Accessibility and PDF Table of Contents

Posted on:

This is the final installment of a three-part blog series on PDF and table accessibility. Please click here for Part One and Part Two. If there is a Bible for PDF accessibility, it is the 14th chapter of ISO 32000_2008, the ur-text of the PDF standard. For any Scripture, of course, there is commentary, and the latest is ISO 14298-1-2016. Nowhere in the core documents defining PDF accessibility is there any complete, definitive description of how to create a table of contents. That is why, when we review PDF tables of contents, there are so many variations in how they are… Read More

Tagging Complex Tables

Posted on:

Complex Tables are to be avoided at all cost, as I stated in yesterday’s post, The Trouble with Tables: A Brief Introduction. The reason is that they will create 3 to 6 hours of work apiece for authors, developers, or remediators.  I’ve spent a considerable amount of time searching my cache of problematic PDFs, looking for complex tables to use as an example, such as the following: This sure looks like a complex table, and it is – but only due to the author’s desire to attach two separate tables together.  A Section 508 remediator might send this back to the… Read More

The Trouble with Tables: A Brief Introduction

Posted on:

This is the first in a three-part series of blog posts that is dedicated to the many people in Government agencies who deal with PDF files on a daily basis, and encounter Section 508 requirements for these files. The Federal Government generates tens of thousands of PDF documents annually, and all of these must be made accessible. This task often falls to Section 508 departments, individual remediators, or even content authors. The goal of this blog series is to highlight special issues (and headaches) that you all will encounter. The topics I will be addressing will be based on some of… Read More

Indicating Link Purpose with ARIA

Posted on:

An Analysis on Different Screen Reader Behaviors Authors must avoid using the same text for links that retrieve different resources. Users without disabilities may be able to identify the links differently based on other page content; however, users with cognitive disabilities and users who are blind or visually impaired may have difficulty making the distinction when link text does not adequately describe each link’s purpose. For example, across a site, you have several links that direct users to view more information on a particular section, such as Read Review for a particular project. When there are multiple links of the same text,… Read More

Style Over Substance: The Content CSS Property and Accessibility

Posted on:

The content CSS property is an interesting property used in conjunction with either the :before or :after pseudo-elements that can insert text, symbols, and images into a web page from a stylesheet.  This property presents a number of issues for developers who understand the importance of making sure their work is accessible to people who use assistive technology.  Assistive technology allows people to use the power of the Internet even if they happen to be blind, or if they have cognitive, motor, or visual impairments. Developing a website that is accessible is not only the socially responsible thing to do,… Read More

How Windows Screen Readers Work on the Web

Posted on:

If you try to use a Windows screen reader on the web for the first time, you might find the experience to be daunting and confusing. This is because Windows screen readers introduce new access paradigms which do not always match what is displayed visually. Windows screen readers offer several modes to allow a user to review and interact with web content. Successfully using a screen reader on the web requires the user to be able to determine which mode is currently active, the operation paradigm for each mode, and how to switch modes as required. Developers also need to… Read More

How Browsers Interact with Screen Readers and Where ARIA Fits in the Mix

Posted on:

The differing behaviors of screen readers across various browsers are noticed all the time by screen reader users, and differing levels of ARIA support are noticed in a similar manner, but the reasons why this happens aren’t commonly understood by the majority of people. For example, the most widely used screen reader, JAWS, is hard coded to work best in Internet Explorer. The second most widely used screen reader, NVDA, is hard coded to work best in Firefox. This includes ARIA support. Here is the reason why. All browsers that support accessibility, include an Accessibility API that is built into… Read More

WebAIM Screen Reader Survey

Posted on:

SSB applauds WebAIM for their efforts to bring data to our community.  A great example is their recent survey on screen reader usage and preferences.  In May 2012, WebAIM conducted a survey of preferences of screen reader users. They received 1782 valid responses to this survey. This was a follow-up survey to the original WebAIM Screen Reader User Survey of January 2009 and the follow-up surveys from October 2009 and December 2010.  The survey was primarily distributed via Internet channels – email lists, social media, etc.  This would suggest that the majority of respondents who found out about and completed… Read More

Java Access Bridge Support – 64 Bit Windows

Posted on:
