ADA Compliancy Following are some general suggestions
for helping to make your pages readable to all who view them.
|
-
Include captions for dialog or lyrics in videos (e.g., QuickTime) for
people who are deaf or hard of hearing.
-
Provide a transcript of any speech which is played back in audio (e.g.,
Real Audio).

-
Include captions for dialog or lyrics in videos (e.g., QuickTime) for
people who are deaf or hard of hearing.
-
Describe the function of images (such as buttons) using text
descriptions (alternate text). For example, a button link to the CSUB
home page might might be coded as <IMG SRC = "csublogo.gif" ALT = "Link
to CSUB"> (where csublogo.gif is the name of the image file and "Link to
CSUB" is the alternate text).
-
Use text descriptions to illustrate the appearance of important
graphical information, such as charts and diagrams.
-
Use verbal descriptions for video and animation.
-
Make sure that text and graphics can be understood when viewed without
color. Many visually impaired users set their own viewing "colors"
(black and white) to override document colors and backgrounds.
-
If you use text that blinks or scrolls, make sure the text movement can
be paused.
-
Use a text summary description of tables, and label rows and columns
using headers. Tables can be very challenging for "screen reading
software".
-
If you use tables to lay out a page, be aware that screen reading
software reads across each line one line at a time at a time. It does
not read an entire cell before moving to the next cell to the right. For
example, a table such as the following would not be easily understood.
The screen reader would read first the top line in each cell and then
the second line.
-
Provide a transcript of any speech which is played back in audio (e.g.,
Real Audio).

-
Make sure a person can understand the meaning of a page if advanced
multimedia features are turned off (e.g., Shockwave).
|
|
Try to create the page so a person can get around using the keyboard. This makes
it easier for people using speech recognition or pointing sticks.
-
Some individuals access the keyboard by pressing one key at a time. For
example, some users of mouth sticks use the numeric keypad to move the
mouse cursor. For example pressing down the number 9 on the numeric
keypad results in the mouse arrow moving up and to the right. Moving the
mouse in this manner requires a certain level of control. If targets are
very small, it is hard to direct the mouse pointer to stop on the link.
Some links are represented with small dots or small gifs that are hard
to stop accurately when using the keypad-mouse. A solution is to ensure
that links are text links, or if they are a picture, to ensure that the
image is not really small (e.g., a bullet dot).
-
People who use speech recognition to control the mouse, or a head
tracking device to control the mouse run into similar problems.
-
On a related note, low vision, blind and some users with learning
disabilities utilize the Tab key to move from link to link in a web
page. To be readable, links must be text links or include alternate
text.
|
|
Describe the meaning of the layout of complex pages. You can do this by labeling
each frame and describing the contents of the frame.
|
|
It is an excellent idea to always include a link near the top of the page which
takes the user to a text only version of your page. The link can be labeled
"Text only version of page". Although animation and multimedia effects on web
pages enhance the experience for many users, they can also make it very
difficult to read for individuals who use alternative access technologies.

The Trace Research and Development Center
Web site includes a Web page entitled "Designing
More Usable Web Sites" that contains links to various sites that address
accessibility issues. Among them are:
CSU-San Marco and CSU-Fresno provide comprehensive information and tools for
accessibility.
