  • A (lowest)
  • AA (mid-range).
  • AAA (highest)

Physical Disability

  1. Test the consistency of voice recognition software to determine if it is available
  2. Check if the keyboard is easy to use for people with speech impairments
  3. Motorly disabled people should be able to seek human assistance in times of emergency
  4. For people with limited muscular control, test the application using a specially designed mouse
  5. As the user spends more time entering values into the form, make sure that the timeouts are set appropriately.

Cognitive Disability

  1. Make sure the controls are easy to use.
  2. Easy to understand menus that allow the user to select the items they require
  3. Maximize the use of graphs and images instead of text, which makes understanding context difficult
  4. You can test whether the user is able to complete a task without distractions such as alerts, advertisements, and so forth.
  5. Check if there are any options to get human assistance

Vision Disabilities

  1. Check if the application offers keyboard shortcuts to all operations performed by a mouse
  2. Convert text to audio
  3. For those with less vision abilities, magnifiers are available
  4. Fonts used must comply with the W3C Accessibility Checker rules
  5. Filters for color blindness

Hearing Disability

  1. You can test whether the app vibrates even when the feature is disabled (mobile apps).
  2. Sign language manuals are provided to aid in understanding the application.
  3. Mobile phones flash alerts, such as led lights flashing when incoming calls are made
  4. Convert audio to text in place
