The compliance of scanned and OCRed files from Adobe Acrobat Pro with accessibility standards depends on several factors, especially when dealing with complex layouts like columns and tables. Here’s how these elements fare:

1. Text Recognition (OCR) Accuracy

  • Adobe Acrobat Pro’s OCR is generally reliable for converting scanned images into editable and searchable text.
  • Challenges with Columns: OCR might misinterpret multi-column layouts, reading them linearly rather than by column.
  • Challenges with Tables: OCR may struggle to preserve the structure of tables, often interpreting them as unstructured text.

2. Tagging and Accessibility

Acrobat Pro can automatically tag OCRed documents, but the tags may not always be accurate, especially for complex layouts:

  • Columns: Acrobat might not detect column order correctly, causing screen readers to read content in the wrong sequence.
  • Tables: The software often fails to generate proper table tags, leading to a loss of row and column relationships crucial for screen reader users.

3. Alt Text for Images

  • Scanned documents often include graphical elements, which Acrobat cannot automatically assign alt text to. You must manually add descriptive alt text for meaningful images.

4. Reading Order

  • Acrobat’s “Reading Order” tool is essential to correct the logical reading sequence, especially in multi-column and table-heavy documents.
  • Default reading order for OCRed files may require significant manual adjustments to ensure compliance.

5. Compliance with Accessibility Standards

To meet accessibility standards like WCAG 2.1 or Section 508, additional steps are often necessary:

  • Manually Adjust Tags: Verify and edit tags to accurately reflect document structure, including headings, lists, tables, and columns.
  • Use Acrobat’s Accessibility Checker: This tool helps identify and fix accessibility issues but may not catch all problems in complex layouts.
  • Supplement with Manual Efforts: Complex documents may require manual remediation with tools like Adobe Acrobat or third-party software specialized in accessibility.

Best Practices for Improving Compliance

  1. Pre-OCR Processing: Clean up scanned files to enhance OCR accuracy (e.g., ensuring straight scans, good contrast, and minimal noise).
  2. Use Proper OCR Settings: Select the correct language and enable the “Recognize as Table” option where applicable.
  3. Manually Review Tags: After OCR, manually inspect and adjust tags for accurate representation of document structure.
  4. Simplify Layouts: If possible, avoid overly complex layouts in scanned documents to minimize accessibility challenges.

By taking these additional steps, you can significantly improve the compliance of scanned and OCRed documents, even with complex layouts.

Accessibility

Resize table columns via the keyboard

A new command, list.resizeColumn, enables you to resize columns by using the keyboard. When you trigger this command, select the column you want to resize and provide a percentage of the width you want to set. The following video shows how to apply this to resize a column in the Keyboard Shortcuts editor.

Screen reader support for synthesizing chat responses

We’ve updated the accessibility.voice.autoSynthesize setting to enable screen reader users to opt in to hearing chat responses announced by our synthesizer, instead of getting aria alerts.

Debugging improvements

When you’re debugging with the focus in an editor, invoking the Debug: Add to Watch command now announces the variable’s value for screen reader users.

Additionally, the Debug accessibility help dialog was improved for better thoroughness.

Fonts for Dyslexia: Making Reading Easier for Everyone

In our increasingly text-heavy world, the importance of accessible design can’t be overstated. For people with dyslexia—a common learning difficulty that affects reading and writing skills—the right font can make a world of difference. Let’s dive into how certain fonts can boost readability for those with dyslexia and explore how this can be a game-changer, especially in higher education.

What is Dyslexia?

Dyslexia is a neurological condition affecting up to 10% of the population. It causes trouble with accurate and fluent word recognition, spelling, and decoding abilities. These challenges stem from difficulties in processing the phonological component of language, but it’s important to note that dyslexia is not related to intelligence. With the right support, dyslexic individuals can achieve amazing things.

The Magic of Dyslexia-Friendly Fonts

Dyslexia-friendly fonts are specially designed to address the unique challenges faced by dyslexic readers. Here’s what makes these fonts special:

  1. Heavier Bottoms: Letters with heavier bottoms help keep them from flipping upside down or swapping places.
  2. Larger Openings: Bigger spaces in letters (like the openings in ‘e’ and ‘a’) make similar-looking characters easier to tell apart.
  3. Unique Shapes: Distinct shapes for each letter reduce confusion between characters like ‘b’ and ‘d’ or ‘p’ and ‘q’.
  4. Consistent Letter Spacing: Consistent spacing between letters and words helps prevent the crowding effect, making reading smoother.
  5. No Italics: Italicized text can distort letters, making them harder to read for dyslexic individuals.

Popular Dyslexia-Friendly Fonts

  1. Dyslexie: Created by Christian Boer, who is dyslexic himself, this font includes all the essential features to reduce common reading errors.example of dylexie font
  2. OpenDyslexic: An open-source font designed to increase readability, with a heavy bottom to combat letter flipping and crowding.example of opendyslexic
  3. Sylexiad: This dyslexia-friendly font was developed by Robert Hillier from the dyslexic point of view and for adult dyslexic readers. As part of his research, observation and tests with non-dyslexic and dyslexic individuals, Hillier has found new knowledge within the field of dyslexia typographic research.This font includes a combination of handwritten style, long ascenders and descenders, uniform strokes, and generous word spacing.

  4. Lexend: A series of fonts developed based on research to reduce visual stress and improve reading performance.
  5. Arial and Verdana: Though not specifically for dyslexia, these clean, simple sans-serif fonts are often recommended due to their readability and ample spacing.

Transforming Higher Education

So, how can these fonts be utilized in higher education? Let’s break it down:

  1. Accessible Course Materials: Professors can use dyslexia-friendly fonts in their lecture slides, handouts, and digital resources. This small change can significantly enhance comprehension and reduce frustration for dyslexic students.
  2. Inclusive Exams and Quizzes: Designing exams and quizzes with these fonts ensures all students have a fair chance to perform well, leveling the playing field.
  3. Digital Platforms and Libraries: Universities can adopt dyslexia-friendly fonts on their websites, online learning platforms, and digital libraries, making resources more accessible to everyone.
  4. Communication: Emails, announcements, and other communications from the university can be made more readable with these fonts, ensuring that all students stay informed and engaged.
  5. Support Services: Disability support services can provide resources and training on how to use these fonts effectively, empowering students to customize their learning experience.

Real-World Impact

Implementing dyslexia-friendly fonts in higher education isn’t just a nice-to-have—it’s a necessity. Schools and universities that have adopted these fonts report better reading comprehension and less frustration among dyslexic students. This means a more inclusive and supportive learning environment where everyone can thrive.

Beyond Dyslexia: Universal Design

The benefits of dyslexia-friendly fonts extend beyond those with the condition. This approach is part of a broader concept known as universal design, which aims to make products and environments accessible to all, regardless of age, disability, or other factors. By prioritizing readability, we make content easier to digest for everyone, reducing eye strain and improving overall comprehension.

Fonts are more than just a design choice—they’re a critical component of effective communication. For individuals with dyslexia, the right font can transform reading from a struggle into an enjoyable experience. By embracing dyslexia-friendly fonts, especially in higher education, we take a big step toward creating a more inclusive world. So whether you’re a student, educator, or just someone who loves to read, consider the impact of font choice. It’s a simple change that can make a huge difference.
