Web Accessibility

Making Web Pages Accessible

The Internet and resources such as web sites, web applications, and digital content are some of the primary vehicles by which information reaches the Cal Poly Community. The central presence of the World Wide Web in delivering information and providing services is an essential reason to make its accessibility a priority for the university.

Over the next four years, Cal Poly Pomona will bring its web pages (campus administration, services, courses, instruction, programs and activities) into compliance with web accessibility standards and requirements.

Below are some items to keep in mind when developing or updating a new web site.

Vision Disabilities

Vision inadequate to see the monitor display

Users who are unable to usefully view the monitor display ordinarily use a piece of software called a screen reader, which renders in voice (or in some cases Braille or other output) the text of a web page. Screen readers linearize the contents of a web page, and they rely on there being text equivalents for every piece of non-text information (such as images) on the page.

Vision requiring magnification of the monitor display

Many users have visual impairments that require magnification of the screen contents. Most modern browsers can provide moderate text enlargement, and Internet Explorer 7 and Opera can magnify all elements of the page, including images, but for greater control of magnification, many users employ screen magnifiers, which have the added advantage of magnifying all applications, not just web browsers.

Color-blindness

Color blindness is a group of mainly genetic syndromes that reduce the ability to perceive colors. Although there is specialized software that attempts to enhance color differences that would otherwise be almost imperceptible, most users with color-blindness are best accommodated by not using color as the sole method of distinguishing information on a web page.

Hearing Disabilities

Audio

Many web pages are silent, and present no barrier to people with impaired hearing, but any audio on the page, be it voice, music, animal noises, or whatever, needs alternate text content.

Videos

Because video ordinarily involves synchronized audio and video tracks, it provides challenges for both people with vision problems and people with hearing problems. Many people who can't hear the sound track rely on closed captioning, and people who can't see the action use audio description.

 

Motor Disabilities

Every web page needs to be navigable by the keyboard. Some users with motor disabilities employ alternative keyboards, while others use standard keyboards. For keyboard users, navigation is accomplished by using shortcut keys to move through the page.
