For example, you may have thousands of images on your website that need to be checked for the presence of “alt text,” which is a requirement under WCAG 2.0. This is a task for automated testing software, which can perform the job much faster than any human. While automated tools can detect if the images on your website have alt text, however, they aren’t able to determine whether the text is correct and meaningful—which is a job for human testers.
The ADA guidelines are often updated so that businesses can better understand how various disabilities can affect the way that people will interact with websites and digital content. The guidelines also explain why certain barriers can prevent disabled individuals from using or even accessing a website. With these goals in mind, it is important to note that organizations need to review the guidelines on a yearly basis. New technologies, such as Artificial Intelligence10, are being used to help people with disabilities get the most out of the digital world. If organizations fail to read the latest ADA guidelines, then they will soon discover that their approach to web accessibility is outdated, and they might be in violation of digital accessibility laws.
Google and the government are already making asks around their expectations of accessibility as a cornerstone of website development. Google already rewards sites that check many accessibility boxes with higher rankings and the government has signaled that web accessibility standards will be required for government contractors. By building a more accessible website now, you may significantly impact your SEO and ranking potential, not to mention open the doors to possible work as a government contractor.
Technology is changing, and many website designers are using creative and innovative ways to present web-based materials. These changes may involve new and different access problems and solutions for people with disabilities. This Chapter discusses just a few of the most common ways in which websites can pose barriers to access for people with disabilities. By using the resources listed at the end of this Chapter, you can learn to identify and address other barriers.
Blind people, those with low vision, and people with other disabilities that affect their ability to read a computer display often use different technologies so they can access the information displayed on a webpage. Two commonly used technologies are screen readers and refreshable Braille displays. As discussed above, a screen reader is a computer program that speaks the text that appears on the computer display, beginning in the top-left corner. A refreshable Braille display is an electronic device that translates text into Braille characters that can be read by touch. These assistive technologies read text. They cannot translate images into speech or Braille, even if words appear in the images. For example, these technologies cannot interpret a photograph of a stop sign, even if the word “stop” appears in the image.
For close to seven years, since July of 2010, the United States Department of Justice (DOJ) has talked about issuing regulations specifically about web accessibility. At that time the US Department of Justice (DOJ) began developing accessibility guidelines for public websites under Title III of the Americans with Disabilities Act (ADA). On December 26, 2017, the Department announced that those regulations were officially withdrawn.
The words in the tag should be more than a description. They should provide a text equivalent of the image. In other words, the tag should include the same meaningful information that other users obtain by looking at the image. In the example of the mayor’s picture, adding an “alt” tag with the words “Photograph of Mayor Jane Smith” provides a meaningful description.
