- There is no generally-accepted, functional definition of “cognitive disability”.
- There has been little definitive research on creating Web sites for people with cognitive disabilities.
- The vast majority of related guidelines are not part of national- or world sets of Web accessibility standards.
- Making sites meet national- or world Web accessibility standards, by itself, is a lot of work.
- Because the scope of cognitive disabilities is so broad, the entire variety of needs can not be met even if all related guidelines are followed.
- Making Web site content accessible and providing alternate forms of content, which are necessary for people with cognitive disabilities, are typically outside the responsibility of designers.
- People with cognitive disabilities may also have physical- or sensory disabilities, which complicates efforts to make Web sites accessible to them.
- Web accessibility features (such as text-size enlargers and text-to-speech), which could benefit people with cognitive disabilities, may be a burden on other people, such as screen-reader users.
- It may be that no Web site can be made accessible to people with significant memory- and attention deficits, which are common characteristics of cognitive disabilities.
- Many people with cognitive disabilities, especially those with intellectual disabilities or Alzheimer’s Disease, do not have even basic computer skills.
Am I trying to make Web sites accessible to people with cognitive disabilities anyway? Yes, I am.
