose of each link can be identified from the link text alone.

Example:
```
<a href="services.html">Our Services</a>
```

ARIA for JAWS Accessibility

ARIA (Accessible Rich Internet Applications) attributes enhance the accessibility of web content for JAWS users by providing additional semantic information.

Common ARIA Attributes

aria-label: Provides an accessible name for an element.

Example:
```
<button aria-label="Close">X</button>
```

aria-labelledby: Links an element to another element that labels it.

Example:

<label id="nameLabel">Name:</label>
<input type="text" aria-labelledby="nameLabel">

aria-live: Indicates that updates to an element should be announced by screen readers.

Example:
```
<div aria-live="polite">Updating content...</div>
```

Best Practices for JAWS Accessibility

Use Semantic HTML: Proper use of HTML5 elements ensures that JAWS can correctly interpret the content.
Provide Text Alternatives: Always use alt attributes for images, captions for videos, and text alternatives for other non-text content.
Ensure Keyboard Accessibility: All interactive elements should be navigable via keyboard.
Leverage ARIA: Use ARIA attributes to enhance the accessibility of dynamic content.
