There are many reasons why someone may experience varying degrees of visual, auditory, cognitive, neurological, physical, or speech issues that would interfere with their ability to use the web or IT products. Some may have disabilities from birth, an illness, disease, or accident. Some may develop impairments with age. Some may be temporarily impaired; others may have permanent or worsening conditions.
Rather than try to list every cause of every impairment, we design for a few major categories as broadly as possible.
- Auditory Disabilities
- Cognitive and Neurological Disabilities
- Physical and Motor Disabilities
- Speech Disabilities
- Visual Disabilities
- Complex or Compound Disabilities
Web Accessibility – Types of Disability by Coolfields Consulting outlines various types of disabilities (as listed above) as well as what features on the web can make life difficult for individuals with those types of disabilities.
