. Although accessibility is mainly a developer task, sometimes the technical requirements required to preserve or enhance accessibility will affect the appearance of the website.
That means that design, copy, user experience and development all need to collaborate to make sure that navigation controls, forms, buttons, headings, buttons, links, and more are accessible.
People who are blind, visually impaired, illiterate or learning disabled use assistive technologies to navigate the Internet. Screen readers are the most common assistive technology for the web, these software programs attempt to interpret what is displayed on the web page and convey it to the user, usually through converting the text to speech but sometimes through a Braille output device. Screen magnifiers are also often used in conjunction with a screen reader. Typically a screen reader will attempt to parse the HTML from the top of the HTML file to the bottom and speak relevant elements to the user. Ideally the screen reader will allow the user to successfully move a virtual cursor down the page in order to fill out form fields, click buttons and make selections from drop-down menus and other controls.
To test thoroughly for accessibility you’ll need to ensure that the website or app performs well on each of the many screen readers available. There are several popular free and/or open source screen readers on each platform including JAWS, and NVDA.
Most web accessibility problems occur when the screen reader’s virtual cursor becomes trapped in a poorly designed form or skips over an important control or an important piece of textual information. Verifying that websites are indeed usable is similar to browser testing because each screen reader has different requirements and limitations. This is why understanding the behavior of each screen-reader is important. The needs of various screen readers can be accommodated by adding various special HTML tags to the important elements of the page.
This fall, the Department of Justice postponed its proceeding to adopt regulations on web accessibility for a few more years.
The prolonged delay in those regulations has created a perfect storm for more litigation under the Americans with Disabilities Act (ADA). As a result, many companies should be adding web accessibility to their list of top priorities for 2016.
Every once in a while a story surfaces involving a company that is forced to pay out big bucks because their website isn’t accessible to people with disabilities. People shake their heads and say “bad company,” but may not actually understand what online accessibility is and what they need to do to make their own websites more accessible. To remedy that, I asked online accessibility expert, Dennis Lembree, to be a guest and talk about what it means to be accessible.
