>Cognitive and language impairments include dyslexia and problems with; memory, comprehension, problem solving,
|
|
and written language.
|
|
For many individuals with cognitive and language disabilities, complex graphical displays and inconsistent use of words
|
|
can make using the computer more difficult.
|
|
A user with epilepsy can have a seizure from an application with blinking lights and animation. Most desktops now allow users to
|
|
disable animation. Web browsers such as Mozilla and Netscape allow users to disable graphics. It is important to
|
|
check the documentation for preferences that are available in the desktop environment you are using,
|
|
as well as any applications that are
|
|
used. This section discusses the tools that are available to aid users with these impairments:
